You don’t need to bust out the measuring cups to properly portion out your food: A serving size of meat is roughly the size of a deck of cards or the size of the palm of your hand. Your entire fist should be the size of a serving of veggies (although the more, the better!). A serving of fat, such as butter or coconut oil, should be the size of your thumb. Your carb serving should be no bigger than what can fit in your cupped hand. For other ways to eyeball your proper serving sizes, check out What the Perfect Food Portion Sizes Actually Look Like.
This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason. (1) (A pro tip? If you're planning on doing the diet, consider perusing this complete keto food list and reading up on the healthiest fats for keto diet followers.)
Of carbs and protein, that is. Carbs certainly aren’t the enemy; you can totally enjoy carbs and still lose weight. The trick is to choose something complex (like brown rice, quinoa, or whole grain bread) or something refined (like white rice, white pasta, and white bread), and pair it with a protein. So if you’re having crackers for a snack, make sure you also eat some almonds or a stick of string cheese. “I always incorporate a protein and carbohydrate at every meal,” Jim White, RD, ACSM Health, and owner of Jim White Fitness & Nutrition Studios told us in our 30 No-Diet Diet Tricks article. “It can curb your appetite and it slows down the glycemic index of some of your higher sugar foods.”
Sugar contains calories but nothing else, and "empty calories" are the last thing you want on a diet, says Stephanie Karpinske, MBA, M.S., R.D. Sugar is also digested quickly so you're hungry soon after you eat it. It raises insulin levels, which promotes fat storage. Plus, it can be addictive because it raises levels of serotonin -- the feel-good chemical in the brain that helps us relax during times of stress. That's one reason why weaning yourself off sugar is so difficult.

Where commercial weight loss programs go hands-on, the Mayo Clinic Diet goes streamlined. The vibrant, best-selling hardback (that looks a lot like a fun middle school health textbook) is the first resource for diet information, you can also employ the sleekly designed but minimalist app, plus a full website of tips, recipes, and workouts. Those patient enough to cycle through all of Mayo’s resources will find lots of solid health information.
Athletes at their prime must consume many more calories than the average person to be at peak performance, but as they age and become less active may find that their old eating habits are hard to break. Former athletes who have gained weight and want to become lean and muscular as they age may turn to weight loss programs for help getting on track.
The sad truth is that conventional ideas – eat less, run more – do not work long term. Counting calories, exercising for hours every day and trying to ignore your hunger? That’s needless suffering and it wastes your time and precious willpower. It’s weight loss for masochists. Eventually almost everyone gives up. That’s why we have an obesity epidemic. Fortunately there’s a better way.
Protein is naturally filling and takes longer to digest than simple carbohydrates. When people drank a whey protein drink, they lost about 4 pounds more and about an inch more from their waists over 6 months and felt less hungry than people given a carbohydrate shake instead. Other research in mice, found that when mice were given extra whey protein they gained less weight and body fat and more lean muscle, even when calories were the same. Whey protein is found naturally in yogurt and other dairy.
If you eat your dinner restaurant style on your plate rather than family style, helping yourself from bowls and platters on the table, you’ll lose weight. Most of us tend to eat an average of 150 percent more calories in the evening than in the morning. You’ll avoid that now because when your plate is empty, you’re finished; there’s no reaching for seconds.
Just because Fluffy is on a diet doesn’t mean you can’t reward her with a few treats now and then. We love Twin Critters’ low-calorie cat treats because they’re made only with 100% pure whitefish, nothing else. They’re incredibly low in fat and calories, which is great when you want to treat a cat with weight issues. They’re also high in Omega-3 fatty acids, which promotes a healthy skin coat.
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
Skimping on sleep sets you up for a host of health problems, such as increased risk for depression, type 2 diabetes, and stress. Here's one other benefit to spending enough time in bed: You're more likely to be a healthy weight. University of Chicago research revealed that dieters who were well-rested lost more fat than those who were sleep deprived.

Studies found that people who keep food diaries wind up eating about 15 percent less food than those who don’t. Watch out for weekends: A University of North Carolina study found people tend to consume an extra 115 calories per weekend day, primarily from alcohol and fat.  Then cut out or down calories from spreads, dressings, sauces, condiments, drinks, and snacks; they could make the difference between weight gain and loss. Here are 50 easy ways to lose weight naturally.


Accessibility to foods: Some diet plans ship foods straight to your door, while others require you to shop for very particular ingredients. There are also a range of price points, with some diets costing substantially more than others. Consider whether the food allowed on a particular diet will fit into your budget and be relatively easy to find at grocery stores.

"You also can gain up to several pounds, depending on where you are in your menstrual cycle," Zied says. Estrogen encourages bloating by stimulating the kidneys to retain sodium. If you're taking oral contraceptives, note that older prescriptions containing higher doses of estrogen can cause more bloating than the new, lower-dose pills. (Some studies show no difference in water-weight gain between a low-dose oral contraceptive and a placebo.)

Weight loss and weight maintenance are top concerns for most of us, but there are so many rumors and fads out there that it's hard to keep track of what really works. We've sorted through the claims by talking to registered dietitians and doctors and reading the most recent studies to give you trustworthy answers to 15 top weight loss questions, including:

Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people feel best when keeping TSH slightly below normal.
Preferred tastes: Think about whether the foods on a given diet are things that you generally enjoy. If you hate eating your greens, you might not like a diet filled with salads; but if you have a sweet tooth, a diet that substitutes milkshakes for meals might be more up your alley. Ask yourself whether you will enjoy the foods on a given diet, or if it will feel like a “diet” food that you won’t be able to stick with long-term.

eDiets doesn’t believe in reinventing the wheel. Instead, this diet marketplace gives members access to some of the most effective diet plans to date. While eDiets does offer fitness tools and online tracking capabilities, what most members really enjoy about eDiets is their weight loss food plan selection. Particularly suited for people with specific dietary or health restrictions, eDiets helps you find a menu that both suits your lifestyle and caters to your particular needs. For example, if you are a diabetic, their Glycemic Diet will deliver you nutritious and tasty meal plans that will help you maintain health and lose weight at the same time. Other weight loss meal plans include a Mediterranean Diet, Heart Smart Diet, and Gluten-Free option.
A cup of raspberries delivers a whopping 8 grams of fiber (that's more than double what's in a cup of strawberries and about the same amount in a cup of some types of beans). What's so great about all that fiber? Recent research in the Journal of Nutrition suggests eating more fiber as a way to prevent weight gain or even encourage weight loss. Over the course of the two-year study, the researchers found that boosting fiber by 8 grams for every 1,000 calories resulted in about 4 ½ pounds of weight lost.
Yes, you can pump iron without bulking up, and no, you will not look awkward. Lifting weights stokes your metabolism for a few days after your workout—meaning you continue burning calories long after you leave the weight room. One study found that strength training 30 to 40 minutes twice a week for 4 months, could increase an average woman's resting metabolism by 100 calories a day.
You're probably eating more sugar than you realize. The average person takes in 22 teaspoons of sugar a day—more than three times the amount suggested by the American Heart Association. The white stuff is added to foods that don't even taste sweet, such as breads, condiments, and sauces. Read food labels carefully: ingredients are listed in the order of how much is in the food, so if sugar is near the top, put it back on the shelf.
Conversely, the more food in front of you, the more you’ll eat—regardless of how hungry you are. So instead of using regular dinner plates that range these days from 10 to 14 inches (making them look empty if they’re not heaped with food), serve your main course on salad plates (about 7 to 9 inches wide). Instead of 16-ounce glasses and oversized coffee mugs, return to the old days of 8-ounce glasses and 6-ounce coffee cups.
A. Compile a detailed food diary for at least a week. "Most of us underestimate how many calories we consume, so it's possible you're eating more than you think," says Cynthia Sass, R.D., coauthor of Your Diet Is Driving Me Crazy (Marlowe & Company, 2004). If the calorie count is correct, then the wrong exercise program could be to blame. "If you're not strength training while you're dieting, you may be losing lean tissue, and that cuts your metabolic rate," explains Sass.

You might feel silly, but it works. When Alan R. Hirsch, MD, neurological director of the Smell & Taste Treatment and Research Foundation in Chicago, tried this with 3,000 volunteers, he found that the more frequently people sniffed, the less hungry they were and the more weight they lost—an average of 30 pounds each. One theory is that sniffing the food tricks the brain into thinking you’re actually eating it.

Another way to trim carbs and calories and lose weight fast is by making your sandwich open-faced. Opting for one slice of bread instead of two will save you 70-90 calories, and leaves you more room to pile it high with healthy toppings like lettuce, tomato, sprouts, and avocado. Still hungry? Pair your sandwich with a side of baby carrots or bell pepper strips. The water and fiber in the veggies will fill you up and help with your weight-loss efforts.


Weight loss once again came in first place for New Year’s Resolutions, sharing its spot with “becoming a better person.” For a lot of us, becoming a better person starts with feeling better about ourselves. The start of a new year may be primetime to renew dedication to health and happiness, but periodic sprints of weight loss do not equate to wellness. That’s why the best diet is the one you can sustain for the rest of your life.
