what happens if you’re in a calorie deficit when you have no fat to lose?

So our bodies aren’t perfect about burning fat. They generally also burn muscle at the same time. And if we have no more fat reserves left, our bodies will continue to burn our muscle tissue, causing us to get weaker as we start converting the tissues that our body uses to survive into energy to keep our heart pumping.
Eventually, this would lead to death.

Catabolysis. Your body resorts to protein for energy. It is really inefficient (producing something like an eighth the energy of ketosis, which is burning fat for energy). Muscle tissue degrades first as your body attempts to preserve things necessary for survival. Eventually your organ, which are smooth muscle, begin to breakdown as well. This is eventually fatal.

In short, your body starts converting muscle (protein) into energy. After a certain point (>4 weeks of no food), your muscles (including your heart) has atrophied (in this case, been used as energy) to the point that you’re too weak to sustain yourself; protein is essential for cell production and when the protein is gone, so is cell production.
No one dies purely from starving, what they die from is typically infection (due to the body not having enough energy to fight off infections/viruses) or heart failure (due to said muscle atrophy).
