This diet you have posted is just a regular ol diet.Nothing special but will work fine. A tad low on calories so you may feel washed up. I would cut some of the carb calories down and up the protein to help ensure you don't loose muscle. I typically cut like this. I weigh 212lb right now, so I just go around 1.5 grams of protein per lb that I weigh.
So that is 300 grams of protein. I keep carbs low 70 grams which is 280 calories. My fat intake from clarified butter, coconut oil, and some olive oil and egg yolks and beef is 40 grams and another 270 calories. This puts me at 1750 calories. This puts me at 600 calories below maintenance.It maintains muscle and tears into bodyfat.
This puts me at an unusual breakdown of 74% Protein;16% carb;10%fat
