1. Irregular diet: Even if you go to the gym to exercise every day, it is difficult to lose weight if you eat unhealthy or consume too many calories.
2. Increase muscle mass: If you increase muscle mass during exercise, your weight may not drop, but your body may become more compact and tangible.
3. Hydration: If you are dehydrated, your weight may be high. Drink more water, you may lose weight, but it doesn't necessarily mean you are losing fat.
4. Exercise intensity and frequency: If your exercise intensity and frequency are not high enough, or your exercise time is not long enough, it is difficult to lose weight.
5. Body metabolic rate: Everyone's body metabolic rate is different. If your metabolic rate is high, you need more calories to maintain your weight.
Therefore, if you want to lose weight, you need to comprehensively consider your diet, exercise intensity and frequency, hydration status, body metabolic rate and other factors. At the same time, I suggest you be patient, keep exercising and keep a healthy lifestyle, so that you can see lasting results.
