Meal-replacement bars can be healthy depending on ingredients and frequency

Meal-replacement bars can be nutritious when they are high in protein, fiber, and essential nutrients; some bars contain added sugars, extra calories, and artificial ingredients and should not replace all meals.

Meal-replacement bars are presented as a potentially convenient source of nutrition that may support weight-loss goals for some people. The article, reviewed by Lynn Marie Morski, MD, JD, emphasizes that bars vary widely in composition and that whole foods remain the preferred source of nutrients. Experts quoted in the piece note portability and protein content as practical benefits. The article also addresses how bars may fit into plans that include weight-loss medications. Main points: - Bars high in protein, fiber, and added vitamins and minerals are described as more nutritious and can help meet protein targets reported for weight-loss efforts. - The article reports benefits such as support for muscle maintenance, appetite control, and potential help with cravings when protein intake is adequate. - It notes downsides including added sugars, high calories, artificial ingredients, possible nutrient gaps, and gastrointestinal effects like gas or bloating. - The article mentions that meal-replacement bars can be useful for people on GLP-1 weight-loss medications because they may be easier to consume when appetite is low or nausea occurs. - Experts quoted include Mike Bohl, MD, who described shakes and bars as portable, and Craig Primack, MD, who discussed protein targets for weight loss. Summary: Protein-rich meal-replacement bars can complement a diet when their nutrient profile aligns with an individual’s needs, but their effect on weight depends on total calories, sugar, and how often they replace whole-food meals. Undetermined at this time.
