Dr. Smith says the regimented plan involves scheduling meals, mainly of plant-based foods in controlled portions, to create a negative energy balance... where your body extracts energy from stored fat, thereby boosting calorie burn and reducing fat. Most dieters don't realize that simply by cutting back as little as 20 percent at each meal, they can lose a significant amount of weight.
During the first week of a reduced calorie and carbohydrate diet, you will flush a lot of excess water and lose weight rapidly. This is neither unhealthy, nor an indication of what your rate of weight loss will be like during weeks 2 and 3. With that said, men should expect to see an 8 to 12 pound loss during these 3 weeks, and women will likely lose 5 to 10 pounds.
For example, when it comes to hormones, ghrelin makes you hungry, leptin and other hormones keep you feeling full, Nadolsky says. Thyroid, cortisol, insulin, testosterone, and estrogen all influence how you metabolize and store energy. Meanwhile, genetics have a large influence on both basal metabolic rate (how many calories you burn just to live) and hormone health. While all of these things are impacted by our diet, they’re not only controlled by the way we eat. And, in fact, while sleep, stress management, and, when needed, medication can help regulate other hormone levels such as estrogen and thyroid, our hormones and other physiological processes are often out of our control. And by the way, being able to impact our hormone levels and metabolism with our diet doesn’t always work out in favor of weight loss. As a 2016 review notes, one of the reasons weight loss by way of caloric restriction isn’t efficacious is because “this strategy is countered by the body’s natural physiological response to negative energy balance.” In other words: The body fights back against caloric restriction.
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.
Eating sugar, especially refined sugars added to sweeten food and beverages, is a leading contributing factor to visceral fat. The glucose and fructose that come from sugar are simple carbohydrates that get quickly absorbed into the bloodstream and metabolized to release energy. When there’s excess intake, they get converted to glycogen to be stored in fat tissue. Eating a lot of sugar also spikes your blood sugar, which triggers insulin to be released in large amounts, potentially leading to a condition called insulin resistance that’s associated with metabolic syndrome. Cutting out all sweetened foods and drinks, including fruit juices, is one of the best things you can do today to lose belly fat fast. Learn to enjoy small amounts of natural sweeteners such as fresh fruit, raw honey, dates, and coconut crystals. Don’t be tempted by these other 15 of the worst foods for your belly.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
