I do it. But mostly for cortisol control. I prefer to split my workload into 2 smaller sessions than one big one when dieting.
BUT in my opinion the mistake is having the mentality of using lifting to lose fat. This leads to too much volume and can actually speed up the muscle loss process. I made that mistake in the past myself and I started to go downhill fast.
When dieting down DO NOT use two-a-days to do more work. Use two-a-days to do the same volume in two session to be fresher and stimulate less cortisol release.
