Collagen is not a direct “weight loss product,” but it may offer indirect support. Collagen peptides are a protein source, and protein can improve satiety, potentially reducing snacking and making calorie control easier for some people. For those doing resistance training, adequate protein supports muscle retention, which helps limit metabolic slowdown during dieting. However, the core truth remains: weight loss is driven by energy balance, diet quality, and consistent movement. Collagen can be an auxiliary tool within that system, not a standalone solution. The best positioning is operational: collagen supports the plan, but it is not the plan.
