The Montignac diet

The Montignac diet is a variation of the combined food diet .

The aim is to avoid combining foods rich carbohydrates with food rich in fat (lipids). This is because of an association of when fat and sugar are eaten together it causes weight gain.

This diet is flexible and easily adapted when out at restaurants. It can be prolonged for several weeks. It causes weight loss but deficiency in nutrients is unlikely.

Other carbohydrates, consumed separately, are authorised 2 to 3 times per week.

Restricted foods and those authorised under certain conditions

  • Foods which have high glycaemic index , such as carrots, potatoes, cereals, beets, white bread are forbidden. The gylcaemic index (GI) corresponds to the speed of absorption and transformation of food into glucose. The lower the GI index the slower the food is absorbed and less sugars it contains.
  • Sugar and food containing sugar should not be eaten
  • Food containing both carbohydrates and fat, such as avocados and chips
  • Nuts, hazel nuts
  • Fruits can be consumed outside but not during meal times
  • Rice, bread, pasta
  • Other carbohydrates, consumed separately, are authorised 2 to 3 times per week .
  • Cereals must be full of fibre and unrefined in order to reduce glycaemic index
  • Cheese can be consumed but without bread
  • Meat can be eaten but without rice or pasta
  • Beer, aperitifs, wine, alcohols... but you may drink 2 or 3 glasses of wine per day after several weeks of dieting.
