Where this comes from
The Low GSF Diet is not a new invention. It is old, solid science put together in a simple way. The hard work was done over decades by scientists, doctors, and writers. This page names them.
The people on this page shaped the thinking behind this site. They did not build it, review it, or endorse it. If their work interests you, read it straight from them.
David Jenkins
A scientist at the University of Toronto. In 1981 he invented the glycemic index, the first real way to measure how fast a food raises blood sugar. Twenty years later he created the Portfolio Diet, a way of eating that lowers cholesterol with food. Look at those two ideas side by side. They are the two halves of the GSF score. Both trace back to one person.
The PREDIMED researchers
A team of doctors in Spain ran one of the largest diet experiments ever done. About 7,500 people at risk for heart trouble ate Mediterranean style, with olive oil and nuts, for years. The result: roughly 30% fewer heart attacks, strokes, and heart deaths. That eating pattern is the base GSF is built on. See the study.
Jessie Inchauspé
A biochemist who made blood sugar something normal people talk about. Her book Glucose Revolution taught millions that spikes matter, and that simple moves like eating vegetables before carbs can flatten them. The habits on this site, like walking after meals and putting protein first, come from the research she made famous.
Peter Attia
A doctor and the author of Outlive. He is a big reason ordinary people now ask their doctor for an ApoB test. ApoB counts the particles that clog arteries, and it is exactly what the saturated fat half of GSF looks after.
Thomas Dayspring
A doctor who spent decades studying blood fats and teaching other doctors what he learned. His message is simple: what clogs arteries is the number of ApoB particles, and saturated fat pushes that number up. That message is baked into half of the GSF score.
Gil Carvalho
A doctor and scientist who explains nutrition studies on a YouTube channel called Nutrition Made Simple, calmly and study by study. He is one of the few voices saying what this whole site says: blood sugar and saturated fat both matter, and fixing one while ignoring the other is a bad trade.
USDA FoodData Central
The United States government's public food database, free for anyone to use. When you search a food here, this is the first place we look.
Open Food Facts
A food database built by volunteers around the world. Think Wikipedia, but for food labels. It powers our barcode scanner. Their data is open, and we use it under the same open license they share it with.
If a scientist or writer shaped low-glycemic or low-saturated-fat eating and belongs on this page, tell us.
