You have a natural high metabolism. I used to deal with people like you while I was working at a GNC for three years.
Up your calories to like 2500 and eat a lot of fast carbs. (potato, white rice, white bread, sugar etc.) with each meal and eat 3 meals a day instead of 6. That'll slow down your metabolism a little and help you gain the weight.
Hmm ...
A average (good) day for me would be something like:
Eggs and toast for breakfast.
With it some tea loaded with sugar
Then rice/pasta with meat ... alot of meat
Chocolate cake/ice cream and sometimes both (I say sometimes, i lie and mean all the time)
Then if i get peckish, go kebab or get indian
Come back home and my mom is cooking something else for me.
I do bake cookies and cakes for myself when i cba.
In between all of those i am munching on crisps, chocolate, sweet.
What am i doing wrong?
