Intermediate fasting feedback - POST HERE!
There are so many conflicting arguments on the Internet at the moment about fasting its hard to say wether it's a good thing to trial or what kind of issues can you come across.
A lot of people say it's a typical "weight loss fad" and others say it's a way of life now.
Who here has or is doing IF?
What were the reasons behind it? Where you just wanting to get from 10% BF to 8%?
Any side effects or good results?
Does anyone think this is just another diet fad?
Would be good to hear everyone's opinion or experiences because IF is relatively new and hasn't got long term studies of the health impacts etc

Sorry about the misspelling in the header of this thread
Do the moderators would want to maybe correct it?
I meant "intermittent" not "intermediate"

i like it but i try not to take it uber serious. i usually go pretty wide like 11am-7pm as my eating hours. my favorite part is that it makes it easy to stay under maintenance when you limit your eating hours a little

First, the anecdotal evidence. I'm a guy in my late thirties, with kids, without a bunch of free time. I'm a former national-class sprinter, so I suppose I've got genetics working for me, but age and lack of sleep were starting to take their toll. More urgently, I had relentless hunger all the time—not a problem back in the day when I was training hard 2-4 hours a day, but a serious issue now that I'm older (with a slower metabolism), have had knee surgeries (so can't run as hard anymore), and just don't have the time. So, long story short, I gained about 35 kilos over a few years. Some of it good weight, most of it not.
I lost the weight by going strictly low-carb for about 6 months. That worked, but I was hungry, irritable, and listless all the time; I thought about jumping off that particular wagon every single day. But I had bought a bunch of expensive clothes in my new, smaller sizes, so that wasn't an option. Lol (but srsly, I need bigger closets, folks).
So, like Milarepa of Tibetan lore, I went on a spiritual quest for (dietary) enlightenment. Tried a whole bunch of solutions, all of which left me either (a) hungry and listless, (b) gaining weight back, or (c) without energy for workouts.
Enter a trip where I was stuck in a delayed flight, and then an airport, for a total of over 24 hours. Without money in the local currency, and unwilling to venture outside (and have to return through int'l security) for sustenance. In other words, involuntary IF.
Well, hell, wouldn't you know, I wasn't hungry. At least not in the urgent, holy-crap, I-would-eat-that-plastic-table-right-about-now sense of "hungry" that had characterized all my previous attempts at dieting. It was like a revelation.
Sure I was somewhat hungry, but in a dull, gently urging way, and not in a proto-diabetic FEED ME NOW, MORTAL kind of way.
I had never felt that way before. Ever since retiring from track & field, I had spent eight years oscillating between "starving" and merely "really hungry", trying to stop eating when I reached the latter. The one time in those whole eight years when I truly felt "full", I had consumed about 6,000 calories in one hour.
And, to top it off, I had energy. This didn't make sense at first to my rational brain; I wasn't yet aware that the 12th to 20th hours of fasting provoke an increased adrenocorticoid response (= "adrenaline rush"). I wasn't passing out on the airport floor; I put together an entire thirty-page prospectus while I waited and waited and waited. A level of focus and energy I'd rarely felt outside of the "manic" stage (I'm bipolar).
So yeah, that's my experience.
I immediately adopted "IF" (though I didn't think of it that way) as a lifestyle thing.
On workout days, wake up, fast for 8-9 hours, eat a small amount of sugary cereal + BCAA, go work out like a beast, come home, f*** the all-too-sexually-voracious wife, then eat a satisfyingly huge meal. And pass out within 1 or 2 hours of that meal (I can't sleep more than 2 hours on an empty stomach).
On non-workout days, wake up, fast for 12-14 hours, eat all my food within 4 hours, and then pass out within 1-2 hours of that meal.
Since adopting that plan (with regular cheating) I have regressed to appx 7% body fat, and a hard-to-believe 13-inch drop from chest to waist (42" --> 29", good thing I can tailor my own clothes). My lipids and fasted blood sugar are better. I get to eat meals where I'm reasonably satisfied at the end, rather than perpetually being forced to eat what feels like 1/2 or 1/3 of a meal every time I eat. I'm not as much of a raving a**hole. The hunger doesn't gnaw at my heart and soul. And I've gained substantial strength from eating so many calories post-workout, despite averaging only about 4.5 to 5.5 hours of sleep a day.
There have literally been no downsides. Well, ok, occasionally it was awkward to go to dinner with friends or colleagues and have water or Diet Pepsi for dinner. But that's only weird if you decide it's weird; if you don't, it isn't.
Confounding variables: (I.e., other things that could be at least part of the actual cause here, besides the fasting thing)
* I plan meals more carefully now.
* I don't eat as much convenience food, because I cook huge amounts of "macro" food and then eat it over a few days as leftovers.
* Most importantly, I don't normally eat until after midnight, which means I eat essentially NO restaurant food anymore. That's probably a big factor, what with all the soy oil and sugar that restaurants put into EVERYTHING. (Also, I have more money with which to buy myself clothes.)
Oh, and my thyroid pills are more effective now, too, because I have a 18- to 20-hour fasting window for them to have full effect, rather than just a couple of hours like most people.
As for the evidence, OP, you are wrong about what you characterize as the paucity of that evidence.
The recent popularity of IF is, of course, a new thing. But IF is hardly some johnny-come-lately idea. Fasting diets of all kinds are as old as the hills.
Because of their connection to various religions, fasting has a much longer and more storied history than, well, any other type of diet plan imaginable. Probably more than ALL other diet plans, combined.
You can find studies on "IF" that go back decades and decades. I can't post links (I guess I need a longer posting history to do that), but one particularly fruitful place to look is studies of Muslims who fast for Ramadan—which, particularly if Ramadan falls during summer months, is almost an exact mirror of the 16/8 IF concept.
Because entire countries of people engage in that sort of "IF" together, there are thousands of such studies. Go look, you'll find 'em.
The only complicating factor is that the Ramadan fast also includes abstention from water, while most IF proponents advise an increase in water consumption during the fast (primarily to prevent constipation later, but also to mitigate the "empty stomach" feeling).
There are also loads and loads of "IF" studies that concern ordinary Americans. Poke around the nih.gov database and you'll find those, too.

Thank you for sharing your experience! Appreciated!
Looks like a powerful thing to do for weight loss and overall health!
I might post some studies in this thread

Lethargy, yeah no. I wrote about the energy thing in that book I wrote up there (lol)... but, also, don't forget, any energy supplement you take will be super amped up when you're fasting.
(Do not, I repeat DO NOT, take Roxylean when you are fasted. Unless you are trying out for the role of a tomato in a school play.)
I get sleepy after meals, especially my big post-workout meals, but I eat all my food in the last 4-6 hours before bedtime anyway. So win-win. In fact, my sleep needs have gone down from 6-7 hrs/day to 4.5-6 hrs/day, because the timing is perfect (I fall into deep sleep within a few minutes, according to this sleep monitor thingy that I have).
Bloating, I can't say, there are way too many other variables involved. Plus, I have a low aldosterone problem, so I couldn't retain water even if I tried (I have to drink almost 2 gallons of water a day, some of it salted, to stay hydrated).
The nice thing here, by the way, is that every liter of ICE-COLD water you drink burns 37 calories (thermal energy, your body has to heat it from 0º to 37ºC, you do the math). So if you drink one gallon (= about four liters) of ice-cold water a day, boom! 148 calories. Two gallons, bang! just shy of 300.
Drink that water during the fast, and guess where those calories will come from.

Similar to Eluruguayo posts: I'm 37, married with a 4 month old baby. Stay busy at work and at home. I miss the days of carefree working out when I didn't have all the responsibility as I have now, but the trade off is well worth it. I've tried various types of cutting techniques: low carb, velocity, simple calorie restriction all with success. I started doing some research into physiology/biochemistry during grad school and adopted a form of IF on my own (before its recent popularity). I also had some personnel experience, somewhat, growing up wrestling through college. I was always on the heavier side and had to start cutting weight at the age of 8 and this carried on through college. My research and cutting experience led me to IF.
After college I ballooned up to 286 lbs. I started to get back into shape only due to being 100% Native American and over half my family having type 2 diabetes. I dropped down to approx 170 lbs in about 8 months (all running). After this I started lifting weights seriously through majority of grad school. I got up to 205 lbs at about 9% until I started to feel sluggish and the powerlifting bug hit me. I dropped weight again. This time using IF about 10 years ago. I dropped down to around 160 lbs to compete at 165 lbs.
After various injuries and coming to the end of my grad school and thinking of my career I gave up serious lifting and looking to just live an healthy lifestyle. Being previously overweight I gain weight very easily. During the last 2 trimesters of my wife's pregnancy I put on about 28 lbs of weight to 198 lbs. After our daughter was born I wanted to get the weight off and I adopted a formal IF schedule and in 5 weeks dropped down to 175 lbs. It came off really easy and the whole time I was RARELY hungry. On weekends I didn't even do IF, only Monday-Friday.
I utilized a combination of heavy multi-joint lifts and complexes (olympic/powerlifting movements) with little rest between sets with a short 20-30 minute session of cardio via the stepmill afterward. I would prefer to run but like Eluruguayo I'm 9 months out from knee surgery and haven't been able to run.
I also have to add, when I did eat (11am to 7pm) I didn't go overboard with carbs. What carbs I did eat were low GI (mostly greens). There was a fine balance between normal homeostasis and hypoglycemia during this time. Orthostatic hypotension was a daily occurrence during the 5 weeks and I had to push myself through intense workouts both fasted (worked out at 5am daily) and carb depleted.
At times it was tough energy wise but NEVER hunger wise. When I want to lose weight IF has been my choice for about 10 years now. It's effective but most importantly I'm not hungry which makes it even easier.
The timing that I chose to eat (11am to 7pm) is good for the family man. I could sit down and have a nice meal with my wife every night and she was never affected by my IF at all so she supported me too. I highly recommend it to anyone only for the non-hunger aspect. As with any cut, IF YOUR NOT HUNGRY IT'S EASY.

I got to the point when I sat down for dinner I would eat a small portion of my meal and I would be full. Sometimes after a few bites. Forced more down just so m wife wouldn't get upset.

It can be used for offseason or pre-contest i have used it getting ready for 2 bodybuilding shows (avatar was this july at collegiate nationals) I also have a bulking progress interview on Martin's site from 2 years ago in March.
Side effects - Kills hunger (i never get hungry cutting or bulking)
Easier on a lifestyle, less packing meals, less thinking about food or eating every X hour, allows to be more flexible with food sources for larger meals. More time spent being social, friends, family activities and not bringing or packing food.
You can label it a fad, remember its a "Lifestyle"
just as stated on www.leangains.com
which martin has addressed about 100 times.
It has good backup and scientific support via science and with personal results as shown in his clients.

I've been doing IF for a week now and have actually gained weight?
I am still starving but definitely eating smaller meals or getting fuller quicker
05-06-2013, 10:08 PM
Keep kcals the same and ride it out. If your in a deficit you will lose
if in a surplus you will gain
Common Sense = Common Sense.

Check out all the damage intermittent fasting has done to the muscles of these people
Fasting just destroys your muscles and puts you into starvation mode where you don't lose any fat:
Fasting is bad for your health. Scientific studies have shown that over and over again, like these:
It wrecks blood sugar:

Tell you the truth my belly has expanded so much since being on IF.
It almost looks like I'm pregnant!! :/
Ive only been doing this for a short while and this "bloating" problem started yesterday and it happened today after my late lunch. It is also quite sore as soon as I started the proper 16 hour fasting 2 days ago
Does this effect slowly go away? Is my stomach just getting used to this way of eating due to me being used to eating 6 meals a day at least?

Pasta, Rice, Bread = Easy Carbs
Eggs/Beef = Easy Protein + Whey
Oil's, peanut butter = Easy Fats
Cereal's, Pretzels, Pancake Mix (protein pancakes)
Life is not about oats, broccoli, and quest bars.
