I think you're both trying to say similar things but slightly differently.
You do affect your short term weight loss by exercising and building muscle. You may retain water and not lose pounds. However, in the long term as you gain more muscle you burn fat better and lose more weight. Additionally you tone up and should lose inches even if you're not losing pounds at first. Just make sure you drink loads of water to make up for the retention. Don't forget your muscles keep working for at least 24 if not 48 hrs after training and you need more water throughout this time.
So a good workout should include both cardio and weights. And OP, your husband should not need protein shakes unless he is seriously body building. Theyre a waste of syns unless he really needs to bulk up and body build. Just make sure that you do eat some protein in the 45mins - 1hr after your exercise - preferably something "clean" like meat or cheese etc.
Hope that helps! X
