Ideal Protein and Phase 1 (Weight Loss Phase)
The Ideal Protein Phase 1 or weight loss phase is where the dieters lose most of their weight. Generally, Phase 1 lasts until 100% weight loss goal is achieved.
Phase 1 was designed to maximize fat loss through nutritional ketosis – a safe and natural metabolic state. Here, the body switches its primary fuel source from simple and complex carbohydrates to ketone bodies (energy molecules produced by burning stored fat in the body).
As one enters phase 1, nutritional ketosis is achieved by restricting carbohydrates (sugar) and calories. This, in turn, compels the body to switch to fat/fatty acids as an alternative source of energy, which has greater calorific values and provides enough energy to meet the body’s daily needs.
Depending on the starting weight, you can expect to consume between 3–5 partial meal replacements daily on Ideal Protein phase 1, including 4–8 ounces of allowed whole proteins.
As carbohydrates are limited in Ideal Protein phase 1, the sugar level in your blood is lowered. As a result, your pancreas is relieved as it can go back to producing normal levels of insulin – returning insulin balance to the body.
In this article, we will take a look at
Ideal Protein Food List - Allowed and Restricted Foods in Phase 1
Ideal Protein has a saying for the Phase 1 food list – they say “eat the sheet”, meaning if it’s not on the sheet, it can’t be included in the diet.
Hence, our coaches focus dieters who want to lose weight fast on sticking to the serving size requirements, food group choices, and staying in ketosis to lose weight faster on Ideal Protein.
We encourage clients to create variety in the Ideal Protein recipes while they are on Phase 1 to keep their weight loss diet exciting.
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”.
Remember to weigh your protein before cooking your recipe.
Raw Vegetables & Lettuces - Unlimited
Dietary fiber is excellent to ward off hunger and stabilize your blood sugar. The vegetables and lettuces below are “free” items.

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

What Makes Ideal Protein Products Special
Ideal Protein products are more than just packaged diet food. It sets itself apart from other partial meal replacement diets because of the bioavailability of nutrients and their design for taste and function.
Additionally, Ideal Protein products do not contain any Genetically Modified Organisms (GMO’s), dangerous trans fats, harmful preservatives like Monosodium Glutamate (MSG), or toxic, high-glycemic sweeteners like aspartame.
The Ideal Protein products are ranked on the chemical index for bioavailability and are between 96% – 297% bioavailable. What does this mean?
It means you obtain all of the nutrients for a fraction of the calories, allowing your body to metabolize and assimilate these vital nutrients easily.
Note that digestion of whole foods, such as eating a steak, you consume 100% of the calories but only 70% of the nutrients from what you are eating.
Ideal Protein Products Include Prebiotic Fiber
In addition to the benefits of maximizing absorption, Ideal Protein’s product line has evolved in line with modern nutritional trends. Ideal Protein foods list has integrated products that are sweetened with nutritive sweeteners, such as stevia and also prebiotic fiber.
Prebiotic fibers support both optimal nutrients for the dieter and the microbiome.
Most people have heard a lot about the connections between probiotics (foods that enhance your good bacterial colonies in your intestinal tract) and health, mood, and weight but many aren’t familiar with prebiotics.
Prebiotics, on the other hand, provide the ideal environment and nutritional sources to feed your good bacteria.
Prebiotics are a great fit for the Ideal Protein protocol because while they are technically carbohydrates, they are filled with fiber and non-digestible carbohydrates.
This fiber provides satiety to the dieter while feeding the good bacteria, helping it to flourish in the gut. In fact, several studies demonstrate that prebiotics play a more significant role in weight loss when compared to probiotics.
Prebiotic fiber can help absorb intestinal fat, supporting weight loss. Additionally, prebiotic fiber can slow the absorption of calories into the bloodstream.
Lastly, while prebiotic fiber provides sweetness, it does so without creating a glycemic impact, fitting in perfectly with the low carb, low GI ketogenic diet approach. These products support the whole-body health approach of the diet as well as creating appetizing, satiating yummy renditions of old favorites.
Two Categories of Ideal Protein Products: Restricted & Non-Restricted
Due to the low carb nature of Ideal Protein Phase 1 diet, dieters are recommended to monitor their net carbohydrates while on this phase. During Phase 1, dieters are recommended to aim between 25-45 grams of net carbohydrates per day.
The whole food lists of Ideal Protein diet can be broken into 2 categories – restricted and unrestricted (or non-restricted) foods.
To explain, Ideal Protein distinguishes between the two based on net carbohydrate content of the foods. Unrestricted Ideal Protein Products have 7 or fewer grams of net carbohydrates. On the other hand, products that are considered restricted in the diet have 8 or more grams of net carbohydrates.
To help you stay in ketosis, the diet limits you to 1 restricted item per day.
Restricted snacks included in Ideal Protein food list used to be all bars, chips, and treats. However, it has evolved and now very few of those items, except the bars, are restricted.

The New Ideal Protein Phase 1 - Changes Made in 2020
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.
It’s important to note, in December 2019, Ideal Protein refined this successful protocol to make losing weight even easier. If you are researching Ideal Protein, make sure you are looking at the latest version of Ideal Protein. Here are the changes that took effect at the beginning of 2020:
Typical Ideal Protein Phase 1 Menu
Initially, the Ideal Protein protocol consisted of 4 phases, with Phase 1 being the step where you would lose most of the weight. Ideal Protein has simplified its 4 – phase protocol to 3 phases.:
Additionally, Ideal Protein launched a revised recommended Phase 1 diet menu as well as reformed its guidelines.
Along with consolidating Phases 3 & 4 to a new Phase 3 diet, Ideal Protein added new Ideal Protein products, more foods to the allowed foods list. Allowed whole food protein on Phase 1 is now reduced from 8 ounces to 4 to 6 ounces per meal. As a result, now you can lose weight faster, enjoy your weight loss journey, and transition faster with Ideal Protein.

A Few Basic Questions and Answers About Ideal Protein Phase 1
How Long Does Ideal Protein Phase 1 Last?

What Foods Do I Need to Avoid in Phase 1?
Anything outside the sheet! Download the Ideal Protein food list sheet here.
Can I Workout During Phase 1?
Yes. But keep it to a certain extent.
We encourage light exercise After the first 2 weeks on the protocol. As Phase 1 limits calorie intake, heavy exercise may lead to muscle loss.
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.
What’s Different About Ideal Protein?
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 removes 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 as it 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 Ideal Protein utilizes the tenets of a ketogenic diet while integrating education and support for creating a healthy lifestyle after the diet is over.
What is the Alternative Plan?
The Ideal Protein Alternative Plan is similar to the actual protocol in many ways, but it allows a lot more variety. Like the protocol, the Alternative Plan has 3 phases. Dieters may add up to 3 more foods per day, one from each of the three food groups carbohydrates (Group I), fruit (Group II), and fats (Group III) – as shown in the images below:
Because of these additional foods, weight loss on this modified version occurs at a slower rate compared to the protocol, but the dieter is less likely to experience cravings. Those who wish to go on the Alternative Plan should also keep in mind that regaining lost weight is more likely with this plan than the Ideal Protein protocol, as the body is not kept in a state of ketosis. The Alternative Plan is recommended for some Type I diabetic patients.
