Low-carb protein powders may be beneficial for weight loss due to their high protein content and low carbohydrate content. Protein is known to have a higher satiety effect than carbohydrates or fats, which means it can help you feel full and reduce cravings, leading to a reduction in overall calorie intake.
A 2013 meta-analysis of 24 randomized controlled trials found that high-protein diets (which often include protein supplements) were associated with greater weight loss and reductions in body fat compared to lower-protein diets (1). Another study published in the American Journal of Clinical Nutrition found that participants who consumed a high-protein diet were able to maintain weight loss better than those who consumed a low-protein diet (2).
Additionally, low-carb diets have also been associated with weight loss. A systematic review and meta-analysis of 13 randomized controlled trials found that low-carb diets were associated with significantly greater weight loss compared to low-fat diets (3).
It is important to note that weight loss is ultimately a result of creating a calorie deficit, and protein powders should not be relied on as a sole source of nutrition or as a magic solution for weight loss. Incorporating a balanced diet and regular exercise is also essential for sustainable weight loss.
