1. Theory Of The 17-Day Diet Weight Loss Plan

We all know that our body is forever at war with new changes. The 17-day weight loss diet plan uses this theory and puts it to practical use. The diet plan prescribes different eating and exercising regimens, which vary each of its four phases. This keeps the body from adjusting to the diet. Just about the time your body adapts to a particular eating and exercising pattern, a change is introduced. This keeps your metabolism high. Though this plan has not been scientifically proven, many people have benefited from this balanced diet.

2. How Does The Plan Work?

The 17-day diet plan is a tried and tested doctor’s plan that has been specifically designed for rapid results. This plan is structured in such a way that you not only shed pounds really quick but also do not regain those lost pounds. This means you lose weight, and it is more or less permanent. What a godsend!

The diet is divided into three 17-day cycles that coax your body to shed all those pounds you piled on from eating junk food and living a sedentary lifestyle. The three cycles also prevent your body from plateauing, which is the most common problem faced by most dieters.

3. The 17-Day Diet Plan

Since you want to lose weight without starving yourself or depriving your body of nutrition, we show you how to go about it, step by step:

Back To TOC

Phase 1: Accelerate

The first phase is named Accelerate, where you will need to cut out about 1200 calories a day, drastically reduce your sugar intake, and shift your focus towards improving your body’s digestion. This phase sees the maximum weight loss, though this will mostly be water weight.

Foods To Consume

  • Lean proteins such as fish and chicken breast and turkey (as much as you want to consume)
  • A generous serving of non-starchy vegetables such as capsicum, broccoli, celery, cauliflower, garlic, cucumber, lettuce, leeks, spinach, tomato, onion, okra, artichoke, and parsley.
  • 2 low-sugar fruits such as apples, berries, oranges, prunes, and plums.
  • Low-fat yogurt – 2 cups
  • 2 whole servings of any friendly fats
  • 2 liters of water
  • 2-3 cups of green tea

Phase 2: Activate

Now it’s time for phase two – Activate. During this period, you will need to alternate the Accelerate phase low-calorie diet with a slightly high-calorie diet. Alternating the two meal plans will reset your metabolism that, in turn, will stimulate the burning of fat. This phase sees a loss of a minimum six pounds.

Foods To Consume

In this phase, you can alternate the above-mentioned meal plan with a slightly higher calorie meal. You can have fish, chicken breast, shrimp, oysters, scallops, lean cuts of meat, whey protein, yogurt, barley, brown rice, oat bran, couscous, chickpeas, millets, kidney beans, lentils, soybeans, potato, butternut squash, and cassava root.

Phase 3: Achieve

Time to achieve! Yes, the third phase is aptly called the Achieve phase, where you shift your focus to midday snacking and binging on junk food. Time to say goodbye to both, and hello to good eating habits. You will see a drop of another three pounds during this phase.

Foods To Consume

This phase allows the addition of healthier food options that will help you achieve healthy eating habits. You can eat quail, Canadian bacon, turkey, chicken, brown bread, oats, low-carb tortillas, rice noodles, wheat noodles, zucchini, wax beans, cilantro, chilies, banana, apricot, low-fat cottage cheese, soy milk, almond milk, figs, tangerine, kiwi, papaya, pineapple, cherry, mango, guava, canola oil, low-calorie margarines, and 5 oz. wine. You should avoid eating fatty meat, processed meat, and white flour. AAlso, avoid drinking fresh fruit juice after 2 pm.

Phase 4: Arrive

The last cycle is termed as Arrive, and it is an ongoing cycle where you monitor your eating habits and maintain your weight.

The beauty of this diet plan is that it does not ask you to steer clear of food you like. Instead, it suggests that you follow a healthy meal plan through the week, and allow yourself treats during the weekend.

Exercise is vital in the 17-day diet plan. During phases 1 and 2, you need to spend a good 20 minutes every day doing light exercises like walking. During phase 3, shift to 40-60 minutes of aerobic exercising on all days of the week. If you have a cycle, there is no better exercise than cycling at a moderate 12-14 mph every day for an hour. In the last phase, you can taper down your exercising to half an hour during weekdays and an hour on weekends to maintain a healthy weight.

Foods To Consume

By this time, you have achieved your weight goal, and it’s time to just maintain the new you. What do you consume here? More or less what you did in cycle 1 along with one serving of food that has a higher calorific value. Stick to this diet during the weekdays, and relax and take it easy on weekends and enjoy the food you love most. However, avoid foods that are high in fat, carbs, and sugar content.

4. Vegetarian Modifications

Include tofu, whey protein, nuts, corn, hemp seed, rice, and beans in your diet.

5. What Is The Science Of The 17-Day Diet?

  • Low Sugar

The 17-day diet does not contain added sugar but contains natural sugar from fresh fruits. If you want to lose weight, it is extremely important to take less sugar. If you take more sugar, your insulin levels will rise. Insulin inhibits the burning of fat in the body. Therefore, if you keep the insulin levels in check, you will burn fat rather than accumulating it.

  • High Protein

Proteins are the building blocks of our body. When you eat a protein-rich diet, you provide your body the energy it requires to perform various functions throughout the day. Proteins (enzymes) help in metabolism and in burning calories. A protein-rich diet makes you feel full, which is why you will feel less tempted to munch on crisps.

  • High Fiber

Vegetables that are high in fiber have fewer calories. Since veggies contain almost all the nutrients that our body needs, you tend to feel full. Fiber present in the vegetables positively regulates metabolism, supports the digestive system, and helps you to get rid of the water weight.

  • Low-calorie Diet

When you have a low-calorie diet for a certain period, your body gets used to it. Since you are having high fiber diet, you keep those carb and sugar cravings at bay. Cut yourself out from starchy food, and eat fewer carbs and sugar.

The best part of the 17-day diet is that you don’t starve or bore yourself. Eating right and in the right amount is the key to losing weight.

Experts all over the world advise against going on a crash diet.

Any kind of exercise, such as jogging, power walking, aerobics, swimming, kickboxing, Zumba, and cycling, will aid in quicker weight loss. If you eat fewer calories, your body will have to burn the stored fat to get the energy for performing any kind of workout. Working out regularly will make you look and feel better. You will feel rekindled and energetic, and you would want to workout more.

Here is the exercise routine you should follow depending on which phase you are in:

  • Phase 1 – 15-20 minutes walking
  • Phase 2 – 15-20 minutes jogging
  • Phase 3 – 45-60 minutes Zumba, aerobics, or kickboxing
  • Phase 4 – 45-60 minutes of your favorite exercise plus workout on weekends
