ugh my DH is the same way and he isn't even 30 yet. I worry about his health all the time.
He mostly drinks only cherry coke or nestea all day long every now and then he might drink milk but he won't touch water or diet!
His food is aweful
He never eats breakfast, often doesn't eat lunch. And his meals are usually a bag of chips or a can of raviolis sometimes straight from the can! When he eats like a sandwich it is usually ham or roastbeef piled high and then more mayo then anything else lol He likes soups alot but I worry about all the sodium in them when that is all he eats. Sometimes he would even get frozen chinese food items that have more sodium then you should have all day and then some lol
He also works at a restaurant where he gets free meals. So that sucks.
I am trying to turn things in a better direction. One I am trying to learn how to cook so I can make meals for him so that he doesn't eat just chips for dinner lol. It is still tough. Like he refused to eat wheat bread at all! But then I made him grilled cheese with it and he ate 3 of them and loved it lol But yet still if I try to get him to eat it allthe time he wont. He can't eat poultry because he has an allergy. And I am not a big meat eater except for poultry lol He hates fruit. But he is ok with some veggies so that isn't bad.
I try to get him to eat some new things and to try healthier options. When I am cooking meals I switch things up to healthier alternatives, low fat, etc... I also add veggies and stuff. The most difficult part is trying to get him to give up soda because it is just such empty wasteful calories and junk
And also trying to get him to watch his portions.
It is tough. I know how it feels to be like that and how I would have died and been angry if anyone had tried to tell me what to do (or even offer suggestions lol) but it does concern me too and our someday kids. His health is important to me. At the same time only he can make the right choices
I think just trying to get healthier options in there and then even if he makes bad unhealthy choices often he is still better off then before. Every small bit helps.
