Male mice received Melanotan II directly into a brain region involved in reward, with home-cage and operant feeding tests.
What the researchers measured
Food consumption, effort to obtain food, taste avoidance, and metabolic rate were measured.
How to read this evidence
Researchers studied cells, isolated tissue, or animals. These experiments can help explain a mechanism, but do not establish benefits or safety in people. Human cells grown in a laboratory also belong in this category.
Results in context
Food intake and motivation changed without the tested metabolic-rate change. Direct brain-region exposure is not equivalent to systemic administration or human appetite treatment.
What this does not establish
Local brain administration in mice is not equivalent to peripheral exposure or a clinical weight-management trial.
