The goal of this clinical trial is to improve the treatment of hepatic steatosis associated with obesity with pharmacological and nutritionnal approaches. The main question it aims to answer is:
Does an individualized nutritionnal approach with a dietician combined with medication targeting obesity is the most efficient way to treat hepatic steatosis associated with obesity?
Participants will either participate in one of three groups:
* Nutrition: Participant will only have a regular follow-up with a registered dietician; * Nutrition + Semaglutide: Participants will start a new medication targeting obesity and will have a regular follow-up with a registered dietician; * Semaglutide: Participants will start a new medication targeting obesity.
