The forever slim diet is a low carb diet as well.
You dont eat any carbs whatsoever until after 6-00pm.
After this time you can have your allotted carb for the day.The carb total for each person is worked out according to their correct height to weight ratio.In my case because Im 5 feet 3 inches I should weigh 60kgs and therefore should eat only 37 grams of carbs per day.
We can eat any kind of carbs after 6-00pm as long as they dont exceed the allotted amount.
I hope this sort of explains the diet.
