OVERWEIGHT does not necessarily equal unhealthy. There are actually plenty of overweight people who are in excellent health. Conversely, many normal-weight people have the metabolic problems associated with obesity.That’s because the fat under the skin is actually not that big of a problem (at least not from a health standpoint; it’s more of a cosmetic problem). It’s the fat in the abdominal cavity, the belly fat, that causes the biggest issues.
If you have a lot of excess fat around your waistline, even if you’re not very heavy, then you should take some steps to get rid of it. Belly fat is usually estimated by measuring the circumference around your waist. This can easily be done at home with a simple tape measure.
Anything above 40 inches (102 cm) in men, and 35 inches (88 cm) in women is known as abdominal obesity. There are actually a few proven strategies that have been shown to target the fat in the belly area more than other areas of the body.
Here are six evidence-based ways to lose belly fat:

1: AVOID SUGARS
Added sugar is extremely unhealthy. Studies show that it has uniquely harmful effects on metabolic health. Sugar is half glucose, half fructose; and fructose can only be metabolised by the liver in any significant amount. When you eat a lot of refined sugar, the liver gets flooded with fructose, and is forced to turn it all into fat.
Numerous studies have shown that excess sugar, mostly due to the large amounts of fructose, can lead to increased accumulation of fat in the belly.
Some believe that this is the primary mechanism behind sugar’s harmful effects on health; it increases belly fat and liver fat, which leads to insulin resistance and a host of metabolic problems.
Liquid sugar is even worse in this regard. Liquid calories don’t get “registered” by the brain in the same way as solid calories; so when you drink sugar-sweetened beverages, you end up eating more total calories. Studies show that sugar-sweetened beverages are linked to a 60% increased risk of obesity in children per each daily serving. Make a decision to minimise the amount of sugar in your diet, and consider completely eliminating sugary drinks.
Keep in mind that none of this applies to whole fruit, which are extremely healthy, and have plenty of fiber that mitigates the negative effects of fructose. The amount of fructose you get from fruit is negligible, compared to what you get from a diet high in refined sugar.
The bottomline is that excess sugar consumption may be the primary driver of belly fat accumulation.

2: EAT MORE PROTEIN
Protein is the most important macronutrient when it comes to losing weight. It has been shown to reduce cravings by 60%, boost metabolism by 80-100 calories per day, and help you eat up to 441 fewer calories per day.
If weight loss is your goal, then adding protein to your diet is perhaps the single most effective change you can make. Not only will it help you lose, it can also help you avoid re-gaining weight if you ever decide to abandon your weight loss efforts. There is also some evidence that protein is particularly effective against belly fat.
One study has shown that the amount and quality of protein consumed was inversely related to fat in the belly. That is, people who ate more and better protein had much less belly fat. So, make an effort to increase your intake of unprocessed eggs, fish, seafood, meats, poultry and dairy products. These are the best protein sources in the diet.
If you struggle with getting enough protein in your diet, then a quality protein supplement (like whey protein) is a healthy and convenient way to boost your total intake.

3: CUT THE CARBS
Carb restriction is a very effective way to lose fat; this is supported by numerous studies. When people cut carbs, their appetite goes down, and they lose weight. Over 20 randomised controlled trials have now shown that low-carb diets lead to 2-3 times more weight loss than low-fat diets.
This is true, even when the low-carb groups are allowed to eat as much as they want, while the low-fat groups are calorie-restricted and hungry. Low-carb diets also lead to quick reductions in water weight, which give people near instant results. A major difference on the scale is often seen within a few days.
There are also studies comparing low-carb and low-fat diets, showing that low-carb diets specifically target the fat in the belly and around the organs and liver. What this means is that a particularly high proportion of the fat lost on a low-carb diet is the dangerous and disease promoting abdominal fat. Just avoiding the refined carbs (white breads, pastas, etc) should be sufficient, especially if you keep your protein high.
