Every time yes. I always spent some time fat adapting first. A few times I took full RDA of vitamins and minerals and always take EFA’s anyway (plus would also consume a small amount of fish as part of the protein allowance). Once occasion I didn’t supplement with V&M’s apart from magnesium. Didn’t notice any particular difference.
But also, I was part of a group of people who did this WOE and my experience was not at all uncommon. Weight loss happened for all of us. BUT the only people that didn’t gain back were the peeps that continued a very extreme caloric restriction. So during the PSMF it would be 600-800 cals and then after they’d be on 1000-1200 for maintenance. I’ve not kept track of all those people since then, but I don’t believe that kind of perpetual caloric restriction is sustainable forever.
Coming off the PSMF I have always returned to LC or keto. I’ve keto’d on and off since 2006.
I have heard of the PSMF working well for quite a few guys (not sure about longer term though) however, it was a real struggle for myself and other women who attempted it. And I believe it harmed my metabolism. Which in all honesty, has taken many beatings anyway over my adult life, i’m not going to hang that solely on PSMF.
Interestingly, I didn’t experience the same metabolic damage just fat fasting (I also don’t believe I lost LBM fat fasting). For context, I lift weights, and have done on and off since my teens (i’m now 38) and I always, always, always have some kind of weight lifting regimen if i’m trying to lose body fat, to help preserve (not necessarily build) LBM.
