Fat loss depends not only on exercise but also on how the body burns calories at different times. Walking on an empty stomach is believed to help burn more fat.
When walking on an empty stomach, the process of breaking down excess fat is more intense, thereby releasing fatty acids into the bloodstream for muscle use. Therefore, with the same exercise, the body can burn more fat. It's better to exercise when you're hungry, according to the health website Healthline (USA).

Burning a lot of fat during exercise doesn't necessarily mean losing a lot of fat
A common misconception is that burning more fat during exercise doesn't necessarily mean greater long-term fat loss. Studies show that exercising on an empty stomach increases the rate at which fat is mobilized for energy. However, the overall body fat loss over time is not significantly different from exercising after eating.
The reason is that the body has a compensatory mechanism. After exercising, we tend to be hungrier, eat more, or our bodies burn less fat at other times of the day. Therefore, the determining factor is still the total number of calories burned and consumed throughout the day, not just from one workout session.
Eating a balanced diet combined with regular walking yields more noticeable results
Therefore, a proper diet combined with regular walking will yield far more noticeable results than simply changing the timing of exercise. Besides burning fat, walking on an empty stomach can offer several metabolic benefits. Much scientific evidence suggests that exercising while hungry can improve insulin sensitivity.
Not everyone is suited to walking on an empty stomach
It's important to note that walking on an empty stomach isn't suitable for everyone. Some people may feel tired, dizzy, or lack energy during exercise. This can make the workout less effective.
Furthermore, if the energy deficit persists, the body may begin to use protein from muscle tissue. This is not beneficial for long-term health. People with blood sugar problems need to be cautious because of the risk of hypoglycemia.
Walking on an empty stomach is suitable for people in good physical condition. This form of exercise should be done at a light to moderate intensity, such as a leisurely walk for 20-40 minutes before breakfast, according to Healthline.
