How do you guys feel about fasting?

This really annoys me - people spouting on about how it is not normal.
NORMAL these days is eating food cooked in fats designed for candles. Huge amounts of food is served retrieved by mechinical means off the parts of animals that were never touched before and turned into meat sludge before being reformed. Normal is filling our food full of preservatives and additives . Normal is removing the natural flavouring and making a chemical version.
Do you think 100 years ago, let alone 500, 1000, 2000 we had this access to foods? Of course not - natural was a meal or two a day after it had been caught, natural was getting a small amount of grain each day or fruit from the bush etc.
Evolution to the new availability of foods would take hundreds of thousands, nay millions of years. Yet we dare to call eating for the last 8 hours of the day instead of 16 un-natural?

People go on about bro science. Heck, surely its better than no science? (aka gut instinct).
Anyhoo - this isn't even that - it is measurable and can be seen in the photo's above.0 -
If you're doing it to detox and flush your system, I think it's a great idea! If you're doing it for religious regions, awesome! But if you're doing it as some short term fix to lose weight quickly, hmmm... you might be playing with metabolism fire. Any kind of starvation is not something one should make a habit out of.

Bump. I do IF sometimes, usually it's the 16/8 approach. I've done a 24 hour one once but I didn't enjoy it. I too have read leangains and articles from marks apple and there has been research stating that it is in fact healthy to fast. You just have to educate yourself and be safe.0

I've started doing Intermittent fasting these last couple of weeks. It only works if I keep myself busy, so I make sure I don't fast on my days off from work. And to be honest, because it's from 6pm one day to 6pm the next, I barely notice it.
If I do have to do a lot of running around and my blood sugar does go a bit hypo, then I tend to snack on a few nuts such as almonds or macadamia nuts and that does the trick brilliantly. I honestly don't feel hunger until it comes to the evening and by then I am happy with a small meal.
Funnily enough when I have dieted all I could focus on was what I was going to eat next. With IF the focus from food is taken away from me. I don't feel guilty if I do eat something - I simply fast the next day. It is working for me so far. xxx0 -
I think the most important thing to take away from this collision of intelligent dieting structure and broscience is this:
1. No one things starving yourself is a good idea.
2. Intermittent Fasting (which is NOT what the OP was considering doing) is NOT starving yourself.
3. Lots of people pop off at the mouth with unsubstantiated dietary myths that have no clinical backing.
4. There are a substantial number of MFP members who have made IF a part of their lifestyle and have had positive results.0 -
Not a great idea. It will slow your metabolism. If you do not eat anything your body will start using your muscles for energy, and leave the fat for reserves. I know this because I have done a lot of reading not the subject.
I know we are not supposed to promote other products so the best thing I can say is try to make sure you get all your nutrients. When I am pressed for time I rely on hard boiled egg whites as a snack.
I don't know if this helps, but I do know that it is not healthy to not eat anything.0 -
Over the short term fasting isnt likely to cause any problems. The real issue with fasting (if done too much) could be the formation of gall stones and heart problems that can result in death. Though fasting may work in the short term you have to ask yourself whether its really a lasting solution. Weight loss is as much about retraining yourself to eat and live right again. Fasting will likely lead to yo-yo style dieting as you will never learn to have a good relationship with food and dieting. It will also likely lead to mood swings and may mess with your general sense of well being. If you are eating 1200 calories a day and not losing weight... I'd first buy a food scale and measure everything you eat. Are you SURE you are only eating 1200 a day? also.. 15 mins of exercise isn't much. If you are logging anything more than 150 calories (to eat back) i'd be very skeptical.0
-
definitely the worst idea ever..... when you fast your insulin levels spike, when you finally eat again everything you eat will get stored as fat... also in those fasting days how are you going to get protein for muscles? carbohydrates for energy? nutrients and vitamins for your immune system? and even 1200 calories is not enough to supply the body with the fuel it needs...... just eat a lot of small well balanced meals every 3 hours and you will speed your metabolism, starving yourself is not the answer
I agree I personally think its a bad idea - mainly because I think it will be incredibly difficult not to binge out over the week and also as your blood sugar levels drop, your body will begin to break down protein (and of course fat) converting them into glucose via various metabolic pathways. Unfortunately, as your not eating protein youll break down muscle tissue. Therefore a lot of the weight loss can be accounted for by lost "water weight" (i.e. water lost that is normally stored with glycogen in muscle) and a reduction in lean body mass which will also lead to a reduction in BMR. However, insulin will not spike... if you fast insulin drops. There are pros and cons to fasting - you will probably lose fat faster but you may also lose some lean body mass, and probably experience a lot of random emotions so just be careful with whatever you decide to do
As for detoxing... What exactly is detoxing? :S Is it supposed to refer to toxins that build up in the body? If so which toxins? The only toxins im aware of that "build up" are free radicals and reactive oxygen/nitrogen species. If your "detoxing" these then well its probably worth knowing that theyre actually useful in upregulating mRNA synthesis for muscle growth as a response to exercise (although they can also be damaging). Other toxins I can think of is urea? But thats not really an issue... umm anyone know what the "Toxins" actually are? - Genuine question0 -
"From what I have read/seen so far on reduced calorie intake and IF research (*studies listed at end), the conclusion is that using short-term fasting may be effective when it comes to:
Reducing blood glucose and insulin levels (improving the state of the overall glucose metabolism)
Increasing fatty acid oxidation with increased FFAs (through increasing lipolysis hormones GH, glucagon and adrenaline)
Sparing and preserving muscle tissue (lean mass)
Increasing various health factors (lower inflammation, lower blood pressure, reduced oxidative stress, increased protection against neuro-degenerative diseases, and more)
Keeping the metabolism strong/healthy"

I could believe most of that except "sparing and preserving muscle tissue". At best I could accept that it doesnt have a detrimental affect on lean body mass, but I cant see how it could actively spare muscle in any way better than normal dieting - Not sure if thats what that article meant but just dont seem right :S0 -

Binging is usually caused by a massive ingestion of carbohydrates. Even if one does have a reload day and doesn't binge on crap, the worst this will do is increase leptin levels and thus triiodothyronine levels in the body keeping the metabolism ticking over.
You're body will not begin converting proteins via glycogenesis at all. There is no metabolic pathways beyond this. What pathways are you suggesting? Heck, why would it be doing that when using IF? Absolute baloney. Have you got any proof of this suggestion? Furthermore, IF is not about low carbs either so I'm not really sure what you are on about.
Fasting 16 hours is fairly normal. S lot of people sleep 10 hours a day - are they wasting away too? As I'm sure you are aware, protein spikes insulin levels, of course not as greatly as carbs, esp simple ones but it still does with protein ingestion.0 -
I have been looking up a few sites that say fasting is good for you AND your weight loss.
I'm very curious to know if this is true or just a scam.
I was planning on doing my MFP 1200 calorie goal, 5 days a week, and fasting 2 days a week (Tuesday and Thursday.)
Is this a bad idea?
I have a very busy schedule and usually don't have time to work out until after 8pm, which is bad?
(that's what I've been told anyways.)
So I usually do a 15 minute work out on my lunch breaks, but it doesn't seem to be getting me anywhere.
Will fasting help me get to my goal a little quicker?
Religious/Spiritual reasons - I would do it0 -

Wasnt refering to glycogenesis - Which is making glycogen from glucose :S. I was refereing to transamination and deamination of amino acids (for example: glutamine > Glutamate > alpha glutamate) that can enter the TCA cycle just like carbohydrates (Glucose > Pyruvate > Oxaloacetate) or fats (Fatty acids > Acetyl CoA). Then of course once youve got your Oxaloacetate from TCA cycle you can form glucose via gluconeogensis. And of course theres the direct Glucose-Alanine pathway :S - There are a lot more pathways than just glyogenesis so not quite sure what you meant either :S.
I was also refering to the original poster who was suggesting that they did two full days of fasting per week (i.e. a 24 hour period) - Not to the intermittent fasting of 16 hours which, including sleep, I doubt would have any major negative affects - although I dont necessarily see the advantages. (If the original poster was suggesting they were going to do IF then I apologise as I was mistaken in believing they meant 24 hours)0 -
Ok haven't read a thing here and don't won't too.
Fasting has been around for years, most that fasted 20 years ago aren't alive today. Fact!
Purging your body of chemicals is something that I would actually advise you to have advise on. There are so many chemicals now and so much of our food is treated with it to make it's life longer.. Not Yours ... Its'\\\
Fasting is eliminating stuff from your body so, heh,,, start slow take all dairy out, see how that works for you.0 -

Sorry my bad - typing quickly - gluconeogenesis is what I mean :laugh:
I think tbh we are then talking cross purposes - I believed as the thread had turned to IF and thought you were discussing that. IMO I'd the odd 24 fast is fine, regular fasting for 24 hours has no real sense behind it however and would agree with a lot of what you say.0 -
I fast once a month with my church. It is good for your body and helps you have some self control. When I am done with it, I feel more in control of myself and more in tune with my soul. It has never stalled my weight loss. In fact, it has always felt very cleansing and a nice way to start the month. Just be sure after your fast that you rehydrate well and eat good for you foods, not binge on junk. If you are looking for a spiritual boost and why fasting can help you feel closer to God, there are some really great scriptures in Isaiah. Don't know if this has helped at all, good luck!!0

The Major advantage to IF is getting to eat 2 -3 big meals, carbs and all ( yes even after 7pm bro) and not going over daily macros, none of this tiny 6 meals a day portions BS. its easier to hit cal deficit thus weight loss. I find snacking and lots of little meals during a 15hr eating window is easier to go over your cal intake.0 -

Every statement here is a myth.
Insulin is controlled when you fast, insulin spikes when you eat starches and carbs and after fasting everything you is not stored as fat............
And eating small meals every couple of hours does not speed up the metabolism and Intermittent Fasting is not starvation.0 -

what a joker... and even if 100% of the calories were stored as fat. If you are in a deficit you will have oxidized more fat from storage then you are putting back into storage at the end of the day. Wish people would think critically about the **** they hear.0 -
no one needs to fast for 2 days straight 16-24hrs is enough. Then crush food like a boss and lift some heavy shiz. repeat.0

How long do you want to fast?0 -
CRAZY. Definitely not a good idea.
Top 10 worst posts of all time. I almost reported it to the admins0 -
it depends on how you do it. there is the IF protocols... some people do 16 hour fasts which really isn't that bad if you're sleeping part of the time and it could help with fat loss... 16 hours could mean eating at 4pm and then not again until 8am the next day... really not that bad for you. i know a few have gotten good results if they want to lose fat. now i think if your'e fasting for days and days that is a way different story! not something i would do or recommend.0

i agree. the main reason i am giving IF a try is because i snack way too much and go way over. 2-3 meals is perfect. i have to get comfortable with being hungry at times. that is my problem, i cant' recognize hunger. so i think if you did IF that worked for you it woudl be fine. for me that just means don't eat from 4pm-8am... 16 hours. easy.0 -
As far as fasting goes, I have tried it and any results I ever had were temporary. But that's not to say it doesn't work for some people. But Dr. Oz did a show on it once, and tested it out and said that any weight loss that resulted from it was only temporary.
Have you thought about trying alternating calories? Like a version of the up day down day diet or other similar diets. These seem to fire up the metabolism and I've had pretty good results trying them myself. Just a suggestion.0 -

I have a big bottle of water next to me during fasting period and sip on that getting my daily water intake but also to keep you occupied. I usually try get 8 cups in before 12pm keeps me distracted. i feel great for the rest of the day. good luck0 -
Fasting works for me. I eat just one meal a day, no snacks, only low-cal or no-cal drinks.
My healthcare people don't approve but I see several real benefits:
Weight loss (duh!)
More energy, mental & physical
Good control of blood glucose - have stopped taking diabetes meds
Have followed this pattern for a couple months now, no ill effects at all. Appetite is not a problem, after initial adjustment.
Fasting for more than 23.5 hours I do occasionally but always have plenty liquids and some light exercise0
