Typically, people following commercial diets track their daily calorie intake and periodically weigh themselves to monitor their progress. With some commercial diets, participants receive support from health coaches and peer support groups. Many commercial diets also deliver preprepared meals and snacks.

It is important to note that most commercial diets are not meant for long-term use. A person should speak with their doctor to plan how to maintain a healthy diet and prevent rapid weight gain after they finish a commercial diet.

A recent review suggests that healthcare professionals may consider recommending some commercial diets to their patients with obesity. However, researchers have not studied all commercial diets. Therefore, when choosing a commercial diet, a person should speak with their doctor or dietitian to ensure the diet is suitable for them.

We explore nine commercial diets in further detail below.
