Can I drink alcohol on the programme?

Alcohol affects the quality of sleep and disrupts various hormones in the body such as insulin, cortisol, and hormones involved in satiety, all of which have a knock on effect and make it harder to lose weight. It is also packed full of calories. Drinking too much while on weight loss injections also increases the risk of low blood glucose levels, so if you do drink, drink in moderation. Interestingly, an unexpected side effect that has been reported is that alcohol can lose its appeal because, in the same way it does for cakes and chocolate, the medication reduces the effect it has on the reward pathways of the brain.
