Thankyou for the advice….he is also lactose intolerant so finding it hard to add calories to everything…he has a bottle of fortisip daily which contains 300 calories but also 13 gms of sugar which has been causing dumping, which certainly doesn’t help with weight loss ! I add protein, cheese he can tolerate and butter does help but is still slowly loosing…says he doesn’t feel physically weak so that’s good…thankyou so much for your answer x
