Hormonal

Once-weekly semaglutide (1.0 mg) reduces ad libitum energy intake by approximately 24% through mechanisms of reduced appetite, improved control of eating, and lower preference for high-fat foods, leading to significant body weight loss without compensatory increases in energy expenditure.

Take once-weekly semaglutide (titrated to 1.0 mg over 12 weeks) to reduce hunger, improve control over eating, and lower preference for high-fat foods. This leads to a ~24% reduction in daily calorie intake and significant fat loss, without needing to increase exercise or metabolic rate. Expect mild GI side effects initially.

GoodSupportsHIGH confidence
After 12 weeks of treatment, ad libitum energy intake was substantially lower with semaglutide vs placebo with a corresponding loss of body weight observed with semaglutide. In addition to reduced energy intake, likely mechanisms for semaglutide-induced weight loss included less appetite and food cravings, better control of eating and lower relative preference for fatty, energy-dense foods.
