What Are Thermogenic Fat Burners?
Thermogenic fat burners are dietary supplements that work by raising your body’s core temperature. This natural process speeds up metabolism and promotes fat burning. The term “thermogenic” comes from “thermogenesis,” which refers to the production of heat in the body.
By stimulating thermogenesis, these supplements encourage the body to use stored fat as energy, helping individuals reduce body fat percentage more efficiently. In addition to fat loss, many thermogenic products are designed to increase energy and improve workout performance.
The most effective thermogenic fat burners typically combine natural ingredients such as caffeine, green tea extract, and capsaicin. These compounds work together to boost calorie burning, support appetite control, and enhance overall weight management.
