Here’s how to start losing belly fat fast.
1. Lose belly fat by cutting out sugar

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.
2. Lose belly fat by eating more protein

Protein is one macronutrient that can really help fight belly fat.
When you eat more protein, it keeps you fuller longer and reduces the hunger hormone ghrelin, helping you slash the total calories you consume in a day.
High-protein meals, with 20 to 30 grams of protein each, can also help you burn more calories by raising the body’s metabolic rate.
Eat up to three protein-rich meals a day to keep your appetite and cravings in check.
Good sources of protein include poultry, lean meat, eggs, fresh-caught fish and other seafood, cottage cheese, and yogurt.
3. Lose belly fat by adding more fibre

Getting more fiber into your diet, especially soluble fiber found in oats, chia seeds, legumes, vegetables, and fruits, can help reduce fat accumulation in the abdominal area.
Psyllium husk is another great source of fiber—and has zero calories.
Fiber swells up with water, increasing the bulk of your stomach contents and giving you a feeling of fullness.
It also reduces fat absorption from food by binding with bile acids required for the digestion of dietary fats.
Fiber can also bind with sugars and other carbohydrates, delaying or reducing their absorption into the bloodstream.
