What is a safe rate of weight loss?

Aim for slow, steady, consistent weight loss of around 0.5 to 1kg per week. This is not a crash diet. Taking time allows your body to adjust to the medication, limits the risk of side effects, and helps protect against muscle loss. If you are older, aim for nearer 0.5kg per week to ensure you maintain muscle mass. Rapid weight loss might seem appealing, but it increases the risk of problems like loose skin, nutritional deficiencies, and gallstones.
