Do You Know the Best Diet Shakes of 2022?


Eat your cookies and lose weight? Sounds like a diet dream come true. Dr. Siegal's Cookie Diet plan is a program that helps you to lose weight while munching on his low-fat and protein-filled cookies, which are also specially-formulated to suppress appetite via its secret recipe of key ingredients.

For more than 30 years, Dr. Siegal has been preparing, baking and distributing these cookie snacks to help people manage their weight loss goals. He still continues to personally mixes every batch of his proprietary protein formula in his private bakery near his Miami medical clinic.

Here is how The Cookie Diet works:

You eat six of these specially-formulated cookies during the day in addition to one meal eaten at the end of the day. A typical day is comprised of about 800 calories and 70 grams of carbohydrates. You can also eat the cookies in conjunction with another diet.

In April of 2011, Dr. Siegal's announced a new weight loss plan, called Dr. Siegal's Plan 10X. The New Plan 10X cookies are 60 calories apiece, and one or two should be eaten every two hours, up to 9 cookies per day at set times. The classic plan is also still available.

In addition to cookies,Dr. Siegal also has a line of shakes and soups. By following this very low-calorie diet plan you can expect to lose up to 15 pounds in one month. Dr. Siegel’s cookies are available for purchase online, through professional resellers, drug stores, doctors or at one of Dr. Siegel’s retail store locations.

Denise Richards, Jennifer Hudson, Snooki, and Kelly Clarkson have all lost weight on Dr. Siegal's Cookie Diet.

  • Idea of eating a cookie might prevent diet binges
  • Cookies contain satiating protein and amino acids
  • May help to suppress hunger
  • Many people have had success with losing weight following this plan
  • Contains an organized and structured eating plan
  • Complementary cookbook available
  • No clear exercise guidelines are given
  • Very low-calorie diet plan
  • Dr. Siegel’s Cookie Diet may not be a long-term solution to weight loss
  • Meal-replacement diets rarely result in sustained weight loss

On The Cookie Diet, you will eat six cookies throughout the day in addition to one meal at the end of the day. That meal should include six ounces of lean white meat protein and one cup of vegetables.

The diet 1000-1200 calories a day. Each cookie contains 90 calories and each dinner should contain no more than 500 calories. If you're looking for meal ideas that complement the diet, then look no further than The Cookie Doctor Cookbook, which offers 120 recipes that don't exceed 500 calories.

In addition, you should consume eight glasses of liquid a day (ideally water). Coffee and tea are allowed on this diet. There are five varieties of Dr. Siegal's cookies that you can choose from: chocolate, oatmeal raisin, coconut, banana, and blueberry.

Dr. Siegal’s shake mixes offer an alternative to his cookies and contain the same hunger-controlling amino acid protein blend. They come in chocolate, vanilla, strawberry, crème brulee, and pina colada flavors.

While the ingredients are all-natural, and the ingredients label full of things you'd recognize or be able to pronounce, there is some concern with a few inclusions. For one, the first ingredient is sugar, with 9 grams in a serving. Next, the cookies are almost completely void of the dietary fiber, with less than a gram per serving, a necessity in satiation. However, in our interview with Dr. Seigal, he sites a "particular mix of proteins" as being key to keeping users feeling full. Finally, it should be noted that the cookies are relatively low in sodium, with no more than 200 milligrams per serving.


Dr. Siegal claims that if you eat his 1,000-calorie a day cookie diet than you can effectively lose weight while doing very little or no aerobic exercise. But he does encourage exercise for weight loss maintenance.


On the face of it, the idea of a "Cookie Diet" sounds a bit bizarre but enticing. Dr. Siegel’s Cookies are on par to meal replacement shakes that pack nutrition in a quantity-controlled product. Critics feel that the diet is too restrictive and too low in calories despite the thousands of people who have had success in losing weight on Dr. Siegel’s Cookie Diet. Since the plan is so rigid, speak with your doctor if you are interested in following this diet.

This is my second time doing this diet. i did it when I had my second son and gained alot of weight while pregnant. I am 5 feet and weighed 142lbs after I gave birth. As soon as my OBGYN gave me the go to diet, I did the Cookie diet with Siegal and in 2 months lost 33 lbs. I returned from my maternity leave skinnier than when I got pregnant! I kept the weight off until I had my third son. That was 11 years ago. With time another pregnancy and age?my metabolism is not the same it was 10 years ago, I have gained 12 lbs which I need to loose. I just started the cookie diet again and have been on it for 8 days and have already lost 7 lbs. I love this diet, it works for me. I believe that all diets work, but you have to find the one that works for YOU! For me, this diet is easy, and perfect for my life style since I am always on the go with 3 boys! I know that I will be back to my regular self in less than a month and then keep eating healty and doing my daily excercizes to maintain! Thanks Dr. Siegal?

I love this diet!!!! It was very difficult at first as I felt like I was going through withdrawl symptoms. I had the worst headaches ever! I am so glad I stuck this out. This is the start of week 3 & I have lost 14.6lbs!!!! I love the cookies! They taste great warmed up!

which is it? High fiber or low fiber? Can't be both! Even within this same article, the opening paragraph calls it a high fiber cookie and near the end it says "the cookies are almost completely void of the dietary fiber, with less than a gram per serving". So why did you open with calling them "low-fat, high fiber and protein-filled cookies"?

High fiber? Your other article says there is only one gram of fiber. Which is it?

Can you eat a frozen diet meal as your meal of the day? As long as it is 500 cal or less?

This diet is the best. I lost 100 lbs. and have 10 more to go and I'm in my 7th month. Convenient, affordable, and easy. You can see my story on the thecookiediet.com website if you are interested. I am Ben (Benny) from La Crosse. Follow the program and you will lose weight, it's that simple. I've suffered through other diets in the past but this diet did not feel like suffering at all. Good luck to anyone just starting.
