have you ever wondered how a cat can never do anything, lie in the sun all day and night, go for a brief walk, sit by the cave entrance of a mouse, catch a mouse in one jump and go back to sleeping again, and yet never get sick, never get fat, even if you feed milk to it, and with such zero exercise still jump on a fence that is two or three lengths of its body? God gifted, isn't it?
No. I can do the same. My life style is: i lie on a couch and in the sun reading books, learning something, listening to music, sleeping all day every day except when I eat and when I exercise. 
I eat literally this with paranoid avoidance of everything not listed here: beef with much tallow, lamb, wild fish, eggs, poultry, occasionally pork, all of that mostly raw, barely fried on tallow both sides; black pepper, salt; japanese sencha tea prepared in traditional jap ceremony (but never matcha), black coffee, water, everything unsweetened, smoke cigars (not cigarettes nor cigarillos), cold pressed coconut oil, occasionally a little honey or clean white sugar, occasionally a little clean (see through) fresh juice, occasionally various organs of the same animals,occasionally hard aged cheese that has 0 carbs in it. All of it ecological. I am concious that all the things that are made of plants that I mentioned are drugs (glucose or alcaloids). So I drug myself because I can, but always concious to measure how I feel and not to overdue it. I especially avoid plant oils (except coconut oil because it is different) because they are straight poison breaking basically everything in your body short and long term, and also avoid fiber because that is useless stuff also lightly poisoning your gut and your muscle (muscle not directly but through excessive sugars and other stuff that bacteria digesting fiber releases into you). 
I exercise exactly this no more and no less: 5km jogging 3 times a week, 10 pullups 3 times a week, 25 pushups 3 times a week, 20 situps 2 times a week. 2 or 3 times a year for two to three weeks in a row I skip even that. After a break I get back to doing my regular with no warm ups and I never have any muscle pains nor numbness.
I have a six pack, I am slim but ripped as terminator, I weigh 80kg, I am 45 years old. I can ski, surf, scate, swim, sail, basically do anything you can think of. I never have so much as a runny nose nor cough even in the cold climates. No diseases whatsoever. All my ancestors were white, and I would be white too if I did not get so much sun. My avatar with a cigarette is from my previous life. I do not look like that anymore.
