I’d like to know if it’s possible to know “how much weight do I lose or gain per calorie eaten in excess or under”.

I tried to work this out myself, please correct me if I’m wrong:

I know that if I eat 900 Kcal per day, I lose 2.1Kg per week (300g per day).
I know that my TDEE (Total Daily Energy Expenditure) is 2563 Kcal.
2563-900 = 1663Kcal

So my assumption is that if one day I eat 1663Kcal over my TDEE, I’d put on 300g.

If that’s correct, doing a rule of 3, this is how much I would put on if I ate double my TDEE:
1663Kcal 300g
2653Kcal 479g (ie: 2653Kcal “extra”)

If I eat triple my TDEE:

2653*2 = 5306

1663Kcal 300g
5306Kcal 957g

…this means that if I eat triple my TDEE I’ll put on roughly 957 grams.

If I’m not correct, is there any online calculator to work this out?

I’d welcome any opinions.

My weight 77Kg
Height 186cm
Age: 58
