How long does it last?
There is no strict duration. “In the context of weight loss, I recommend to my patients an intermittent fast of a whole week, specifies Raphaël Gruman. On the other hand, if it is in view of a digestive well-being, a fast of one or two days a week is more than enough “.

Who is he talking to ?
Only for healthy adults. This eating method is also not recommended for pregnant and breastfeeding women, children and adolescents because it could lead to growth retardation, and for the elderly, which it can further weaken.

What foods are allowed?
On unfast meals of the day, all foods are allowed: cereals and legumes, meats, fish and eggs, dairy products, fruits and vegetables, even pastries and confectionery.

On the other hand, on the fasted meal, only water, broths and herbal teas are allowed.

What foods are prohibited?
On the two to three main meals, if intermittent fasting aims to lose weight, sweets, pastries, confectionery, etc. should be avoided.

During the fasted meal, solid food is prohibited. “Coffee is also not recommended because it requires digestion in the liver”, explains Raphaël Gruman.

Is intermittent fasting easy to follow?
Yes, if it is done on a short phase. When hunger arises, it can be compensated by absorption of liquid: by filling the stomach, they cut the urge to eat. Keeping the mind busy also helps to distract from hunger.

Finally, by going to bed early, fasting the evening meal is easier. “In addition, for lack of food, the body adapts: it transforms fat reserves into ketone bodies, substances that replace glucose, explains our expert. These provide a certain satiety, make you euphoric and do not make the body want to eat more “.
