As long as you exercise, you can lose weight, which is nothing more than a matter of degree.
Even if you don't exercise, you can lose weight by increasing daily activities.
A neat diet is popular abroad, and the so-called neatness is actually "non-exercise heat production". A person's daily calorie consumption is three: resting metabolic rate, food thermal effect and activity thermal effect. If you want to increase calorie consumption, you can only make a fuss about these three projects. The thermal effect of activity, except exercise, is called neatness.
We usually cook, wash clothes, sweep the floor, clean the table, jump, stand and squat, and so on. The calories we consume are called net calories. Don't underestimate the heat consumption of this part. Experiments show that an active and tidy diet, such as sitting less and standing more, walking less and standing more, taking less elevators, taking less cars, doing more housework and working more, can make an average adult man of medium height consume 350-400 kilocalories a day. Adults need to jog at 10 km/h for more than half an hour to consume so many calories directly through exercise.
Any activity will consume energy, and energy, whether direct or indirect, will play a role in consuming fat. So as long as you move, it will help you lose weight. Don't worry about sweating and fatigue after exercise. Just keep exercising and eat properly.
