is any one doing the fast diet?

I did alternate day intermittent fasting for weight loss, which is a stricter version of the 5:2 plan. I tried doing 5:2 for maintenance, but kept losing weight so I had to stop Now I'm experimenting with 8/16 IF. There's a 5:2 group on mfp, as well as a general IF group-check them out!

Found a link to the video!

I regularly do a 24h fast and then eat 500 cals. Works well for me if i've over indulged or just want to give my body a bit of a break. Mood wise it kinda makes me trip out a bit.

Do you do that just the days after you have over indulged. I think Id be so moody!

Not always. Does work wonders though. Kind of like hitting reset. Otherwise i normally do it on a day that im not working it out. It just makes me feel good. I don't really get moody

I'm doing it. Too soon to know if it's working though.

I've been doing the "fast diet" (more commonly known as "5:2" on here) for 16 weeks (fast #33 today).

It works a treat for weight loss (39lbs so far), and supposedly has other health benefits too (though many would argue they are as yet unproven).

I personally haven't noticed any real physical problems (tiredness, headaches etc.) on fasting days, but some others do report them.

At first, I found I was going to bed early on fasting days, but that was in an attempt to get the day over with and remove the temptation to eat more! That soon passed though, and now I barely notice the fast days. If I feel hungry, I drink a pint of water and give it half an hour - the pangs go away quickly enough,

If at the end of this math equation there is a deficit, then yes, it will work.

thanks for the link. I may try it.

Out of interest - what do you class as a fast day? From morning to bedtime?

I stop eating after dinner the day before a fast day, about 6pm, then I don't eat till after 6pm the following day.

So far as I know there is no formula for it, but would be good to get other peoples take on it...

The original concept is a calendar day, so have dinner on Day 0, then have 500-600 cals on the Fast Day (Day 1) then a normal breakfast on Day 2. Many people eat their calorie allowance as a single meal - dinner on Day 1.

How many calories do you take in on the days you aren't fasting then? Maintenance?

Tread cautiously. Fasting has been around for thousands of years, and both the pros and come sides of the fasting arguments have good truths as well as loads of BS.
First off, no one should fast for longer than 48hrs at a time. Starvation mode is not a myth, it just takes longer to get to that point than people think.
If you have great self-control, then awesome...but if not, it's quite common for people to have bad binges after fasting, and a good chunk of people gain back all the weight that they lost from fasting...but like I said, if you possess good self-control you shouldn't have to worry.

It's possible that you'll experience nausea, moodiness, dizziness, constipation, etc etc. All of that stuff depends on the individual.

Prolonged fasting can cause your metabolism to slow because your body is conserving energy, and once you hit that point of the slowing metabolism and muscle disintegration, you could be heading to a world of hurt-but you'd have to eat nothing for awhile.

Of course it's always smart to consult with your doc before trying something like this. You may not like what you hear, because most doctors discourage fasting. It's dangerous that you may love the weight-loss a bit too much and end up full blown anorexic. At that point, of going too long without eating, you can suffer severe electrolyte imbalances, kidney failure, gallstones, liver failure, coma, and yes, death. I, myself, am a recovering Anorexic. I was institutionalized at 16 for a period of time and suffered a relapse when I was 18. It took time for my metabolism to recover, I lost virtually all of my muscle, grew a thin layer of hair all over my body, could not grow nails or my hair out due to the brittleness, and to this day I get kidney and liver screenings regularly and I might have 2 to 3 periods a year if I'm lucky.
I was real perfect and beautiful alright
Good luck! Just be careful with it, and make sure you're healthy. Some people should never ever fast; anemics, AIDS patients, cancer patients, women at risk of pregnancy, diabetics, people with kidney conditions or liver conditions (including heavy drinkers), and people who take certain prescription drugs.

Keep in mind, the people who die from prolonged fasting, or who just have a hard time and struggle during their fast, are those who are in a weakened state when they begin their fast.

Be sure you're nice and strong and healthy and not on an Rx that could make it dangerous, and go kick a**, girl

I hate talking about this with people LMAO. I don't mean on here i mean in real life. I never even knew this fasting thing was a "fad" until I saw something on the national news here.

I personally do a 16/8 intermittent fast - mostly got my info from LeanGains.com

I hate talking about it because the actual fasting isn't that important to me in terms of weight loss. For me it is all about calories in and calories out - the fasting is just a "schedule" that helps me personally.

The 16/8 fast is no magic bullet - I am not even sure if people my size are encouraged to use it - but the schedule fits my lifestyle perfectly and it is a mental thing...or a habit. I had bad problems with "grazing". Ya know mindlessly grabbing a bite of cheese here and then, or just grabbing something quick out of the fridge like olives etc... With the 16/8 split, yeah I still somewhat graze during my eating hours, but damage is limited because on the fasting hours I eat nothing. It is like knowing that has become ingrained in my mind. So I find it much easier not to graze...weird I can't tell you psychologically why or how it works for me - but it does.

I also enjoy the fact it allows me to eat bigger meals. (as opposed to the 6 small meals a day methodology)

I mostly follow this protocol (Protocol 3 from Lean Gains)

12-1 PM or around lunch/noon: Pre-workout meal. Approximately 20-25% of daily total calorie intake.
3-4 PM: Training should happen a few hours after the pre-workout meal.
4-5 PM: Post-workout meal (largest meal).
8-9 PM: Last meal before the fast.

So far so good. I don't think fasting is a magic easy button or anything - it still requires willpower and calore deficit, but for osme people it is a great way to schedule those calories.

The intermittent fasting protocol is actually a really healthy thing to do not only for weight loss. There are also some other benefits that seem t ooccur when fasting.These include certain improvement in the blood pricture and improvements in different biomarksers, so it's quite reccomendable t odo it. (and I'm talking science backed improvements; http://healthyeatingharbor.com/healthy-living-articles/chapter-i/should-i-eat-intermittent-fasting-meal-frequency-evidence-based you can check it up here)

However! Women do respond differently to intermittent fasting so I would be a bit cautious about that for the females who would like to get into intermittent fasting.
