No, sit-ups are the best way to lose fat. You may not be effective because you don't have enough exercise time and intensity. I have some other methods here. Look at them.

1. Change your eating habits.

Don't sit down or sleep on your stomach immediately after eating. It's best to stand all the time. You can choose to take a walk or pack some things. In addition to reducing fat accumulation, it can also help digestion. Because within 30 minutes after a meal, if you are still, it is most likely to form abdominal fat.

2. Walking posture and sitting posture should be correct;

When you walk, you should hold your head high and swing your arms. Always hold your arms on your chest. Abdominal muscles are weak and easy to protrude. Moreover, walking with swinging arms not only consumes a lot of energy, but also looks particularly energetic. When you sit down, you should also straighten your back, don't bend over, and don't straighten your abdomen, so that you can exercise your abdominal muscles and make them strong and not easy to collapse.

3. Cooperate with sports;

Shake the hula hoop or do sit-ups and stretching exercises at any time, which can gradually eliminate abdominal fat, make abdominal muscles stronger and make it more difficult to accumulate fat.

Eat healthy food

Yogurt and fermented milk can activate substances necessary for digestion and help improve the intestinal microbial system, thus preventing abdominal bulge.

Drink less carbonated drinks and chew less gum.

When drinking aerated drinks or chewing gum, you will swallow a lot of air, especially the polyols contained in chewing gum, which will not be digested by the small intestine.

I hope this knowledge can help you, but I personally think doing sit-ups and hula hoops is the most useful, because that's how I lost weight. Of course, the diet is also a little controlled.
