Is it possible to gain fat on a calorie deficit?

[nickorette]

say under the worst possible conditions. Like say your maintenace was 2800 cals and you ate one meal of lard of 2600 calories. And drank little water.

This is purely hypothetical. I'm just wondering if it is possible if someone tried really hard, lol.

Thermodynamics.

Search it.

Not saying recomposition for the worst isn't possible.

Adding tissue though.

No.
