What is your daily diet?

[NoLove]

You should maybe take a look at fats.

Also I'm not sure what your goals are or why you are cutting but 3 pounds per day is insane. 3 pounds per week is too much. The healthiest range for losing weight to maintain your muscle base is 1-2 pounds a week, unless you are massively overweight, which it doesn't sound like you are.

Why are you being so strict on your diet? Why not keep your calorie intake around the same but eat some more interesting foods?

I have cut weight both ways - one time eating 100% "clean" foods and the other keeping to a calorie limit but eating more interesting food choices. It was a lot less painful the second time round. A lot less.

Im not really working towards anything goal wise. I do boxing training (i train myself as ive got no gym near me), but I have kind of an extremist personality. I'll either be very strict or binge on junk food.

But, to confirm what you say is true, I have woke up some mornings looking like Ive lost a lot of muscle, literally overnight.
