It may be that your diet is unscientific, you eat too many high-calorie foods, and the calories consumed by running make up, which will not produce the effect of calorie vacancy and fail to achieve the goal of losing weight.

I suggest you eat less oil and salt, more fiber food, less refined flour and rice, and more high-protein and low-fat food. Vegetables should account for one-third of your daily diet, not less than 500 grams, and it is best not to skip meals at night. Keep your running strength, take your time and don't lose heart. It will always work.
