In this guide, we’ll break down what the 17 Day Diet is, how the xxwww-20 version relates to it, and how you can use it to achieve your weight goals.

What Is the 17 Day Diet?

The 17 Day Diet is a weight loss plan created by Dr. Mike Moreno. It’s based on the concept of shifting your calorie intake and food groups in 17-day cycles to keep your metabolism active and prevent plateaus. The goal is to lose weight quickly in the early stages while gradually reintroducing more food variety for long-term sustainability.

There are four key phases:

  1. Accelerate – The first 17 days focus on rapid weight loss through low-carb, high-protein meals.

  2. Activate – Introduces calorie cycling to prevent plateaus and boost metabolism.

  3. Achieve – Adds more variety, including whole grains, fruits, and healthy fats.

  4. Arrive – The maintenance phase helps you develop habits to keep the weight off for good.

Each phase lasts 17 days, which makes the full program 68 days in total. However, most people notice results within the first two weeks.

How Does the 17 Day Diet Help You Lose Weight?

This diet is designed to work with your body’s natural metabolism. Here’s why it’s effective:

  • Frequent changes in food types and calories prevent metabolic slowdown.

  • Low-carb intake in Phase 1 helps reduce water retention and bloating.

  • Healthy fats and proteins promote satiety, so you’re less likely to overeat.

  • Regular movement and hydration are encouraged throughout the plan.

The idea is to trick your body into burning fat efficiently while establishing better eating habits—without feeling deprived or overly restricted.

Foods to Eat on the 17 Day Diet

Here remain the types of foods allowed during each phase of the plan:

Accelerate:

  • Lean proteins (chicken, turkey, eggs, fish)

  • Non-starchy vegetables (broccoli, spinach, cauliflower)

  • Probiotic-rich foods (Greek yogurt, kefir)

  • Green tea and lots of water

Activate:

  • Everything from Phase 1

  • Natural starches (brown rice, sweet potatoes, oats) on alternating days

Achieve:

  • All previous foods

  • Healthy fats (olive oil, avocado, nuts)

  • Additional fruits and grains

Arrive:

  • Flexible meals with the 80/20 rule (eat clean 80% of the time, indulge 20%)

These phases help reduce calorie intake without feeling like a crash diet.

Exercise Recommendations

The 17 Day Diet includes daily movement as a key part of the plan. In the early phases, light activities like walking or yoga remain recommended. As your body adjusts, you can add in strength training or higher-intensity cardio.

Regular exercise helps speed up fat loss, tone muscles, and improve your energy levels throughout the program.
