I have been on no eating plan for a long time, and a week ago just began a new plan I designed based on a few different factors including some relatively recent research, and some issues with my now fully menopausal old body.
One element of this is that it is two weeks in ‘reduction’ mode (2x 40+ hour fasts, the rest 17/7 IF, all keto, all lowcal {for me}); then two weeks in ‘maintenance’ mode (17/7 all, but no carb limit, a min/max calorie requirement, and a lot more milk, fruit, veggies and starch), then back again.
Since I carry a lot of water for carbs it’ll be crazy up/down from that I know, that’s the only part I’m worried about. For the rest though, it will be interesting to see how a sudden dive into the fruits-veggies-potatoes world will affect my attempts at fat loss. The water add/remove of going on/off full keto, may add confusion in the short term, but I think might make things clearer in the longer term (as weight should go down in both cycles, it’s just they can only be compared against the prior cycles of their own kind).
I have spent many years doing a lot of work to heal my liver, after meditative visions showed me it horrifically cirrhotic – given my size, for years, that is not even surprising. I love my liver. And I’m a liposomal silymarin fan which I think is hugely healing, I will continue that supplement. Here’s hoping the great widening of my menu is not destructive.
When I am not on an eating plan I mostly starve from lack of appetite, don’t move from lack of energy, then eventually freak out and eat everything horrible for three days because body thinks I’m starving. So I have to be on SOME kind of eating plan to keep my intake even halfway sane. Pretty sure even eating the carby side of the cycle would be better for me than no plan at all, but since both hard keto and high carb make me feel pretty crappy after a few weeks (this was never true for keto until well into menopause I might add, go figure), I’m hoping the back & forth might front-run those issues as well.
I am eating pineapple in my hot spicy thai-inspired stir fry whether it kills me or not. Hopefully it will not.
