The 800 calorie diet is an intensive, 12-week, Med-Style low-carb diet. It is based on the findings of the UK-based DiRECT trial, which showed that a 12-week very-low-calorie diet (VLCD) was capable of bringing about not just substantial weight loss, but reversal of Type 2 diabetes, over a one-year period in a primary care setting.
12 months after beginning the diet, 24% of the VLCD (800 calorie diet) group, compared to 4% of the control group (who were given standard weight loss advice only) had lost 15kg or more. Likewise, 46% of the VLCD group achieved full remission of their diabetes 12 months after starting the diet, compared to 0% of the control group.
This 800 calorie diet approach is a challenge and requires determination, planning and focus. The benefits, however, are rapid in terms of weight loss and improvement in blood sugars. Aim for 10-20% weight loss and then switch to another track, or continue for up to twelve weeks, depending on your original weight.
