Obesity among children and adults dramatically increases the risk of chronic illnesses such as heart disease and type 2 diabetes. What are the contributing factors that lead to being overweight? In this seminar, Harvard Medical School doctors and researchers will address the stigma that surrounds obesity and discuss concrete methods, including changes to sleep and diet, that could help scale back this growing problem. Each spring, Harvard Medical School's Office of Communications and External Relations organizes a series of four free "mini-med school" classes for the general public in the heart of Boston's Longwood Medical Area. At the end of the seminar series, participants who attend three out of the four sessions receive a certificate of completion. Topics are selected for their appeal to a lay audience and have included the human genome, nutrition, sleep dynamics and health care access. Faculty from Harvard Medical School and its affiliate hospitals volunteer their time to present these lectures to the community. More »
Skimp on fluids, and your body will release an antidiuretic hormone that leads to water retention that could affect the scale, Dr. Setlzer says. While this sneaky effect is one reason why the scale is a poor measure of body mass loss, you can outsmart it by drinking more—particularly if you fill your glass with water or non-calorie alternatives like unsweetened coffee and tea.
Glassman suggests starting with a calorie baseline: If you're trying to lose weight, she recommends a meal plan that contains (roughly) 1,500 calories, with 40 percent coming from whole, fiber-rich carbs, 30 percent from protein, and 30 percent from healthy fats. That balance is ideal for keeping energy levels up and helping you build lean muscle while squashing hunger and the cravings that come with it, she says.
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.
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.
Ranging from just-juice to just-tea cleanses, these typically short-term plans can be dangerous. “Detoxes and cleanses are usually low in calories, protein, and fiber, all nutrients that our bodies need to function,” says Alissa Rumsey, RD, who is in private practice in New York City. “These plans leave you feeling hungry and cranky, causing a rebound food binge once you stop the detox.”
“Don't like eating meat?” asks Ginger Hultin, RDN, a dietitian in private practice in Seattle and a spokesperson for the Academy of Nutrition and Dietetics. “Then don't be paleo! Travel a lot and rely on eating out? The DASH diet may end in frustration for you.” The bottom line: The diet you choose needs to be safe and effective, while taking into account your lifestyle.
Most low-carb diets advocate replacing carbs with protein and fat, which could have some negative long-term effects on your health. If you do try a low-carb diet, you can reduce your risks and limit your intake of saturated and trans fats by choosing lean meats, fish and vegetarian sources of protein, low-fat dairy products, and eating plenty of leafy green and non-starchy vegetables.
Make your own. It’s easy! From one 14-ounce can of no-salt-added cannelini beans, spoon out 2 tablespoons of beans. Puree the rest. In a medium nonstick pot, sauté 5 cloves of chopped garlic until translucent. Add 2 cups low-sodium chicken broth and 1 head of escarole, chopped, or a package of frozen chopped spinach. Simmer for about 15 minutes. Add pureed beans, red pepper flakes and black pepper, to taste, and cook 1 minute longer. Garnish with the beans you spooned out plus, if you desire, a little chopped red bell pepper. Refrigerate or freeze what you don’t eat for easy soup prep for a future lunch or dinner.
Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
Grilling coaxes sweet-savory depth from endive and red onion in this delicious vegetarian side dish. Fresh figs lend a bright, jammy acidity in the summer, but don't hesitate to use dried come winter. Leave the root ends attached when trimming your onions and endive, so they hold together and don't slip through the grill grates. Serve as a salad, or eat alongside grilled chicken, steak, salmon, seared scallops or whole roasted fish.
"Researchers around the world say what really works is not just cutting calories but satisfying your hunger with the right kinds of foods," says Health’s Frances Largeman-Roth, RD. In fact, women following a low-fat diet who were allowed to fill up on all the fruit and vegetables they wanted lost 23% more weight than women on a low-fat diet alone, a new study from the United Kingdom reports.
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
Eating at home puts you more in control of what you eat and how much you eat. One study published in the International Journal of Behavioral Nutrition and Physical Activity found that people who ate at least five home-cooked meals per day were 28 percent less likely categorized as overweight. And they were 24 percent less likely to have excess body fat than participants who ate less than three home-cooked meals per week. Here are the weight loss rules pros cheat on.
First things first – planning. Before you start to prep your meals, you need a nice, solid plan. Coming up with a meal plan may sound overwhelming at first, but it’s not as bad as it may seem. Just take it one step at a time and start with one, simple meal you love and that you know is healthy, and then work your way up. Soon, you’ll be prepping all your meals! Watch out – it gets addicting!
Coffee add-ins could be adding in unnecessary extra calories to your diet. According to the Mayo Clinic, common calorie culprits include sugar, half-and-half, whipping cream, and even fat-free milk. Meanwhile, black coffee has only five calories. Registered dietitian Andy Bellatti adds that another good swap is unsweetened plant milk instead of the sweetened ones for your beverages.
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)
