Looking at the calories on Paleo, No Flour, No Sugar and Atkins – makes it clear why the bet is you won’t lose weight on any of these programs. Say you have an omelet with ham and Swiss cheese for breakfast. IHOP doesn’t sell an omelet with less than 1200 calories. I wish I were kidding. Say you have a couple of tuna salad sandwiches for lunch, and you don’t eat the bread, so you add another 500-600 calories. You have a 3 ounce package of nuts for an afternoon snack, which adds another 450 calories. You eat the topping of a large sausage pizza for dinner, you leave the crust, and you’ve eaten another 1200 calories. You’ve eating 3200 – 3500 calories a day. You’ll maintain or gain weight.
