shower thought: a moderate deficit is

I just recently occured to me that could use the formula used to calculate one's TDEE backwards. here me out.

Current TDEE is estimated at 2320 using this formula:

tdee = tdee_factor * (66 + 13.7 * weight_kg + 5 * height_cm - 6.8 * age_years)

If I would eat 2000 consistently, what weight could I expect to have? solving the above equation for weight_kg and using my data, I arrive at 92 kg.

If I would eat 1800 consistently, what weight could I expect to have? solving the above equation for weight_kg and using my data, I arrive at 80 kg.

My takeaway here is: today's deficit can be tomorrow's maintenance weight.

And me being overweight currently is actually me eating way more than what my body needs consistently for years.
