Drinks such as milk, green tea, casein, and thermogenic beverages are known to boost the effects of exercise.

Exercise promotes thermogenesis, wherein the body generates heat as it burns stored fat for energy. Certain beverages have been shown to enhance this process, effectively increasing the rate at which calories, particularly fat, are burned during physical activity. Here are some drinks known to aid in fat burning during exercise:
Drink milk
According to a recent study published in the “Journal of Nutrition” (September 2011 issue), it was found that protein-rich and dairy foods contribute to weight loss in overweight and obese individuals. Participants who incorporated more dairy products into a high-protein diet after exercising experienced greater loss of fatty tissue and weight. Additionally, their body composition shifted to a higher ratio of muscle to fat.
Thermogenic drinks
A commercially available thermogenic drink is designed to enhance fat burning during and for several hours after exercise. These beverages function by boosting the body’s energy expenditure.
A study published in the “Journal of the International Society of Sports Nutrition” found that young men who consumed a commercial thermogenic drink experienced a greater increase in energy expenditure compared to those who consumed a placebo.
Green tea
Green tea has been shown to increase energy expenditure or thermogenesis over a period of 24 hours, as supported by a study published in the July 2011 issue of “Obesity Reviews.” This effect is attributed to the presence of caffeine and catechins, which are antioxidants found in green tea.
However, findings from another study assessing the effect of green tea on weight loss differ. While green tea was found to be beneficial for weight loss, its role in the mechanism of fat burning remains unclear.
Casein
Casein, a phosphoprotein, is considered one of the most thermogenic proteins. It has been linked to greater reductions in body fat, particularly when combined with an exercise program.
A recent study conducted in Switzerland found that individuals who consumed casein protein reported feeling satiated for a longer period compared to those who did not.
