My son has started an apprenticeship in joinery, he's currently renovating a house. It's physically demanding out from 06:00-18:30. He takes a packed lunch of chicken sandwiches crisps and a biscuit.For tea he might have mac and cheese or if he doesn't like what I've made he'll have jacket spud with beans and cheese.
My concern is that he has lost weight since he started and he is already very tall and slim and really can't afford to lose weight.
Please give me some advice on how best to put weight back on. He is fussy and allergic to nuts.
TIA
