How is the weight loss effect of exercising after drinking coffee

Exercising after drinking coffee may help improve weight loss, but it needs to be adjusted according to personal constitution and drinking habits. Caffeine can promote fat metabolism and enhance exercise endurance, but excessive intake may cause palpitations or affect sleep. The caffeine in coffee stimulates the central nervous system, which can improve energy expenditure efficiency during exercise. Moderate consumption of black coffee before exercise can help break down fat cells, allowing fatty acids to enter the bloodstream more quickly for energy supply. Studies have shown that caffeine can increase the rate of fat oxidation during exercise, especially during moderate intensity aerobic exercise. Caffeine can also delay muscle fatigue, allowing people to persist for longer periods of time in sports such as running and cycling, indirectly increasing calorie expenditure. It is recommended to choose sugar free and milk free black coffee and drink about 200 milliliters 30-60 minutes before exercise. Some people may experience discomfort such as palpitations and hand tremors after drinking coffee, and these groups should avoid caffeine intake. People with gastrointestinal sensitivity who drink coffee on an empty stomach may experience stomach pain. It is recommended to pair it with a small amount of whole wheat bread. Drinking coffee before nighttime exercise may interfere with melatonin secretion, leading to difficulty falling asleep and affecting metabolism. Patients with hypertension or arrhythmia should consult about caffeine, which may increase the burden on the heart. Long term dependence on caffeine for alertness can lead to tolerance and gradually weaken weight loss effects. During weight loss, coffee can be used as an exercise aid, but daily caffeine intake should not exceed 400 milligrams. Suggest pairing a high protein diet with strength training to avoid relying solely on caffeine. Timely replenishment of water and electrolytes after exercise may accelerate dehydration due to the diuretic effect of coffee. People with poor sleep quality should choose to exercise in the morning and avoid caffeine intake in the afternoon. If there is persistent palpitations or insomnia, stop drinking and seek medical evaluation.
