Ideal Protein Phase 1 Food List & Complete Diet Guide

Ideal Protein Phase 1 or Weight Loss Phase is where you would lose most of the weight.

While the keto diet craze is a recent phenomenon, the Ideal Protein Protocol was created almost 30 years ago by Dr. Tran Tien Chanh and Olivier Benloulou. Dr. Chanh, a French physician, was looking to create a safer and easier weight loss protocol for his patients. At the time, his focus was on athletes needing to drop weight quickly but maintain function and performance.

Initially, the Ideal Protein protocol consisted of 4 phases with Phase 1 being the step where you would lose most of the weight. There have been a few changes in the last few years. Now, you will go through 3 phases of the Ideal Protein protocol:

  • Phase 1 or weight loss phase
  • Phase 2 or stabilization phase and lastly
  • Phase 3 or maintenance phase

This article will give you an insight into Phase 1 of the Ideal Protein diet. We will also look into the Ideal Protein allowed food list, Ideal Protein supplements, Ideal Protein Phase 1 recipes, and more.

Ideal Protein Complete Food List for Phase 1

We encourage dieters to create food variety while they are on Ideal Protein Phase 1 to keep their weight loss diet exciting.

Ideal Protein restructured the protocol in 2020 for faster and more effective weight loss results and introduced new products and expanded the allowed foods list. With so many options, you’ll never have to eat the same thing repeatedly.

While there is no frying or breading permitted, you can use an air fryer and also use your Ideal Protein foods, such as the chips, to create “breading”.

Ideal Protein has also reduced the allowance for whole protein allowed on Phase 1 from 8 ounces to 4 to 6 ounces. As a result, now you can lose weight faster, enjoy your weight loss journey and transition faster.

Remember to weigh your protein before cooking your recipe.

Whole Protein Sources in Ideal Protein Diet Phase 1

Whole Protein Sources Allowed in Phase 1

At the time, the ketogenic diet was relatively unheard of, outside of the Atkins diet which was gaining popularity. Similar to the Atkins diet, Ideal Protein also takes out simple and complex carbohydrates from the diet to put your body into ketosis, a biochemical state that forces the body to burn stored fat rather than the carbohydrates you consume.

What makes Ideal protein different from Atkins and modern-day Keto is that it’s a modified approach that temporarily restricts fat consumption during Phase 1 to refocus the body on burning stored fat rather than the fat you consume.

Another important distinction is that Ideal Protein utilizes the tenets of a ketogenic diet while integrating education and support for creating a healthy lifestyle after the diet is over.

Supplements to be Taken in Ideal Protein Diet Phase 1 

Micronutrients are vital ingredients necessary to support your body and its functions.

From maintaining muscle mass, energy production, and retaining hydration. Being on a diet does not decrease these demands.

For that reason, Ideal Protein Phase 1 requires a few mandatory supplements to provide all nutrients typically found in the foods that you will be restricting on the Ideal Protein protocol. The addition helps you achieve the minimum recommended daily allowance (RDA) of vitamins and minerals. It’s a vital step and skipping it can actually slow your progress, costing you more in the long run.

  • IP Multi-Vita: 2 capsules daily
  • IP Potassium: 1 tablet daily
  • IP Cal-Mag: 2 tablets twice daily with meals
  • IP Omega-3 Plus: 1 capsule twice daily with meals
  • IP Anti-Oxy:

    • Why it is recommended: Antioxidants are
      chemical nutrients that support the body in
      combating the dangers of oxidative stress.
      Antioxidants can protect against free
      radicals and potentially even reverse the
      damage.
    • Recommended dose: 2 capsules daily
  • BCAA:

    • Why it’s recommended: Ideal Protein’s BCAA’s can speed up your results because they help you maintain muscle mass while you are losing weight. Especially important for those who exercise on Ideal Protein Phase 1 and also for those who lose too much lean mass.
    • Ideal Protein BCAA recommended dose:
      • Phase I & 2:
        • General recommendation: 1 packet per day during the first 3 weeks.
        • If losing too much lean mass after week 3: 1 packet per day
        • If exercising on Phase I: 1–2 packets per day. You need to take them 30 minutes before your workout and you can have another one after, but the pre-workout dose is vital and timing is key.
      • Phase 3:
        • Great pre- and post-workout supplement to support your training, energy levels, fat burning, and it even acts as an appetite suppressant.
  • IP Digestive Enzymes:

    • Why it is recommended: Aids in the digestion of whole foods. It breaks down larger food molecules into smaller particles that can more readily be absorbed.
    • Recommended dose: 1–2 capsules with meals.
  • IP Flora Health:

    • Why it is recommended: Probiotics promote normal bowel habits and assist in the digestion and absorption of nutrients in the body.
    • Recommended dose: 1 capsule daily.

  • May reduce heart disease risk factors
  • Improve PCOS related issues
  • Improve acne

What Side Effects I May Experience During Phase 1?

Ideal Protein phase 1 restricts your usual calorie intake (especially carbohydrates). As a result, you may experience some of the following discomforts in the beginning days:

  • Hunger (although you can eat unlimited vegetables)
  • Headaches (due to reduced sugar intake)
  • Bad breath or Keto breath
  • Increased thirst
  • Nausea
  • Dizziness
  • Fatigue
  • Mild constipation
  • Hair thinning/ hair loss
  • Irregular menstrual cycle

Can I Workout During Phase 1?

Yes. But keep it low-intensity. We rather encourage light exercise only after the first 2 weeks on the protocol.

Ideal Protein is considered a low-calorie plan and Phase 1 is the stage where calorie intake is significantly reduced. Thus moderate to heavy exercise may lead to loss of lean muscle which contradicts the goal of the program. 

Exercises such as body movements, light stretching, and gentle yoga are excellent options to go with. You can also follow the fitness program available on the IdealSmart app. 

However, please keep a few things in mind when exercising:

  • Do not get overly tired
  • Supplements are a must!
  • Keep well hydrated. You must increase your water intake if exercising.

Can Vegetarians or Vegans Follow the Ideal Protein?

Vegetarians can follow the Ideal Protein Weight Loss Protocol and can consume eggs, fish (if Pescatarian), or tofu during their evening meal for their whole protein. As an alternative, they can also have 2 Ideal Protein foods for dinner in replacement of their whole protein. Ensure you review the ingredient list on all boxes before purchasing them.

Strict vegans, who do not consume any animal proteins and animal by-products, such as dairy products, honey, and so on, do not qualify to follow the Ideal Protein Weight Loss Protocol due to the many dietary restrictions.

How Ideal Protein Makes a Difference?

Ideal Protein also takes out simple and complex carbohydrates from the diet to put your body into ketosis, a biochemical state that forces the body to burn stored fat rather than the carbohydrates you consume.

What makes Ideal protein different from modern-day Keto is that it’s a modified approach that temporarily restricts fat consumption during Phase 1 to refocus the body on burning stored fat rather than the fat you consume.

Another important distinction is that Ideal Protein utilizes the tenets of a ketogenic diet while integrating education and support for creating a healthy lifestyle after the diet is over. Owing to its genius strategy, you will lose fats fast and keep it off in the long run.
