QUICK FACTS Start the Diet Now Advertisement
  • Established: 2010

  • Founder: Dr. Mike Moreno

  • Headquarters: Beverly Hills, CA

  • Accessibility: Book, Meal Plan

  • Diet Type: Low-Carb, Low-Calorie

  • Gender: Male, Female

  • Celebrity Endorsements: Dr. Phil, The Doctors


The 17 Day Diet is a weight loss plan available in a book from Dr. Mike Moreno, a family medicine practitioner in San Diego, CA. His book was born of a weight loss plan he prescribed to his overweight patients, namely as a way to manage the holidays. The friendly Dr. Mike, as he is known to his patients, is proactive in helping them manage their health and weight, and even created a program called "Walk with Your Doc" back in 2008. Two days a week he and patients meet for a walk to encourage them to exercise and keep the doctor-patient relationship thriving.

In November 2010, The 17 Day Diet debuted on an episode of Dr. Phil with a raving endorsement from the doctor. That appearance was immediately followed by one on The Doctors (the two shows are jointly produced), and a weight loss challenge between viewers of each program initiated. The self-published book was an overnight success and Moreno's supply could not keep up with the overwhelming demand.

In spring 2011, Moreno fielded multiple offers from publishing houses interested in purchasing the book's rights, and he awarded those to Simon & Schuster, who immediately ran a second printing of the book. The only difference was a revised cover. This second printing helped push The 17 Day Diet to sales of more than one million copies by the end of 2011.

During 2011, Moreno and his publishers also produced the 17 Day Diet Workbook, a Spanish-language version of the book, and started work on a 17 Day Diet Cookbook that will debut in spring 2012. They also started a partnership with Bistro M.D. to manage a 17 Day Diet meal plan, with meals suited to the diet's specifications delivered to customers at home.

How the 17 Day Diet Works

The 17 Day Diet relies on a style of weight loss known as metabolic confusion, which means you're changing up what you're doing on a regular basis to keep your body from settling in to a routine.

Like many popular diet programs, 17 Day Diet is cyclical, using four phases, or cycles, to progress people from start to goal. The diet itself does not actually last a mere 17 days, instead, that is the length of time for each of the four cycles.

  • Cycle 1: Accelerate. Jump start the program and facilitate rapid weight loss, cleansing, and fat burning. Discourages fat storage.
  • Cycle 2: Activate. During this cycle you will "reset" your metabolism.
  • Cycle 3: Achieve. Develop healthy eating habits, and develop a new understanding of how to eat carbs.
  • Cycle 4: Arrive. Considered the maintenance phase and the culmination of what was learned in the first three cycles. On weekends, you have freedom to enjoy just about anything you like.

If you make it to cycle four and have not yet reached your goal, then it is encouraged and advised that you jump back to another cycle and continue your efforts, on schedule. Cycle four is considered the maintenance phase, and is reserved for those who've reached goal by following the guidance outlined in the first three cycles.

The 17 Day Diet provides direction for a healthy way of eating that is sustainable - it's clean, includes healthy carbohydrates, lean proteins, healthy fats, and eliminates processed and fried foods.

The fitness aspect is minimal, especially at the start with only 17 minutes of exercise per day proposed. However, followers are encouraged to do more as they are physically able and comfortable to expand their fitness regimen.

  • Vegetarian-friendly
  • Diabetic-friendly for types 1 and 2
  • Diet is flexible to suit unique dietary needs or taste
  • One-time cost of the book
  • Recipes available on the Food on the Table Meal Planning App

  • Some food specifications create confusion with users
  • Recommended rate of weight loss exceeds most industry standards of 1-2 pounds per week
  • No online community support or access to experts
  • Beginner exercise recommendation is lower than industry standard of 30 minutes per day

The 17 Day Diet makes minimal recommendations for exercise; however, like many diet plans, it does not dismiss the necessity of a regular fitness regimen completely.

For beginners, the 17 Day Diet recommends a mere 17 minutes of exercise each day. This can be as simple as walking, you can follow along with the 17-minute workout DVD that is sold on the book's website.

As you progress through the program, become stronger and more able-bodied (for those with no prior history of exercise), the advice is still loose but encourages you to double or triple the amount of time you spend working out each day. Guidance is given to do activities that you love, with walking always being a go-to sport.

  • Cycle 1: 17 minutes of exercise per day

  • Cycle 2: 17 minutes of exercise per day

  • Cycle 3: 40-60 minutes of aerobic exercise most days

  • Cycle 4: Try to do an hour on the weekends, in addition to a regular regimen throughout the week


The 17 Day Diet relies on a cycled eating plan to help you lose weight. During four cycles, each lasting 17 days (or longer in cycle four), you'll change how many servings of healthy carbohydrates, lean proteins, and healthy fats that you eat each day.

Overall, The 17 Day Diet is a clean-eating plan, with guidance to eat the "right" kind of carbs, meaning white grains and fresh fruits and vegetables, not processed "white foods," like bread, crackers, and cookies. You'll eliminate processed foods, processed sugar, and fried foods; you might balk at the thought of this, but it's guidance that any healthy eating plan is going to provide.

Each of the four cycles has its own objective, whether it be jump starting your fat burn, resetting your metabolism, teaching portion control, or recognizing true hunger. Through this process, you'll actually start to crave the foods that are nourishing your body, like a meal of roasted turkey with asparagus, rather than a burger and fries.

17 Day Diet recipes are available on the Food on the Table Meal Planning App

17 Day Diet Sample Meals

It's fair to want to know exactly what you'll be eating before taking on a new diet. The 17 Day Diet book outlines detailed meal plans for each day of each cycle, so all you have to do is shop and prepare, eliminating the worry and frustration over what you can or cannot eat. The following is a snapshot of what a day of meals look like on each 17 Day Day cycle:

Cycle 1: Accelerate

Goal: Improve digestion, initiate fat burn/discourage fat storage

Rate of Weight Loss*: 5-10% of total body weight; 10-20 pounds

  • Breakfast: Plain low-fat yogurt with fresh berries, green tea
  • Lunch: Green salad with a variety of vegetables like tomato and cucumber with a homemade vinaigrette, green tea
  • Dinner: Grilled salmon, choice of raw or steamed vegetables, green tea
  • Snacks: Sugar-free fruit-flavored yogurt, choice of one fruit

Cycle 2: Activate

Goal: Rest the metabolism, stimulate fat burn

Rate of Weight Loss*: Half of cycle 1; 5-10 pounds

  • Breakfast: Scrambled egg whites, half grapefruit or in-season fruit, green tea
  • Lunch: Baby spinach salad with tomatoes and feta and homemade vinaigrette, green tea
  • Dinner: Grilled turkey patties, side salad, green tea
  • Snacks: Fresh berries, plain low-fat yogurt

Cycle 3: Achieve

Goal: Nurture healthy eating habits, reintroduce more foods, move closer to goal weight

Rate of Weight Loss*: Half of cycle 2; 2.5-5 pounds

  • Breakfast: High-fiber cereal with skim milk, fresh berries, green tea
  • Lunch: Whole-wheat pita with lettuce, tomoato, feta cheese, Italian dressing; baby carrots; green tea
  • Dinner: Barbecued boneless chicken breast, steamed vegetables like asparagus or broccoli, green tea
  • Snacks: choice of one fruit, Skinny Cow ice cream sandwich

Cycle 4: Arrive

Goal: Maintain goal weight

Brunch: Blueberry waffles with syrup, turkey sausage, orange juice Dinner: Grilled chicken breast, steam broccoli, green tea Snacks: Sugar-free fruit-flavored yogurt, raw baby carrots

  • These rates of weight loss were determined during an interview with Dr. Mike Moreno in 2011. This is the amount of weight he says you could safely lose within each cycle. Pounds lost are based on a 200-pound person. The industry standard rate of weight loss is 1-2 pounds per week.

The 17 Day Diet Meal Plan from Bistro MD

If you're short on time or not yet comfortable with your skills in the kitchen, the 17 Day Diet Meal Plan is available from Bistro MD, a leader in the meal delivery space. Each meal follows your progress through each cycle, each day to help keep you in line with the 17 Day Diet guidelines.

17 Day Diet Special Notes

  • The diet is suitable for both type 1 and type 2 diabetics. In an interview with Dr. Mike Moreno in 2011, he noted some type 2 diabetics have used 17 Day Diet and reduced or eliminated their need for medications. For type 1 diabetics, he advises more diligent assessment of sugar levels.

  • The diet is flexible enough to meet the needs of vegetarians. You'll simply modify the protein suggestions, for instance, replacing fish and chicken with soy, dairy, and legumes.

  • Those who don't care for seafood or fish can also alter the diet and replace with the other lean protein of their choice, like turkey, chicken or pork.

  • If green tea doesn't appeal to you, this can also be skipped by replacing with a green tea supplement and/or at least one cup of the tea each day.

The book comes with mostly sound nutritional and fitness guidance and is oulined in such a way that makes it easy, almost effortless, to follow and see results.

One of the best things about this weight loss plan is its design to not only help you lose weight, but set you up for sustainable weight maintenance, which is the true sign of a quality program.

It's availability via a book makes it widely accessible and affordable, so there are no on-going fees, unexpected charges, or recurring needs to re-subscribe. Purchase it once and you could use it for life.

On The 17 Day Diet you'll "re-learn" how to eat, focusing on a balanced diet of lean proteins, whole grains, fresh fruits ad vegetables; and you'll eliminate the junk and processed foods that were no doubt a culprit in your weight and health issues.

Be sure to follow the fitness guidance, as moderate as they may be. If you're comfortable with doing more, speak with a trainer, medical professional, or continue to follow your own tried-and-true regimen of daily physical activity.

On page 40, it states do not eat any fruit after 2pm. On the daily menu plan (pg 48) it tells you to eat fruit as a snack after dinner. So, which is the correct plan?

I love this diet! I have tried SO many things that just didn't work. I have done cycle 1, 2, and 3 and now I am back on cycle 1 day 5. I have lost 29 pounds! I have never lost weight in my life. I used to weigh 210 and now I weigh 181. This is amazing if you stick to it. I hope to loose another 20, but I'm putting in more exercise this time. The first time on cycle 1 and 2 I didn't exercise because I felt faint very easily due to the lack of sugar in my system and wasn't used to eating the way I was but now it doesn't phase me in the least! I find it so much easier to walk now and I am about to go for a swim which I wouldn't be able to do on cycle 1 the first time around because I wasn't used to how my body was reacting. The 17 day diet has taught me how to change my life!

What substitutions for the following foods in 17 Day Diet? I don't care for vinegrette dressing, can I eat the salad without the dressing or without the vinegar? Does the yogurt have to be plain, or can it have sugar? I don't care for a variety of veggies, can I only choose a few?

I have only been on the diet about 3 days. I am a little confused about the yogurt. Can it have sugar in it? And can I add berries to it after 2pm

I tried the 17day jsut like everything else ouyt there. But this worked I have always been somewhat bigger... In high school I was a 13/14 and after years of trying I got down to a 10... 8.... then a 4 - 8. I can say I am thankfull... I am now a size 0-1. I just kept shedding the pounds, I can finally wear a bikini for the first time and not feel like when I wear anything that is form fitting I have to suck in my gut. I am 35 and have a lil one age 7 and a hottie of a hubby.... I have never felt so free, beautiful and sexy ever until now. I can now buy and wear all those cute, figure flattering,belly button showing tee's as well as smaller sized jeans. Best part I am only 5ft so being my height and size now I can buy my clothes in the kids dept or juniors

A buddy lost <75 lb, agreed he had it to lose, but none the less, it was the kick in the pant he needed!

my husband and i began this diet 4 days ago and we love it. we started gaining a few pounds a year after too many food dates and rich dinners and 20 years later it is out of control. we started eating "cleanly" a few years ago, but couldn't lose any weight. my foot was injured in the fall and i gained 15 more lbs "resting" it all winter. i haven't been able to exercise because it is always swollen and painful and never lost weight from exercising anyway. within a day or two the swelling is down considerably and i've lost 9 pounds so far! I just want to shout it from the rooftops. It's working!

Love this diet. Only complaint I have the hic cups often. Strange but ok. Losing weight and it has lowered my blood pressure.

I am a bit of a couch potato and have just finished the first 17 day cycle and lost half a stone! When he says 4oz of brown rice - is that cooked or uncooked weight? Same with porridge - is it cooked in water or milk? It doesn't even say to cook it.... I swore by Weight Watchers but this beats it hands down. I get so excited cooking the interesting and easy recipes, there is so much variety. It's not a diet, it's a lifestyle change and it's working for me.

I just bought the book today and have read up to the end of cycle 1. I have a lot of weight to lose and I want to know if I should stay on cycle 1 for a long time before I go into the other cycles since cycle 4 is for those that have reached their goal weight. Thanks.

Some observations from a guy (me) . . . yes, this diet really does work. I wasn't enormously fat, but just wanted to lose some weight and feel better. I followed the book exactly and actually stayed on Cycle One for 21 days instead of 17 days and lost 20 pounds - it was very easy. Never hungry, never deprived. Unlike Atkins, you get lots of vegetables and fruit (well, "only" two pieces of fruit a day - but that was two more than I was eating before!! lol) - and so it is a very healthy diet. I'm not as strict now, but have found that the following works very well for me: Breakfast - one day fruit and probiotic natural yoghurt mixed together, the next day 2 eggs and half-a-grapefruit. Lunch - big salad with either tuna, turkey or feta cheese cubes (1/4 cup) and lots of vegetables (e.g. peppers, tomatoes, celery, carrot, etc) with a dressing of one Tbs oil and two Tbs vinegar). Dinner: either chicken or fish or turkey with lots of vegetables. A great sauce for the meat by the way is Hot Wing Sauce - no calories, literally, and very tasty. If things get boring, I also cycle in chicken soup into the mix, either for lunch or dinner. I also have two cups of coffee every day and all the water and green tea, as suggested in the original diet. AND, I have a square of dark chocolate every night after dinner, woo hoo! You DO feel better and it DOES work - losing 20 pounds was great and very easy. Good luck.
