Without those behaviors nailed down, if you're hungry all the time, are ruled by cravings, and have no energy, the chances of you maintaining your diet are minuscule. You may lose what you want, but as soon as you go back to eating your normal foods in the normal amounts, you'll likely regain all you've lost, and in some cases add on an extra few pounds. Ultimately, long-term weight loss requires some short-term behavior change and healthier habit formation. That's why we created our Good Housekeeping Nutritionist Approved Emblem, which exists to help turn smart food choices into healthier eating habits.
