Ok on the serious side - there really is a difference between grass fed butter and non?
The difference between Omega-6 fatty acids and Omega-3 fatty acids.
If they eat the grain, and you eat the fat, you're getting some of the bad stuff from the grain because a bunch of Omega-6 is pretty much a good portion of the problem you get from eating grain in the first place I guess. Omega-3 = Good, Omega-6 = inflammation of your insides and all sorts of problems. Plus glutens and a bunch of other factors obviously.
But it's not as horrible as some paleo people will tell you. Buy very lean meat and substitute your own healthy oils and you're pretty much fine.
From wikipedia -
Modern Western diets typically have ratios of n−6 to n−3 in excess of 10 to 1, some as high as 30 to 1. The optimal ratio is thought to be 4 to 1 or lower.[6][7]
Excess n−6 fats interfere with the health benefits of n−3 fats, in part because they compete for the same rate-limiting enzymes. A high proportion of n−6 to n−3 fat in the diet shifts the physiological state in the tissues toward the pathogenesis of many diseases: prothrombotic, proinflammatory and proconstrictive.[8]
Chronic excessive production of n−6 eicosanoids is associated with heart attacks, thrombotic stroke, arrhythmia, arthritis, osteoporosis, inflammation, mood disorders, obesity, and cancer.[9] Many of the medications used to treat and manage these conditions work by blocking the effects of the potent n−6 fat, arachidonic acid.[
So you wanna control your proportions of omega-3 to omega-6. Lots of Omega-3, as little Omega-6 and you can manage.
That is one thing I can attest to from experience, FWIW. My legs used to be swollen all the friggin' time before the paleo thing. After about a week on paleo the swelling and water retention went away and hasn't come back. That would have been since the end of October last year.
I've been dealing with a bunch of shitty side effects of paleo, but the thing works overall. My BP wasn't bad at all before, at 120/90 (A little high but great for a 440lb dude and not even close to borderline.) It's dropped since paleo.
The main beef I've had is -
1. "Ketosis Flu" (A bunch of symptoms caused by high ketone counts)
2. Lethargy
3. Shitty temper and moodiness.
4. Lots of sleep issues.
The more I study up, the more it seems that I may just be fucked in regards to these symptoms (Until I lose more weight) because it's probably caused by the huge amount of fat being burned. (Again, I started at 440lbs) Burning through 200lbs of fat makes for a shitpile of blood toxins and I may just have to suck it up and be miserable for a while basically.
I'm officially at 401.6 this week (
Ish because one morning I was at 399 but I won't call it officially official until a week goes by where I'm under 400.)
So it's been about 40lbs from the end of October to now. At this rate, if it isn't a curve or whatever, I might be well down into the 200's within the year, and that suits me just fine. My "realistic" goal is 250, but deep down I'd love to get down to 185, which is what I weighed from High School to the age of 24 or so.
