A calorie control diet in which low-fat cookies are eaten to quell hunger, often in place of a meal.

On the Cookie Diet, there are no decisions about what to eat except which flavor cookie to eat, and what to have for dinner. It's a relatively mindless diet strategy that has reportedly helped half a million of Siegal’s patients lose weight.


The cookies contain select amino acids thought to suppress hunger, fiber, and other ingredients that digest slowly to help keep you feeling full. Eating 4-6 of the cookies a day will give you somewhere around 500 calories.

Dinners are simple: Lean protein and veggies, or a light frozen dinner and a salad. The dinners range from a low of 300 to a high of about 1,000 calories each, meaning the diet has a grand total of 800-1,500 calories per day.

Anyone following an 800-calorie per day plan is sure to lose weight, but medical supervision is recommended for people following very low-calorie diets (less than 1,200 per day), as they are likely to be deficient in nutrients. Most of the very low-calorie cookie diet plans recommend a daily multivitamin to fill in the nutritional gaps. (The self-administered cookie diet plans found online recommend higher levels, of 1,400 or more calories per day).

Siegal says his patients have no problems sticking to the 800-calorie limit, and usually drop about 15 pounds per month.

"One of the greatest motivators to sticking to a diet is when you manage hunger, decrease cravings, and watch the weight come off, and virtually everyone will lose weight at 800 calories," he says.
