The 17-day diet was introduced by Dr. Mike Moreno when he published his book in 2010. The important thing about this diet is regularly changing foods and calorie consumption, which is claimed to promote metabolism.
The 17-day diet is classified into 4 cycles such as Accelerate, Activate, Achieve, and Arrive. The first 3 cycles remain 17 days each, while the arrival cycle is followed for life. As you move from the cycles, the diet includes strategies and food options.
This diet will not tell you how many calories you need during each cycle.
However, it progressively raises calorie consumption by introducing extra calorie-containing food for each cycle.
In 2014, Dr. Moreno published a breakthrough edition of the diet with some additions:
17 Day Diet: 4 cycles
Cycle 1: Accelerate
The Accelerate cycle is the 1st cycle of the 17-day diet. It challenges to help you to drop 10-12 pounds that 4.5-5.4 kg during the first 17 days by:

- lowering refined carbs, sugar, and sweets.
- Clearing toxins from the body that affect metabolism.
During this time, you are allowed to consume limitless vegetables and vegetable options from the particular Accelerate foods list. Most carb-rich foods are not allowed during this cycle.
However, fruits are an exception even you are not allowed to consume any fruit after 2 pm. The book claims that it is difficult to burn carbs later in the day as you remain less active. Other guidelines include:

- Eat slow and chew food until you feel your stomach full.

To follow this cycle, spend 1 day on the accelerated diet plan, the next day on the activate plan. Keep alternating between these 2 versions over the next 17 days.

Is It Useful for Weight Loss?
As this diet plan restricts calories, it effectively helps for quick weight loss, which means it can create a calorie deficit.
Eating fewer calories than your body burns is a sure-fire way to reduce weight. For example, during the accelerated cycle, the 17-day diet reduces your lean protein choices, probiotic foods, and no starchy vegetables, which are low-calorie.
During the activate phase, it implements a modified take on change day fasting, which has been discovered to be effective for fat loss, as people feel it easy to follow.
Still, though the diet can help weight loss, it makes different weight-loss claims that are not supported by evidence, like the change in food groups and calorie consumption can confuse and promote metabolism.
It also suggested skipping carbs after 2 pm, claiming that carbs consumed later in the day are difficult for your body to burn, as you burn low energy in the evening. However, there is no high-quality research that supports this claim.
All told, the 17-day diet can benefit to lose weight, but evidence to suggest that is extra effective than conventional, whole foods, and calorie-restricted diets are not sufficient.

Pros and Cons
Though some experts state that proof for the 17-day diet is lacking, Dr. Moreno’s website says that there is some science after it.
Here are the pros and cons of a 17-day calorie diet.
Lean protein and Lots of veggies
The 17-day diet cycle has plenty of healthy lean protein and non-starchy vegetables. You are allowed to have limitless both in all phases of the diet. These should benefit to stop hunger in the initial days of the diet.
Adaptable to dietary limitations
If you have a celiac ailment, a nut allergy, dairy intolerance, you can easily change the program to meet your requirement. Food choices are costly enough that you can clear about allergenic things and still follow the diet.
Weight Loss Is Likely
You are almost sure to lose weight, particularly in the initial days of the diet, because your calories will be less, even though you have unlimited lean protein with starchless vegetables. Initial weight loss can promote motivation and help to track your progress.
Not enough fiber
Everyone needs fiber like women to need 22-28 gm and men need 28-34 gm every day. If you are not careful with planning meals out in the first cycle, you could fall out of your fiber need. Make sure to combine more nonstarchy vegetables and two servings of high fiber fruits every day to meet your everyday requirements.
Confusing to follow
The first phase of the 17-day diet can be hard to understand as it has fewer special rules and other food limitations. However, the later stages seem to be extra balanced. Some people may see it as more time-consuming to prepare and make meals ready, however, the recipes are very simple.
17-Day Diet: Is it a Healthy Choice?
The first cycle of the plan reduces certain food groups such as fruits, and whole grains, but these foods are included back over time. Therefore, the first cycle of the diet does not follow the USDA’s dietary guidelines, but as you keep following the plan, the diet becomes more balanced.
The nutritional guidelines from USDA’s MyPlate that fill more than one quarter oof plate with grains, commonly with whole grains.
The 17-day diet does not allow any grains in the first cycle and after that only permits less grain-based product.
The USDA likewise informs a decrease of 500 calories per day for a consistent pace of weight loss.5 On a 2,000-calorie diet that would mean taking in around 1,500 calories each day, yet this can fluctuate depending on various elements like age, sex, weight, and level of active work. Utilize this calculator to help decide your own calorie rules to meet your objectives.
How does 17 Day Diet work?
According to Michael Rafael Moreno’s 2011 book, this diet is designed for rapid weight loss. The plan claims to reduce pounds quickly and permanently. The diet is separated into three 17-day cycles to stop boredom and your body from plateauing, says Moreno, a family from California medicine physician.
During the first Accelerate cycle, you will cut around 1200 calories every day, lower sugar consumption, and focus on digestion improvement. It is when you will reduce the most 10-15 pounds-though most of it will be water weight.
After 17 days you will reach the 2nd cycle, Activate. During this time, you will change between the diet of a limited calorie or accelerate and activate a light higher calorie meal plan.
This back-and-forth restores your metabolism and energizes fat burning to yield an extra deficiency of 5-6 pounds. In the third cycle, “Achieve,” you’ll center around growing great dietary patterns to drop another 2-3 pounds. The last cycle, “Show up,” is continuous. You’ll keep up your objective load by eating invigoratingly on non-weekend days and making the most of your number one food source (with some restraint) at the ends of the week.
You can develop your meal plans using Moreno’s lists of acceptable non-starchy vegetables, lean proteins, low sugar fruits, and natural carbohydrates, which include some common portion guidelines. Green tea in this diet works wonders for blocking fatty tissue.
Moreno also provides tips for dieting on the road, at restaurants, during the holidays, for various cultural cuisines, and if you are PMS.
How much does 17-Day Diet cost?
You will be purchasing more fresh produce, meat, fish, so this diet could get expensive. But you can buy where you wish and organic foods are not needed.
Is the 17-day diet easy to follow?
Sticking to the 17-day diet is feasible.
It is relatively convenient: Moreno offers tailored meal plans for busy work schedules, and holidays for example. But the diet requires significant food prep and shopping, which are time-consuming.
Moreno provides recipes on his website and his book back, but you can use your own and they conform to his guidelines.
Eating out in this diet is allowed but avoid fattening restaurants.
You are allowed to drink one every day during the last 2 cycles, but you are strongly recommended to skip when you can.
Your meal should prevent hunger, but not make you feel stuffed or full. Many items do not with strict sizes of portion, so you can consume till you get satisfied.
How many exercises You Should Do On A 17-Day Diet?
Workout is an important component of the 17-day diet. During the 1st and 2nd cycles, you will spend 17 minutes every day doing some light workout like walking. During the 3rd cycle, you will do 40-60 minutes of aerobic workout most days of the week. In the last cycle, you will work out for one hour on weekends and continues with regular plans on weekdays.
The 17-Day Diet: Effects of Short-Term and Long-Term
The 17-day diet may have short-term effects, so if you have to reduce some pounds for an event, a diet like this could be effective for you. Keeping the weight off for the long term, however, might be problematic. One can not stay like this for more time because of too many rules. You will also find it difficult to manage food. Therefore, it is suitable for short-term diet plans.

Good dieting is about learning your health, shopping for suitable food, cooking for yourself, and eating.
