Experience with Ramadan-like IF?
 
Anyone here who's doing IF by eating an early breakfast and a late night dinner with approx. 12 hrs of fasting in between?

Late 2006 I had good luck losing with 3 meals/day on a 10am/4pm/10pm schedule, but I wanted to try IF.
The Fast-till-5 was a disaster right away as I didn't feel hungry, as much as cold.
Unfortunately, I can't prove this with a decrease in body temperature, since I've only started measuring body temp after that trial.

This cold feeling went away when I decided to go for an approximately 12hr fast with breakfast at 10am and dinner at 10pm. When I was still eating 3 meals I would sometimes already spontaneously eat at 10am-8pm-10pm because appetite that would increase at 4pm would disappear spontaneously when I was too occupied to eat.

I'm still not 100% sure whether metabolism will not go down with 2 meals as opposed to 3 meals, as calorie intake also dropped for a bit on the 2 meals/day pattern.

BTW, I'm not doing IF on WO days, and have 5-6 meals on those days.

So:
- who eats breakfast+late night dinner as well?
- have you tracked body temperature (objectively and/or subjectively) and noticed a difference?

During most of this past basketball season (when I was coaching) I was doing this schedule:
MWF: 1 meal early (6:30am), one meal late (7:00)
TuTh: Fasting day, one late meal (7:00)
SaSu: Meal out (noon), one later meal (6:00)


And I am definitely with you on the subjective drop in body temperature when working on a longish (15+ hours) fast. I've been fasting today and haven't had to turn on my A/C at all.

I can't really recall if I was experiencing the drop in BT on the days when I ate twice or not.

Definitely notice the drop in body temp. It's hell in the winter when the gym was unheated and ~28*F. It's pretty nice now that Chico is heating up.

that approach is likely quite good...lots of ways to cook that stuff.

I must add that I've got a history of disordered eating. Disordered as it wasn't a true eating disorder, since I just didn't eat poorly because of wanting to lose fat/weight desperately, no I just didn't care about the food.

Only decades later I've diagnosed part of the reason: becoming both gluten- and dairy intolerant without knowing it. Since my mid-teens I've had food-related joint pain as well as GI discomfort. But most of all , I just am never really hungry until food gets into my mouth (or the scent of it into my nose).

So, yes IF is second nature. Considering however, how fast my body temperature drops upon being stressed, I really don't feel it would be a good idea to go with the prolonged fast periods.
For the record, this was confirmed mid-April when a full blood panel was done, and despite normal TSH & T4 values, my T3 was subrange. I wasn't even dieting very strictly at the moment. But indeed had already embarked this 'eat 2 meals/day 3-4 days/week' experiment.

Perhaps some of you can switch from the Fast-till-5 method to this one and share experiences about how different it feels.

I only eat once a day and have no problem with coldness.
I've only experienced coldness when I've tried low carb diet or fasting for more than 44 hours.

Hmm. I wonder if the coldness is not just a product of fasting but the combination of fasting and low carbohydrate...

Yvana van den Hork 06-28-2007 06:04 AM

Depends on what you consider to be low-carb. And then , fasting = zero carb/protein/fats.

Interestingly, I've noticed when I took fish oil caps on their own during the fast that it warmed me up in a similar extent as protein can heat me up.

Excess carbs pre workout can either make my heart race and my head spin, or just very sleepy and have me forget the simplest things.

Avg carb intake is around 150-200g a day (mostly 35% of total calories) with 50-125g on IF-days and 150- sometimes over 400g on workout days.

After reading up on Michael Eades POV on leptin resistance and how lowcarbing can increase leptin sensitivity I'm going to try upping fats instead of mostly carbs on lifting days.

But I digress. It's a pity I never tracked body temperature during the Fast-til-5 experiment, since I've noticed that feeling hot not always equates to 'being' hot.

I haven't noticed any feeling of coldness, even when on the 24 hour EOD fasting (I'm now doing an 18/6 pattern due to work, I also really missed dinners).

I've also been supplementing fish oil at about 2200mg EPA+DHA total and 12.5 mg iodine, so that may definitely play a part.

I took my body temp several days while on the EOD fasting protocol, never saw it below 97.3, and sometimes it would be 98.4.

Yvana van den Hork 06-28-2007 07:23 AM

What then *is* a normal body temp? I'm taking it in order to find out when I ovulate and observe whether appetite really coincides with higher body temperature. Which indeed, is nearly always true.

Lowest sofar was when I camped out and barely slept: 36,2C (97.2F). But it's probably not as low as it used to be, as I'm nearly always fairly warm.
Hottest is at or slightly over 37,0C (98.65F).

AFAIK, you're hypothyroid with temp below 36C? Even more surprising then that T3 is still subrange despite high body temp. OTOH, I know someone on thyroid meds, whose highest temp is 36,2C, my lower limit.

Garrett Smith 06-28-2007 10:32 AM

"Normal" body temp is an interesting question. Lower can be good or not so good, depending on the cause.

I believe it's much like a low HR...a generally good sign in athletes, not so good in unhealthy sedentary folks.
