  • Established: 2010

  • Founder: Dr. Mike Moreno

  • 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.

  • The "diet" is sustainable

  • 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.

I only did cycle 1 because I reached my goal during the first 17 days. I have been blessed with a body that loses weight fairly easily and my eating habits before starting this diet were terrible. Therefore, maybe it wont work this way for everyone who tries this diet, but it should still be helpful to know it does work. I lost almost a pound a day. I wanted to lose 15 pounds and I lost 16 within the 17 days. It has been a couple months since I stopped the diet and I have maintained my weight loss. I would however like to lose more, and will be starting this diet again.

just started today really excited but.... drinking hot water with lemon is really bad for your teeth will eat the enamel off.

I am in Cycle 2, about half way thru-I started with a 7 pound weight loss goal and I hit it on day 18! Know I am maintaining that weight, which I haven't seen in years! This is the first diet that help me break that plateau!!! Love it!

posted Jul 7th, 2011 10:55 pm


Oh,and forgot to add, my total weight loss in the last 64 days was 18lb! From 186 to 168, with my height being 5'9". I haven't been under 170lb in the last 4 years! Hooray!

I finished my 4th cycle today (did 1,2,3, and 1 again). I lost 6lb! I cheated a lot. Mostly with fruits--eating fruits at night as a snack, or half a watermelon at dinner. And ice cream twice (but just very little each time). I even thought I wouldn't even 'report back' today, and will just stay on the phase 1 for longer, as I've been restarting the cycle in my head several times LOL.

So the 6lb weight loss is pretty amazing in my books, especially as i'm aproaching my goal weight and don't have more than 15 lb to lose now.

I will continue on phase one for another week--no cheating between now and July 14th! Here, I said it publically! LOL

It is my favorite phase, I feel the best on it--no cravings, lots of energy. Then my plan is to do the phase 2, hoping that doing it will prevent me from staing on a plateau, and then back to phase 1.

levern~ grapefruit is just on the list of fruits, you can have any fruit you want on the list and not eat the ones you don't like or can't have. I've never eaten grapefruit on this diet either....gross. ;)

Hey! It's been a while since I have hit the discussion board. How is everything out there in Oklahoma? How are your cycles going on in the diet?

Finished off my first rotation (all three cycles) feeling extremely powerful, down 22lbs. Hoping for this next rotation I can lose around 15-20 lbs as well. Working out 6 days a week and eating very healthy on a new lifestyle plan which definitely is contributing to my weight loss.

Don't forget your daily 8 glasses of water!
Keep me posted!

Is the 17 day diet healthy for the whole family, inculding children? I am considering this diet for myself, and possibly my family. I am looking for a healthy eating lifestyle to put my entire family on, but my husband and children are not in need of losing weight. I only nee to lose about 25 pounds myself. Is this diet safe for the whole family, including children?

posted Jul 6th, 2011 11:34 am


@cece~ you sound a little silly since those are very similar recipese from the 17 day diet. the book just makes it so you don't get bored and re-teaches people to eat correctly. sure it is common sense; what goes in you must burn more. but this is a healthy way to lose more than a lousy 2 pounds per week safely.

If you want to lose weight, all you have to do is stuff yourself with fruits mixed w/Greek yogurt. I buy frozen fish fillets, already cleaned and individually wrapped. I get a piece of foil, put some onions, place 2 filets on top w/a little seasoning, put it in my little cheap toaster oven and that's it. I add a small boiled potato or a little rice with frozen veggies. After eating that, I "close my mouth". For breakfast I have a little oatmeal w/honey and fruit. There are NO miracles, there's NO need to watch funny doctors' shows, NO need to waste your money on yet another temporary guru who comes w/silly menus, with very silly names. Pizza? I get 1 pita bread, cover it w/tomato sauce, a little cheese & veggies and put it in my cheap toaster oven. I don't go to restaurants either, that is the worst.
