Triglycerides and HDL: one ratio instead of total cholesterol
Two women with LDL of 3.8. The first has triglycerides of 0.7 and HDL of 1.9. The second — 2.4 and 1.0. The same “bad cholesterol,” but the heart attack risk differs several-fold — because different particles stand behind that one LDL number: large and harmless in the first woman, small and dense in the second. You can distinguish them without expensive tests — with one division. Section — cholesterol and the heart.
What the ratio shows
Triglycerides rise from sugar, fructose, and insulin resistance; HDL falls from them as well. When triglycerides are high, the liver assembles LDL into small, dense particles — they penetrate the vessel wall more easily and oxidize. When they are low, the particles are large, “fluffy,” and their atherogenicity is significantly lower. The TG/HDL ratio is an indirect but reliable marker of particle size and insulin resistance, and studies show that it predicts cardiac events better than LDL.
Ranges
| TG/HDL (mmol/L) | TG/HDL (mg/dL) | Assessment | Particles |
|---|---|---|---|
| below 0.9 | below 2 | excellent | large |
| 0,9-1,7 | 2-4 | good | mostly large |
| 1,7-2,7 | 4-6 | risk | mixed |
| above 2.7 | above 6 | high risk, insulin resistance | small dense |

What drives each one
Triglycerides down: zero sugar and fructose — juices, honey, and fruit in quantity; less flour and starch; no alcohol; omega-3 2-3 g; a fasting window. This is the most responsive marker — down by a third in three months. HDL up: dietary fats — olive oil, avocado, fish, eggs, cheese; strength training and walking; quitting smoking; and time — HDL rises more slowly, over 3-6 months. LDL in this picture is cholesterol on a low-carbohydrate diet; read the paper in full — how to read a lipid panel.
Mistakes
- Looking only at total cholesterol and LDL
- Lowering triglycerides with “low-fat” foods — they contain sugar
- Being afraid of fats that raise HDL
- Getting tested non-fasting — triglycerides are twice as high after eating
- Expecting HDL in a month — it needs six months
Frequently asked questions
Triglycerides 2.5 — what comes first?
Juices, honey, sugar, alcohol — zero. After 3 months, it is usually below 1.5. This is the fastest marker.
Low HDL with normal triglycerides?
Often genetics or too little movement. Strength training, walking, fatty fish, quitting smoking. And time.
Does this replace ApoB?
No, ApoB is more accurate — it counts particles directly. But TG/HDL is included in every lipid panel and provides 80% of the information for free.

Insulin drops — water leaves, and blood pressure decreases by 5-15 over several weeks. What this means for people taking medication, and why salt is not the enemy.

- Energy crashes after eating: why you feel sleepy after lunchLunch — and an hour later you can't work. It's not that you "overate"; it's a roller coaster: blood sugar rises, insulin overshoots, and blood sugar drops below normal.

- Metabolic flexibility: why some can go 16 hours without eating while others «crash» after threeA healthy body switches from carbohydrates to fat overnight. A body fueled by sugar six times a day has forgotten how: without food for three hours — shaking and brain fog. It’s not character, but a rusty switch, and it can be fixed in a month.
