Very Low Calorie Diets

A Very Low Calorie Diet is a diet where normal meals are replaced with drinks, soups, or bars. The typical daily calorie intake is on or under the 800 mark - however the aim is to be as nutritionally balanced as possible.

Prescription Only

A Very Low Calorie Diet is normally only used privately and in the medical profession to bring about rapid weight loss in the dangerously overweight person. These diets should be undertaken only under medical supervision. They are typically a high fat, high protein diet that will bring about Ketosis.

The diet is only undertaken for a short period of time (a few weeks). In some situations, the meal replacements may only be used for two meals a day - therefore bringing about slower but more manageable weight loss.

A Very Low Calorie Diet

Medifast
This has been used by (apparently) over 1 million people, and is endorsed by John Hopkins University. It’s a meal replacement plan around the 800-1000 calories mark (which puts it outside the strict definition of a VLCD). It will put the body into a mild state of ketosis.

Optifast
Available at hundreds of clinics in the US and Canada. However many find it difficult to complete the program

The Cambridge Diet
Used in the UK, this diet has an even lower daily calorie level (400-600) and is a high protein, low fat, low carb diet.
