I'm taking a brief hiatus from fasting after hitting a plateau hard at the start of this year. I've lost about 29.2 lbs, my goal was 30, but fuck I can't seem to lose another 8 tenths. I've actually gained 5 lbs in like two weeks without changing my diet, fasting or eating habits, so I think something is going on with my digestion and I need to normalize for a bit. Maybe a couple weeks off then back on the diet, as it has seemed to work very well for me for a variety of reasons...
Were you doing a 16/8 fast 7 days a week? Good job on the weight loss!

Thanks. I have been doing 5;2 for a year. Started Jan 4. I had surgery in November which seemed to fuck everything up, but then after recovery I started losing again only to plateau in Feb. Again, I feel like I ate a 48oz ribeye and it's just sitting in my colon, so maybe I've got a parasite or something.

Goddammit. Now I'm hungry for ribeye...

Are you doing a high protein/low carb diet, or just limiting your calorie intake? I know when I have a heavy week of a mostly protein diet & nothing moving as I'd like, I'll go out for Mexican food on a Friday or Saturday night. Beers, tequila, chips/guac and whatever else will fit, gets me going quite nicely the following morning. Rinse & repeat. Then again a 48oz ribeye does sound good!

what about adding or increasing your exercise, and returning to a healthy diet?

On my 2 days, I eat less than 600 calories. I usually skip breakfast and eat something exceptionally small- a cup of light soup or crudite and hummus. On my 5 days I eat whatever I want. It is entirely possible or likely that I have simply been overindulging in microbrew on some of those nights.

Honestly, that might be why I'm plateauing. I tend to notice a brief plateau as I build up the "miles" but then I start losing again. It hasn't really happened in the last month, but I might also be reaching equilibrium....maybe I'm building muscle as fast as I'm losing weight, and can't build more muscle without putting more weight on. While I really want to hit my weight goal, I'm also happy having lost 4" off the waist, 25 comfortable pounds, and being way stronger than I was when I started....

Unfortunately the beers don't help. I stoped drinking all together on the weekdays & keep it to about 1200-1800 calories a day. Whats interesting, since I've been hitting the weights harder 6-7 days a week, I haven't lost any weight but dropped from a 36 waist to a 34 & gained muscle weight. I'm about 215lbs now @ 6'. When I was working out 2-4 times a week and not watching my diet my heaviest was 210lbs, but felt lethargic. Back in 2015 I did the South Beach diet and dropped down to 178lbs. I'm not even noticing the extra weight this time around, its kinda cool.

I’m going to break my fast tomorrow morning at 60 hours. Food sounds good so I shall eat.

In other news, amidst all this madness I convinced my wife to try the CGM! The sensor is warming up now, having been inserted in her arm. I’m curious to see how she responds to carbs: family history of type 2 diabetes and a borderline A1C of 5.6%.

Is she doing the IFD too or just you? Curious to see it that would have any impact on her fasting glucose levels.

She's doing 16-24 hours pretty routinely now and has done 42 a few times.

Turns out she has impaired glucose tolerance! This in delayed response to Thai food + 8 Thin Mints, I believe.



The gap in the data was when I turned off the phone and the receiver to stop the (reactive) urgent low alert that can't be muted.

That sensor went bad after two days. Dexcom’s warranty replacement arrived and is now installed in her arm. Perfect timing since it’ll finish warming up in two hours, prior to another round of Thai food!

so I quit fasting as not having the distraction of work made it really difficult to just hang around my chidlren (who eat every 5 minutes) and not go crazy.

My wife and I are trying a 16:8 every day fasting regimen. I think it's going to help cause I fucking snack like a champ between 8 and 12. So, I cut out the late night booze/snacks and second breakfast/elevensies. I think it will work, and I still get to eat and snack for the 8 hours between 12-8. We'll see.

I've settled in to a 16-18 hour daily routine. Lots of n-3 (salmon and fish oil alike), minimizing n-6 as usual, bulletproof coffee here and there, and almost daily zone 2 exercise time.

This seems to keep me stable or even perhaps trending a bit down per day. I'm still 1.5 lbs or so up from my January baseline.

I'm surprised by that last sentence. Are you saying that after months and months of fasting, all the effort, you have not decreased your body mass? If not what's the point or benefit of this whole exercise?

From July/August through January I dropped ~45 lbs. Since January I've been basically stable. Body has decided this new weight is something it wants to defend.

ok. that's huge. what's next, some weight training? moar pedaling?
I'm trying to get regular zone 2 fake miles in on the Peloton to get a good base for my mitochondria. My bike commute also serves well for this. Do enough of it and one's body gets more efficient at fat oxidation at all effort levels.

See this and the linked-within case study:


Then on top of that my mountain biking/"biking" is just for fun, the zone 3-5 time at the top of the pyramid that should have the zone 2 base much broader at the bottom.

Re zone 3-5 time on the e-bike, see the HR data for the segments here (160 bpm up Infierno!):

My heart is healthy, my stress tests and echo from 5 years ago showed no concerns other than a weird electrical thing that got me to see the doc in the first place. (as the Dr said, its the wiring not plumbing) I have stage 2 hypertension which is well treated.

I often ping off 180bpm when climbing tough sections around here. At near 51 years old, is that a risk in your opinion?

Nah, that wouldn't worry me. Some people run higher than would be expected, and 180 bpm is not, say, 230.

Lowering insulin levels through some fasting (like 16-18 hours, not even the long crazy ones) might help with hypertension, btw. But I won't dwell on that else @Full Trucker will get all up in arms. :D

Whereas nowadays I can just about get to mid-150's when I'm absolutely redlined.

What’s your resting heart rate these days? 40s? Mine is lower 50s to upper 40s spending on the day even at my very modest level of conditioning.

Probably around 50ish, my max was never super high even 10 years ago when I was racing all over the place. It's probably dropped about 10bpm since then, but I don't know if altitude has impacted it too.
