First of all, you should set a clear goal, such as how many pounds you want to lose and how long it will take to lose weight. Then you should not be too ambitious when setting goals. If you want to have a lot of time in a short time, then you can't.
First of all, you can't go on a diet to lose weight, because dieting is very harmful to your body. Eat these nutritious things for breakfast, such as eggs and milk. As for lunch, seven minutes is enough, and dinner can last for six minutes, and then some vegetables or boiled water are used instead. Try to eat light food, and don't eat those big fish, big meat and greasy things in restaurants. In that case, it will cause a great burden on your stomach, which is not conducive to your weight loss and will cause a lot of fat accumulation.
Actually, you have to lose weight, because you are 40 years old, and of course you don't have time to go to the gym. After all, you have to take care of your children when you go to work, so running is the cheapest and most time-saving exercise. For example, if you live on the 20th floor, you can take the elevator to15th floor and climb the fifth floor. It's the same by bus. Get off at two or three stops in front of the workplace and walk there, which will waste a little time. But if you get up early, you will definitely arrive on time. Many things happen. If you can sit down slowly like this, I believe that one day you will find that your weight has reached your ideal state.
