Can confirm that. The very first time I attempted a keto like diet (was actually a PSMF if I recall correctly), I felt so shitty and lightheaded in the first couple days that I bailed and tore into a small pack of cookies. It gets a lot easier though. After going in and out of keto a couple more times, it completely stops being an issue.
