I fucking hate this statement. It is complete bullshit. No matter what you eat, you are on a diet. Counting calories is a diet that works permanently. This change must work with your lifestyle, but the diet still always works, forever. It is necessary to permanently change your diet, for weight loss, calling it a lifestyle change is just changing what you call it. You are just feeding in to the whole "teehee, diets don't work" when they absolutely do.
