Go to the gym.
Find someone on a treadmill.
Have them wear your Fitbit.
You now get all of their gains.

I walk 12,000 steps per day for 4/5 days per week.

Here are a few not so well known facts related to weight gain and weight loss:

* What you intake and the intervals in which you intake are equally or even more important than how much you intake.
* Key hormone for both fat-related weight gain and weight loss is Insulin.
* You don't gain "more fat", but rather, you fill up your fat cells. Think of it like a plastic bag: Filling the bag makes the bag heavier, but it does not increase the the amount of plastic that makes up the bag.

Since the mainstream are mostly ignorant or like to obfuscate these details - you might consider it worthless trivia and disregard it like any other responsible member of "our" democracy.
