While Whole30 calls itself a "reset," registered dietitian and NASM-certified personal trainer Whitney English Tabaie, MS, RDN, CPT, said that since it's an elimination diet, if "someone has a food sensitivity, Whole30 may help to identify what it is."
But registered dietitian Jackie Ballou Erdos, MS, RD, CDN, owner of Balancing Act Nutrition said that Whole30 also makes a lot of other claims on its website, such as "millions of people have changed their lives . . . eliminating cravings, improving energy and sleep, reporting an improvement in allergies, anxiety, chronic pain, digestive issues, skin conditions; and losing weight healthfully and sustainably."
It also claims that it can "change your life in 30 days" and "reset your health, habits, and relationship with food, and discover lasting food freedom." Jackie warns that although you may feel desperate to make a change, not everyone will experience what Whole30 promises.
