My dh was doing it. I was as well. I found the first 3 days really hard. I struggle to eat twice a day let alone 6. Dh stopped as it became hard to maintain that sort,of discipline with meal times when at work.

He can't just eat when he wants due to his job. It does work tho and works well. I lost 3 kg in 4 days and I wasn't following g it as perfectly as I should have. Dh lost 10kg in 6 weeks

So yes to answer your question. It does work but you have to remain disciplined.
