Paleo
Eating like a caveman is so B.C.—or at least it should be, according to Heather Campbell, MS, RDN, LD, consultant dietitian. “Any diet that requires complete omission or serious restriction of entire food groups like carbohydrates or dairy can be problematic and create opportunities for nutrition deficiencies,” she explains.
“When your body isn’t properly fueled with a balance of all of the needed nutrients, then it will be impossible to create sustainable changes you’re looking for.” While Keto may lead to initial results, she points out that it’s not creating a lifestyle you can continue into the future, “then you’re less likely to see permanent positive change in your health.”
