You need a certain level of protein (1g per 1lb of LBM) to maintain muscle mass, going below this has obvious repercussions.
You also need a certain level of dietry fat (0.4-0.5g of total body weight) in order to help vitamin absorbtion and hormone creation/balance.
So the total calories from your required protein/fat intake would be your absolute minimum calorific intake for the day.
For me I need approx 145g of protein (580 calories) and 80g of fat (720 calories) so an absolute minimum healthy calorific intake of 1300 calories.

Well, first of all you will probably feel hungry and have less energy.
Second, even with a high protein diet if you go very low on your intake you will start losing muscle 'cause your body will use it as fuel.
And you should not cut back too much on fat either - your testosterone level will go too low and your body uses the fat to transport nutrients through your bloodstream.
Have you read the stickie about macronutritional needs here in the forum? You should.
Try to calculate your fat and protein need while on a cut and just go easy on the carbs.
Aim for 10 to 20% below caloric maintance level to safely lose weight.
Living on a very low calorie diet for a long time period will do more harm to your body than good.
There are also many different options like keto-diet, et cetera so you have to find out what fits your needs.
