Enjoy the rich flavor of sweet potatoes? While home on Sundays, cook up a batch. Wrap each one in foil and bake for about an hour at 425 degrees F, or until their luscious, sweet juices start to ooze out into the foil. At work the following week, just pop one in the microwave for a quick warm-up. They’re loaded with taste, so they don’t need any extra toppings. If you want a little zest, swirl in a teaspoon or two of no-salt-added Dijon mustard or a quarter cup of plain nonfat Greek yogurt.
Fiola Sowemimo, MD, board-certified in internal and bariatric medicine, says that the quality and quantity of food you eat is only half of the weight loss equation. “Regardless of which diet you choose, when you eat is important too,” Dr. Sowemimo says. Starving during the day and ignoring hunger could lead to bingeing later, she says.

Eating regular meals at regular times could actually help normalize your metabolism, according to Dr. Bazilian.

Others are created with weight loss as a primary goal. “It is important to remember that we are all very unique individuals,” says Kyle. “We all have different states of health and different lifestyles, which could affect what diet plan is best for us. That means that you should not be considering what is working for your friends or family members — and instead should pay attention to what works for you individually.”

A quinoa salad made with 1 cup of cooked quinoa tossed with 1 cup of mixed diced raw veggies such as grape tomatoes, red onions and peppers, 1/2 cup of firm pressed tofu, 1 teaspoon of sesame oil and grated ginger for 390 calories also makes a good lunch option on your weight-loss diet. Or try a simple turkey sandwich made with two slices of whole-wheat bread, 3 ounces of turkey breast with lettuce, tomato and mustard and served with 6 ounces of nonfat yogurt, a small apple and 1 cup of sliced cucumbers for 440 calories.
