No, he doesn't mean eat fat while fasting. Eat healthy fatty foods when not fasting, but especially your last meal before commencing any fast should be as fatty as possible. Avocado, unsweetened peanut butter, haloumi cheese & egg fried in a healthy oil (such as rice bran, grape seed, etc), most nuts (especially pecan, macadamia and Brazil), olive oil-based salad dressing etc., are all good sources of healthy fats. The idea is that they put you in 'fat burniing mode', so you burn fat for fuel instead of carbs. Not only does that extend the benefits of your fast, but it will help you control your weight much better, and is also the basis of a much healthier diet longterm. Keeping carbs to an absolute minimum should be your longterm goal.

As for water fasting being easier than a dry fast, I find the opposite to be true. In my own experience, drinking water actually increases appetite, hunger pangs, feeling 'empty', etc. I find it much easier to control these signals when I'm not drinking water. Try it for yourself, if only to see how your body responds. You may be pleasantly surprised, and there's no need to go to any extremes. Try it for a day initially, then water fast. Then 2 dry days, etc, until you reach 5 dry days. 

But don't stick rigidly to that regimen if you experience genuine thirst. Thirst should always be quenched, else you risk damaging your kidneys. Learn to 'listen' to your body. It will always tell you what it needs. Just don't give it any food while your fasting, otherwise it isn't really a fast. It would be more accurate to call it a diet, even if it's an extreme diet.  

1. Firstly, he is not referring to normal hunger pangs. Everybody has those after more than around 8 hrs since last meal. Those are precisely the signals that cause fear and dread in novice fasters, and are likely the most common reason for unplanned breaks. I won't call them failed fasts on principle, coz any break from your usual feeding routine should be considered a victory. One way of looking at it is as a 'dry run' or mental preparation for the real thing.

Secondly, as you correctly point out, the 72+ hr 'hump' is the bane of every seasoned faster. Once you get past that initial hurdle, the rest is relatively easy. That's not to say there are no more challenges ahead, coz believe me - there are. They can vary from seemingly unrelated symptoms such as severe itching and nausea to a thumping heart beat and dizziness. Almost all such symptoms are the body's reaction to the detox that is now underway, and hopefully one of the main reasons you undertook the fast in the first place.

Finally, and long after you are likely to break your own fast, true hunger returns again. Unless you fast for a minimum of 30 days (and for most ppl it's actually around 40 days), it is highly unlikely you will ever experience this hunger. For all practical purposes, I would not worry too much about it. It is not necessary to experience this before breaking. The fasting doc is an experienced & highly qualified practitioner, & I'm pretty sure he would say that waiting until hunger returns before breaking should only be done under supervision.

2. So basically, you're trying to eliminate all traces of visceral fat. That's no bad thing. You haven't given me your height, so it's impossible to tell what your BMI is. Regardless, my preferred MO approximates to the following. Fast until you drop roughly 10-15lb below the average recommended weight for your height. That should virtually guarantee the elimination of all excess fat and 'redundant' body tissue.

After following a suitable breaking protocol, start a new feeding regimen that takes in both cardio and resistence exercises, and a good quality protein powder for building up muscle mass. You can add it to shakes, smoothies, oats, etc. But be very careful with latter if you eat it. You'll need to find a reliable organic source, coz Quaker use GMO cereals, and have been found to contain dangerous levels of glyphosate, aka roundup:

Personally, I wouldn't touch Quaker Oats with a bargepole. You wanna know what roundup can do? Just watch 14:00 - 17:15 of this:

Happy fasting mate, and don't let Monsanto steal your health.
