Meal prep with high-protein staples like chicken breast and quinoa works wonders for weight loss, but I think relying on packaged protein bars and shakes is a trap—most are loaded with sugar alcohols and fillers that stall progress. I lost 12 pounds in three months using whole foods, yet a friend saw zero results on the same calorie intake from processed substitutes. Shouldn't we treat whole foods as non-negotiable in any diet plan, even if convenience shouts louder?
