Variety: Nobody wants to eat the same thing day in and day out. That's why a variety of food items is essential for a diet plan to be sustainable. Also, variety as a criterion for determining the best diet plans refers not only to food items but also to groups of people. For example: Is the diet plan available to diabetics? Men? Women?

Ansari says alcohol can prevent weight-loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly."

Getting enough protein every day, whether you’re in a quick-fix or long-term mindset is important for keeping your muscles and metabolism healthy throughout weight loss. Make sure you’re having some chicken breast, lean ground turkey, fish, seafood or tempeh that’s the size of a deck of cards at every meal. When snacking, have 2 eggs, 1/4 cup of nuts, or 3/4 cup of Greek yogurt or cottage cheese to meet your protein needs and stay full and feel slim.

Women should aim for at least 25 grams of fiber per day (based on a 2,000-calorie) diet, according to the most recent U.S. Dietary Guidelines. Start with our high-fiber diet plan.
