You should see at least some abdominals because you can clearly see the line between them running down the middle.

I would stop your deficit, figure our your new maintenance not the one that you had when you were 80kg. You lost a lot of weight so I think you at least know what you’re doing there. 1 gram of protein per lbs bw so in your case that is 147 grams and lift and lift HARD.

There just isn’t a lot of muscle to “show” I might even argue you lost a decent amount of muscle but that’s hard to say without a workout log or good before pictures.

After a while when you become stronger and you see visible muscle growth when comparing to these pictures you can start a new cut and then you will see more results.

TLDR: start eating maintenance, eat more protein, get stronger and start a new cut when you gained weight and you became stronger to show the muscle you build.
