My 1st week of cutting. Will this IF diet be good for a long term cut? I'm somewhere at 20-25% bodyfat and will most likely be cutting for several months.

Yohimbine will release fatty acids into the system about 30 minutes after you take it. You take a dose of caffeine and then go do some LISS. You can not eat ANYTHING within a few hours of taking it because it only works in the absence of insulin. Even dietary fat and protein will ruin its effects. This only comes into play when you get down to low body fat.
36 hours is WAY too long. You've gone catabolic by that point.
Eat stop eat is overkill and its been proven that shorter fasts are better and more muscle sparing.
It's been proven that there is an ideal window of time to fast. You go longer than that and your body starts to turn on itself. Stick within the window and you get a nice shot of growth hormone.Last edited by redheadlaw7; 06-12-2011 at 06:46 PM.

This is not true. People fast for 40+ days(water only) and don't lose any muscle. If you fast correctly(no food at all), your body will shut down its digestive system and burn fat, cysts, tumors, and any other waste products the body doesn't want for fuel. This is the point of fasting for health. Your body will eat up all of the bad stuff it doesn't want, and only after all that is gone will it start burning muscle. Once it starts burning muscle, you are no longer fasting, but instead are in starvation mode. You know this by suddenly getting a hunger for food that you don't feel when fasting. If you get to starvation mode, you've already been fasting for over 40 days usually, and you'll know right away because you're body is telling you you need to eat and your digestive system re-awakens.
However, fasting for long periods of time should not be done for fat loss. Yes you'll lose about a pound of fat a day, but your metabolism gets extremely slow during a fast, and you always gain all of the weight you lost back afterwords, and if you're not careful, a lot more. Fasting for long periods of time should be done only for health/spiritual/religious reasons.

Intermittent Fasting and Stubborn Body Fat
1:28 PM | Posted by Martin Berkhan
What is stubborn body fat?
Stubborn body fat refers to areas of the body that hold on to fat the longest. Generally speaking, these areas include the lower abs and lower back in men, and the lower body in women. These areas are damn hard to get lean.
How come these areas are stubborn in the first place? To understand this, let's look at how fat is mobilized (the very short version).
After you eat, insulin and fatty acids are elevated. You are in the fed state and there's zero fat burning going on. Your body is relying completely on glucose oxidation during the hours following the meal.
One way of measuring this is via the respiratory quotient (RQ). An RQ of 1.0 denotes pure carbohydrate metabolism ("storage mode"), while 0.7 denotes pure fat metabolism. To put this into perspective, consider that RQ is 0.95-1.0 for about 1.5-2 hours after a meal, 0.82-0.85 after overnight fasting and 0.72-0.8 after 16 hours of fasting.
As the hours go by and the nutrients from the meal are done being absorbed, RQ drops in conjunction with insulin. There's a shift towards fat burning and mobilization of stored fat. This process is mediated by insulin and blood-borne fatty acids; when levels drop, an energy deficit is "sensed" and catecholamines (adrenaline and nordrenaline) increase.
The catecholamines travel through the blood and bind to receptors on fat cells. A receptor can be thought of as a "lock." Hormones and neurotransmitters are keys that fit into that lock and make something happen. In this case catecholamines trigger fat mobilization by activating hormone sensitive lipase (HSL), which then shuttles the fat out of the cell to be burned off.
Now here's the critical difference between regular fat and stubborn fat: regular fat have a lot of beta-2 receptors in proportion to alpha-2 receptors.
In The Stubborn Fat Solution Lyle McDonald used the analogy of b2-receptors being "accelerators" for fat loss and a2-receptors acting as "breaks" for fat loss. That's the easiest way to think of them without getting too deep into the physiology.
The ratio between b2-receptors and a2-receptors determines how easy it is to facilitate fat loss from one region of the body. "Easy" fat has a high ratio of b2-receptors to a2-receptors, while stubborn fat has a high ratio of a2-receptors to b2-receptors.
One notorious example that Lyle brings up in his book is that women have up to nine times (!) as many a2-receptors as b2-receptors in their hip and thigh fat. Though I can't recall if similar numbers are available for lower ab and lower back fat for men, you can be sure that the a2-receptors outnumber the b2-receptors in these areas as well.
Intermittent fasting and stubborn fat loss
How can intermittent fasting then selectively target stubborn body fat more effectively than other diets? Well, to target stubborn body fat we need to activate b2-receptors while deactivating a2-receptors. Intermittent fasting achieves this by the following mechanisms.
1. Fasting increases catecholamine levels.
2. Fasting increases abdominal subcutaneous blood flow, which means that catecholamines will have an easier time reaching those hard-to-get areas.
3. The low insulin level reached during the fast inhibits a2-receptors. A greater time spent in the low insulin state equals a greater time spent in a state where fat can be mobilized from stubborn areas. Now you're probably thinking "why not just go on a low carb diet" to keep insulin low, but keep in mind that triglycerides inhibit HSL in a similar manner as insulin.
4. My research has indicated that the ideal state of fat burning is reached after 12-18 hours of fasting. Coupled with high levels of catecholamines, increased blood flow to stubborn regions, and low insulin for a2-receptor inhibition, this time interval is the "golden age" of stubborn fat mobilization.
Let me just explain real quick what I mean by the ideal state of fat burning. Studies have examined free fatty acid (FFA) oxidation from anywhere between the overnight fasted state to three days of fasting. While FFA oxidation increases the longer time you spend in the fasted state, the contribution of fatty acids to whole body fat oxidation changes.
In short-term fasting there's a significant increase in subcutaneous FFA oxidation. That's just a fancy way of saying that you're mainly burning body fat and nothing else. For up to 14-20 hours* after a 600-calorie meal in normal-weight subjects, fat is only mobilized from body fat stores in resting individuals.
* 14-20 hours in a completely sedentary state should easily equal 12-18 hours in real life.
Past this time point, fat burning increases further. That goes without saying. But it's not necessarily the type of fat you're after that you'll be burning. Somewhere in between the 10- and 30-hour time point, the oxidation of intramuscular fat increases greatly, but no increase is seen in subcutaneous fat. Subcutaneous fat simply can't keep up with demand, so you're playing a game of diminishing returns if you push the fast too long. Coupled with the escalating rate of de novo gluconeogenesis, and subsequent risk of muscle catabolism, fasting for too long may not be very conducive for a lean individual seeking optimal lean mass retention while targeting stubborn body fat.

i started this yesterday.. dunno if it's 'Intermittent fasting' but i basically have 500 calories (shakes and some nuts) (96 grams of protein) by 6pm... hit the gym... come back home.. have a shake...and have 1000 calories in one meal after a few hours.. i dont get hungry much during the day anyways and this seems like it would work for me as im more of a night eater anyways.
my strength seems fine so far...

I might try it tomorrow. Ormaybe i'll wait anothe rweek since i start ec stack again in 1 more week, so if i fast along with ec it might go a lot farther as far as fat burning goes. I might try and bulk sort of this week uz i scrweed up by not eating enough and went from 185 to about 180 in a matter of maybe 7 days, now my bench and squats have gone down dramatically i wanna bring them back up a little first. lol

It can be really hard to go cold turkey from 5-6 meals per day to IF'ing. I tried it that way at first and wanted to shoot myself. The next time, I gradually cut back on meals. From 5 meals/day to 3, then down to a small eating window in the evenings. When I tried to do it cold turkey I found I was always bingeing in my eating window, but not when I cut back more gradually.
