Most people also lose weight on the Whole30® diet due to the drastic change in their diet. There is no calorie counting or portion control on the Whole30® but instead the focus is on what you eat and how it affects your body.

What is the Whole30® Diet?

Following the Whole30®, you cut out all of these foods for 30 days and then slowly reintroduce them to your diet one at a time so you can better understand how they affect your specific body and then make informed decisions about what to include in your diet to feel your best and be your healthiest.

The main foods that are avoided during the Whole30® are grains, dairy, legumes, sugar, alcohol, and all processed or fake foods. The diet focuses on real food that is natural and unprocessed including meats, seafood, eggs, vegetables, fruits, nuts, and seeds, and some oils.

The basic rules of the Whole30® diet are simple.

  • Eat whole, unprocessed foods that are full of nutrients and nourish the body. This can include vegetables, some fruits, meat, eggs, seafood, nuts, and natural oils.
  • Avoid eating any types of processed foods or grains including dairy, wheat, legumes (including peanuts), sugar, beans, corn, pasta, bread, rice, and other processed foods that normally come in a box or bag and are created in a factory.
  • Do not consume alcohol in any form.
  • Do not try to recreate your favorite processed foods or junk foods with Whole30® approved ingredients. No pancakes, muffins, breads, candy, etc.

Then as they reintroduce different foods to their body, they understand exactly how their body reacts to the food and can make an informed decision about whether or not to include that food in the future.
