Does fasting reduce belly fat? (2024)

Belly fat, also known as visceral fat, is not only unsightly, but also leads to many health risks, such as diabetes, heart disease or obesity. Many people choose intermittent fasting to reduce their excess belly fat. However, does this eating pattern really work as expected?

Most of us have a certain amount of belly fat, even those with flat abs. However, having too much belly fat affects your health in different ways.
Some fat is located just under your skin, others may be deeper inside or around your heart, liver, lungs and other organs. The deeper fats, called visceral fat, act as a cushion, helping to support the organs in the body.
In fact, our body only needs a small amount of visceral fat. Too much of this fat can lead to dangerous conditions like high blood pressure, heart disease, type 2 diabetes, dementia, colon and breast cancer.
When your weight increases beyond the allowable limit, the body will start to store fat in certain areas, especially the organs around the heart. Even in thin people, they can still store a lot of visceral fat. The amount of excess fat you have will depend on factors such as your genes, lifestyle, and physical activity level.
Visceral fat tends to occur more in people who do not exercise regularly or have an unhealthy diet. Therefore, whether you are thin or overweight, it is important to participate in sports activities every day to avoid storing belly fat or other unhealthy fats in the body.

The most accurate way to help you determine how much belly fat or visceral fat you have is a CT or MRI scan. In addition to the above methods, you can also check your belly fat at home through a tape measure.
You can take a measuring tape, then wrap it around your waist and check your waist circumference. For the most accurate results, you should stand upright when measuring. For women, the ideal waist size is under 35 inches and less than 40 inches if you're a man.

The empty stores of glucose or sugar burn fat and create chemical byproducts, called ketones. This substance will circulate throughout the body, helping to improve insulin sensitivity, nourish the brain and reduce inflammation. In addition, blood levels of sodium and the compound TMAO (which is linked to heart disease) also plummeted, while a red blood cell count increased, which promotes heart health.
Furthermore, brain-derived neurotrophic factor (BDNF), a protein essential for the healthy maintenance of nerve cells, spiked. Meanwhile, cells switch from an active to a resting state, repairing and cleaning up faulty mitochondria (the cell's energy-producing furnace) and reducing oxidative stress (the cell damage that causes cell damage). aging tissue).
When we eat again, the cells have adapted and better use fats, proteins and carbs. Nutrition experts say that switching back and forth between fasting and eating again can bring many health benefits, including weight loss, reducing belly fat.
