“Can exercising help obesity?”

It can, and it is great for cardiovascular health and endorphin production. I find that 80% is nutrition and 20% is exercise to lose weight. Eating healthy protein and keeping carbohydrates low is the best math. To get more specific for each person, I suggest that they find a good bariatric physician near them to make sure they are using the right tools to achieve their goals. A good reference is to visit: https://obesitymedicine.org/find-obesity-treatment/ and find a bariatric doctor near you.
