So it’s no wonder that losing weight and getting in shape are among the most popular resolutions year over year, because so many people can’t keep them; 80% of New Year’s resolutions fail by February. So Moneyish spoke with several leaders in the field of obesity research and prevention who have reviewed the science surrounding weight gain and loss to explain what to eat and avoid; how much exercise you need and which workouts work best; as well as their tips for making these moves a part of your new, well-balanced life in the New Year.
When it comes to the "best" diet for most people, this one consistently ranks at the top of every list. If you can't afford a cruise to the Mediterranean (yet!), at least you can eat like the beautiful, long-living, and famously healthy people from the region. The Mediterranean diet teaches you to eat like a Sardinian, one of the "blue zones" identified by researchers as having a high number of people living past 100—by eating more fish, olive oil, healthy fats, and fresh vegetables. The point is to have not just a longer life but also a healthier and happier one, whether you're trying to lose weight or not. (Really—research shows that you can reap the benefits of the Mediterranean diet without cutting calories.)
What's more trustworthy than a diet built by experts from the Mayo Clinic? Created by doctors, nutritionists, and all-star chefs, the plan has a few phases: In the first, you should lose 6 to 10 pounds in two weeks. After that, you can expect to lose 1 to 2 pounds a week until you reach your goal weight. You're also given plenty of resources and advice to help you keep the weight off.
Yes whey: the American Journal of Clinical Nutrition found that high-protein shakes are a vital part of a weight loss plan, so don’t hold back – especially at breakfast. According to research from the University of Bath, eat 700 calories before 11am and you’ll have better blood sugar levels than those who skipped the most important meal of the day. It’s the best excuse you’ll have of sticking with a morning fry-up and avoiding a costly Starbucks lunch.

Plain and simple: We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink, for instance, won't make you feel full the way eating a bowl of veggie- and protein-packed stir-fry will. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.) Some other ways to skip sugar? Check 'em out here.
Women’s challenge with weight loss also comes down to nature. Nature wants to preserve a woman’s ability to bear children. When you’re in a calorie deficit, it can interfere with your fertility, so your body fights weight loss to prevent jeopardizing your reproductive capacity. So don’t cut more than 1,000 calories a day or eat fewer than 1,200 calories daily.
The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.
If muscling up is key to shedding timber, you might as well do so efficiently. Rehash your recovery period by introducing short rest intervals within your sets. Switching your 120-second rest between sets to a 60-second intra-set break brings greater strength gains and increased power output, according to a study published in the Journal of Strength and Conditioning Research.
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.)

There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

"Sleep is a cornerstone of weight management because of the impact it has on your hormones that control how you burn fat, how you store fat, and how you're maintaining muscle. The better your hormone balance, the better your weight management. I work my butt off to get eight hours a night, but right now I'm at six—the show is murdering me! Even if I go to bed early my son wakes up."
A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.

If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
Consider them “good carbs”. Their bulk takes up space in your stomach, helping you feel full and eat less. The top fiber food: beans, which contain 8g per 1/2 cup. Research shows that guys who added 12g of fiber a day to their diet lost a quarter of an inch from their love handles, without otherwise modifying their diet. Here are some of the best sources.
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.
As chronic obstructive pulmonary disease (COPD) advances, about 35% of patients experience severe weight loss called pulmonary cachexia, including diminished muscle mass.[32] Around 25% experience moderate to severe weight loss, and most others have some weight loss.[32] Greater weight loss is associated with poorer prognosis.[32] Theories about contributing factors include appetite loss related to reduced activity, additional energy required for breathing, and the difficulty of eating with dyspnea (labored breathing).[32]

While any diet that reduces your intake of fat, sugar, and carbohydrates will help you lose weight, a weight-loss plan can offer you much more and give you a much better chance of long-term success. As weight-loss plans have been developed by dietitians, fitness coaches and nutritionists, they are designed to help you lose weight safely and progressively, while altering your attitude to food and encouraging you to adopt healthier habits.
The upgrade is a touch steeper than it is for other tracking app upgrades — most run $4–5 per month. But we found that those inexpensive alternatives were chaotically organized and slow to respond, elements that had us avoiding opening them at all. SparkPeople and Lose It! both came with lots of lag time and finicky search bars that made us hesitant to launch the apps, let alone log in three or more times a day.
If you're not a fan of meat, you may do better on a weight-loss program that emphasizes fruits and vegetables. A 2012 study published in The Journal of the Academy of Nutrition and Dietetics found women over 50 were more successful at keeping the weight off when they followed diets that increased their intake of fruits and vegetables and ate less meat and cheese. Good weight-loss programs with an emphasis on fruits and vegetables that might help women over 50 lose weight include the DASH diet, the Mediterranean diet and the Mayo Clinic diet.
But the whole idea of fast weight loss may be the root of the problem. According to a Time expose on the subject: “When people are asked to envision their perfect size, many cite a dream weight loss up to three times as great as what a doctor might recommend.” An improbable and disheartening goal, and one that obscures the truth that losing small amounts of weight — even ten pounds — still has great health benefits.

Eating patterns that restrict certain food groups can certainly help you lose weight, but many people find it hard to continue to eat that way forever. If you want to think of your diet like a relationship, you don’t want to be in an “it’s complicated” or “on-again, off-again” situation. You want to find your match — a meal plan you can feel content with for the long haul. That doesn’t mean you have to ditch all of your favorite foods for eternity. It’s okay to flirt with the foods that make you swoon, but you don’t want to settle down with them. When your healthy habits are solid, enjoying your favorite foods sometimes is no big deal.
“My dad is like a food-pushing wizard, he’s always pulling stuff out of his pockets or showing up with delicious food,” says Mary Mock. While the family tradition of surprise sweets was fun, when it came time to lose weight, she knew she had to put a stop to all that temptation. “At first, he seemed hurt when I kept saying no but when I explained it was for my health, he got on board. Sometimes I still have to remind him though!” she says.
As women age, weight creeps up too, with the average women gaining about one pound per year in their 40s and 50s, resulting in an added 10 to 15 pounds. The drop in estrogen levels during this time of perimenopause (the years leading up to menopause) contributes to weight gain and can change the way you distribute fat. You may gain weight in your belly more readily than you did in younger years.
Your parents weren’t kidding about how important veggies are for a healthy body. What they probably didn’t tell you, however, was that snacking on veggies is also one of the easiest ways to shed unwanted belly fat, too. According to a study published in the Journal of the Academy of Nutrition and Dietetics, opting for non-starchy veggies, like cauliflower, broccoli, and cucumber, as snacks helped overweight kids shed 17 percent of their visceral fat while improving their insulin sensitivity over a five-year period. Think snacking on veggies will leave you hungry? The 20 Most Filling Fruits and Veggies will have your belly satisfied in no time.
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.
“I started my 78-pound weight-loss journey by tracking everything I ate with the Lose It! app. I track right after I finish because if I wait until later, I don’t always remember. Sometimes I’ll even record before I eat, so I know if I have enough calories for the day. That, paired with daily weigh-ins helps to keep me accountable.” —Kari Hammond, 42

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.
Whole foods include fruits, vegetables, beans, nuts, seeds, whole grains, eggs, seafood, chicken and so on. Food philosophies may differ around which of these foods to emphasize, but that’s okay, since the evidence shows that there isn’t a single best way to lose weight. The goal is to select an approach that feels sustainable to you. If you can easily live without pasta, perhaps a low-carb method centered around veggies and quality proteins, like seafood, chicken, and lean beef would be a good fit. Vegans and vegetarians can lose weight by choosing fruits, vegetables, whole grains and plant proteins. Nut lovers may do well shedding pounds with a Mediterranean-style menu. Whatever diet appeals to your appetite and way of life, focusing on whole foods is something that all plans promote.

Jen Tallman never thought she would have the courage to pursue a career in fashion due to her size...until she dropped 110 pounds by reducing her caloric intake and picking up running. Now she works at Chanel. How does she resist the temptation to deviate from her newfound healthy habits when eating out with friends? She checks out the menu beforehand so she always knows her healthy options. Just make sure you know how to spot what's actually healthy—restaurants can have a knack for trying to make you think things are healthier than they are.


First, as women near midlife, their ratio of fat to body weight increases rapidly. Second, many women see that new fat mostly around their bellies. This is “visceral fat” and it can change the entire shape of your midsection. Visceral fat cells are like miniature endocrine organs that are especially active, setting off inflammation and increasing insulin resistance. Third, visceral fat gets a huge boost from lifestyle issues like depression and stress, poor sleep, smoking (proven to increase belly fat ), irritability, and drinking fructose-sweetened beverages (leads to more visceral fat and decreases insulin sensitivity).
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
As the weight-loss process varies from person to person, there is no one-size-fits-all when it comes to dieting. The efficacy of any weight-loss program is dependent upon your commitment to the plan and how well it fits into your lifestyle. This is why it’s important to consider your weight-loss goals and lifestyle parameters before launching into a weight-loss program.
Including your significant other in your workouts can help to keep you on track, even if your goals aren't necessarily the same. "My hubby and I make exercise outings 'our' time," says Twyla Grimes, who knocked off 26 pounds by combining an hour on the stairmill or treadmill with strength training. "We'll go to the gym for an hour and lift weights together. Having him there keeps me accountable."
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
