If you feel like your energy is dragging, your weight won’t budge, or your workouts aren’t paying off, your metabolism might be part of the problem. The foods you eat play a major role in how efficiently your body burns calories and converts fuel into energy. Some ingredients work for you—helping to boost fat burning, improve digestion, and keep you energized. Others quietly slow things down. In this science-backed guide, we’ll reveal 10 foods that may be stalling your metabolism and 10 powerhouse picks that can help rev it up, naturally and effectively.
1. BUST: Sugary Beverages
Sipping on sodas, sweet teas, or sugary energy drinks might feel like a quick energy boost, but they’re a hidden threat to your metabolism. These drinks are loaded with simple sugars that cause blood sugar spikes, leading to insulin resistance over time. They also lack any nutritional value, offering no fiber or protein to slow digestion or feed your gut microbiome. Instead of fueling your body, sugary beverages can promote fat storage and sluggish metabolic function. Replacing them with water, herbal tea, or naturally flavored seltzers is a simple change with big metabolic rewards.
2. BUST: Pastries
Delicious as they may be, pastries are one of the worst offenders when it comes to slowing down your metabolism. These baked treats are often made with refined flour, trans fats, and added sugars—a combination that digests quickly, spikes your blood sugar, and encourages fat storage.
They provide very little protein or fiber, leaving you hungry again soon after. This constant cycle of sugar highs and crashes can make your metabolism less efficient over time. Swapping pastries for whole-grain snacks with healthy fats and protein can help stabilize energy and support a healthier metabolic rate.
3. BUST: Fried Foods
Golden and crispy on the outside, fried foods hide a dark side when it comes to metabolism. Cooking at high temperatures in unhealthy oils creates trans fats and inflammatory compounds that disrupt your body’s ability to burn calories efficiently. Regular consumption can slow digestion, increase fat accumulation, and lead to insulin resistance. Fried foods are also often calorie-dense and low in nutrients, leaving your metabolism sluggish and overworked. Choosing baked, grilled, or air-fried alternatives can lighten the metabolic load while still delivering satisfying flavor and texture.
4. BUST: Processed Meats
From bacon to hot dogs, processed meats are filled with preservatives, sodium, and saturated fats that don’t do your metabolism any favors. These ingredients can trigger inflammation, disrupt gut health, and interfere with your body’s natural fat-burning processes.
They’re also often paired with low-fiber sides, creating a combo that slows digestion and energy output. Long-term, regular intake of processed meats may contribute to metabolic syndrome. If you’re aiming for a faster metabolism and better health, consider replacing processed options with lean, unprocessed proteins like chicken, fish, or plant-based sources.
5. BUST: Alcohol
That nightly glass of wine or weekend cocktail may seem harmless, but alcohol can interfere with your metabolism in several ways. When consumed, your body prioritizes metabolizing alcohol over other nutrients, temporarily halting fat burning. Alcohol also affects sleep quality, hormones, and hydration—all factors tied closely to metabolic health. Over time, frequent drinking may slow your metabolic rate and promote fat storage, particularly around the midsection. Moderating your intake or opting for alcohol-free alternatives can help restore balance and keep your metabolism functioning more efficiently.
6. BUST: Granola Bars (with added sugars)
They may be marketed as health snacks, but many store-bought granola bars are essentially candy bars in disguise. Packed with added sugars, refined grains, and artificial ingredients, these bars can spike your blood sugar and send your metabolism into a crash.
While they’re often labeled as “high energy,” that energy is short-lived and followed by sluggishness. The lack of fiber and protein in many varieties also means your body burns fewer calories processing them. If you’re grabbing a granola bar, choose one with whole ingredients, minimal sugar, and balanced macronutrients to support—not sabotage—your metabolism.
7. Flavored Yogurt
Don’t let the creamy texture and fruity flavor fool you—flavored yogurts are often loaded with hidden sugars that can work against your metabolic health. Many single-serving containers contain more sugar than a doughnut, which can disrupt insulin sensitivity and promote fat storage. Although yogurt itself can be a metabolism-boosting food when rich in protein and probiotics, the added sweeteners in flavored varieties negate these benefits. To keep your metabolism humming, opt for plain Greek yogurt and sweeten it naturally with fresh fruit, cinnamon, or a drizzle of honey.
8. BUST: Fruit Juices
While they sound wholesome, fruit juices are stripped of the fiber that whole fruits provide, leaving behind mostly sugar. That quick hit of fructose can overwhelm the liver, disrupt blood sugar levels, and slow metabolic function when consumed frequently.
Even 100% juice options can cause energy dips and poor nutrient absorption due to their lack of fiber and protein. Whole fruits are a far better option—they digest slower, keep you full longer, and provide antioxidants and fiber that support metabolic health. When in doubt, eat your fruit, don’t drink it.
9. BUST: White Bread
Soft and fluffy, white bread may be easy to digest—but that’s exactly why it’s a metabolism offender. Made from refined flour, it breaks down quickly in the body, leading to rapid blood sugar spikes and crashes. This promotes fat storage, reduces energy efficiency, and leaves you craving more soon after.
White bread also lacks the fiber needed to feed your gut bacteria, which play a critical role in metabolic function. Choosing whole-grain alternatives rich in fiber and nutrients can help steady your blood sugar and keep your metabolism firing on all cylinders.
10. BUST: Dairy Alternatives with Additives
Not all dairy-free options are created equal. Many plant-based milks and yogurts contain thickeners, sweeteners, and emulsifiers that may disrupt your gut microbiome and hinder metabolism. Some additives, like carrageenan or artificial flavors, can trigger inflammation or digestive discomfort, slowing your system’s efficiency. Flavored versions often include added sugars that spike insulin and reduce metabolic stability. For a gut- and metabolism-friendly option, look for unsweetened versions with short ingredient lists and added protein. Simpler is better when it comes to dairy alternatives that support rather than sabotage your body’s natural rhythm.
11. BOOST: Lean Meats
Lean meats like chicken, turkey, and lean beef don’t just fuel your muscles—they also help fire up your metabolism. That’s thanks to the thermic effect of food (TEF), which means your body uses more energy digesting protein than it does fats or carbs.
Protein helps maintain muscle mass, which is key to keeping your resting metabolic rate high. Including lean meats in your meals not only satisfies hunger but also supports calorie burning throughout the day. Stick with grilled or baked options to maximize the benefits and avoid added fats that could slow you down.
12. BOOST: Chili Peppers
Adding some spice to your meals could help heat up your metabolism too. Chili peppers contain capsaicin, a compound that slightly raises body temperature and promotes fat burning through a process called thermogenesis. This natural chemical may also help curb appetite, making you feel fuller with less food. Regularly including chili peppers in your diet—whether fresh, dried, or in sauces—could contribute to small but meaningful increases in daily calorie burn. While it’s no miracle fix, this spicy food makes a flavorful and metabolism-friendly addition to soups, stir-fries, and marinades.
13. BOOST: Green Tea
Green tea is more than a soothing drink—it’s also a metabolism booster packed with powerful compounds. Rich in catechins and a moderate dose of caffeine, green tea helps promote fat oxidation and increase energy expenditure. Drinking a few cups daily may lead to modest improvements in calorie burn, especially when paired with regular exercise. It’s a smart, low-calorie alternative to sugary drinks and supports hydration, which also aids metabolism. For best results, choose brewed green tea over sugary bottled versions, and consider it part of a healthy lifestyle rather than a quick fix.
14. BOOST: Coffee
That morning cup of coffee does more than wake you up—it can also help jumpstart your metabolism. The caffeine in coffee stimulates your central nervous system, boosting your resting metabolic rate and increasing the breakdown of fat for energy. This temporary metabolic lift may improve physical performance and enhance calorie burning throughout the day. For best results, avoid adding excess sugar or heavy cream, which can offset the benefits. Black coffee or a splash of milk is enough to keep it metabolism-friendly and energizing without extra baggage.
15. BOOST: Legumes and Pulses
Beans, lentils, and chickpeas are nutritional powerhouses that offer multiple metabolism-friendly benefits. They’re rich in protein and fiber, both of which increase the thermic effect of food and help you stay full longer. Fiber also supports gut health, which is increasingly linked to metabolic efficiency.
Their slow-digesting nature stabilizes blood sugar levels, preventing energy crashes that can lead to overeating. Swapping processed carbs for legumes in soups, salads, or grain bowls gives your meals lasting energy and supports steady calorie burning. They’re budget-friendly, versatile, and one of the smartest choices for a sustained metabolic lift.
16. BOOST: Ginger
Ginger doesn’t just soothe the stomach—it also subtly stokes your metabolism. This warming root contains compounds like gingerol and shogaol, which have been shown to increase thermogenesis, the process by which your body burns calories to produce heat. Ginger may also reduce inflammation and improve digestion, both of which can enhance metabolic efficiency over time. Whether grated fresh into meals, brewed into tea, or added to smoothies, ginger provides a spicy kick with real benefits. It’s not a magic bullet, but as part of a balanced diet, it can help keep your metabolism running smoothly.
17. BOOST: Whole Grains
Unlike their refined counterparts, whole grains like brown rice, quinoa, oats, and barley take more energy to break down—thanks to their fiber and nutrient-rich outer layers. This increased digestive effort raises the thermic effect of food, contributing to a slight metabolic boost.
Whole grains also stabilize blood sugar and support gut health, which is closely tied to metabolic function. Replacing white bread or pasta with whole grain options can enhance fullness, reduce cravings, and help your body burn calories more steadily throughout the day. They’re a simple, satisfying swap with long-lasting effects on your metabolism.
18. BOOST: Flaxseeds
Tiny but powerful, flaxseeds offer a unique blend of fiber, plant-based protein, and healthy fats that support a strong metabolism. The soluble fiber they contain helps regulate digestion and keeps you full longer, which may reduce overall calorie intake. Flaxseeds also contain lignans and omega-3s, which may reduce inflammation—an important factor in maintaining a healthy metabolic rate. Grinding them before eating helps your body absorb their nutrients more effectively. Sprinkle them into smoothies, oatmeal, or baked goods to reap the benefits. Just a tablespoon or two a day can contribute to better metabolic balance over time.
19. BOOST: Eggs
Eggs are a near-perfect metabolic food—rich in protein, vitamins, and essential fats that keep you fueled and satisfied. Their high protein content increases the thermic effect of food, requiring your body to expend more energy during digestion. This helps support muscle maintenance, which is key for sustaining a healthy metabolism. Eggs are also rich in choline, a nutrient that supports fat metabolism and liver health. Whether scrambled, boiled, or poached, they’re a versatile option for breakfast or snacks. Starting your day with eggs can help control hunger and boost calorie-burning potential for hours.
20. BOOST: Water
It may be the simplest item on this list, but water is essential for a healthy metabolism. Drinking water—especially cold—can cause a mild increase in calorie burn as your body works to bring the fluid to body temperature, a process called thermogenesis.
Staying well-hydrated also supports digestion, nutrient absorption, and energy production. Even mild dehydration can slow down your body’s ability to burn calories efficiently. Aim to drink water consistently throughout the day, especially before meals, to naturally enhance your metabolic function and curb overeating. When in doubt, drink more—it’s the ultimate metabolic ally.
