Can drinking coffee on an empty stomach in the morning help with weight loss

Drinking coffee on an empty stomach in the morning may be helpful for weight loss, but the effect is limited and there are health risks involved. The caffeine in coffee can temporarily increase metabolic rate and suppress appetite, but long-term dependence on drinking on an empty stomach may stimulate the gastrointestinal mucosa and cause discomfort. Caffeine promotes fat breakdown by activating the sympathetic nervous system, which may increase calorie expenditure in the short term. Some people experience a decrease in appetite after drinking, indirectly reducing calorie intake. Black coffee itself has extremely low calories, and replacing high sugar drinks can avoid additional calorie intake. Research shows that caffeine can slightly increase basal metabolic rate, but this effect lasts for a short time and varies greatly among individuals. Caffeine is absorbed faster on an empty stomach, which may enhance the aforementioned effects, but also exacerbate the irritation to the gastrointestinal tract. Drinking coffee on an empty stomach may cause excessive secretion of stomach acid, leading to discomfort such as acid reflux and stomach pain. The diuretic effect of coffee may cause water loss and be mistaken for weight loss. Long term consumption on an empty stomach may affect blood sugar stability and increase the risk of binge eating. Some people may experience caffeine overdose reactions such as palpitations and hand tremors. After the formation of caffeine tolerance, the metabolic promoting effect will gradually weaken. Relying on coffee for weight loss may overlook core weight loss methods such as diet control and exercise.

It is recommended to use coffee as an adjunct to scientific weight loss programs. Before drinking, it is recommended to consume a small amount of food to protect the gastric mucosa, and choose low calorie coffee or milk to reduce irritation. The daily intake of caffeine should not exceed 400 milligrams, and avoid drinking it in the afternoon to prevent it from affecting sleep. If symptoms such as palpitations and stomach pain occur, drinking should be stopped immediately. Losing weight requires establishing sustainable eating and exercise habits, and relying solely on coffee is difficult to achieve ideal results.
