When hunger strikes, your first instinct might be to reach for a snack. But what if you could satisfy your appetite—without chewing a thing? The truth is, certain drinks are packed with nutrients, fiber, volume, and protein that not only soothe your stomach but also help you feel fuller, longer. Whether you’re trying to manage weight, reduce unnecessary snacking, or simply stay energized between meals, understanding what can I drink to fill me up is key to smarter, more sustainable eating habits.
This comprehensive guide uncovers the most effective hunger-curbing beverages, backed by science and nutrition expertise. From protein-rich shakes to fiber-filled smoothies and strategically prepared broth, we’ll explore drinks that go beyond hydration and serve as real, satisfying meal components.
The Science Behind Feeling Full: How Drinks Influence Satiety
Feeling full, or satiety, is a complex physiological process involving your stomach, hormones, and brain. It’s not just about food volume—it’s about how your body processes nutrients and signals that the need for energy has been met.
Several factors determine whether a drink will keep you full:
- Volume and stomach distension: Liquid volume stretches the stomach, which triggers fullness signals to the brain.
- Macronutrient composition: Protein, fiber, and healthy fats slow digestion and prolong satiety.
- Energy density: Low-calorie, high-volume drinks can sometimes be more filling than calorie-dense, low-volume options.
- Hydration: Dehydration can masquerade as hunger. Staying hydrated prevents false hunger pangs.
While most beverages pass through the digestive system quickly, certain drinks—especially those rich in protein, fiber, and strategic volume—can deliver long-lasting satiety. The trick is choosing drinks that act like food in terms of impact.
Why Liquid Satiety Matters for Health and Weight Management
Liquid calories are often overlooked when monitoring portion sizes. However, not all liquid calories are born equal. Sugary sodas and fruit juices spike blood sugar and offer empty calories, leading to hunger shortly after consumption. Conversely, nutrient-dense drinks can stabilize blood sugar, maintain energy, and reduce cravings.
According to a study published in the Journal of the American College of Nutrition, beverages with higher protein content significantly reduce hunger and subsequent food intake compared to carbohydrate-heavy or low-protein drinks. This makes protein-rich drinks especially effective for people on weight loss journeys or those seeking more balanced eating patterns.
Top Drinks That Fill You Up (And Why They Work)
Below are some of the most effective drinks scientifically proven to promote fullness. Each option combines volume, nutrition, and practicality, making them ideal for curbing appetite without overeating.
1. Protein Shakes and Smoothies
Protein is the most satiating macronutrient. High-protein beverages keep you full longer by reducing levels of ghrelin—the “hunger hormone”—and increasing levels of peptide YY, which signals fullness.
- Whey protein shakes: Fast-digesting and rich in essential amino acids, whey protein is excellent post-workout or between meals.
- Casein protein shakes: Slower to digest than whey, casein creates a prolonged feeling of fullness—ideal before bedtime.
- Plant-based protein smoothies: Made with pea, hemp, or brown rice protein, these offer great satiety for vegans and those avoiding dairy.
A study from the Journal of Nutrition revealed that participants who consumed a high-protein shake as a mid-morning snack ate 12% fewer calories at lunch compared to those who had a carbohydrate-based drink.
Tips for Building a Filling Protein Shake
- Use at least 20–30 grams of protein per serving.
- Add fiber: Blend in chia seeds, flaxseeds, or half a banana.
- Include healthy fats: A tablespoon of almond butter or avocado increases satiety.
- Use water, unsweetened almond milk, or low-fat milk as a base to control added sugars.
- Add ice for extra volume—cold drinks tend to stay in the stomach longer.
2. Vegetable-Based Smoothies and Juices
While most juices strip out fiber, blending whole vegetables into a smoothie retains bulk and nutrients, adding to fullness. Low in calories but high in volume, vegetable smoothies stretch your stomach and deliver essential micronutrients.
Best vegetables for filling smoothies:
– Cucumber (high water content)
– Spinach and kale (high fiber)
– Cooked cauliflower or zucchini (low-calorie volume boosters)
– Celery (negligible calories, lots of volume)
Blend these with a base of water or unsweetened vegetable broth, a touch of lemon juice, and a small amount of low-sugar fruit like green apple or lime for taste. Adding a scoop of protein powder or Greek yogurt transforms this into a satisfying mini-meal.
3. Bone Broth and Vegetable Broth
Warm, savory broths have long been used to prepare the stomach for meals or serve as low-calorie meal replacements during fasting. Thanks to their high water content and modest sodium and collagen, broths can induce fullness without adding substantial calories.
Bone broth is especially beneficial due to its:
– Collagen content: Helps support gut health and may reduce inflammation.
– Sodium levels: Encourage fluid retention in the stomach, enhancing fullness sensation.
– Umami flavor: This savory taste increases satisfaction and can reduce hunger cravings.
A 2018 study in Appetite found that participants who consumed a broth-based soup before a meal ate 20% fewer calories than those who didn’t. The sensation of warmth and volume plays a powerful role in curbing appetite.
How to Make Broth More Satiating
- Add cooked vegetables like carrots, onions, or mushrooms.
- Stir in lentils or quinoa for protein and fiber.
- Include a spoonful of tahini or olive oil for healthy fats.
- Season with herbs like thyme or rosemary to enhance flavor without extra calories.
4. High-Fiber Drinks: Chia Seed Water and Flaxseed Infusions
Fiber is a critical component of satiety. While traditionally associated with solid foods, certain drinks can deliver a fiber punch.
Chia seed water has gained popularity not just as a trendy drink but as a proven hunger suppressant. When soaked in liquid, chia seeds absorb up to 10–12 times their weight, forming a gel-like consistency that slows digestion and prolongs fullness.
Here’s how a 2-tablespoon serving of chia seeds boosts satiety:
– 10 grams of fiber
– 4 grams of protein
– Omega-3 fatty acids
– Gel-forming capacity that controls blood sugar spikes
Similarly, flaxseed infused in water or smoothies offers soluble fiber, which reduces appetite and improves gut health.
How to Prepare Chia Seed Water
- Mix 2 tablespoons of chia seeds with 16 oz of water.
- Add lemon juice and a pinch of cinnamon for flavor.
- Stir well and let sit for 15–20 minutes until gel forms.
- Stir again before drinking to prevent clumping.
This drink is especially effective when consumed 30 minutes before a meal.
5. Milk (Especially Plant-Based with Added Protein)
Despite being a liquid, milk is surprisingly filling due to its natural blend of protein, fat, and carbohydrates. Cow’s milk contains about 8 grams of protein per cup, while fortified almond and soy milks can match or exceed this—if carefully selected.
A 2020 study in *Nutrients* compared various milk types and concluded that both dairy and soy milk were significantly more satiating than sugary beverages or water alone. The combination of casein and whey in dairy, or complete plant proteins in soy, mimics the fullness effect of solid meals.
Make the Most of Milk as a Filler
– Choose unsweetened, high-protein versions.
– Warm milk before bed: The combination of tryptophan and warmth may curb late-night cravings.
– Add a spoon of nut butter for lasting satisfaction.
– Blend into smoothies or oatmeal to enhance volume and nutrient density.
6. Meal Replacement Shakes
Meal-replacement shakes are formulated to deliver balanced nutrition in a convenient liquid form. Unlike simple protein shakes, they contain a mix of macronutrients, fiber, and often added vitamins and minerals.
Top benefits:
– Controlled portion sizes prevent overeating.
– Often include 20+ grams of protein and 5+ grams of fiber.
– Some are low-glycemic, helping stabilize energy levels.
Brands like Huel, Soylent, and OWYN offer complete nutrition in a shake. When used in place of a high-calorie or low-nutrient meal, they can support weight management and reduce overall calorie intake.
Things to Watch For:
– Avoid shakes with more than 10 grams of added sugar.
– Aim for at least 20 grams of protein and 5 grams of fiber.
– Check the ingredient list: Simpler is usually better.
Drinks That Seem Filling But Actually Aren’t
Just because a drink is calorie-dense doesn’t mean it’s satiating. Some liquids trigger insulin spikes and leave you hungrier than before.
1. Fruit Juices (Even 100% Natural)
Despite being “healthy,” fruit juices lack the fiber found in whole fruits. Without fiber, fructose is absorbed rapidly, leading to blood sugar fluctuations and increased hunger. A glass of orange juice may have 110 calories and no protein, leaving you unsatisfied minutes later.
2. Sugary Coffee Drinks
A caramel macchiato or frappuccino may have 300–500 calories, but those come mostly from sugar and cream. The absence of fiber and adequate protein means you’ll crash and crave solid food soon after.
Tip: Opt for black coffee with a splash of milk or a protein-added latte to leverage caffeine’s mild appetite-suppressant effects without the sugar spike.
3. Soda and Energy Drinks
Carbonated beverages and energy drinks deliver empty calories. Studies show that liquid sugar doesn’t register the same fullness signals as solid food, causing people to consume more total calories throughout the day.
How to Choose the Right Drink to Fill You Up
Not every fullness-inducing drink works for every person or situation. Consider your goals—weight loss, muscle gain, digestion support—when selecting your drink.
Consider These Factors
– Meal timing: Before a meal? Broth or chia water. Between meals? Protein shake. Late night? Warm milk.
– Lifestyle: On-the-go? Choose ready-to-drink shakes or portable smoothies.
– Dietary needs: Vegan? Prioritize plant-based protein. Low-FODMAP? Choose lactose-free or broth options.
– Health conditions: Kidney disease or diabetes? Consult your doctor before increasing protein or fiber intake.
Nutrition Comparison of Fill-Up Drinks
| Drink | Protein (g) | Fiber (g) | Calories (per 8 oz or serving) | Satiety Rating (1–10) |
|---|---|---|---|---|
| Whey Protein Shake (1 serving) | 25 | 2–5 | 150–200 | 9 |
| Vegetable Smoothie (homemade) | 4 | 6 | 100 | 7 |
| Bone Broth (1 cup) | 5–10 | 0 | 60–90 | 6 |
| Chia Seed Water (2 tbsp in 16 oz) | 4 | 10 | 137 | 8 |
| Unsweetened Soy Milk (1 cup) | 7–9 | 2–4 | 80–100 | 7 |
| Meal Replacement Shake (e.g., Huel) | 20–30 | 7–10 | 400 | 10 |
This chart highlights how combining protein and fiber dramatically increases satiety. Drinks rated above 8 are excellent for replacing or supplementing solid meals.
Maximizing Satiety: Practical Strategies
Knowing what to drink is half the battle. How and when you consume these drinks makes all the difference.
1. Slow Down Your Drinking
Sipping a smoothie over 15–20 minutes signals fullness more effectively than gulping it down. The brain takes about 20 minutes to register satiety, so pacing allows your body time to respond.
2. Serve Drinks Cold or Warm, Based on Preference
– Cold drinks: Take longer to empty from the stomach, extending satiety.
– Warm drinks: Trigger comfort signals—ideal for evening use or when cravings are emotional.
3. Combine Drinks with Mindful Eating Habits
Even the most filling drink won’t help if consumed while distracted. Practice mindful drinking:
– Sit at a table.
– Eliminate screens.
– Focus on flavor and fullness cues.
4. Time Your Sips Strategically
– 30 minutes before meals: Chia water or broth to reduce overeating.
– Mid-morning or mid-afternoon: Protein shake as a snack.
– Post-exercise: Recovery shake with protein and carbs.
– Before bed: Casein protein or warm milk to prevent nighttime hunger.

What types of drinks can help me feel full and reduce hunger naturally?
Several beverages can promote satiety and help curb hunger by stimulating the feeling of fullness in your stomach, stabilizing blood sugar levels, and supporting digestive health. Drinks high in protein, fiber, and healthy fats are particularly effective. For example, smoothies made with Greek yogurt, chia seeds, or nut butter can deliver lasting fullness. Water-rich beverages like vegetable broth or soups also increase stomach volume without adding many calories, helping you feel satisfied.
Other satisfying options include milk, especially plant-based varieties fortified with protein and fiber like soy or oat milk, and protein shakes tailored for meal replacement. Herbal teas that contain ingredients like glucomannan or fenugreek may also aid appetite control. By choosing nutrient-dense drinks over sugary, empty-calorie beverages, you support both hunger management and overall health. Timing matters too—drinking these satiating beverages before meals can reduce overall calorie intake.
Can drinking water really help me feel less hungry?
Yes, drinking water can significantly reduce feelings of hunger, especially when consumed before meals. Studies have shown that drinking a glass or two of water shortly before eating can decrease appetite and lead to reduced calorie consumption during the meal. This occurs because water fills the stomach, triggering stretch receptors that signal fullness to the brain. It’s particularly helpful for people who sometimes confuse thirst with hunger, a common occurrence.
Additionally, staying well-hydrated supports proper metabolic function and digestion, which aids in more accurate hunger signaling. Drinking water throughout the day helps maintain this balance and may prevent unnecessary snacking. For even greater satiety, consider drinking warm water with lemon or infused with fiber-rich ingredients like cucumber or ginger. These variations can enhance the feeling of fullness and support digestive health without adding significant calories.
Are protein shakes effective for satisfying hunger between meals?
Protein shakes are highly effective at curbing hunger due to protein’s strong satiating effect. Protein slows gastric emptying and increases the levels of hormones like GLP-1 and peptide YY, which contribute to feelings of fullness. A well-formulated protein shake—especially one made with whey, casein, or plant-based proteins like pea or soy—can provide 15 to 30 grams of protein per serving, making it a powerful tool for appetite control.
Moreover, protein shakes can be customized to include other satiety-promoting ingredients such as oats, nut butter, flaxseed, or Greek yogurt. These additions increase fiber and healthy fat content, extending the feeling of fullness. However, it’s important to choose shakes with minimal added sugars and artificial ingredients. When used as a snack or light meal replacement, protein shakes can support weight management and overall nutritional balance when incorporated appropriately into daily eating patterns.
How do fiber-rich drinks like smoothies help with hunger?
Smoothies that include whole fruits, vegetables, and high-fiber add-ins such as chia seeds, flaxseeds, or oats are excellent for maintaining fullness. The soluble fiber in these ingredients absorbs water and forms a gel-like substance in the gut, slowing digestion and prolonging satiety. Unlike juice, which removes most of the fiber, whole-food-based smoothies retain both soluble and insoluble fiber, better supporting blood sugar regulation and digestion.
Drinking a fiber-rich smoothie can lead to a gradual release of energy, preventing spikes and crashes in blood sugar that often trigger hunger. Including protein and healthy fats—such as nut butter or avocado—further enhances this effect by adding macronutrient balance. For maximum impact, use whole, unprocessed ingredients and avoid added sugars. A well-rounded high-fiber drink can serve as a satisfying meal replacement or a hearty snack that tides you over until your next meal.
Is bone broth a good drink for reducing hunger and supporting fullness?
Bone broth has gained popularity as a satisfying, low-calorie drink that provides essential nutrients and a sense of fullness. It’s rich in collagen, gelatin, and amino acids like glycine and proline, which can support gut health and reduce inflammation. The warmth and volume of a cup of broth can activate stomach stretch receptors, signaling to the brain that you’ve consumed food, even if calorie content is modest.
Additionally, bone broth contains moderate amounts of protein, which enhances satiety. Sipping bone broth before meals may reduce overall food intake by pre-filling the stomach and stabilizing appetite. Its savory flavor also helps satisfy cravings for salty or umami-rich foods, making it a strategic choice for those trying to reduce snacking. To get the most benefit, choose or prepare bone broth without excessive sodium and pair it with fiber-rich foods when using it as part of a meal.
Can herbal teas help suppress appetite and keep me full?
Certain herbal teas may help reduce appetite and promote feelings of fullness, primarily through psychological and digestive effects. Teas such as green tea, peppermint, ginger, and dandelion root stimulate digestion and can create a sense of warmth and satisfaction that mimics fullness. Green tea contains catechins and a small amount of caffeine, both of which may slightly boost metabolism and reduce feelings of hunger.
Some herbal blends include natural appetite suppressants like hoodia or forskolin, though scientific support for these is limited. More reliably, fiber-enhanced teas containing ingredients like glucomannan expand in the stomach when consumed with water, increasing satiety. Drinking herbal tea slowly allows time for fullness signals to reach the brain, which can prevent overeating. While not a meal replacement, herbal teas can be a valuable part of a strategy to manage hunger and support hydration.
What should I avoid when choosing drinks to manage hunger?
When selecting beverages to help control hunger, it’s crucial to avoid drinks high in added sugars, artificial sweeteners, and empty calories. Sugary sodas, fruit juices, and flavored coffee drinks can spike blood sugar levels, leading to rapid crashes that increase hunger and cravings shortly after consumption. Even drinks labeled as “diet” or “low-calorie” may contain artificial sweeteners that can disrupt appetite regulation for some individuals.
Furthermore, highly caffeinated drinks without nutritional content, such as energy drinks or black coffee on an empty stomach, might suppress appetite temporarily but can lead to jitteriness, dehydration, and rebound hunger later. Alcohol is another category to limit, as it provides empty calories and can impair judgment, potentially leading to overeating. Prioritizing whole, minimally processed beverages with protein, fiber, or healthy fats ensures longer-lasting fullness and better alignment with your health goals.
