Nutrition experts outline sustainable weight‑loss diet plans

Nutrition specialists emphasize that effective, lasting weight loss should avoid severe calorie restriction and instead focus on balanced, protein‑rich meals combined with ample fiber from vegetables, fruits, legumes and whole grains. They note that low‑carbohydrate diets can produce rapid initial weight loss due to water loss from depleted glycogen stores, but research shows little long‑term advantage over moderate‑carb approaches.

Sustained results depend on overall energy balance, regular physical activity, adequate hydration, and consistent sleep. Experts advise limiting refined sugars and processed grain products while preserving essential nutrients, and caution that overly restrictive carb elimination may reduce fiber intake, leading to digestive issues. They recommend portion control, inclusion of quality protein sources such as eggs, fish, dairy, and plant‑based options, and a diet rich in fruits, vegetables, and whole grains for optimal health and weight management.
