Fruit DOES NOT give you a sugar rush! Jeez people.
It's not on iDave's diet because it's a low carb plan (I think). That doesn't mean carbs are bad, or the only way to lose weight is to cut carbs. iDave's plan cuts out lots of healthy foods, doesn't mean they are 'bad for you' or 'fattening'. The iDave diet is not a low calorie plan, just a low carb plan. I think the aim is to persuade your body somehow into fat loss.
