Need to find/lose 3kg...

Weighed the bike this weekend, it is 13.5kg all up. My old bike is only 10.5kg. I guess that what you get when add 5.75” of rear suspension, a beefier frame, and an extra 50mm of travel up front. So I need to find/lose 3kg so that we have equilibrium in the universe. Can’t remove it from the bike, so will need to lose it from my fat __, so back on a diet and more exercise for me.
