Lipid measurements after eight months on LCHF

Lipid measurements after 8 months (242 days) on low-carb, high-fat (LCHF) eating.

  • Total Cholesterol: 242 (mg/dL)
  • Direct LDL: 191 (mg/dL)
  • TC:HDL Ratio: 4.75
  • HDL: 51 (mg/dL)
  • Triglycerides: 93 (mg/dL)
  • TG:HDL Ratio: 1.82

These numbers have come in largely where I expected them to. The main surprise was a lower-than-expected (but still good) HDL.

My guess for total cholesterol count was 230, and so the actual measurement landed within about 5% of my guess. This is a relatively useless metric for heart disease risk, but it’s still popular, and so a lot of medical guidance continues to be based on this biomarker.

My HDL was lower than I expected it to be, but I attribute that to a lack of exercise during the past month due to a persistent cough and cold. I plan to retest in several months after resuming regular high-intensity exercise to see if that raises HDL (which would incidentally improve the TC:HDL and TG:HDL ratios as well).

The most important measurements for heart health and/or disease risk are triglycerides and TG:HDL ratio, and both of these are in the optimal (low) range.

A relatively high LDL combined with a low triglyceride measurement suggests (indirectly) the occurrence of LDL Pattern A, which is large, buoyant, non-oxidized LDL. This is more desirable than Pattern B, which refers to a preponderance of small, dense, oxidized LDL.

The relatively high LDL-P number suggests that I am a hyper-responder on a keto/LCHF diet. This result calls for further research and reading on my part.

The goal going forward is to:

  • increase HDL (mainly via exercise)
  • maintain low triglycerides
  • keep an eye on any movements LDL
  • retest in a few months
