Secondly, since you have been exercising for more than a year, but you haven't lost weight, it is probably related to your usual eating habits. The influence of obesity gene exists, but the acquired factors also play a great role. Your family is like this, and it is more likely to be caused by diet. Just because you insist on exercise, you won't be strict about your diet. In that case, of course you won't succeed! I suggest you eat less greasy and spicy food and more light and nutritious food, such as vegetables, fruits and milk.
Finally, it's not that you can lose weight by exercising. The key is self-confidence and persistence. You should believe that you can lose weight, and it is more effective to exercise for 40 minutes every morning than to exercise three or four times a week. Besides, you don't have to waste money to hire a coach. You can direct yourself. Some simple aerobic exercises are very effective for losing weight, such as jogging and skipping rope. You can try.
All right, that's all. I want you to take action now. I believe you can lose weight successfully! Good luck ~
