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 started my cookies today. I have the chocolate ones and they taste like brownies to me!! Towards the end of the day when it was time for dinner I felt a little drained, light headed, and a little hungry. I only ate 4 of the 6 during the day and had brocilli and 6 ounce tyson steak strips for dinner. I'll keep you guys posted

Not sure if I like it yet...I just started it today. And it is true that they are not very tasty(doing the coconut), but if it will jumpstart my weight loss than I can stomach them for a couple weeks. I plan to use them for no longer than a month in conjunction with the exercise that I already do. I am at 141.4 lbs and the goal is 120 lbs. While I am realistic that I am not going to loose 20 lbs in a month...this should help to get it going. Also the cookies are a little better if you microwave them for about 10 seconds.

I just started the cookie diet (for the people against the diet, THEY DON'T TASTE LIKE COOKIES) on Sunday 1/3/10. I needed to get back in control of what I am eating and teach myself to eat small meals all day long. That is what this diet is doing, limiting your intake & srinking your stomach. So far it is 1/5/10 and I am down from 170 to 166. I am so excited because my hardest thing with a diet is not seeing results. I will post more next week.

I heard a lot of good things about this diet, and really wanted to try it. I ordered the coconut and oatmeal cookies, one box each, and found the taste to be so bad that I cannot even eat them. They have a terrible aftertaste, and I could not even finish a cookie. I really wanted to do this diet, but they taste horrific. It was suggested that I drink a glass of water after eating the cookie, but I found I had to drink a glass of water just to get the cookie down. I would like to get a refund.

I have only been on the diet for a few days, but I've already lost a few pounds and I think I can stick with it. I like the way the cookies taste. If they were any tastier, I think I'd just want to eat more of them or just more cookies period.

Also, I've been eating a high fiber 300 calorie breakfast and a healthy 400 calorie dinner. Then I eat cookies, cut veggies and lot's of tea in between. This has really helped me, because my breakfast allows me to go 4 hours before I'm hungry. And I really don't need a big dinner because I eat late.

My plan is to keep this up until I lost 11lbs and then I'll substitute a small healthy meal for 2 of the cookies, then for 4 of the cookies... until I've weaned myself off of them. And all the while I'm working out with weights every other day.

My favorite part of this diet is that since I'm so busy with my kids I can eat on the run, rather than becoming so famished that I eat the whole house when I get home.

KD....I too have been tweeking the cookiet diet the last month and having 1 or 2 cookies and the rest food up to 1000 calories. I've been choosing more vegetables, lean meats and fish, some fruit, nuts and grains....trying to keep it a well balanced diet. Trying to stay away from processed foods.....still taking my daily vitamins and 30 min to 1 hour of exercise a day (started the exercise about 2 weeks ago). My cravings for sweets have gone way down. Today is day 56 and I have lost 27 lbs after the first month I've been losing at a rate or 1 to 2 lbs. a week. . I am grateful I found Dr. Seigal's Cookie Diet....it really has been a great way to jump start my diet. I understand I won't be able to live on Dr. Seigals cookies......that is why I incorporated healthy food because once you lose weight the important part is keeping it off so you must have a plan and it needs to be something you can realistically do each day. Good luck to everyone!!!

I posted about a month ago that I was on Day 2 and felt pretty good. It's been a little over a month now and I've lost 16 lbs. If you can make it through the first week, it really gets pretty easy. This month I'm substituting small meals for some of the cookies in order to make the cookies last longer, since they're quite expensive. This will help when I reach goal and start eating regular food. So far so good... lost 2 lbs this week.

I posted about how horrible the oatmeal cookies are a few days ago. I have since been heating them up, which does make them easier to eat, but they are still quite far from good..............Today was my first weigh in, and I've lost 5 lbs. I'm very happy with the effort required and the results so far. I hope to see more results next week!

i went on this diet for a month and a half and only lost 10 pounds. the last two weeks while on the diet, i didn't lose anything. i know it's not a healthy diet so since then, i've started having 3 small meals a day all totaling 1000cal. if i feel hungry in between, i have a cookie.

I've actually started losing again after modifying the diet. i have lost 3 pounds in 3 days. also, i now have regular bowel movement which i didn't have while eating the cookies and just one meal.

I was on this diet last year and lost 74lbs in 3 months. I did exercize with it also. Within those 3 months I broke 4 teeth (root canal's) and started to loose my hair. My Dr. told me to get off of the diet. A year later, I have gained back 50lbs but at least my hair is growing back.

I started the diet the day after Thanksgiving and after 7 days have lost 7 pounds. I am adding light exercise, walking briskly. I drink lots of water, and try to have around 300 to 500 calories in the evening depending on how hungry I am. I am really surpised at the results. I like the choc cookies warmed and are really good. I have tried everything from Weight Watchers, etc., and nothing seems to work, but this does. I am 5ft 4 inches and weighed 172 when i started, and would like to get down to 145 to see how I feel. We all like to see results and with this you will get it! It will be interesting to see the results in two months! I understand what readers are saying, but this is working for me!

Today is my 3rd day on the diet, and so far, it's been pretty easy. On Sunday and Monday, I ate the chocolate cookies, but today I had the oatmeal raisin ones. I had to choke the oatmeal raisin ones down. They are absolutely horrid. However, I will continue with this diet because it is so easy and the chocolate cookies are quite pleasant. Next month, when i order another box, I'll try to get an all-chocolate box....

I lost 5 lb in 3 days combining this diet with exercise. Yes, its not completely healthy. Yes, its a bit of a fad. But I am losing weight, and that is what I wanted, so count me as a fan.

I've modified the cookie diet and its working for me. I think the ultimate goal is to eat 1000 calories (since each cookie is 90 calories and you get a 500 calorie dinner) So, I eat about 2-3 cookies a day which allows me to each a small lunch (usually a frozen weight watchers meal 280 claories) and then a light dinner as well. I still say under 1000 calories. The cookies don't taste that well, but I was surprised to find that they taste A LOT better when heated. My method seems to be working and I am losing weight. My modified plan is more about portion control. I'm still eating and still losing weight.
