Why it is so easy to miss
The liver has no pain fibres in the tissue itself, so fat accumulation causes no sensation. Liver enzymes on a blood test can sit within the normal range while fat is accumulating. Most people who have it do not know, and most who find out did not go looking.
What makes it worth taking seriously is not the fat itself but where the process leads if nothing changes — inflammation, then scarring, and a cardiovascular risk that rises alongside it.
What drives it
Fatty liver travels with the same metabolic pattern as prediabetes: insulin resistance, abdominal fat and a diet high in refined carbohydrate and fructose. Two contributors get less attention than they deserve:
- Liquid fructose. The liver processes fructose differently from glucose, and sweetened drinks and juices deliver it faster and in larger quantities than whole fruit does.
- Late eating. The liver's fat-storage machinery is most active at night. Eating close to bedtime pushes fat towards hepatic storage rather than use, which is why meal timing shows up in liver outcomes and not only meal content.
- Refined carbohydrate load. Not fat in the diet — the association with dietary fat is far weaker than most people assume.
- Sedentary time. Independent of weight.
It is not only a problem for heavier people
Fatty liver is regularly found in people whose BMI looks unremarkable, particularly in South Asian populations where fat is carried viscerally. Healthness+ scores BMI against the Indian consensus thresholds — overweight from 23, obesity from 25 — for exactly this reason. Waist circumference tells you more here than weight does.
Where the Healthness+ assessment fits
Fatty liver rarely appears in isolation. The Health Risk Assessment scores gut, metabolic and activity signals together, and it is the combination — metabolic load alongside gut symptoms and low activity — that indicates the pattern rather than any single answer.
Common questions
Can fatty liver be reversed?
In its early stages, before significant scarring, fat in the liver is considered modifiable and often reduces with sustained changes to diet, weight and activity. Once fibrosis is established the picture is different, which is why finding it early matters. Your doctor, using imaging and blood work, is the one who can tell you which stage applies.
Can you have fatty liver without being overweight?
Yes, and it is not unusual in Indian populations. Visceral fat distribution matters more than total body weight, so a normal BMI does not rule it out.
Does fatty liver cause symptoms?
Usually not in early stages. Some people report fatigue or a vague discomfort under the right ribs, but most have nothing at all, which is why it is typically found incidentally on a scan.
Is alcohol the cause?
Not in non-alcoholic fatty liver disease, which is defined by its occurrence in people who drink little or no alcohol. Alcohol causes a separate form of liver disease, and the two can coexist.
