The success or failure of your diet plan ultimately depends on your compliance with the program. This is why it is important that you check the different features and services offered by each company. Some companies offer personalized diet plans that are designed to answer each client’s nutritional and weight loss need. Clients can even have the option of mixing and matching from the different sets of menus available.
Call it what you will: An eating plan, a lifestyle, a diet, a philosophy, but few things garner such heated debate as how to lose weight. The truth is, whether you’re on a low-carb keto program, devoted to the Paleo lifestyle, all in to the Whole 30 or remain committed to low-fat eating, these plans have more in common than you think. What’s more, follow any one of them religiously, and you’ll likely notice results.
Think cooking healthy meals is difficult and time-consuming? Think again. Annie Allen, a postsurgical nurse in Tampa Bay, Florida, let her freezer do half the work for her—and now she's down 52 pounds and runs about 10 races a year. "Frozen vegetables are as nutritious as fresh ones, and in minutes you have half of your meal prepared," she says. These frozen meals are also surprisingly healthy if you don't have time to mix and match one of your own.
Research shows this intensity combo also makes you faster. In a 2013 study published in the Journal of Applied Physiology, researchers found that when cyclists performed six weeks of 80/20-style training, they more than doubled their power and performance gains, such as lactate threshold, compared to when they spent more time in moderate training zones.
When you want something sweet, all those fat-free, sugar-free options seem like a smart choice for weight loss. But researchers at Cornell University found that overweight people who choose low-fat versions of snack foods rather than the regular kinds consume, on average, twice as many calories. "The terms 'fat-free' or 'sugar-free' can create a green light effect, triggering people to eat more," says dietitian Cynthia Sass, RD. But many fat-free foods have about the same number of calories (or more) as their full-fat counterparts. 

HCG, or Human Chorionic Gonadotropin, is a hormone produced during pregnancy by the placenta after implantation, and doctors sometimes prescribe it for fertility issues. But this hormone has also gained popularity as a weight-loss supplement — and using it as such can be dangerous. In fact, the U.S. Food and Drug Administration (FDA) warns against purchasing over-the-counter hCG, as these supplement products are illegal. (34)
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key. 

There’s a reason why protein takes center stage in many popular diet plans: it helps you feel full and stokes your metabolism enough to help you avoid the typical one or two pounds most adults gain each year. Your body burns slightly more calories after eating protein compared with fats or carbs, and protein from food also helps keep your muscles from deteriorating as you age. (Strength-building exercise is another important part of this process.) In order to get these benefits, you need to include protein at each meal, and getting adequate amounts of protein at breakfast — about 20 grams — is especially important. Making a beeline for the bagels or cereal means your body misses a key opportunity to rebuild muscle tissue, which naturally breaks down as you sleep. If this is your morning routine, your muscle mass will start to decline, and that means your metabolism will slow down. So skip the AM pastries and other carb-rich fare, and opt for an omelet or smoothie made with Greek yogurt or protein powder, instead.

You don’t have to be the next Usain Bolt in the making to enjoy some serious belly-slimming results from hitting the track from time to time. Even a moderate-rate jog a few times a week can blast through that belly fat; in fact, a study conducted at Duke University Medical Center found that, over the course of an eight-month study, overweight adult study subjects who jogged 12 miles a week lost the most belly fat and burned 67 percent more calories than participants who did an equivalent amount of resistance exercise, or a combination of cardio and resistance work.
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
