So so your body needs fats and sugars just in moderation being young and skinny mate I would just eat what ever I could get in my mouth , when I was younger I had the opposite problem I was a chunky kid so I had to watch calories and fats to trim down but from talking to some of the bigger chaps at the gym there main issue is being able to consume t calories they need ... full fat milk is a must iv found it’s high in protein,calcium and natural sugars and relatively cheap , I’m 6ft and 185lbs and I still drink a pint of milk every morning out of habit now , yiur right in saying soda and chips are still bad but if I was you I’d try and get fat while working out , build your frame to bulk kind of thingI may try to run on grass then.
But isn’t soda and chips and stuff like that still bad?
