i do think the exercise part is important. perhaps not as important as eating properly but still important. people with obesity who exercise and who have a good level of cardiovascular fitness can be as healthy or even healthier than people without obesity who do not exercise. the health benefits are much more than what we can see with a scale. exercise is not entirely without risk (due to overuse injury etc. ) but the benefits always outweigh the risks even in severe obesity.
is it true that exercise is not beneficial to really heavy people until they lose weight and get their metabolism going?
