I am talking maintenance here, cheat day stuff, because fruit is one of the two worst things you can eat, if you want to lose weight. Alcohol is the other. Fruit and alcohol both store twice as much fat as simple carbohydrate, as they metabolize to twice as much alpha glycerol phosphate, for twice as much fat storage. But if you are going to eat fruit, eat melon, pineapple and berries. One cup of mixed fruit – one cup of cut up cantaloupe, honeydew, pineapple, strawberries and, blueberries – is about 50 calories. One cup of grapes or cherries is about 110 calories. Four cups of mixed fruit is a ton of food, and less than 250 calories. Four cups of grapes or cherries is almost 500 calories.
