There is a dizzying array of dietary plans out that can aid weight loss and it can be hard to know where to start. If you want to “kickstart” weight loss, calorie restricted diets can help, advised Dr Amir Khan on Channel 5‘s Lose a Stone in 4 weeks for summer. The fast 800 diet is one of the most effective calorie restricted diets if you want to lose weight quickly, he explained.
The Fast 800 diet – pioneered by Dr Michael Mosley – turbocharges weight loss by restricing calorie-count to 800 calories a day for the first couple of weeks.
“This puts your body into a ketogenic state that should help you to lose weight,” explained Dr Amir.
You then progress to 5:2 stage – where you’re only required to eat this number of calories for two days a week, while adhering to a sensible diet on the other five days.
The dietary plan involves sticking to a low-carbohydrate Mediterranean-style diet.
The Mediterranean-style low carb approach is a low sugar diet, low in starchy, easily digestible carbs.
It is rich in olive oil, fish, nuts, fruit and vegetables.
“Avoiding sugary and starchy carbs helps control your blood sugar levels, and eating adequate amounts of protein and healthy fats will keep you feeling fuller for longer,” explained Dr Mosley.
“No longer is healthy eating about starvation.”
There is an important reason why diets such as the Fast 800 do not maintain the low-calorie approach.
Although very low calorie diets are an effective way to lose weight quickly, they are not advisable in the long-run, warned Dr Amir.
“Very low calorie diets should only be followed under medical supervision for a maximum of 12 weeks,” advises the NHS.
Although very low calorie diets can lead to short term weight loss, it is likely that the weight will come back on after the diet ends, notes the health body.
