I tend to lose weight and feel extra good when I drink coconut milk shakes plus berries. Fairly often, I'll chuck in some banana or citrus as well. So it can be a fair amount of carb in there. What counts as low carb? Depends on who you ask and how bad/good your blood sugar metabolism is. I do think the scientific studies are fairly interesting and I keep an eye on them. Up regulation of this, down regulation of that, etc. I think it's important.
But on the flip side, we don't know much yet about how this really works. A vegan can find tons of little studies that they say support their position. ANd it all very obviously does. To them. It's very hard to read all the literature about any one food type and come up with a fair and balanced overall view. Instead, we all will tend to gravitate towards research that supports our view. So we need to consider that as well. That is why I try to watch the science and I also try to watch how something seems to effect people when they actually try it. How does it make me feel? How does my body seem to react to it. I try to temper that with the science. But there are many things we don't yet know on the science. So when someone tells me that fat plus carbs is bad, but I feel good and lose weight (which I want), even though supposedly it is not supposed to work that way. Well then I know some of the science is not totally worked out yet. And I have to consider that too.
