Diet plans can be a great resource for people looking to lose weight or streamline their nutrition. When choosing one program over the other, think about the individual foods allowed on the diet—if you must source some ingredients yourself, does this fit into your budget? Do the meals satisfy your preferred tastes, and do they incorporate alternatives for food allergies or sensitivities?
The plan laid out in the book Flat Belly Diet! says you will lose up to 15 pounds in 32 days. The first phase offers an initial anti-bloat plan, followed by four weeks of strict eating that incorporates healthy monounsaturated fats at every meal. While the diet has no research to support it, the plan is loosely based loosely on the Mediterranean diet, which is highly backed by research.
The degree to which exercise aids weight loss is open to debate, but the benefits go way beyond burning calories. Exercise can increase your metabolism and improve your outlook—and it’s something you can benefit from right now. Go for a walk, stretch, move around and you’ll have more energy and motivation to tackle the other steps in your weight-loss program.

To prep the kale for the salad, we’re going to add it to a large bowl with a little olive oil and rub all over the kale, massaging it until the kale reduces in volume and becomes less stiff. (This makes a huge difference in the texture of the kale and makes it much easier to eat. I like to buy pre-cut kale when I meal prep because it’s just easier and takes one less step out of the process.)


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.
Fresh salads with fruits and vegetables are a great way to pack a nutritious punch. But using a high-calorie dressing with lots of fat, salt, and sugar could be adding unnecessary calories. Libby Mills, MS, RDN, LDN, spokesperson for the Academy of Nutrition and Dietetics, says pre-made dressings are one of the worst offenders. Instead, ask for salad on the side when eating out or use fresh lemon juice, vinegar, and olive oil for a lighter option. Here are other salad mistakes that could cause weight gain. 
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 »
Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.

Some diet plans, such as the MIND diet and the DASH diet, are meant to focus on certain areas of health — and weight loss may be a bonus. 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.”
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
And there's another benefit to using exercise as a weight-loss tool. If you lose weight by only reducing calories from your diet, you also run the risk of losing muscle and water in addition to fat. But exercise not only burns calories - it can also help you to increase your lean muscle mass. Since muscle burns more calories than fat, even when you are at rest, adding exercise to the mix can help make you a lean, mean, calorie-burning machine!
