The Claim
The homeoviscous adaptation to dietary lipids (HADL) model proposes that increases in low-density lipoprotein cholesterol in response to saturated fat intake represent a physiological adaptation to maintain cell membrane fluidity rather than a pathological process in healthy individuals without metabolic dysfunction.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy people without metabolic dysfunction, rising levels of LDL cholesterol after eating saturated fat are a normal biological response to keep cell membranes fluid, not a sign of disease.
See the scientific wording
The homeoviscous adaptation to dietary lipids (HADL) model proposes that increases in low-density lipoprotein cholesterol in response to saturated fat intake may represent a physiological adaptation to maintain cell membrane fluidity, rather than a pathological process, particularly in healthy individuals without metabolic dysfunction.
When saturated fats enter cell membranes, they make the membranes stiffer. To keep the membranes flexible and working properly, cells pull cholesterol from the blood into the membranes. This lowers the amount of cholesterol in the blood, so the liver makes more LDL particles to replace it, causing LDL cholesterol levels to rise. This is a normal adjustment, not a sign of disease.
What the research says
1 studyWhen people eat more saturated fat, their bodies may raise LDL cholesterol not because it's bad, but to help keep cell membranes flexible — like adjusting the oil in a car engine for different weather. This is a normal, healthy response in people without other health problems.
