The less you eat, the more your body thinks it's starving, so like a small child refusing to give up his favorite toy, your body isn't going to give up any fat stores until it absolutely has to. That means under-eating isn't going to eliminate stomach fat until there isn't enough muscle to consume.
Therefore, even if don't feed your tummy it won't just shrink down. In fact, the repercussions of hunger might result in drastic weight gain. Your metabolism will eventually become slower which in turn will make future weight loss difficult.
Some people who try the fasting diet for 3 days do it as a way to lose weight. While people do lose weight, it is important to note that the weight loss is water weight and not fat loss. Research has shown a positive correlation between increased water consumption and weight loss.
The amount of time it takes to lose belly fat varies from person to person. However, training harder and reducing your calorie intake to achieve a daily calorie deficit of 500 calories will lead to a weight loss of around 12 pounds within 12 weeks. This will likely also result in belly fat loss.
It's important to focus on reducing overall body fat, avoiding sugary and processed foods, limiting refined carbs, and incorporating resistance training and aerobic exercise. Additionally, drinking plenty of water, getting enough sleep, and reducing stress can help support a healthy and flatter stomach.
One reason belly fat is so hard to lose is that it's considered an “active fat.” Unlike some fatty tissue that simply sits “dormant,” belly fat releases hormones that can have an impact on your health — and your ability to lose weight, especially in the waist and abdomen areas.
Myth: You Shouldn't Eat After 7 P.M.
“However, there's no magic to the 7 p.m. time,” Dobbins says. “Losing weight is a matter of limiting our calorie intake, and most people tend to eat most of their calories in the evening, at dinner and snacking afterward.
When you have a slow metabolism, your body doesn't convert food into energy in sufficient quantities. So most of the food you eat is stored in the form of fats. This is the main reason why some people get fat even though they don't eat much.
If reducing overall body fat, including belly fat, is your ultimate goal, aerobic exercises that increase your heart rate, such as walking, running or swimming, and aerobic exercise combined with strength training are the gold standards when it comes to exercise that supports weight loss.
You Might Be Eating Too Little
This phenomenon is called “starvation mode,” and while your body isn't actually starving, it will naturally hold onto whatever calories it receives in an effort to help you maintain your energy balance.
While there isn't one magic food that will melt away belly fat, studies have reported certain foods have special belly-fat-burning benefits, such as avocado, artichokes, whole grains, kefir, green tea, eggs, peanuts and chickpeas.
Both 12-hour fasting and 16-hour fasting can be effective for weight loss, but 16-hour fasting may be more effective because it may lead to a greater reduction in overall caloric intake (through a more condensed eating window) and promote more significant reliance on fat burning.
And yes, sleeping counts as fasting! If you are looking for significant weight loss, you might consider working up to 18-20 hours of daily fasting (OMAD or one-meal-a-day), alternate day fasting (fasting every other day, with up to 500 calories on fasting days) or a 5:2 schedule (fasting for two days per week).
Getting a flat stomach really depends on two main factors. It is realistic to say that you can achieve a flatter stomach in as little as 6-12 weeks with a sound diet and exercise approach that places you in a slight and progressive caloric deficit for that time period.
"The stomach vacuum exercise involves contracting and holding in your stomach muscles while breathing deeply. The goal is to strengthen the transverse abdominis muscle, the deepest layer of the abdominal muscles, creating a slimming effect on the waistline."
