Whole30 can help with weight loss as it restricts many foods that most of us tend to overeat. It also focuses more protein and vegetables, which can help us feel full on less overall calories. "However, it all comes down to how many calories you're consuming. If you end up eating just as many calories as you currently do, then you may not notice a significant change in weight," said Kelli. You may also eat more fat like avocados and nuts, and complex carbs like sweet potatoes and bananas.
If a person does end up losing a few pounds, Jessica said, "the weight loss is unlikely to be sustained when they go back to their normal eating patterns at the end of the 30 days."
