For my family only

This site is curated for my own family members. It is not a recommendation or a diet plan for anyone else. Do not change your diet, start fasting, or change any medicine without your own doctor's advice. We are not responsible for any consequences of following this information without proper medical supervision.

Read this first: This page is education, not a treatment plan. If you take insulin, a sulfonylurea (glipizide, glimepiride, gliclazide), an SGLT2 inhibitor (Jardiance, Farxiga, Invokana), blood pressure pills, warfarin or lithium, or if you are pregnant, breastfeeding, under 18, have kidney disease or a history of an eating disorder, do not start a low-carb diet or fasting without your doctor.

within the common cut-off borderline outside the range: discuss with your doctor no result or no standard range

1Notes on the ranges#

  • HbA1c and fasting glucose: ADA 2026 cut points for prediabetes and diabetes[1].
  • Lp(a): under 75 nmol/L (about 30 mg/dL) low, 125 nmol/L (about 50 mg/dL) or more high[2]. Test once in your life. If your report is in mg/dL, choose that unit above; the tracker converts approximately (the two units do not convert exactly).
  • Units: glucose in mmol/L is converted at 18 mg/dL per mmol/L, and B12 in pmol/L at 1 pg/mL = 0.738 pmol/L. The table rows show the US unit.
  • Green dots mean "within the common cut-off", not "your target". Your doctor may set tighter targets, especially for LDL if you have diabetes or heart disease.
  • ALT: "truly healthy" upper limits of 33 U/L for men and 25 for women, lower than many lab report ranges[3].
  • eGFR and urine ACR: kidney staging[4].
  • B12: the diabetes prevention trial used 203 pg/mL or less as low[5]; many labs treat 200 to 300 as borderline.
  • Triglycerides, HDL, LDL, uric acid, TSH, blood pressure: commonly used US clinical thresholds; your doctor may set different targets based on your overall risk.
  • ApoB and non-HDL: no single target applies to everyone; watch the change from your baseline.
