The LMHR pattern is being actively studied. High LDL in lean, metabolically healthy people on low-carb diets doesn't always behave the way it does in the general population. Early imaging work has found LDL/ApoB didn't track with plaque progression in this group the way it usually does.

That said, the researchers behind it are clear the data is still early and small-scale. It's not settled science yet. That's why we look at the full picture— ApoB, HDL, triglycerides together— and when appropriate, a coronary artery calcium score for a clearer read on actual plaque.

We’re tracking the research as it develops, and we’re glad you are too.

This is the iron cheat sheet you’ve been waiting for.

Here’s what to eat, how to absorb it, and what to test over time. 🧵

[Function Health @function]

To support iron absorption

Pair with:
✅Vitamin C—it significantly enhances non-heme iron absorption—think citrus, bell peppers, tomatoes alongside plant-based sources.
✅Meat, poultry, or seafood alongside plant-based iron sources.
✅Cooking in cast iron—it can increase iron content of food.

Avoid pairing with:
❌Tea
❌Coffee
❌Wine
❌Calcium-rich foods
