In fact I cut carbs in February and every measure of my cardiovascular health is better: triglycerides down, HDL up, blood pressure normal, blood glucose down, etc - the only exception is LDL is slightly up. But we're to beleive that getting LDL down is worth jacking all those other things? Never again!
Read "The Big Fat Surprise" by Nina Teicholz if you want to get mad at how the scientific "consensus" on healthy eating came to be and how it has messed us up. Lots of parallels with global warming, actually. Scientists who came up with a theory (saturated fat -> hear attacks) that they cannot prove but if there's a chance it's true we MUST take action! Then demonize anyone who disagrees, pull their funding, and ruin their careers. And watch two generations of Americans get fat while cardiac issues get no better.
I had a slightly high resting glucose reading last year and immediately went low carb. Three weeks later, I got retested. My HDL went up, my triglycerides were cut in half, my glucose was normal and my LDL went up.
Now, there is a difference between VLDL and LDL, but they both register as LDL.
I have read than LDL will stay up for several months after starting a low carb, high fat/protein diet. It then settles back down.
It's as though your body is evacuating it.
