Coffee itself does not contain any significant amounts of calories or fat, so drinking coffee in moderation is unlikely to cause weight gain on its own. However, some coffee drinks, such as those made with sugar, cream, syrups, or whipped cream, can be high in calories and can contribute to weight gain if consumed in excess.
Additionally, caffeine in coffee can have an impact on appetite and metabolism. Some people may experience a temporary decrease in appetite after drinking coffee, while others may find that caffeine increases their hunger. In either case, it's important to be mindful of the overall calorie intake and choose healthy food options to maintain a healthy weight.
Overall, drinking coffee in moderation is unlikely to cause weight gain, but it's important to be aware of the potential high-calorie additives and to balance coffee consumption with a healthy diet and exercise routine.
