For anyone thinking that if they exercise then they will lose weight then think again. nytimes.com/2018/04/11/well... presents latest research confirming that it does not. In this case they measured rats who exercised more and less - and monitored their weight. Either way there was little significant change in weight.
The researchers argue that rats who exercise more eat more, and those that exercise less eat less. I think the same can be said largely for humans. In my own case I remember playing squash weekly in my 20's and feeling so good about it I had a regular pint or so afterwards.
So yes, exercise may improve how you look and feel, but don't expect that to register very much on the weighing scales.
