I can’t tell if you’re trolling, or just not up to speed.
Maybe an analogy would help.
Dems are always yammering that “tax cuts won’t work” because they see the economy as static, a pie with only so many slices, and that neither businesses nor individuals ever change their behaviour in response to government action.
A diet is the same way: your body doesn’t burn the same set, fixed, exact number of calories every day, independent of what you eat, when you eat it, or your activity.
By changing what you eat, how often, you can fool your body’s adaptive systems, and lose weight in ways conventional wisdom say are impossible.
I’m not trolling, and I understand metabolism.
I have been into fitness and nutrition for 30 years.
I eat mostly vegetables, fish/chicken, and fruits.
I take prebiotics & probiotics.
I lift, sprint, walk, do yoga, meditate/breathing exercises, and sleep minimum 8 hours.
You still need a caloric deficit to lose weight.
I understand ramping calories and re-feeds.
