Increase protein intake
Protein offers the body building blocks to repair and grow muscle, and it also helps a person feel fuller for longer.
A small 2012 study found that people who consumed high-quality proteins, such as milk, eggs, and beef, had a lower percentage of abdominal fat.

Do exercises while standing, not sitting
People should opt to stand when lifting weights or doing resistance training. Standing while performing certain movements, such as bicep curls, can help a person engage their core as they lift.
This engagement can help strengthen the core muscles and trim the stomach area.
Limit refined carbs
Carbohydrates are a source of energy for the body, but not all carbs are equally healthful. The body transforms certain carbs, such as white bread and white pasta, into glucose. When a person consumes more glucose than is necessary, the body stores the excess as fat.
A person looking to reduce the amount of fat around their midsection should limit their consumption of refined carbs.
As carbs are essential for energy, people should still eat healthful, whole-grain varieties.
