I agree with the above.
But when I really feel a deficit (such as eating a light breakfast, doing an hour of weight training and needing to get through to lunch) I do take a low calorie protein shake.
It ain't cheap, but it does the job. My favorite is called Isoflex.
It's not easy to retain, let alone build, muscle on a calorie restricted diet. I have just about done it on my journey.
I now eat a lot of lean protein every day to fuel my exercise. But earlier on I ate less to lose weight.
It's a fine balance and you need to be careful depending on what your goals are.
