Does vitamin B help with weight loss

Vitamin B may have a certain auxiliary effect on weight loss, but relying solely on vitamin B cannot achieve significant weight loss results. Vitamin B mainly affects body weight through mechanisms such as participating in energy metabolism and promoting fat breakdown, but effective weight loss requires a combination of dietary control and exercise.

Members such as vitamin B1, B2, B6 are important coenzymes in the metabolism of sugars, fats, and proteins. Adequate intake of vitamin B helps maintain normal metabolic rate and avoid fat accumulation caused by low metabolism. Clinical observations have found that some obese individuals have a deficiency of B vitamins, and appropriate supplementation may improve metabolic efficiency. However, vitamin B itself does not contain calories and cannot directly consume fat. Its function depends on a negative balance where overall energy expenditure exceeds intake. Excessive supplementation of vitamin B may lead to neurotoxicity or liver and kidney burden, especially the accumulation of fat soluble vitamin B12 in the body may cause adverse reactions. Some products claiming that vitamin B can "dissolve fat" lack scientific basis, and the rapid weight loss effect is mainly due to the diuretic or laxative ingredients added in the product. For obesity caused by thyroid dysfunction, polycystic ovary syndrome, and other diseases, vitamin B supplementation cannot replace etiological treatment.

It is recommended to obtain vitamin B through natural foods such as whole grains, lean meat, and green leafy vegetables, and avoid long-term high-dose supplements. During weight loss, vitamin levels can be regularly monitored and supplemented under the guidance of a doctor. Maintaining a daily calorie deficit of 500-750 calories, combined with at least 150 minutes of moderate intensity exercise per week, is a safe and effective weight loss plan. If there are abnormal weight fluctuations or symptoms such as fatigue and edema, it is necessary to promptly investigate endocrine and metabolic diseases.
