Also called: Dyslipidemia
Relief and prevention
Strength
Blood lipids that raise cardiovascular risk over decades. Exercise is genuinely useful here but it shifts triglycerides and HDL far more than it shifts LDL, which is worth knowing before judging it by the wrong number.
How common: ~38% of US adults have high total cholesterol or are on treatment
What it is
Cholesterol is carried around the body in particles. LDL particles deposit cholesterol in artery walls and are the main driver of cardiovascular risk; HDL particles carry it back to the liver; triglycerides are a separate fat that travels with them and rises steeply with excess energy intake and insulin resistance.
What matters for expectations is that these respond differently to exercise. Triglycerides fall substantially and HDL rises modestly with regular training. LDL barely moves without weight loss or dietary change - so someone judging their exercise programme purely on their LDL number will conclude it did nothing when it may have changed their risk considerably.
What it feels like
- Nothing at all - it is found on a blood test, not felt
- Occasionally fatty deposits around the eyelids or a pale ring around the iris in severe inherited cases
- Usually discovered alongside high blood pressure, raised blood sugar or central weight gain
- In familial hypercholesterolaemia, sometimes tendon thickening at the Achilles or knuckles
- The first symptom in most people is a cardiovascular event, which is the whole reason for treating a number
What causes it
Most people have more than one of these at once, and they feed each other. Read the
list looking for the two or three that sound like your week rather than for the one
true answer — the ones that describe you are the ones worth acting on.
- Low muscle mass and inactivity
- Muscle is a major site of fat oxidation. Less active muscle means triglycerides clear more slowly from the blood and the whole lipid profile shifts unfavourably.
- Liver handling of lipids
- The liver produces, packages and clears lipoproteins. Insulin resistance and fat accumulation in the liver change that handling directly, which is why fatty liver and dyslipidaemia travel together.
- Central body fat
- Visceral fat releases fatty acids straight into the portal circulation, giving the liver a constant supply to package into triglyceride-rich particles. Waist size predicts lipid abnormalities better than weight does.
- Diet composition
- Saturated fat raises LDL; refined carbohydrate and alcohol raise triglycerides substantially. Dietary cholesterol itself matters far less than was believed for decades.
- Genetics
- Familial hypercholesterolaemia affects roughly one in 250 people, produces very high LDL from birth and dramatically raises early cardiovascular risk. It is massively under-diagnosed and it does not respond adequately to lifestyle alone.
- Alcohol
- Alcohol raises triglycerides in a dose-dependent way and it is one of the fastest lipid changes to reverse - triglycerides often fall noticeably within weeks of cutting back.
- Underactive thyroid
- Hypothyroidism raises LDL and is a common, easily tested and easily corrected secondary cause. It is worth excluding before treating the number.
- Type 2 diabetes and insulin resistance
- The characteristic pattern is high triglycerides, low HDL and small dense LDL particles, which are particularly atherogenic. Improving insulin sensitivity improves all three.
- Some medications
- Steroids, some diuretics, beta blockers and certain immunosuppressants all affect lipids. Worth reviewing when a profile changes unexpectedly.
- Menopause
- LDL rises and HDL falls after menopause as oestrogen declines, which is part of why cardiovascular risk in women rises steeply in the decade afterwards.
Who tends to get it
- Anyone with a family history of early heart disease or very high cholesterol
- People with central weight gain, type 2 diabetes or metabolic syndrome
- Postmenopausal women
- Anyone with an untreated underactive thyroid
- Regular drinkers, particularly for triglycerides
What makes it worse, and what settles it
Makes it worse
- Inactivity, which raises triglycerides and lowers HDL together
- Regular alcohol, particularly for triglycerides
- High refined carbohydrate intake
- Judging an exercise programme purely by LDL, which is the number it moves least
- Stopping a prescribed statin because the number improved, which is a decision for the prescriber
Settles it
- Regular aerobic exercise, which lowers triglycerides and raises HDL reliably
- Resistance training, which improves insulin sensitivity and the whole cluster with it
- Losing central fat, which is what actually moves LDL
- Cutting alcohol, which shifts triglycerides within weeks
- Getting thyroid function checked if the profile is unexpectedly poor
What actually helps
The short version: Hepatic lipid handling and low muscle mass; exercise shifts HDL and triglycerides more than LDL
Strength work: Full Body; combined resistance and aerobic
Stretching: Not a driver
Massage: Not a driver
Also worth doing: Aerobic volume matters more than intensity here
What the evidence says: Exercise reliably lowers triglycerides and raises HDL; LDL change is small. Honest framing: adjunct to diet and medication, not a replacement.

qFIT already has this one built. It runs massage first, then stretching, then
strength — the order that works on a body that is already sore — and every
activity in it carries the reason it is there.

Get it checked if…
Chest pain or breathlessness on exertion - stop and get assessed
And whatever the body part: chest pain or unusual breathlessness on
exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and
unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or
one calf that is swollen, warm and painful. Any of those, stop and get assessed.
How it usually goes
Triglycerides respond within four to twelve weeks of regular exercise and often dramatically; HDL rises modestly over three to six months; LDL needs weight or diet change to move much. All of that is worthwhile even though the headline number is the least responsive. Exercise also reduces cardiovascular risk through routes that never show up in a lipid panel at all - blood pressure, insulin sensitivity, inflammation and arterial function - so the panel understates the benefit.
Prevalence basis: NHANES
Others the same routine covers
These share the Weight, Cholesterol & Metabolic Health routine, so the work is the same. If one of them also
sounds like you, that is a reason to expect more from it, not less.
This is general information, not a diagnosis, and it cannot examine you.
If it matches you, use it to ask better questions of a clinician rather than to replace one.
