Keto, Whole30, intermittent fasting and other trend diets can spark quick weight loss but aren’t final weight loss solutions. According to Russell Medical nurse practitioner Leigh Goodman, lifestyle changes are what keep off weight.

“You have to be really, really careful because once you go off the diet, it’s not a lifestyle change,” Goodman said. “It’s just a change to lose weight. The lifestyle change you need to do in order to really improve your overall health.”
