Wow! I don't know about you, but even a little bit of fish oil makes me get fat... fish oil obsession is BS in my opinion unless you're a serious calorie burner the likes of Michael Phelps. Otherwise, you can just as easily have the benefits of fish oil by removing junk fats and oils from your diet, even with alpha cyclodextrin weight loss products. I strongly suggest that everyone who is overweight, even a little, stop taking fish oil. I've tried all of it, from the lowest grade to the top, just a gram or two a day makes me gain fat weight and I lose it as soon as I come off of it. I get absolutely no cognitive benefits from it... The cost of alpha cyclodextrin weight loss products cost about the same as the fish oil and you learn which fats/foods to take it with for optimal health. For me, I see significantly lower inflammation when I use it to remove canola oil from my diet.
Now mind you, as with a around 20% of the population, I'm obesity resistant (though not part of the 12% that is virtually immune to it) and it takes me 5x the energy to make storage fats. So for me to gain weight just from taking fish oil is quite odd. I feel like people sell the idea of taking fish oil b/c it's low calorie and might make your skin look good. But I think what's happening in reality is that all fats are weighed as being the same in terms of calories despite being very different and researchers either don't have enough information, or they are ignoring this fact in favor of making money.
The sheer number of old people taking fish oil and the sheer number of old people holding onto their weight is astounding. It used to be that old people, at least some of them, would lose weight when they got old and grey, now fewer are and more are needing surgeries etc.
The only oil I'm still taking as a supplement is whatever is in my fat soluble supps, and then specifically Black Cumin Seed Oil for the preservation of my youthful immune system. All the other stuff is junk. For food I make, it's just light or regular olive oil (I take my polyphenols separately). Oh, and I gained 20 pounds of fat eating a serving a day of Chia seeds for the beneficial omega 3s, what a joke, maybe if you don't mind getting fat or if you're part of the 12% who literally can't get fat they're good for you... But that needs to be better understood. I can't stand people making themselves sicker with things they shouldn't be taking.
Oh, and the lowered blood glucose from fatty oils? More fat? More places to store and process sugar as fat and more blood is produced to revascularize the fat, therefore diluting one's blood glucose. This is basically the unaccounted for survival strategy that allows people to survive being fat longer than one might project. Also at cause for this are elevated, pre-diabetic glucose levels that aren't considered bad, just as risk... BMI and body weight, muscle or otherwise needs to be considered when generating blood glucose figures and determining whether that level is pathogenic. That's my hypothesis... junk science... food oil companies may well be the next tobacco companies.
