Michael Mosley shares why non-restrictive diets are 'better' for weight loss long-term

He added: “Also, you can have the occasional glass of red wine, so I think that for many people is more sustainable and is seen very widely as the healthiest diet on the planet.”

He calls this stage the “maintenance phase”, which helps people maintain their achieved weight loss.

It is designed to fit personal goals and to work with a person’s lifestyle and can include a weekly fast day if needed.

Foods on the Fast 800 Keto diet include:

Protein – oily fish, prawns, chicken, turkey, pork, beef, eggs, beans and dairy

Healthy fats – avocado olive oil, nuts and seeds

Vegetables – nothing is off limits
