17 Day Diet Review

What is it?

The 17 Day Diet is a diet plan for people who are looking for a low carbohydrate, 4 phase approach to weight loss. It focuses on providing fat-burning benefits, healthier eating habits, and unique food patterns to have your metabolism guessing.

Dr. Mike Moreno created it, and he claims in 17 days you’ll be able to lose between 10 to 12 pounds. It does take some limitations on what you can eat, but the diet promises long lasting results that stick as long as you eat in moderation. The program promises to provide:

  • Different cycles of eating: Depending on what day of the diet you’re on, the kinds of foods will change. This is meant to help confuse the body, which in turn makes it easier to burn fat. There are also certain exercises for each phase.

All this is said to come together to allow for the ultimate fat loss experience.

  • Many recipes: You can create your own recipes, but the plan also offers many recipes tailor made for this diet. There’s also free recipes on the official website, though more comprehensive results are available if you purchase the book.  
  • Exercise tips: There’s even a 17 minute exercise routine that provides weight lifting, and cardio workouts. You do have to make sure you exercise in order for there to be sufficient fat burning.

Depending on what part of the cycle you’re in, the amount of exercise can also vary. The last phases require the most activity.

  • Apps and additional features: An app made specifically for dieters on this plan is offered. There’s also additional support system that you can also pay for. The website also offers a month to month service with additional videos to help you while on the diet.

The idea of confusing the body by changing what you eat has been used by some diets. The difference is that the 17 Day Diet is claimed to be a cutting edge scientific plan, which has been proven to work.

In this review you’ll learn all about what this diet can truly offer.

 Foods Allowed by the Diet

The foods you can eat depend on what phase of the cycle you’re on. The cycles are described as:

Cycle 1 Accelerate: Low carbohydrates are allowed, and high protein is emphasized. They mention that this is:

“arguably the hardest part of the diet”

 This phase is used to increase the speed of fat loss, while cleansing the body.

You’re allowed an extremely limited amount of carbohydrates only before 2pm. Also, no starchy carbohydrates are allowed at all. So you can’t eat things like potatoes, breads, rice or pasta.

2 servings of probiotics are suggested each day as well.

The total caloric limit is just 1,200 calories a day. This can be extremely hard and that is’ why it’s considered the hardest part of this diet.

 Cycle 2 Activate: Your metabolism is reset to allow for enhanced fat burning. You’re now allowed a slow introduction of more carbohydrates as well as fats.

You’ll be eating more oily fish and red meat. Also, you can eat potatoes, yams, beans, lentil’s quinoa, and brown rice. Though it’s still limited, and you still can’t eat any carbohydrates after 2pm.

 Cycle 3 Achieve: On this stage your goal is to improve your overall eating habits. You’ll learn how to properly eat carbohydrates. It combines elements of the past 2 cycles.

You can eat fats such as avocado, olive oil, mayonnaise, and you can also snack occasionally.

You also get one alcoholic drink a day in the form of one serving size.

 Cycle 4 Arrive: You maintain what you’ve earned. You can have the occasional relaxed weekend where you eat more of the foods you enjoy. It’s mentioned that you’ll be able to

“enjoy just about anything you like”

 Though they do not make it clear on what this means exactly.

For all stages it’s advised to drink at least eight tall glasses of water. This is for proper hydration, and to boost fat burning.

Each phase also has recommended exercises. For the first two cycles it’s advised to walk 17 minutes a day. Cycle 3 requires 40 to 60 minutes of aerobic exercise at last 4 times a week. Cycle 4 advises the same as cycle 3, but with 1 extra hour for the weekends.

 How Does the Diet Work?

 By challenging your metabolism, you allow for maximum fat burning. There are certain foods that must be avoided during certain periods. Also, exercise has to be introduced for even more fat burning.

The idea is simple, but it has yet to be proven. Though it would be beneficial to exercise as much as the diet requires, the fact that there are windows for certain foods for extra fat burning has not been the case for all users.

Customers have had the following to say:

“I gained back every pound I had carefully lost:

“couldn’t make it past a couple of days because of how hungry I was”

 “similar to common sense previous diets”

 “pretty much the same as the Atkins or South Bean diets”

 For many the diet didn’t introduce any new ideas that aren’t already known. It focuses a lot on natural foods and exercise, which his healthy.

However, the timeframe for certain foods has yet to be a proven approach to weight loss.

Many people who used this diet didn’t think it was informative enough to help people sustain weight loss. There was the average opinion that getting started was extremely difficult.

Though the 17 Day Diet admits it’s hard to get settled in, there’s no help provided to help one move past the initial hunger.


  • Several books featuring the ideas behind this diet have been published in different books.
  • The diet emphasizes getting lots of water, exercising, and eating whole foods. These are all known healthy tips for weight loss.
  • You can also use a special app made especially for dieters using this program.
  • You’re allowed to eventually eat the foods you like, as long as it’s in moderation.
  • There are also specific recipes for each of the 4 cycles you go on.


  • No proof is provided to suggest that metabolism has certain windows in which it can be confused. No clinical studies are provided by the diet to help prove this claim.
  • A lot of the health tips are common sense. Many customers felt they didn’t learn anything new from this diet that other plans haven’t already covered.
  • It’s likely that the weight lost initially is all water weight, and not fat. This is why many who reintroduced carbohydrates quickly regained all the weight they lost.
  • The creator of this diet does not specialize in nutrition or weight loss.
  • Many customers have complained that weight loss is not possible, and that the diet is incredibly limiting. Some mentioned they felt as if they were starving. 

Better Alternatives to the Diet

 Though a lot of the tips offered are effective, many of these ideas are common sense. The idea of having to eat less salt, processed foods, and increase exercise is all well known.

Another problem with this diet is that it promise between 10 to 12 pounds of weight loss. While this seems impressive to happen in just 17 days, it’s possible this is all water weight and not fat.

According to Live

 “Low-carb diets help you shed pounds rapidly in the first few weeks, but you aren’t magically dropping fat”

 “causes your body to lose excess water weight naturally”

 Therefore, this diet might bring the illusion of weight loss. This is why many users of the diet claim that the weight came piling back on as soon as they reintroduced carbohydrates.

8 fit also adds:

“each gram of Glycogen bound to 3-4 hefty grams of water”

 Glycogen is what the body transforms carbohydrates into.

So it’s possible to lose up to 20 pounds of just pure water weight. What ends up happening as soon as you introduce more carbohydrates is that you regain this weight.

This is likely why the diet advises you to limit your sodium intake. Sodium as well can make the body hold unto water weight.

It would have been useful to see the science behind this diet. There are no links or scientific studies that show that you will lose fat.

The initial limitation of calories can help with weight loss, but it’s not a long-term solution. This might be why the diet has been limited to a 17 day period.


 Due to the limited amount of calories allowed for the first 2 cycles as well as the lack of carbohydrates, it’s possible to lose some weight. Though it’s likely most of this will be simply water weight.

The issue is whether or not there are long term results. By limited calories for a short period you’re likely to have some results, but keeping this going can be impossible for some. Also, limiting carbohydrates will also get rid of water weight only. This is seen in the many people who tried this diet and failed to keep their weight loss.

Once you reintroduce carbohydrates you will regain all the water weight you lost. However, since it’s not fat and simply water weight, any diet can cause this change. There’s nothing unique in the 17 Day Diet to suggest it would be useful for real long lasting weight loss benefits.

Much better solutions are available for helping you shed pounds that aren’t as restrictive and demanding.
