On the original question "Why am I always so tired after eating fruit?"

I only get tired after eating fruit when I eat high fat raw. So the solution to thrive is on days when eating fruit eat only raw lean meat (not together of course). And on days when you want to eat high fat raw don't eat fruit but be zero carb. It's really that simple. But this might not work for people with damaged bodies who are managing symptoms.

FRUIT+RAW LEAN MEAT = BLISS
and
HIGH FAT RAW+RAW LEAN MEAT (zero carb) = BLISS
but
FRUIT+HIGH FAT RAW = TROUBLE

The second reason is that if I eat a single apple I feel an intense craving to have another and another.  I could eat 20 apples in one sitting.  My hunger cravings are much more intense when eating fruit

This is a clue, don't ignore it. Try 3 days 100% fruitarian diet and get around 1800-2200 cal from fruit. Best is 3 monomeals where you eat one type of fruit for each meal. On the fourth day eat only 2 monomeals of fruit and one meal of raw lean meat. Then go back to 3 days 100% fruitarian and again on the fourth day replace one meal with a raw meat meal. Do this for one month and see if you feel much better. This is a protocol for healing and not recommended for longer periods. After you are healed you should be able to eat raw meat and raw fat with no problems but high raw fat is not the answer when your body is broken. Fruit is as it is the lightest for the body to digest so an enormous amount of energy is freed up for healing. You will get some raw fat from lean meat meals and this is enough for healthy body chemistry and hormonal balance while on this healing protocol.

FRUIT=fuel for the body
RAW PROTEIN=cellular regeneration and repair
RAW FAT=optimal body chemistry and hormonal balance

After you are healed a protocol I recommend is 2 raw meat meals and one fruit monomeal (500-700 cal) per day. Then each third or fourth day one high raw fat meal instead of raw lean meat meal. This gives the best energy, vitality, mental clarity, optimal hormonal levels, lean muscular body, incredible strength and stamina. High raw fat every day I have found to slow me down drastically and I don't want that. I want power and explosive vitality.

Ok, I just did an experiment and here's what I've found out:

cold meat = sleeping meat but still alive
warmed up meat= alive and vibrant
cooked meat = dead matter

Warming it up like I did kick starts it back to life. It becomes alive again. I took 2 pieces of raw meat, one cold and one warmed up for one second on both sides.  I ate both of them. I closed my eyes to focus completely on the experience of how it feels in my mouth. The cold raw meat I don't want to chew. I just want to swallow it as quickly as possible. But it's still alive. Then I ate the warmed up 'kick started' meat. Something energetic is absorbed, I can feel it when it makes contact with the inside of my mouth. I want to chew as long as possible and absorb all of it whatever it is. It feels more alive and vibrant.

From experience I know that it doesn't work with ground beef. Ground beef does not feel alive anymore. But it's still less dead than cooked meat. I can't wait to try just killed meat, I can only imagine what it must feel like.
