although research suggests that people who stop exercising gain more weight over time than people who stay active everyone is different. exercise especially the type that strengthens the body helps build muscle which weighs more than fat. after exercise is stopped there is some lean tissue loss. people who stop exercising also tend to eat the same (or more) calories resulting in eventual weight gain. but you might be different and actually eat less which could be another reason you lose weight. i always recommend exercise for people who want to gain weight i n a healthy way. because exercise is healthy and keeps weight on you it makes sense to keep it up. best of health to you!
26 yrs m 60kg 172cm. problem: i lose weight if i don't do exercise. i have always been a thin person. i have gastritis (not severe). i don't do so much exercise not regularly. but i tend to lose more weight if i stop doing exercise which i think is abnormal because other people gain weight when they don't do exercise. i want to know what could be the cause. i think my diet and way of living is normal.
