Nutritionists Reveal the Biggest Weight-Loss Mistakes

When hunger strikes and you're not prepared, that's when unhealthy decisions are made. Stephanie Clarke, RD, recommends planning ahead as much as possible. If you can, sit down and plan your meals and snacks out for the next week or two in advance, and then hit the grocery store with a list to stock up on everything you need from fruit to veggies to the containers you need to make a week of salads. It means that you'll have the food you want to eat on hand when you want to eat it, "which is the key for sticking to healthy eating for the long term."
