Coffee can suppress appetite and may help you live longer
The 16:8 diet is a time-restricted form of intermittent fasting. It involves an 8-hour window for food consumption and fasting for the remaining 16 hours of the day. During the fasting period, it is recommended to drink calorie-free beverages like water or unsweetened teas and coffee.
Several studies have found that drinking coffee reduces the risk of developing diabetes, mental illness, many cancers, and overall mortality. Coffee contains caffeine, which can increase fat oxidation and slightly increase the number of calories burned. Caffeine also has diuretic effects, increasing urine production and resulting in the loss of water weight. However, these effects are short-lived and do not lead to significant weight loss over time.
In addition to caffeine, coffee contains polyphenols, a type of antioxidant that may affect weight. Chlorogenic acid, a polyphenol found in coffee, helps maintain stable blood glucose levels, which can help regulate appetite as food cravings are related to blood sugar fluctuations. While coffee may not lead to significant weight loss, it may prevent weight gain and modestly influence weight management.
It is important to note that the effects of coffee on appetite and weight management are not fully understood, and individual results may vary. While coffee can be a helpful tool, a well-rounded approach to health and weight management should also include a healthy diet and physical activity.
