"I have to eat until I can't move" that reminds me of one of my friend who use to say "aaja naito le kalkatta dekhne gari khaiyo".... no idea what does that mean... well i won't say its impossible to eat regular nepali dal bhat and stay fit coz i have seen dudes back in Nepal completely relying on dal bhat and getting to shape... but for sure you'll need to work out like crazy... in simple words you'll need to burn more calories than you consume... if you are burning 1000 calories a day and consuming 2000 calories you might get bigger but won't get six packs or ripped body.... the best eating habit I found is eating small portion 6-7 times a day... these are my thougths may be I am wrong...
