Stop treating your kitchen like an all-night diner and you’ll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you’re finished with dinner at night, shut the fridge and don’t look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the 40 Things Healthy Cooks Always Have in Their Kitchen are there waiting for you.
Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
●Put tempting foods out of sight, out of mind. We naturally gravitate toward foods that are easiest to reach. So put candy on a high shelf or inside another bag behind something else so you’ll be less likely to go get it, says Cynthia Sass, co-author of “The Flat Belly Diet!” Put smarter choices, such as fresh fruit or popcorn, in bowls where they’re visible and within arm’s reach. Keep a water bottle with you so you won’t have to rummage through the fridge or walk to a vending area to get a drink.
Why does this popular plan work? For one thing, it pushes wildly healthy staples to the forefront (think: nuts, vegetables, fruit, olive oil). For another, it's simply delicious, thanks to it's focus on fresh, simply prepared dishes like grilled fish with lemon and whole wheat pita with hummus. Science agrees: One meta-review of 16 studies, found the eating M.O. helped those on it lose an average of 8.5 pounds.
Women usually need fewer calories than men, especially as they age. That's because women naturally have less muscle, more body fat, and are usually smaller than men. On average, adult women need between 1,600 and 2,400 calories a day. As you age, you need to take in fewer calories to maintain the same weight. You can also keep your weight healthy by increasing how much physical activity you get.
Get enough calcium. Adults typically need around 1,000 milligrams of calcium every day to help maintain muscle and nerve function, and it's necessary for healthy bones and teeth.[21] But calcium may also help prevent the body from storing visceral fat in the abdomen. Though studies have not shown a drastic change in weight due to increased calcium intake, researchers suggest that it may have a small effect in some people. Calcium requires vitamin D to be absorbed into the body; therefore, be sure to get enough vitamin D as well.[22] Sources of calcium include:[23]
WeightWatchers is one of the best known weight loss programs around. The reason it’s successful is that it’s often viewed as one of the easier programs to follow, helping you to change the way you think about and behave around food. Nothing is off limits, so you can still enjoy your favorite meals and snacks, even a drink of alcohol now and then, meaning...
The menstrual cycle itself doesn’t seem to affect weight gain or loss. But having a period may affect your weight in other ways. Many women get premenstrual syndrome (PMS). PMS can cause you to crave and eat more sweet or salty foods than normal.4 Those extra calories can lead to weight gain. And salt makes the body hold on to more water, which raises body weight (but not fat).

Nuts have a very high satiety power—meaning they make you feel fuller after eating than many other foods. And even though they’re high in calories, those calories appear to be processed differently in the body. University of Michigan researchers found that men who added 500 calories’ worth of peanuts a day to their diet gained no excess weight at all.


Almonds, peanuts, walnuts, pistachios — at GH, we're nuts about nuts! People who snack on nuts may have lower abdominal fat than those who munch on carb-based treats, according to a 2015 study in the Journal of the American Heart Association. Nuts are rich in monounsaturated fats, a heart-healthy (and more satisfying) pick than their grain-based counterparts.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.

Also, while your menstrual cycle may not affect weight gain or loss, losing or gaining weight can affect your menstrual cycle. Women who lose too much weight or lose weight too quickly may stop having a period, or have irregular periods. Women who have obesity may also have irregular periods. A regular period is a sign of good health. Reaching a healthy weight can help women who have irregular periods to have cycles that are more regular. Learn more in our Menstrual Cycle section.
“Most people who have been lean their whole lives have a much better understanding of proper portion size than people who are overweight,” says Deborah Riebe, Ph.D., a professor in the department of kinesiology at the University of Rhode Island. “If they go out to eat, they’re much more likely to ask for a doggie bag right away or to leave food on their plate rather than cleaning it up.”
Continuing weight loss may deteriorate into wasting, a vaguely defined condition called cachexia.[31] Cachexia differs from starvation in part because it involves a systemic inflammatory response.[31] It is associated with poorer outcomes.[26][31][32] In the advanced stages of progressive disease, metabolism can change so that they lose weight even when they are getting what is normally regarded as adequate nutrition and the body cannot compensate. This leads to a condition called anorexia cachexia syndrome (ACS) and additional nutrition or supplementation is unlikely to help.[28] Symptoms of weight loss from ACS include severe weight loss from muscle rather than body fat, loss of appetite and feeling full after eating small amounts, nausea, anemia, weakness and fatigue.[28]
You start to link up the cost of points with the cost of certain foods on your body, without any item every becoming taboo or strictly off-limits. Our tester found the point system both easy-to-use and eye-opening. “I can’t believe how many ‘healthy’ or at least innocuous foods are actually bad for you,” she remarked, noting how diet staples like granola bars took a big bite out of her daily allotment of points.

Eat Breakfast Every Day. One habit that's common to many people who have lost weight and kept it off is eating breakfast every day. "Many people think skipping breakfast is a great way to cut calories, but they usually end up eating more throughout the day, says Elizabeth Ward, MS, RD, author of The Pocket Idiot's Guide to the New Food Pyramids. "Studies show people who eat breakfast have lower BMIs than breakfast-skippers and perform better, whether at school or in the boardroom." Try a bowl of whole-grain cereal topped with fruit and low-fat dairy for a quick and nutritious start to your day.
