Will drinking red wine at night cause weight gain when trying to lose weight?

Whether drinking red wine at night will cause weight gain during weight loss needs to be determined based on specific circumstances. If consumed in moderation, it generally will not lead to weight gain. However, excessive consumption may result in weight gain. Detailed analysis is as follows:

Red wine contains vitamin C, organic acids, and other substances. Moderate consumption can help promote human metabolism, improve physical fatigue, aid digestion, and reduce blood viscosity, thereby exerting a certain promoting effect on weight loss. At the same time, moderate red wine consumption can also improve sleep quality. Therefore, if red wine is consumed in moderation at night during weight loss, and no other high-calorie foods are ingested, weight gain generally will not occur.

However, alcohol itself is high in calories and is preferentially metabolized in the body. This process inhibits fat oxidation and breakdown. When the caloric intake from red wine exceeds the body's consumption, the excess calories will be converted into fat and stored in the body. Long-term overconsumption inevitably leads to weight gain and negatively affects weight loss efforts.

During weight loss, it is important to maintain a balanced intake of various nutrients, avoid excessive consumption of high-calorie and high-fat foods, and maintain healthy lifestyle habits.
