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.

I ate all 6 cookies like I was supposed to each day and lost weight from it. :)

Hmm...I lost 3 lbs., but then gained 5 lbs. This is so annoying. I don't particularly enjoy the taste of the cookies, but I really like the convenience of not having to leave for a lunch break at work. One thing I did notice is that I ate all the cookies when I did lose weight. Each day, I ate fewer and fewer cookies, which most likely put my body and starvation mode. I will have to eat all 6 cookies I guess. Also, I got my R and D cookies (peanut butter flavor). Hope they taste better.

Yesterday, I got these cookies on a whim. I was driving to work, had to get something really quick at Walgreens, and stumbled upon Dr. Siegal's diet cookies. First day was rough. I was absolutely starving and like a famine survivor. Second day was totally different. I felt the appetite suppressing affects. Didn't get a chance to weigh myself on the first since I bought these spontaneously on my way to work. I weighed myself this morning--193 lbs. I will report back in a few days. Also, I ordered the R and D cookies to try them out since you guys speak so highly of them.

Hey Guys,

After a lot of reading about Dr. Siegals Cookie, I have official started my diet today 06/15/10. I normally don??t eat dairy products and most other foods ( I am not picky, I just didn??t grow up eating them?), but I am not totally happy with my weight.

I am 135lbs and my target is to be 120-125lbs. My future plan is to maintain120-125lbs by watching what I eat, cause I can??t really afford these good cookies?

Good Luck to all of US!!!

Yes to Barb and yes & no to Sally. I also recommend the R&D Diet Cookie. They taste better and are cheaper. Now Barb, yes, you can go off the diet and go back on and still lose weight. I did it a lot, especially after I was on it for a while. Sally... it is normal for your body to take some time to re-adjust. Use the cookies that taste best and keeps the hunger away and you will be able to wait it out. You won't regret it! I went on the R&D Diet Cookie cookie diet a couple of years ago, lost 70 lbs and have kept them off!

I lost 10 lbs in 25 days. It has been 7 days since and I have not lost anymore . Is this normal? Am i in a starvation mode? or plateau. Any suggestions are welcome.

Has anyone out there been on the diet for a while and gone off for one day and got back on the next day and still loss weight?

posted May 31st, 2010 2:36 pm



Ive been doing the diet for 10 days now and I have lost 6 pounds. I eat the cookies during the day and I eat what I want for dinner (even fast food) but I think because the cookies shrink your stomach, when you can eat what you want its hard to over eat cause you get full on alot less food. :)

The best cookie diet out there is the R&D Diet Cookie program. It's cheaper and they taste better! I lost 40 lbs and have kept them off! Even if you don't want to stay on a very low calorie diet for a long time, it's a great way to "jump start" your diet. It also teaches you portion control and how you are actually supposed to feel. Good Luck everyone!

Let me start by saying before I started the diet I had already changed my eating habits. I cut out fast food, processed food & cokes (I drank 7 a day), but the pounds were SLOWLY dropping. I want to see results to stay motivated. It was so easy to follow ONLY BUY CHOCOLATE. I liked the way they tasted, banana made me want to vomit & oatmeal was 2 sweet! I ate 4 during the day, an early healthy dinner and saved 2 for evening snacks after yoga. I have been off for 4 months and have actually lost 5 more pounds. This should only be used as an aid. If you go back to your old habits you will gain it back!

Im about to start this diet I have alot to weight to lose and this seems pretty extreme, but i think with variables it could be one of the most effective diets available, and reasonably cheap in comparison to what people usually spend shopping

Now I read a lot of people saying they are getting headaches and as someone thats tried the Raw food diet several times im gonna tell you what is more then likely causing them
Most american citizens take in tons of processed foods a day with no nutritional value whatsoever, that being said they are full of highly ADDICTIVE substances sugars, preservatives, sodium, and saturated fats even if you aren't morbidly obese your body is used to these elements being introduced to it on a daily basis, when you go on a calorie restrictive diet 2 things happen. 1. You lose the energy you intake even if you dont expend it, 2. you lose all those addictive properties.

Those headaches, weakness, dizziness, hunger pangs, and other sudden side effects are more then likely just food withdrawal like any addict faces when their fix is taken from them whether it be sugar or heroin.

Now if you have serious side effects after starting the diet like fainting or new heart palpitations, chest pains, or excessive stomach pain, I would reevaluate your diet and go see a doctor.

Keep in mind I myself am not a doctor but a fat man that has experiences with diets in the past.
