The Fiber Factor: Your Secret Weapon for Metabolic Health

In the complex world of nutrition advice, one recommendation stands out with remarkable consistency across medical research and clinical practice: eat more fiber. For individuals managing diabetes or working toward sustainable weight loss, dietary fiber emerges as perhaps the most powerful nutritional tool available—yet it remains chronically under-consumed in modern diets.

The average American consumes merely 15 grams of fiber daily, falling drastically short of the recommended 25-38 grams. This fiber deficit contributes significantly to the epidemic of metabolic disorders, weight gain, and blood sugar dysregulation affecting millions worldwide.

Fiber, the indigestible portion of plant foods, offers extraordinary benefits that extend far beyond digestive regularity. For people with diabetes, fiber slows glucose absorption, preventing dangerous blood sugar spikes. For those pursuing weight loss, fiber increases satiety, reduces calorie intake, and supports the metabolic processes that facilitate fat burning. Most remarkably, these benefits come without medication side effects, complicated protocols, or significant expense—just real, whole foods.

This comprehensive guide explores the top doctor-recommended high-fiber foods, with specific focus on fiber-rich fruits and green vegetables. You'll discover not just what to eat, but why these foods work, how to incorporate them strategically, and how to maximize their metabolic benefits for blood sugar control and sustainable weight management.

Understanding Fiber: Soluble vs. Insoluble

Before diving into specific foods, it's important to understand that not all fiber is created equal. Dietary fiber divides into two categories, each offering distinct benefits:

Soluble Fiber dissolves in water, forming a gel-like substance in the digestive tract. This type of fiber is particularly valuable for blood sugar control and cholesterol management. It slows the absorption of sugar into the bloodstream, preventing the rapid spikes that challenge diabetics and trigger insulin resistance. Soluble fiber also binds to cholesterol particles, helping remove them from the body. Foods particularly rich in soluble fiber include oats, beans, apples, citrus fruits, and psyllium.

Insoluble Fiber doesn't dissolve in water and passes through the digestive system relatively intact. This fiber adds bulk to stool, promotes regularity, and feeds beneficial gut bacteria. While less directly involved in blood sugar control, insoluble fiber supports weight loss by increasing satiety and promoting healthy gut microbiome diversity. Green vegetables, wheat bran, and the skins of many fruits provide abundant insoluble fiber.

For optimal health, particularly when managing diabetes or pursuing weight loss, both types are essential. Fortunately, most high-fiber whole foods contain a mix of both soluble and insoluble fiber, making it unnecessary to track them separately when eating a varied plant-based diet.

How Fiber Supports Blood Sugar Control

For individuals with diabetes or prediabetes, fiber functions as a natural blood sugar regulator through several mechanisms:

Slowed Glucose Absorption: Soluble fiber creates a viscous gel in the intestines that slows the breakdown and absorption of carbohydrates, resulting in gradual rather than rapid increases in blood glucose. This prevents the dangerous spikes that damage blood vessels and nerves over time.

Improved Insulin Sensitivity: Research published in Diabetes Care demonstrates that high-fiber diets improve insulin sensitivity, meaning cells respond more effectively to insulin's signals to take up glucose from the bloodstream. This reduces the amount of insulin needed to manage blood sugar levels.

Reduced Glycemic Load: High-fiber foods typically have lower glycemic indices, meaning they cause smaller, slower rises in blood sugar compared to low-fiber refined foods. The fiber content effectively reduces the glycemic impact of the entire meal.

Enhanced Incretin Response: Fiber stimulates the release of incretin hormones from the intestines, which help regulate insulin secretion in response to food intake, improving overall glycemic control.

Multiple studies confirm these benefits. A meta-analysis in the Journal of the American Board of Family Medicine found that each additional 10 grams of daily fiber intake reduced HbA1c levels (a measure of long-term blood sugar control) by approximately 0.25%—a clinically meaningful improvement that reduces diabetes complications risk.

How Fiber Facilitates Weight Loss

For sustainable weight loss, fiber offers advantages that no pharmaceutical intervention can match:

Increased Satiety: Fiber-rich foods are more filling than refined alternatives, reducing overall calorie intake without conscious restriction. Research in Nutrition Reviews found that increased fiber intake was associated with significant weight loss even without deliberate calorie restriction.

Reduced Calorie Absorption: Some fiber types slightly reduce the digestibility and absorption of other nutrients, effectively lowering the caloric value of meals.

Gut Microbiome Support: Fiber serves as food for beneficial gut bacteria, which produce short-chain fatty acids that may influence metabolism, inflammation, and fat storage. A healthy microbiome is increasingly recognized as crucial for weight management.

Hormonal Regulation: High-fiber diets favorably influence hunger and satiety hormones including ghrelin, leptin, and peptide YY, helping regulate appetite naturally.

Stabilized Energy: By preventing blood sugar crashes that trigger cravings and overeating, fiber helps maintain steady energy and reduces the impulse to consume high-calorie foods.

A landmark study in the Annals of Internal Medicine found that simply increasing fiber intake to 30 grams daily—without other dietary changes—resulted in significant weight loss comparable to more complex diet interventions.

Top High-Fiber Fruits for Diabetes and Weight Loss

Fruits often face undeserved scrutiny in diabetes and weight loss contexts due to their natural sugar content. However, high-fiber fruits provide essential nutrients, antioxidants, and satisfaction that support metabolic health when consumed appropriately.

Berries: The Low-Sugar Fiber Champions

Raspberries lead all fruits in fiber content, delivering an impressive 8 grams of fiber per cup with only 64 calories and 5 grams of net carbohydrates (total carbs minus fiber). Their low glycemic impact makes them ideal for blood sugar management. Raspberries contain powerful antioxidants including ellagic acid and anthocyanins that reduce inflammation and oxidative stress associated with diabetes complications.

Blackberries provide 7.6 grams of fiber per cup with similar low glycemic properties. They're particularly rich in vitamins C and K and contain compounds that may improve insulin sensitivity.

Strawberries, while containing slightly less fiber at 3 grams per cup, offer excellent nutritional density with minimal blood sugar impact. Their high vitamin C content supports immune function often compromised in diabetes.

Blueberries deliver 3.6 grams of fiber per cup alongside remarkable cognitive and cardiovascular benefits. Research suggests their anthocyanins may improve insulin sensitivity and glucose metabolism.

Practical Application: Berries make excellent snacks, breakfast additions, or dessert alternatives. Their fiber-to-sugar ratio prevents blood sugar spikes while satisfying sweet cravings. Frozen berries retain nutritional value and provide year-round affordability.

Apples: The Soluble Fiber Powerhouse

The saying "an apple a day keeps the doctor away" holds particular truth for diabetes and weight management. A medium apple with skin provides approximately 4.4 grams of fiber, with significant pectin content—a soluble fiber exceptionally effective for blood sugar control and cholesterol reduction.

Research in the Journal of Functional Foods found that apple consumption improved glycemic control and reduced inflammation markers in individuals with type 2 diabetes. The key is eating the whole fruit with skin intact, where much of the fiber and polyphenol antioxidants concentrate.

For weight loss, apples' high water content combined with fiber creates substantial satiety for minimal calories (approximately 95 calories for a medium apple). Studies show that eating an apple before meals can reduce overall calorie intake by promoting fullness.

Practical Application: Choose tart varieties like Granny Smith for the lowest glycemic impact. Eat apples with their skin, perhaps paired with a protein source like almond butter to further stabilize blood sugar response.

Pears: The Underappreciated Fiber Source

Pears rival apples in fiber content, providing approximately 5.5 grams per medium fruit. They contain both soluble and insoluble fiber, with particularly high pectin concentrations that support blood sugar regulation.

Research indicates that regular pear consumption is associated with lower body weight and reduced risk of metabolic syndrome. The fruit's high water content (about 84%) combined with fiber creates exceptional satiety relative to caloric content.

Practical Application: Like apples, pears should be eaten with skin for maximum fiber benefit. Their natural sweetness satisfies dessert cravings while providing nutritional value that processed sweets lack.

Avocados: The Unique Fiber-Fat Combination

Though often overlooked as a fruit, avocados provide an extraordinary nutritional profile for diabetes and weight management. One medium avocado delivers approximately 10 grams of fiber—more than most other fruits—combined with heart-healthy monounsaturated fats that enhance satiety and support cardiovascular health often compromised in diabetes.

Studies published in Nutrition Journal found that including avocado in meals significantly increased satiety and reduced desire to eat for up to five hours. The combination of fiber and healthy fat slows digestion and stabilizes blood sugar remarkably well.

Despite their higher calorie content (about 240 calories per avocado), research suggests avocado consumption supports rather than hinders weight loss, likely due to their exceptional satiety effects and beneficial impact on metabolism.

Practical Application: Half an avocado makes an excellent addition to salads, whole grain toast, or as a creamy base for smoothies. The combination of fiber, healthy fats, and minimal sugar creates ideal metabolic effects.

Oranges and Grapefruit: Citrus Fiber Stars

Whole citrus fruits (not juice) provide excellent fiber alongside vitamin C and beneficial plant compounds. A medium orange delivers approximately 3 grams of fiber, while grapefruit provides about 2 grams per half.

Grapefruit has garnered particular attention for weight loss. A study in Metabolism found that eating half a grapefruit before meals resulted in significant weight loss and improved insulin resistance. The combination of fiber, low energy density, and potentially beneficial compounds like naringenin creates favorable metabolic effects.

Critical Note: Grapefruit can interact with numerous medications by affecting how they're metabolized. Anyone taking prescription medications should consult their healthcare provider before regularly consuming grapefruit.

Practical Application: Eat whole citrus fruits rather than juice to retain fiber. The white pith beneath the peel contains additional beneficial compounds and fiber, so don't remove it completely.

Other Notable Fiber-Rich Fruits

Kiwis: Provide approximately 5 grams of fiber per two medium fruits, with particularly beneficial effects on digestion and blood sugar control.

Passion Fruit: Contains about 2 grams of fiber per fruit, with seeds providing much of the fiber content.

Figs (fresh, not dried): Offer approximately 1.5 grams of fiber per medium fig, though dried versions concentrate both fiber and sugar, requiring portion awareness.

Top High-Fiber Green Vegetables for Diabetes and Weight Loss

Green vegetables represent the nutritional foundation of any diet focused on blood sugar control and weight management. They combine high fiber content with minimal calories and carbohydrates, making them virtually unlimited foods even for diabetics.

Leafy Greens: The Fiber-Dense Nutrient Powerhouses

Spinach provides approximately 4 grams of fiber per cooked cup (about 1 gram per raw cup) with only 41 calories when cooked. It's extraordinarily nutrient-dense, providing vitamins A, C, K, folate, iron, and magnesium—many of which are depleted in diabetics.

Kale delivers approximately 2.6 grams of fiber per cooked cup with exceptional antioxidant content. Its glucosinolates and flavonoids provide anti-inflammatory and potentially anti-diabetic effects.

Collard Greens offer about 5.3 grams of fiber per cooked cup, making them among the highest-fiber leafy greens. They're particularly rich in vitamin K and calcium.

Swiss Chard provides approximately 3.7 grams of fiber per cooked cup alongside betalains—unique antioxidants with anti-inflammatory properties beneficial for metabolic health.

Practical Application: Leafy greens can be consumed raw in salads, sautéed with garlic and olive oil, blended into smoothies, or added to soups and stews. Their minimal caloric impact allows generous portions that increase meal volume and satiety without significantly affecting blood sugar or calorie intake.

Broccoli: The Cruciferous Fiber Star

Broccoli ranks among the most studied vegetables for metabolic health, providing approximately 5 grams of fiber per cooked cup with only 55 calories. It contains sulforaphane, a compound extensively researched for its potential to improve insulin sensitivity and glucose metabolism.

A study in Science Translational Medicine found that concentrated broccoli sprout extract improved glycemic control in obese patients with type 2 diabetes, suggesting powerful metabolic benefits from cruciferous vegetables.

Beyond blood sugar control, broccoli's fiber and low energy density make it exceptional for weight loss. Research consistently shows that increased cruciferous vegetable consumption is associated with lower body weight and reduced diabetes risk.

Practical Application: Lightly steaming preserves more nutrients and fiber than boiling. Roasting broccoli caramelizes its natural sugars, creating appealing flavor without added calories. Raw broccoli florets make excellent crudité for fiber-rich snacking.

Brussels Sprouts: Miniature Fiber Packages

These compact cruciferous vegetables deliver approximately 4 grams of fiber per cooked cup with only 56 calories. Like broccoli, they contain glucosinolates that support detoxification and may improve insulin sensitivity.

Brussels sprouts' combination of fiber, protein (about 4 grams per cup), and minimal carbohydrates creates ideal macronutrient ratios for blood sugar control and satiety.

Practical Application: Roasting Brussels sprouts at high temperature (around 400°F) creates crispy, caramelized exteriors that transform skeptics into enthusiasts. Slicing them thin for raw salads provides exceptional crunch and fiber.

Green Beans: The Versatile Fiber Source

Green beans provide approximately 4 grams of fiber per cooked cup with only 44 calories and minimal blood sugar impact. They're particularly rich in vitamins C and K and contain beneficial plant compounds including carotenoids.

Their mild flavor and versatility make them accessible to even picky eaters, increasing adherence to high-fiber eating patterns.

Practical Application: Steam, sauté, or roast green beans. Adding almonds creates a classic combination that increases both fiber and healthy fat content, further stabilizing blood sugar response.

Asparagus: The Prebiotic Fiber Champion

Asparagus delivers approximately 2.8 grams of fiber per cooked cup, with particularly high inulin content—a prebiotic fiber that feeds beneficial gut bacteria. Emerging research suggests that gut microbiome health significantly influences both blood sugar control and weight management.

Asparagus is also naturally diuretic and low in calories (only 27 per cooked cup), supporting water balance and weight loss efforts.

Practical Application: Roast asparagus with olive oil and lemon for simple preparation that preserves nutrients. The thick stalks contain more fiber than thin varieties.

Artichokes: The Fiber Superstars

While not technically a leafy green, artichokes deserve mention as extraordinary fiber sources. One medium artichoke provides approximately 7 grams of fiber—among the highest of any vegetable—with only 60 calories.

Artichokes contain cynarin and silymarin, compounds that support liver health and may improve cholesterol levels often elevated in diabetics.

Practical Application: Fresh artichokes require preparation time but deliver exceptional fiber. Frozen or canned artichoke hearts (packed in water, not oil) offer convenience while retaining most nutritional benefits.

Okra: The Mucilaginous Fiber Source

Okra provides approximately 3 grams of fiber per cooked cup, with unique mucilaginous soluble fiber that's particularly effective for blood sugar control. Studies have specifically examined okra's anti-diabetic properties, with research suggesting it may reduce glucose absorption and improve insulin sensitivity.

Practical Application: Okra's texture can be off-putting when overcooked. Quick sautéing, roasting at high heat, or using it in stews minimizes sliminess while preserving fiber and nutrients.

Peas: The Protein-Fiber Combination

Green peas deliver approximately 8.8 grams of fiber per cooked cup alongside 8 grams of protein—an exceptional macronutrient profile for blood sugar control and satiety. Though technically legumes, their common classification as vegetables warrants inclusion.

The combination of protein and fiber creates remarkable fullness, with studies showing pea consumption significantly reduces subsequent food intake.

Practical Application: Frozen peas retain nutritional value and offer year-round convenience. Add them to grain dishes, salads, or eat as a simple side vegetable.

Strategic Implementation for Maximum Benefits

Understanding which foods are high in fiber is only the beginning. Strategic implementation maximizes their blood sugar-regulating and weight loss benefits:

Start Meals with Fiber

Research shows that consuming vegetables at the beginning of meals, before protein and carbohydrates, significantly reduces post-meal blood sugar spikes. This "food sequencing" approach optimizes fiber's glucose-buffering effects.

Combine Fiber with Protein and Healthy Fats

While fiber alone provides benefits, combining high-fiber foods with protein and healthy fats creates optimal satiety and blood sugar stability. For example, apples with almond butter, vegetables with olive oil, or berries with Greek yogurt.

Increase Gradually

Rapidly increasing fiber intake can cause digestive discomfort including gas, bloating, and cramping. Increase fiber gradually over 2-3 weeks, allowing your digestive system and gut microbiome to adapt.

Hydrate Adequately

Fiber absorbs water, so adequate hydration is essential for optimal function. Aim for at least 8-10 glasses of water daily when consuming high-fiber diets.

Choose Whole Over Processed

Whole fruits and vegetables provide vastly more fiber than juices, purees, or refined alternatives. An orange contains 3 grams of fiber; orange juice contains essentially none.

Supporting Your High-Fiber Journey

While whole foods should form the foundation of your fiber intake, some individuals benefit from additional support, particularly when increasing fiber intake or managing digestive health during dietary transitions.

FAQ About Top High Fiber Foods for Diabetes & Weight Loss: Doctor Recommended List

The general recommendation for adults is 25-38 grams of fiber daily, but for diabetes management and weight loss, many healthcare providers recommend targeting the higher end of this range or even 40-50 grams daily. Research suggests that each additional 10 grams of daily fiber correlates with measurable improvements in blood sugar control and weight loss outcomes. However, it's crucial to increase fiber gradually rather than making dramatic overnight changes, as rapid increases can cause digestive discomfort including bloating, gas, and cramping. Start by adding 5 grams of additional fiber every few days, allowing your digestive system to adapt. Track your fiber intake for a few days to establish your baseline, then systematically increase by incorporating more high-fiber fruits and vegetables at each meal. Most people fall short of recommendations, consuming only 15 grams daily, so even modest increases provide significant benefits. For diabetes specifically, studies show that consuming at least 30 grams of fiber daily significantly improves glycemic control and reduces HbA1c levels. Consult with your healthcare provider or registered dietitian for personalized recommendations based on your specific health status and goals.

This common concern causes many diabetics to unnecessarily eliminate fruit from their diets, missing out on valuable nutrients and fiber. The truth is more nuanced: whole fruits with high fiber content, consumed in appropriate portions, generally have minimal impact on blood sugar when incorporated into a balanced eating pattern. The fiber in whole fruit slows the absorption of natural sugars, preventing the rapid spikes associated with fruit juice or refined sugars. Research published in the British Medical Journal found that greater whole fruit consumption was associated with significantly lower risk of type 2 diabetes, while fruit juice consumption increased risk—highlighting the critical importance of fiber. The key is choosing high-fiber, low-glycemic fruits like berries, apples with skin, pears, and citrus fruits, and consuming them with protein or healthy fats to further stabilize blood sugar response. Portion awareness matters: a serving of fruit is typically one medium piece, one cup of berries, or half cup of diced fruit. Spreading fruit consumption throughout the day rather than eating multiple servings at once helps maintain stable blood sugar. Monitor your individual response using a glucose meter to determine which fruits and portions work best for you.

Non-starchy vegetables, particularly the green vegetables highlighted in this guide, can be consumed in very generous quantities without significantly impacting calorie intake or weight loss progress. Their combination of high fiber, high water content, and minimal calories creates exceptional satiety relative to their caloric contribution. For example, you could eat an entire pound of broccoli for only 150 calories while consuming 14 grams of fiber—an amount of fiber and food volume that would create substantial fullness. Many successful weight loss approaches specifically recommend filling half your plate with non-starchy vegetables at each meal, effectively reducing calorie density while increasing nutrient intake and satiety. However, preparation methods matter significantly: vegetables sautéed in excessive oil, covered in cheese sauce, or fried add substantial calories that can hinder weight loss. Similarly, starchy vegetables like potatoes, corn, and winter squash, while nutritious, contain more calories and carbohydrates requiring portion awareness. For the leafy greens and cruciferous vegetables featured in this guide, practical limits are typically determined by fullness and digestive tolerance rather than caloric concerns. The digestive system can only process so much fiber before feeling uncomfortably full, creating a natural upper limit on vegetable consumption.

While fiber supplements like psyllium husk, methylcellulose, or inulin can help increase fiber intake and provide certain benefits, they should complement rather than replace whole food fiber sources. Whole high-fiber fruits and vegetables provide not just fiber but also vitamins, minerals, antioxidants, phytonutrients, and water—a nutritional package that supplements cannot replicate. Research consistently shows that fiber from whole foods provides superior metabolic benefits compared to isolated fiber supplements. However, supplements can be valuable tools when strategically used: they can help bridge gaps on days when whole food fiber intake falls short, provide concentrated doses of specific fiber types like soluble fiber for cholesterol management, ease the transition when increasing dietary fiber by providing controlled amounts, or support individuals with limited appetites who struggle to consume sufficient vegetable volume. If you choose to supplement, select products containing mixed fiber types (both soluble and insoluble), start with small doses and increase gradually, take with adequate water, and space fiber supplements away from medications as fiber can interfere with absorption. The optimal approach combines abundant whole food fiber sources with targeted supplementation when needed, ensuring you receive both the fiber and the complete nutritional package that whole plant foods provide.

Digestive discomfort when increasing fiber intake is common but usually temporary. Your gut microbiome needs time to adapt to processing higher fiber loads, and the bacteria that ferment fiber produce gas as a byproduct. Several strategies minimize discomfort: increase fiber gradually over several weeks rather than making dramatic overnight changes, ensure adequate hydration (at least 8-10 glasses of water daily) as fiber requires water to move smoothly through the digestive tract, cook vegetables rather than eating them raw initially, as cooking breaks down some fiber structures making them easier to digest, chew food thoroughly to aid digestive processing, try digestive enzymes or probiotics to support gut function during the transition period, identify specific triggers through elimination and reintroduction, and consider that certain high-fiber foods are more gas-producing than others—cruciferous vegetables, beans, and certain raw vegetables commonly cause more gas. If digestive problems persist beyond 3-4 weeks of gradual fiber increases, consult a healthcare provider to rule out conditions like irritable bowel syndrome, small intestinal bacterial overgrowth (SIBO), or food intolerances that may require different dietary approaches. For most people, initial discomfort resolves as the gut adapts, and the long-term benefits of high-fiber eating far outweigh temporary adjustment challenges.

This question often creates unnecessary barriers to eating more vegetables. The reality is that frozen vegetables are often equally or more nutritious than fresh options, particularly when "fresh" vegetables have been transported long distances and stored for extended periods before consumption. Vegetables destined for freezing are typically processed within hours of harvest, locking in nutrients at peak ripeness. Research comparing nutrient content finds minimal differences between fresh and frozen for most vitamins, minerals, and fiber. Frozen vegetables offer significant practical advantages including longer storage life reducing food waste, year-round availability regardless of season, pre-washed and pre-cut convenience reducing preparation barriers, and often lower cost. For canned vegetables, nutrient retention is generally good for most compounds, though water-soluble vitamins like vitamin C may be reduced. The primary concerns with canned vegetables are added sodium and BPA in can linings—issues addressed by choosing low-sodium or no-salt-added varieties and BPA-free packaging when available. Rinse canned vegetables before use to reduce sodium content by up to 40%. The most important factor for diabetes and weight loss is eating more vegetables regardless of form. If frozen or canned options make you more likely to actually consume vegetables regularly, they're superior to fresh vegetables that spoil unused in your refrigerator. The fiber content—the focus for blood sugar and weight management—remains essentially identical across fresh, frozen, and canned forms.

Time constraints are among the most common barriers to healthy eating, but strategic approaches make high-fiber eating compatible with busy lifestyles. Meal planning and batch preparation allow you to prepare multiple servings of high-fiber foods when you have time: wash and chop vegetables on weekends for easy weekday use, cook large batches of vegetables to reheat throughout the week, portion fresh fruit into grab-and-go containers, keep frozen vegetables stocked for quick additions to any meal (they require no preparation and cook in minutes), use pre-washed salad greens and pre-cut vegetables when convenience justifies the cost, incorporate high-fiber foods into quick meals like adding berries to yogurt or oatmeal, tossing frozen vegetables into pasta, soups, or grain bowls, keeping apples and other whole fruits visible and accessible for instant snacks, and blending spinach or kale into smoothies for effortless vegetable servings. Consider that many high-fiber vegetables like broccoli, green beans, and Brussels sprouts cook in 5-10 minutes—less time than many people spend on drive-through lines. Building habits around convenient high-fiber options makes healthy eating automatic rather than requiring continuous conscious effort. Start with just one or two strategies and build from there rather than attempting complete dietary transformation overnight.

When increasing dietary fiber, particularly if you're starting from a low baseline, your digestive system may benefit from additional support during the transition. Quality digestive supplements can provide enzymes to help break down fiber, probiotics to support beneficial bacteria that ferment fiber, and targeted nutrients that support intestinal health and optimal digestion. Look for products that contain comprehensive digestive enzyme blends including cellulase (breaks down plant fiber), diverse probiotic strains that support gut microbiome diversity, prebiotic fibers that feed beneficial bacteria without causing excessive gas, ingredients like ginger or peppermint that ease digestive discomfort, and clear labeling about potency and suggested usage. Avoid products with unnecessary fillers, artificial ingredients, or proprietary blends that don't disclose specific quantities.
