Try somehow to stick around 2300 - 2400. 1900 is not enough , you will end up losing muscle.
I feel like me and you have been disagreeing a lot Raul...

My bad not meaning to.

Not true... I'm eating that everyday now to lose fat/gain muscle and that's only 100 calories less then my TDEE.

I'm lazy otherwise if I did a little more like an average person it would be about 2300 for my TDEE. It all depends on his size, height, etc. as to what his calories are. But yes for him 1900 isn't enough from the what it looks like. Like Raul said try to stay near you calorie goal.
And to answer your question if you burn the calories then yes you can eat the 500 calories you burnt off. As long as your still eating 100-500 calories less then your TDEE to continue losing weight. Just make sure you don't cut your calories to much. Also, if you're a beginner you can lose fat/gain muscle it's just a slower process. What are you using to figure out you calories? Just curious... I'm not a big fan of Scoobys calorie calculator sense it over estimates calories and under estimates.
