Shreveport‑area residents who follow health influencers on TikTok may be getting misleading information about insulin resistance, a condition that often goes unnoticed until a blood test is performed. Dr. Tom Davis, a primary‑care doctor with more than ten years of experience and medical director at the digital health service Kry in London, says the viral videos that point to swollen ankles, bloating or other vague symptoms are not a reliable way to diagnose the disorder.
What insulin resistance really is
According to Dr. Davis, insulin is a hormone produced by the pancreas that acts like a key, allowing glucose from food to move out of the bloodstream and into cells for energy. When the cells stop responding properly, the pancreas must produce ever‑more insulin to keep blood sugar levels normal. This mismatch is what doctors call insulin resistance.
“Insulin resistance is measured in blood, not judged from a photo,” Dr. Davis explains. “You cannot diagnose a hormone problem by looking at someone’s body.”
Why the TikTok trend is problematic
Videos circulating on the platform often feature influencers pointing to body parts—such as swollen feet or a bloated belly—and claiming those are clear signs of insulin resistance. Some even assert they can diagnose the condition simply by looking at a person.
Dr. Davis refutes these claims, noting that swelling in the feet can stem from many other causes, including prolonged standing or circulation issues. “Body weight is a genuine risk factor, but it’s not a diagnosis,” he adds. “Plenty of people carrying extra weight have completely normal insulin sensitivity, and plenty of slim people have insulin resistance—it’s called TOFI, thin‑outside‑fat‑inside. The only way to actually know is a blood test, not a video pointing at a body. “
Real visual clues and prevalence
The doctor points out that the only visual indicator sometimes associated with insulin resistance is a skin condition called acanthosis nigricans—dark, velvety patches around the neck, armpits or groin. Even this sign is far less dramatic than the TikTok footage, which is why it rarely appears in short‑form videos.
Data from Diabetes UK show that 6.3 million people in the United Kingdom live with pre‑diabetes, largely driven by insulin resistance, and more than 12 million adults—about one in five—have diabetes or pre‑diabetes. Despite these numbers, the condition often produces no obvious symptoms early on, making it easy for misinformation to spread.
Evidence‑based steps to improve insulin sensitivity
While the viral claims that specific foods like avocado or olive oil can magically reverse insulin resistance are overstated, Dr. Davis emphasizes that lifestyle changes do move the needle. “Losing excess weight, especially around the middle, being more active—particularly building muscle—and improving sleep are all proven ways to boost insulin sensitivity,” he says.
These adjustments not only lower the risk of developing type 2 diabetes but also tend to increase energy levels, reduce sugar crashes, and improve blood pressure and cholesterol numbers.
Takeaway for viewers
For anyone concerned about insulin resistance, the safest course is to consult a medical professional and request a blood test. Relying on quick‑fix videos can lead to false reassurance or unnecessary alarm. As Dr. Davis notes, “The changes that move the needle aren’t exotic; they are grounded in solid, everyday habits that support overall health.”
