A Being Patient report describes a DEXA scan estimating the writer’s visceral fat and reviews research connecting fat distribution with high blood pressure. Separate evidence links untreated high blood pressure with higher Alzheimer’s risk, but the report does not establish that hidden belly fat directly causes cognitive decline. The scan is not a brain-health test, and the writer’s individual result cannot predict a person’s future health.
Being Patient founder Deborah Kan reports that a DEXA scan estimated she had 0.41 pounds of visceral fat, prompting her to review research connecting deep abdominal fat with high blood pressure and vascular risks to the brain. The evidence discussed points to possible links along that chain, but does not show that a scan can diagnose brain health or that visceral fat directly causes dementia.
Kan says she paid about $50 for a DEXA scan at a local scanning business. The scan took about seven minutes, and its report compared her estimated visceral-fat amount with about 27,000 people in her age group. She says she ranked in the group with the lowest visceral-fat levels. That comparison comes from the scan report; Kan notes that people who pay for body scans may not represent the wider population.
She distinguishes the scan from an MRI: DEXA estimates the amount of visceral fat, while an MRI can show where fat is located. Her result is a personal measurement, not evidence that running caused her low estimate or that the number forecasts her brain health. The supplied report does not give the scan company’s methods or independent validation of its estimate.
For broader context, Kan cites a seven-year study of 903 Dallas residents who began with normal blood pressure. Researchers at UT Southwestern Medical Center mapped participants’ fat distribution; about one-quarter later developed high blood pressure. The report says body weight predicted risk, but after researchers accounted for where fat was carried, visceral fat was the only fat measure still associated with developing hypertension. This is an association, not proof that visceral fat alone caused the condition.
Blood Pressure Links Fat to Brain Risk
The potential relevance to the brain is indirect: visceral fat may be associated with high blood pressure, and high blood pressure can harm blood vessels that supply the brain. The Being Patient report cites research indicating that vascular health is one pathway of interest in dementia prevention. It does not establish that reducing visceral fat will prevent Alzheimer’s disease, or that an individual’s fat estimate can show whether their brain is healthy.
Kan also refers to a 2024 study of more than 31,000 older adults across 14 countries. In that study, untreated high blood pressure was associated with a 42 percent higher chance of developing Alzheimer’s. The report says the extra risk was not seen among participants whose blood pressure was controlled. That finding concerns blood pressure, not a direct test of visceral fat, and should not be read as proof that treating hypertension eliminates Alzheimer’s risk for every person.
The practical point in Kan’s account is that blood pressure is measurable and often has no symptoms. The article cites medical advice to monitor it, while stopping short of presenting a body scan as a necessary screening tool or a substitute for care from a qualified health professional.

From Fat Distribution to Hypertension
Kan’s report begins with a personal question: whether a relatively low body mass index and regular running necessarily mean she carries little deep abdominal fat. The scan offered an estimate, but the article does not claim that the result is a diagnosis or that a particular amount is ideal for every person.
The report connects three different kinds of evidence: a personal DEXA estimate, a study relating fat location to later high blood pressure, and separate research relating blood pressure to Alzheimer’s risk. Those findings address different questions. Taken together, they provide a reason to study how metabolic and vascular health may relate to brain outcomes, but they do not prove a single causal pathway from belly fat to dementia.
Kan says the Dallas study found that fat around the kidneys has also been examined in relation to hypertension, but that more research is needed to understand the interaction. Her cited expert, geriatrician Dr. Nate Chin, medical director of the Wisconsin Alzheimer’s Disease Research Center, emphasized blood pressure monitoring as a way to keep track of vascular health.
“The most useful thing my $50 scan did was point me to a new measurement to monitor my health.”

What a Fat Estimate Cannot Show
The relationship between visceral fat and brain health remains indirect in the research summarized by Kan. The Dallas study examined development of hypertension, while the international study examined blood pressure and Alzheimer’s risk. Neither, as described in the report, tests whether a DEXA-measured visceral-fat amount predicts dementia or whether lowering that amount prevents it.
The supplied article does not provide enough detail to independently assess the studies’ methods, participant characteristics beyond those stated, or the size of any effect tied specifically to visceral fat. It also does not identify the scanning business or explain how its estimate and age-group comparison were calculated. Kan’s low result therefore cannot be treated as a population benchmark or a forecast for other people.
It remains unclear how factors such as age, health conditions, medication and other lifestyle or biological differences shape these associations. No evidence in the report supports a goal of zero visceral fat. The article itself says that goal may be ambitious and unnecessary, especially for someone with a low estimate.

Monitoring Vascular Health
The report does not announce a new clinical recommendation or a follow-up study. Kan says she intends to focus on checking her blood pressure, drawing on Chin’s advice to measure it a few times a week. Readers considering home monitoring or a body-composition scan can discuss what the results mean with a qualified health professional; a DEXA estimate should not replace medical assessment.
The next evidence needed would clarify whether visceral fat itself predicts later cognitive outcomes, beyond its relationship with blood pressure and other health factors, and whether changes in fat distribution alter those outcomes. Until that evidence is available, the report’s clearest takeaway is limited: fat distribution and blood pressure are areas of ongoing research, while a personal scan result alone cannot tell someone the state of their brain health.

Key Questions
Can a DEXA scan tell me whether my brain is healthy?
No. In the report, DEXA is described as estimating visceral-fat amount, not examining the brain. Kan says an MRI can show where visceral fat is located, but the article does not describe either scan as a brain-health diagnosis.
The evidence summarized in the report does not establish that. One study linked visceral fat with later high blood pressure; separate research linked untreated high blood pressure with higher Alzheimer’s risk. These associations do not prove that visceral fat directly causes Alzheimer’s.
What did the Dallas study find?
According to Kan’s report, researchers followed 903 people who had normal blood pressure at the outset for seven years. About one-quarter developed high blood pressure, and visceral fat remained associated with that outcome after researchers accounted for fat location. The finding is an association, not proof of cause.
Does the report recommend trying to eliminate visceral fat?
No. Kan says zero visceral fat seems ambitious and may be unnecessary, and the article does not set a target amount for readers. A scan result should be interpreted in light of a person’s overall health with a qualified professional.
What can readers take away from the blood-pressure research?
The report emphasizes that high blood pressure can go unnoticed and cites research connecting untreated hypertension with higher Alzheimer’s risk. It describes blood-pressure monitoring as a way to track vascular health, but personal monitoring and treatment decisions should be discussed with a health professional.
