A liquid formula diet defines diets based mainly on pre-made, liquid meal replacement packets.
The primary function of such diets is weight loss. The use of meal replacements ensures there is no need for calorie counting. The majority of liquid diets use liquid meal replacements in combination with a low-calorie diet, whereby the dieter consumes 800-1000 calories a day.
The majority of liquid Diets are protein-based. Therefore, the body is able to burn off already-digested fat. The best known ones are Slimfast, Medifast and Scan Diet.
The following foods permitted on a liquid diet:
- Lean meat, like poultry or fish
- Nothing is forbidden on a liquid diet
