Default cons of the regular IF

ive read that some ppl approach IF with more of a random schedule, i.e., intermittent, intermittent fasting.

besides the fact that a regular IF schedule doesn't really mimic HG patterns, are there health drawbacks (e.g., slower metabolism?) with a daily IF routine, such as the fast-5 (or for me, the slowish-8) that im overlooking?

I hate to say it but I've found my metabolism to have slowed down quite a bit.

The question we have to ask ourselves now is, is having a slower metabolism a bad thing? You could easily look at in a different direction that now your metabolism is more efficient...

yeah, that's exactly why i asked. got on the scale today at the gym - up another 5 lbs suposedly. a little surprised, considering body comp is pretty good and metcon performance hasn't suffered. ive been sticking to ~14 blks P/C (and a TON of fat), so def a little surprised. perhaps im not as dialed in with food as i think....

don't really care too much about weight, but at 6 ft, 185 lbs (15% bf???).... getting through 100 pull-up type workouts.... takes a while.

I'm in the same boat. Pulling in about 2300cal and have been steadily gaining. I've also ditched the multi-meal ideology too. On fast days I'll have 1 maybe 2 meals. Eat days I'll eat 3 meals...I'm still a bit skeptical though on the small multi meal=faster metabolism though.

The thing I've noticed is that when you've been following IF for a bit you need less food than you used to. I think some people said it was due to you use less calories for digestion than you used to following the multi-meal approach.

Is this weight measurement in comparison to your last weeks weight?

I've been following IF since January and went from 195 to 185 without cutting my calories too much (then with my wifes surgery and stuff the last few months I'm up past 198) I'm back to clean eating now though and losing weight again. I've actually been wondering about the metabolism thing for a while now as my body temp is a little bit lower than it used to be. I don't think I've lost much if any muscle compared to where I was last year at this time.

You'll need less food to maintain weight...so yes you probably need to cut down on the fat calories....which is a good thing considering now you spend less time eating, still keep the same muscle, burn fat...and oxidize less food creating less free radical damage and slowing down the aging process. Not a bad deal if you ask me!

I'm not sure if the fasting really slows down the metabolism per say. The lowered body temp could be in response to doing less digestion all day long or built in survival mechanism when on a more reduced calorie diet (as seen below from PubMed, which is more on CR but same can be said for IF I am sure)

Indirect calorimetry showed that 24-hr energy expenditure was reduced by approximately 24% during short-term CR. The temporal association between reduced body temperature and energy expenditure suggests that reductions in body temperature relate to the induction of an energy conservation mechanism during CR. These reductions in body temperature and energy expenditure are consistent with findings in rodent studies in which aging rate was retarded by CR, now strengthening the possibility that CR may exert beneficial effects in primates analogous to those observed in rodents.
You also use your food more efficiently so you can assimulate more protein from less grams per day than you are used to. Your themogenesis digestive part of your metabolism is dropping, I think there have been studies to show the T3 levels do not until you start fasting over 2+ days.

Again...all good problems to have considering the health and longevity benefits gained.
