Eating out can help you lose weight on a low carb diet, because it structures your food intake. Structure is one of the most helpful things you can do, if you want to lose weight. Freely feeding on dead animals doesn’t work, because the big bet is that you will eat way too many calories, so you won’t lose weight. Restaurants, particularaly chains and fast food restaurants, meticulously structure your food intake. Everything is measured and portion controlled. In general, a quarter pound fast food hamburger from Wendy’s or McDonald’s or Burger King is about 200 calories. That piece of salmon at Outback is generally always going to be the same size. That 16 ounce steak at Morton’s will be 16 ounces, not 20. Keep your carb intake under 10-20 grams per feeding. Keep your daily calories under 1500. You’ll lose 3-5 pounds a week.
