As a rough estimate id say around about 30 points a day. But rather than having 3 good meals out of that hed skip brekkie, have something greasy off the snack van near his work and then come home and have sausage and chips. Or potato wedges etc. I think its just changing the way his mind works and the old habits. This week so far everyday hes had brekkie and has taken something with him to work. So far so good.
