The biggest mistake most patients make is that they think they can eat a little fruit every day, because they like it, and still lose weight. In general, this doesn’t work. If you want to lose weight on a low carbohydrate diet, you can’t eat fruit – because fruit metabolizes to twice as much alpha glycerol phophate as simple carbohydrate, so it causes twice as much fat storage. The most efficient weight loss happens on less than 20 grams of carbohydrate a day, and less than 8-10 grams of carbohydrate per feeding. The average serving of fruit (1 apple, 1 orange, 1 pear, etc.) is 20 grams of carbohydrate. If you want to lose weight quickly and efficiently, you cannot eat fruit, because fruit causes too much fat storage. To lose weight efficiently, limit your calories to 1500 or day, or limit your calories to 1000 a day if you can – and eat just protein and fat.
