I'm not feeling so good right now. I was under medication, and i guess my stomach wasn't agreeable to it as I kept on puking after I take it. So I have decided to ditch the darned pills and visit my doctor and see if I can get something milder which my tender tummy can handle.
Anyway, prior to me puking my guts out I was actually about 49kg which is pretty impressive for me. Impressive because I didn't really try to devour more than what I usually eat. The only additional 'meals' that I took were cashew nuts and soy bean milk prior to a training session and soy milk again as a post workout drink.
The rest of the time it's the typical day consisting of breakfast, lunch and dinner.
From this little outcome I can conclude that ectomorph me don't really need to stuff myself silly with Big Macs and fries just to get some extra calories in. Eating fairly clean and weight training regularly does the trick. Again, I'd like to emphasize that eating nutrient dense food, and eating clean I.e. Unprocessed food would help you gain mass without gaining too much fat along the way.
At least this is the case for me.
