Just pick for food, sack the fizzy drinks and eat what you like or fancy. I am 5,10 and 9 stone and drink like a fish but I can eat what I like whenever.
Get on the fish, eggs, bacon, peanut butter and rice.(Not altogether) I am lucky as I cannot gain weight but I understand some people just put weight on.
No fizzy drinks zero sugar or not. Water, milk (full fat) and don't stress about it we all different.
Exercise is a myth it just makes you more hungry as you burn energy.
Exercise is a myth, drinks like a fish, recommends eating bacon? You may be thin but that’s not healthy.
