What is the key Principle of Jillian Michaels Diet?

Jillian Michaels performed experiments in 2 groups of obese people to analyze the rate of weight loss, and she trained obese individuals from one group.

Then, she incorporated some ideas from these experiments into her diet plan and exercised routine to help the dieter achieve their target weight and stay healthy.

Jillian Michaels’s diet plan focusses on three factors:

1. Self

This includes all the psychological and sentimental matters related to destructive eating practices leading to obesity.

The Jillian Michaels’s diet plan encourages the dieter to identify and change the problems related to eating behaviors such as eating when a person feels tensed or upset instead of hungry as this might help in controlling the calorie intake.

Jillian Michaels provides alternatives to deal with problems such as stress and emotional detail of being overweight.

Also, she inspires the dieters to conquer all the obstacles and stay motivated to achieve their targets.

2. Science

It refers to the knowledge about basic nutrition and how the calories from various food items are used in the body.

Jillian Michaels’s diet plan focusses on satisfying the needs of an individual.

She assumes that ingested food can be metabolized by three different ways such as the fast oxidizers, slow oxidizers, and balanced oxidizers.

Dieter having different metabolic types needs to consume a different combination of fats, protein, and carbohydrate to get the best output from their meals.

Fast oxidizers have a metabolism that can quickly convert the carbohydrates from their meals into energy and this leads to elevated blood glucose levels right after the meal.

Therefore, it is recommended that people who can rapidly oxidize their food should consume less amount of carbohydrate and high quantity of proteins and fats because proteins and fats are converted to energy more slowly, and the energy levels remain stable even after the meal.

Slow oxidizers tend to transform carbohydrates into energy very slowly. Therefore, they are advised to consume meals with high carbohydrate and low fat and protein content.

Balanced oxidizers should consume fats, proteins, and carbohydrates in balanced amounts as their metabolism tends to convert food into energy at a moderate pace.

3. Sweat

Jillian Michaels believes that performing a60 minute workout on a regular basis will help the dieter to stay fit and active.

Out of these 60 minutes, the first and last 5 minutes must be used for stretching and warm up while the rest 50 minutes should be used for doing exercises and different workout regimen.
