This Thermogenic Foods List includes 15 fat-burning, energy boosting foods—from chili peppers and turmeric to garlic and green tea.
If you’ve ever wondered why some foods seem to stoke your fire, leaving you feeling warm, energized, and even lighter, you’ve probably experienced the powerful mechanisms of ‘thermogenesis.’
While thermogenesis is your body’s natural way of producing heat and burning calories during digestion, certain foods—often rich in protein, fiber, spices, and bioactive compounds—can trigger it naturally.
One report notes that “Several studies have shown that obesity is associated with reduced postmeal thermogenesis”—which is exactly what we don’t want, right?
Here’s how it works:
What Is Thermogenesis?
Thermogenesis is the process by which your body generates heat, primarily by burning calories. When you eat thermogenic foods, they trigger what’s known as ‘diet-induced thermogenesis (DIT),’ or the thermic effect of food (TEF)—the energy required to digest, absorb, and metabolize nutrients.
Protein-rich foods, for instance, demand more energy to process than fats or carbs, while compounds like capsaicin in chili peppers, catechins in green tea, and caffeine in coffee stimulate the sympathetic nervous system, increasing calorie burn and fat oxidation. In addition, some thermogenic foods activate brown adipose tissue (BAT), a special type of fat that burns calories to produce heat.
Keep on reading for 15 powerhouse thermogenic foods.
Thermogenic Foods List
1. Green Tea
Green tea, and especially Matcha, is a bioactive powerhouse. Studies link it to “increased weight loss due to diet-induced thermogenesis.” The catechins in green tea, especially epigallocatechin gallate (EGCG), “fuel fat oxidation and lipolysis,” says one report.
2. Berries
Many berries, including blueberries, have thermogenic effects. One study found that wild blueberries increased fat-burning during moderate-intensity exercise: “They accelerate fat oxidation—the process of breaking down fatty acids or burning fats for energy.” They also activate enzyme pathways like AMPK and boost metabolism.
3. Turmeric (Curcumin)
Curcumin not only has anti-inflammatory and antioxidant effects, it also stimulates thermogenesis and fat oxidation by regulating metabolic pathways. One report credits it—along with peppers and ginger—for boosting energy metabolism “using mechanisms related to thermal effect, BMR, total energy expenditure, oxygen consumption, and lipid oxidation.”
4. Garlic
Garlic is a powerhouse source of bioactive antioxidants, including allicin, quercetin, and numerous organosulfur compounds. One report notes that “garlic treatment can produce a thermogenic effect, which explains the increase in energy expenditure and resistance to weight gain [in studies].”
5. Coffee
The caffeine in coffee is more than just a little stimulating. Studies show it can have “a significant influence on energy balance and may promote thermogenesis in the treatment of obesity.” Coffee is an antioxidant, anti-inflammatory drink, with studies showing it can reduce metabolic syndrome, type 2 diabetes, and cardiovascular diseases. Another review showed it improves BMI, produces weight loss, and leads to fat reduction.
6. Chili Peppers (Capsaicin)
The capsaicin in chili peppers raises body temperature, boosts metabolic rate, triggers fat breakdown, and may suppress appetite. One study found that “thermogenesis and appetitive control were greater when RP [red pepper] was ingested orally, compared to in capsule form.” In other words, you can tap the spicy benefits during regular meals.
7. Ginger
Bioactive compounds in ginger such as gingerols and shogaols activate TRPV1 and TRPA1 receptors. Studies show they enhance UCP1 expression in brown and beige fat cells, promoting thermogenesis and preventing fat gain. This also includes black ginger, which boosts energy expenditure via brown fat activation.
8. Cinnamon
The cinnamaldehyde in cinnamon supports thermogenesis and helps regulate blood sugar, which in turn supports a stable metabolism. According to one report, “cinnamaldehyde improves metabolic health by acting directly on fat cells, or adipocytes, inducing them to start burning energy through a process called thermogenesis.”
9. Cacao
Flavanols derived from cacao extract have been studied for their role in activating brown fat and supporting thermogenesis. They’re part of a group of compounds—including catechins and capsaicinoids—shown to stimulate brown adipose tissue. One report found that cacao improves glucose and induces the browning of white adipose tissue.
10. Grapes (Resveratrol)
Resveratrol and ellagic acid, polyphenols found in grapes, can promote thermogenesis and enhance fat metabolism. Studies show that “resveratrol increases brown adipose tissue thermogenesis markers by increasing SIRT1 and energy expenditure and decreasing fat accumulation in adipose tissue.”
11. Avocado
Avocados are packed with healthy monounsaturated fats that boost metabolism and exert thermogenic effects. One study found that “inclusion of one fresh avocado per day over 3 months had abdominal adiposity lowering effects.” Their consumption has been linked to a reduction in visceral belly fat, enhanced fat burning, and much more.
12. Leafy Greens (Spinach, Kale, etc)
Low in calories but high in fiber and nutrients, leafy greens boost digestion, satiety, and metabolic health. Spinach is one of the most nutrient-dense and increases methylation via its high folate levels.
13. Soy Foods (Tofu, Tempeh)
Organic soy foods like tofu, tempeh, and miso pack spermidine—a bioactive compound that facilitates thermogenesis in adipose tissue. One study found it “activates adipose tissue thermogenesis through autophagy and fibroblast growth factor 21 (FGF21) signaling.” It’s also been shown to boost weight loss, insulin sensitivity, and the gut microbiome in studies. Read up on spermidine here.
14. Nuts & Seeds
Despite their density, nuts and seeds—like walnuts—have a notable thermic effect, helping increase metabolism via slower digestion. One study found that “in an acute-feeding setting, the consumption of a meal containing walnuts (33% of energy from PUFAs) increased diet-induced thermogenesis significantly.”
15. Beans and Legumes
High in plant-based protein and fiber, beans and legumes require more energy to digest, supporting satiety and the thermic effect of food (TEF).
