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.

Banana cookies suck unless warmed up in microwave and sprayed with Smart balance spray butter. Chocolate cookies excellent. Been using the Smart For Life Diet cookies instead, and they are awesome! They are also less expensive when ordered through Costco. Lost 25 pounds in 3 months, and didn't totally give up alcohol as suggested. Still feel like I am taking care of my cookie cravings and getting my chocolate fix. Love it! But wouldn't do Dr. Seigal's cookies over the Smart for Life diet cookies if I had to choose. Dr. Seigal charges WAY too much for shipping as well. Good luck!

I have been on the diet since April and have lost 42 lbs. It works. Regarding the negative postings, A lot of them look suspiciously like ads to pitch the Smart for Life Products. Treat them that way ignore the BS.

I ordered 3 weeks of Dr. Siegel's cookies; after 1 month and 1 week, I had lost a total of 17 lbs. Originally I weighed 149 lbs and went down to 132 lbs.
To be honest, the cookies are fairly bland tasting, but if you really stick to this diet and watch your total calorie intake, this diet really works! I have kept the weight off now for 6 months.
The cookies are great because I carried them in my purse and when I was driving anywhere and got hungry, I just ate a cookie as oppose to pulling into a fast-food drive-thru.

Keep it up guys. This diet works! just think about the results.

before starting the cookie diet, i was skeptical & read everyones blogs so i couldn't resist after giving it a try.

i am over 50 lbs heavier after having my daughter 2 yrs ago.i have been sucessful in the past when doing low carb dieting & exercise, but no luck since the birth of my little girl.this has caused me fustration & somewhat depression.
recently...my coworkers and i started a "biggest loser' contest (money as the incentive of course).so i decided to give the cookie diet a try. may 13th to be exact, i weighed in at 203 lbs. today only a week and a day later, "8 days that is," i am 191 lbs!!!! i still cannot believe it!!!! its a little crazy i know, but true, honest to God!
anyway, i will admit, besides the cookies, i have been exercising everyday for less than an hour (walk away the pounds dvd, its really great) and eating a low carb meal at dinner.but i'm a witness that this is really working.
i will continue to report my weight loss periodically.
ps...the contest is over in 2 months.i'm so excited i'm going to win!!!! lol

The diet is hard the first few days, you are so used to eating real food so when you don't you feel hungry but really aren't. I got headaches for the first 3 days but I am pretty certain this was due to me not drinking pop anymore and having caffeine withdrawls.

I am 6'4" tall and started at 255, I am now at 240 after 4 weeks. I cheated like no other in week 3 and luckily didn't gain any wieght back. I have gotten to the point where if I only eat the cookie when I am actually hungry, I end up only eating 4 or 5 of them.

BUY THEM OFF OF EBAY THEY ARE CHEAPER. ABOUT 45-50 dollars a week rather than 59 a week.

I lost 20 lbs in five weeks but honestly it almost drove me insane. Cookies and more cookies and the meals were dull and I craved fruit hugely. I say honestly weight watchers is the best and exercise.

I have been on the diet for two weeks. About two hours after I eat them I feel nauseous and develop heartburn. NO Refund so I'm stuck with them. Does anyone know which ingredient might cause this reaction?

NOT Sure is I like it. I have had a dull headache since startin g oit 3 days ago. Anyone experience this issue?

I have been on this diet now for 6 wks. We call it the smartforlife diet. I have lost 20 lbs so far and feel amazing. My husband has been on it for 3 wks and has lost 13 lbs. I found though that you have to stick with it, no cheating, take lots of vitamins.

So far, so good. I'm on day 4 of the diet, and it's getting easier as I go. The first couple of days, I struggled. I felt hungry (more psychological than physical), and I had a hard time getting the cookies down. The texture is quite spongy, yet the cookies seem dry. Very weird consistency! Thanks to the reviewer who suggested heating them up, I am finding that they aren't too bad and they are completely satisfying my hunger (and I'm not even eating all 6). I'm down 4 lbs already, so I'm hopeful that I'll meet my goal of a 15 lb loss. I don't mind exercising at all, but due to an injury, I'm limited to reducing calories at this point. The cookies are easy -- no calorie counting, no food planning, and easy to bring along with you.

I love it, I have been on this diet for 3 weeks and have lost 13 pounds. The first two days were the hardest, but I got used to eating the cookies, I can't wait to lose more, more, more. This is by far the easiest diet I have ever been on. And I work out about 3 times a week too.

I started my cookie diet 4/13/09 the 1st day was so hard to just eat cookies all day except for dinner but after that I would even look forward to having a cookie. I am 26 yrs old 5.3" tall & before the diet I weight 146 as of this morning my weight is 140 lbs I am hoping to go down to 129 lbs....This diet is great, fast and easy to loose weight. ;)

Only 3 days in but have lost about 4 lbs and the cookies are good. The chocolate and the raisin oatmeal are best. The only downfall is my energy gets very low in the afternoon until I eat dinner.. But if that is the only downside I am ok with that.

I have been on the cookie diet for 6 days and have not lost ONE pound. I don't get it. I only eat the cookies during the day and drink water and coffee. Maybe I'm eating too much at dinner but I don't think so. I even started exercising again. Maybe I have a thyroid problem :( but I am not overweight and haven't had a problem losing weight when I was younger. Thoughts?

You do not need cookies to lose weight on 800 calories a day....of course you are going to lose weight on that many calories

posted Mar 20th, 2009 5:06 pm


I think the diet cookies from Smart For Life is better. They taste better and are made better. The weight loss/diet program worked for me. Visit their site and judge for your self
