The Whole30® was created in 2009 and is focused on eating whole, natural, unprocessed foods including meat, seafood, eggs, vegetables, fruits, nuts, and seeds.The diet focuses on eliminating all dairy, grains, sugar, legumes, alcohol, and processed foods from your diet for thirty days to help reset your body, increase energy, decrease inflammation, and improve overall health. 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.
