Every day you’ll see another post about jumpstarting your metabolism.
You can’t give your metabolism a sudden jumpstart that turns you into a fat-burning, super lean fitness monster.
You can, however, live a less shitty lifestyle that causes you to burn more energy more quickly.
There aren’t quick fixes with immediate results—that’s why they call it “changing your lifestyle.”
The word “metabolism” just refers to all of the chemical reactions going on in your body at the same time, including digestion but also turning sugars into energy, building proteins, and doing the rest of the chemistry that keeps you alive.
Your body combines all these processes to sustain itself and to maintain homeostasis: a constant state of fuel in, energy and waste out, keeping the proper levels of the chemicals you need in check.
