Eat less --> live longer?

Today I learnt something very interesting in my lecture, indirectly. According to researches done, one that eats more will have shorter longetivity than those that eat less. Weird huh? So, my family should be thankful for being small-eater??

Reason? According to the metabolic pathway above, our body has this molecule NAD that assists in producing ATP (energy) through glycolysis everytime we eat (each molecule of glucose). The more we eat, the more NADs are used up to metabolize those glucose molecules, thus less NADs are left to activate the Sir2 and hence, the silencing function will decrease, so the longetivity becomes shorter lor and vice versa. As simple as that.

Interesting huh? Grins. But readers, I don't hope to see skeletons anaroxic skinny friends walking around and then start quoting me saying, "Mun said that if we eat more, we'll have shorter life. So, if we don't eat sure have longer life and good also, can diet." It's a BIG NO NO! Please eat, just that don't over eat especially those high-caloried food.

Be encouraged, be blessed and feel loved. Till then, signing OFF.
