I am way too skinny for my liking though, but gaining weight has always been hard for me, even though I don't pay attention ( eg. eat what I want whenever I want) to what I eat at all.
As you can understand I'm stumped as to why so many people are overweight, as in my experience it's nearly impossible to gain weight even when being a lazy **** and eating a lot of junkfood.
The main problem is actually my laziness, I cba to get something to eat downstairs when I feel like I could eat something often or I'm so much ''into games'' that I forget I'm hungry. I just don't think of eating and because of that I eat too little.
