Mio is what I switched to also.
This is what I wanted to start doing, and adding in taking a sauna and swimming 3-4 times per week. Had an ear infection for a month and now almost recovered from Covid from last Friday. I put on 3-5 lbs per year fro 20 years. And just want it off now.
i break up the walks as such: 1.75m in the morning (at 10:15), then one in the evening for 1.25m (at 7:15).
i do the IF from 7p -11a, so when i get back from the morning walk (usually 26 mins., so roughly 10:45) i do some cardio (jump rope or speed bag foot drills), then break the fast at 11.
usually fish or lean grilled or roasted chicken ... fruits/lo fat yogurt/nuts/veg - loving my grilled eggplant & zucchini this time of year.
will do flavored seltzer during day, along with coffee/tea ... light protein bar or two (KIND breakfast bars are my go-to) 'til dinner.
dinner is always abundant greens with what i had the day previous for lunch, but i try to switch it up best i can.
the results are quick, and very sustainsble once you relearn all you "knew" about nutrition and feeding yerself.
i do allow myself 2 cheat Sundays per month now, seeing as how am firmly in cruise control/maintenance atm ... but i really don't go too far off the reservation ... mostly CHEESE with my pasta, or some pizza.
if you incorporate swimming you'll be able to cut the walking back to maybe only 1 or 2m per day, pending how much water time you log.
oh, and along with the weight loss benefits, my bp is now consistently in the 110/70 range, and my resting bpm is barely 60 on most days.
that heart, man ... keep it humming!
go get(z) 'em!
