<p>I feel bad for your S and for you about this missypie. I’m not sure you’ll get a lot of help for him on this thread since his place in life now is different from most of us here plus he has the other issues you mentioned. </p>
<p>Usually for most of the people the age of the posters here, especially the males, the motivation is health as we see peers in our own age group start getting hit with heart attacks, strokes, mobility issues, and the like. For women appearance seems to be a major motivator. </p>
<p>At your S’s age the motivations can be to attract a mate, perform better in various sports including more solitary ones such as cycling, walking, swimming, hiking, etc., and sometimes just how they feel. </p>
<p>You can only do what you can do. This includes education of him in this area, not arguing with him about it which is generally counter-productive, trying to get him to see some professional help in this area including perhaps a psychologist to help him understand why he’s doing what he’s doing (I know you’ve tried), modeling proper eating habits and weight control by other members of the household, and limiting unhealthy eating opportunities in the house for him. I know the latter is tough since he can bring stuff home from the grocery, hit FF places, hide stuff, but that’s not a reason to give up on this front. There should never be sausages in the house for example since a sausage isn’t healthy for anyone. If nothing else he might not just assume it’s normal for a house to have a lot of this type of food readily available and it makes it a bigger hassle to get those late night snacks (or major meals in his case) so he may skip some or go for something a bit healthier instead if that’s all that’s in the house.</p>
<p>At the end of the day though there’s only so much you can do but you can still do what you can.</p>
