Intermittent Fasting

Bump. I am interested in this as well. i am working to cut the last 4% of my body fat. Have thought about doing this.

I use it as do many others. Go to this group http://www.myfitnesspal.com/groups/home/49-intermittent-fasting where we share information.

Thanks for posting this. I'm interested in this as well ever since I found the Primal Blueprint.

I do it every week .. I love it ...

I intermittent fast from 10pm -2pm daily. Unless i'm off with the wife.
I eat 2k on rest days and 2800-3k on heavy lifting days.

Because my primary goal is fat loss with concurrent lean mass gains I only heavy lift 3 days a week.

Hormonally i'm more sensitive to insulin because of the fast.
I dont have to do cardio because i'm already pretty strong in that regard and the fast is already burning fat after about 8am.

I suggest you read the ENTIRE www.leangains.com website and add Martin Berkhan to your twitter and Facebook.

IOf you need solid IF dietary numbers please send me an PM and i'll run your info.

I just started yesterday...16 hour fast, 8 hours to eat. I will not be training fasted though as my schedule will not allow. :drinker:

I don't really agree with this because when you fast you spike your insulin levels and when you finally eat because of the high insulin levels everything you eat gets stored as fat in the body.... not a good idea

I would love to see actual support for this in a double blind scientific study. Yes, your insulin goes up when you eat, that is true for everyone when they eat insulin spike, but due to the fast insulin sensitivity is much higher as well, so saying it "spikes" would be a vast overstatement. A healthily functioning body produces enough insulin to do the job. It is when people are insulin resistant that they produce way too much to get the sugar out of their blood. For that matter, the thought that all that food goes to fat is simply incorrect. Due to the fast, especially if your worked out fasted, your muscle and liver are both majorly depleted in glycogen which means the first place the sugar in your blood stream will go is to your muscles and liver to fill them up with stored glycogen.

Wow, you're ignorance isn't limited to thinking everyone needs 50-60% cho in their diets

Lol

ok some people don't like what I said... lol but good for you!! Here are some reasons why you should not INTERMITTENTFAST

A Supplecity site visitor asked about "intermittent fasting," after having read about its many wonders on various blogs and postings written by people with credentials completely unrelated to diet and fat reduction.

The idea behind this is you starve your body of calories just long enough to tap your fat stores but not long enough to trigger your body's starvation defenses. Looking at it from just this perspective, it would appear to be just the thing for a person who wants a magic bullet for losing fat. It's not.

This practice has several serious shortfalls. For starters, it reduces nutrient absorption, causes insulin swings, and plays hell with your kidneys. If you want to go into a coma or wind up on dialysis, this approach is perfect. Otherwise, stay away. It's Dangerous (notice the capital D there?).

Let's step back a moment and look at the bigger picture. If your goal is to "lose weight," then of course mindlessly reducing calories for a short enough period that you don't go into the low-metabolism, calorie conserving mode makes sense.

But, that's not a sensible goal. A sensible goal is fat reduction. And that is hugely different (no pun intended) from weight loss. And so are the consequences. After all, you can lose weight very quickly by having your limbs amputated. Do you think a runner who wants to go faster should lose weight by such a method? Of course not. And it doesn't make sense for anyone else.

You can lose weight by losing lean tissue, and most weight loss methods result in that. What you really want to do is lose excess fat, because that's how you get rid of a root cause of disease.

Nobody has ever gone to a doctor and heard, "Well, your arteries are clogged because you have too much lean mass." No, the problem is the excess body fat.

That excess fat comes from too many calories. But simply cutting calories doesn't fix the fat problem. There's a bit more to it than that.

Your body needs a certain amount of calories each day to:

Maintain healthy bone and muscle.
Maintain healthy organs.
Maintain adequate brain functioning.
Further, you cannot build new muscle on a restricted calorie diet. This means that, for sustainable leanness and fat loss, this diet works against you by inhibiting muscle growth.

Your body also needs a certain level of fiber flow through the digestive system to reduce cancer risk and generally detoxify your system.

When you go on intermittent fasting, all of this stops.

You stop building new muscle, which means you reduce the amount of fat you burn just by sleeping. You will, in fact, lose muscle. And why on earth would you want to risk your job by showing up with a brain that isn't firing on all cylinders? Do you want to drive a car on our dangerous roads in that condition?

This diet, like all other "silver bullet" diets, ignores fundamental principles and tries to get something for nothing.

If you want to reduce your body fat, you will find out how to safely and effectively do that in our other fat loss articles. Go here to see what they are: Weight loss and fat loss articles.

Some general principles of fat loss are as follows:

Get adequate nutrition. Did you notice that the intermittent fasting method violates this?

Eat six meals a day. Did you notice that the intermittent fasting method violates this, also?

Control your portion size to limit calories to what your body needs to maintain lean tissue, based on your lean tissue composition and activity level.

Avoid or eliminate highly processed foods.
If you follow just those four principles, you will see your body fat level go to well within the "Look at that tight bod!" level. Yes, there's more you can do to fine tune things and get really "cut." And maybe you would like more information on the details of doing so.

But it you just follow these four principles, you will get results. You won't need to experiment with a health-challenging, unsustainable, uncomfortable practice like fasting. Intermittently or otherwise.

what are your qualifications? to be saying that.... obviously you do not know science
