Scientists solve mystery of brain switch triggering weight loss in opposite ways

Researchers discovered that both activating and blocking the GIP receptor in different parts of the brain can promote weight loss in mice, explaining mechanisms behind obesity treatments.

• Activating the GIP receptor in the brainstem reduced appetite in mice.
• Blocking the GIP receptor in the hypothalamus removed a brake on fullness signals.
• Findings suggest combining GIP-targeting treatments with GLP-1 drugs could enhance weight loss effects.
