I wasn't suggesting eating hippos or elephants,,, but most likely those are the animals along with water buffaloes and other herd animals that roamed the plains of Africa that primitive hunter gathers feasted on.  Yes the meat of bison is lower in fat, but if you read up on the plains indians and early settlers/bison hunters they chose the older ones, especially at end of summer where they had hundreds of pounds of fat stored on their body for the winter months ahead.   Most of the mammals and animals in the North pole are also fully fat.    This has been a debate for some time with Cordain and others.  You can try to prove a point if you look narrow enough.  However there have been large regions of the world with animals with large fat stores, and in numbers where protein excesses were most likely wasted in favor of foods people wanted.     
     There are only a 'few' people researching and teaching low protein, high fat diets,, Ron Rosedale being one of them.  Eating a high protein diet doesn't show up as detrimental over the short term, just as eating a high fruit diet doesn't.  One thinks everything is fine because it's so hard to note one's health decline since we live in our bodies day to day, and can hardly notice small declines.  That's exactly what happens to heavy  fruit eaters,,, they feel wonderful when first starting out;  all those organic distilled waters in the fruits, so cleansing, so energizing with all the sugars fueling their bodies, and then they have to eat more and more sugar for the same effect, and then the leptin and insulin resistance builds and then a slow downward spiral begins,, with most thinking that they are in some sort of detox, where they need to fast again or they need to move to the tropics because they are now so sensitive to pollutants,  that they are so spiritually sensitive that they need to protect themselves from the rest of us. 
   I'm suggesting  something similar happens when we eat too much protein.  It turns into blood sugar, we feel good, but at the expense of longevity.    Rosedale says something almost unique,,,  we weren't designed to live forever, just long enough to pass along our genes and teach our offspring how to survive.   I believe that's where science can offer something beyond that of simply following what and how much our ancestors ate,, if that's even possible to know.

Enticing is a-ok in moderation.  For example, during rambutan season I can perhaps finish 1/4 kilo of rambutan at the most.  But my wife would eat 1 kilo by herself... that doesn't seem right.  She and the kids would eat rambutan every day.

Yes it matters if the fat is heated.
Raw fat is truly the best.
You need to buy RAW virgin coconut oil. (not heated)

My experience and other's experience is you lose the addiction to sugary sweet stuff.  My father in law didn't want to do it as he said that would deprive him of a pleasure to eat chocolates.

Hey, I can eat chocolate at times for socializing, but it is not some "special" food you crave and gorge on.

Are you eating organic or non-organic. I was told many years ago to avoid all non-organic fresh fruit as they are sprayed with I think ethyline gas or something to ripen them, which causes them to produce the same toxin found in latex but at much higher levels. Quit eating non-organic tomatoes, bananas, strawberries and others and my acne cleared up! It was also believed to have been a possible cause of a tumor that I had for 9 years.

This can be true.  Certainly raw foods tend to cause sudden, extreme changes, versus cooked/processed foods, which cause more gradual/slow changes.

Me too. What's the issue?

What bananas can you get in your area? Anything other than Cavendish is possibly better. Your results will be the determining factor in whether a different variety is good for you. Best place to look is in ethnic markets, if you have them in your area.

If you are consuming factory bananas, such as cavendish, you must know they are full of chemicals and herbicides and pesticides and everything they can pump into them.

You may be suffering from factory banana poisoning.

Wild-caught seafoods, especially cod fish, have lots of iodine.  Seaweeds have a lot of iodine as well.
