Does drinking black coffee before exercise help burn fat

Drinking black coffee before exercise generally helps burn fat. The caffeine in black coffee can promote fat metabolism and improve exercise performance, but the effect varies from person to person, and excessive intake may cause discomfort such as palpitations. Moderate consumption of black coffee before exercise can stimulate the central nervous system, increase adrenaline levels, and accelerate the breakdown of fat into free fatty acids for energy supply. Caffeine can also delay exercise fatigue, help prolong aerobic exercise time, and indirectly increase calorie expenditure. Research shows that exercising after consuming caffeine can increase fat oxidation rate by about 10% -30%, especially for people with low long-term caffeine tolerance. Some individuals may experience caffeine sensitivity reactions, such as increased heart rate, insomnia, or gastrointestinal discomfort. Drinking on an empty stomach may worsen gastric acid secretion and induce stomach pain. Patients with hypertension, arrhythmia, and pregnant women should avoid consuming caffeine before exercise. Timely hydration is necessary after exercise, as caffeine has a diuretic effect and may exacerbate the risk of dehydration.

It is recommended to drink 150-200 milliliters of sugar free black coffee 30-60 minutes before exercise, combined with moderate carbohydrates to reduce gastrointestinal irritation. Long term dependence on caffeine for fat burning may lead to increased tolerance. It is recommended to control the frequency of use weekly and combine it with high-intensity interval training for better results. Maintain a balanced diet in daily life, avoid excessive intake of caffeine as a substitute for basal metabolic expenditure, and replenish protein and electrolytes in a timely manner after exercise.
