yes naturopath can help your dh , i was over 154kgs a few years ago , seen a few doctors and naturopaths , yes they help . now i down to 118 and slowly losing weight. often men can lose weight quickly , but what i hated was the word diet , so i can the process a life change for the better . i ate a lot of stir frys , cut the meat real small looks like there a lot in there . fruit banannas are a good help energy wise . ate a lot of chicken and fish its better for health , gut a lot of red meat out of diet . soft drinks and take food out , you will be surprize how much wieght you lose when u stop eating this . good luck with dh and let us know how is going . if he needs a firend to talk to , iam here if hes needs to , best wishes
