The biggest mistake most patients make on a low carb diet, is that they eat way too many calories. If your calories are much over 1000 a day, the big bet is you won’t lose weight fast enough, to stay motivated enough, to stay on your diet. I’m a big fan of 500-600 calories a day, because the weight loss is very rapid, and rapid weight loss helps you stay focused. The problem is you probably can’t stay on 500-600 calories a day very long, without medical monitoring and support. The monitoring makes sure you stay healthy as you quickly lose weight. The support provides medication and psychological techniques to keep your hunger and carbohydrate cravings under control as you starve. Weight loss is starvation. There’s no other way.
