I guess the saying, everybody is different applies here.<p>I still remember the days when I could eat 3 - 4 pound of beef, along side with mesh potato, or 12 inch Pizza, or whole bucket ( 10pcs ) KFC, per meal! And these meals would come with Coke as well. in Tea time i will eat Ice Cream, eat lots of yogurt etc.<p>I dont do lots of sports, may be once a week maximum. Otherwise I just sit down playing World of Warcraft or watching TV.<p>All while I don&#x27;t gain 1 pound of weight! I had a VERY hard time gaining weight when I was in the age of 16 - 22. I even tried those weight gainer and protein. And does&#x27;t work<p>Now that i am a lot older, trying to lose some weight, I find out a lot of these theories simply don&#x27;t make sense when i was younger. If you are what you eat, then I was definitely eating 4000+ calories per day and not getting Fat.<p>I think, everybody has a different body type that reacts differently.
