Have We Reviewed the U-Turn on Diet

In the late 20th century, official dietary advice made a sharp U-turn: fat, especially saturated fat, was labelled the primary dietary villain, and low-fat eating became the dominant recommendation. Decades later, obesity, metabolic disease, and confusion about what to eat have only increased.

Have We Reviewed the U-Turn? examines the evidence that followed this major shift. Written by Dr Samir Contractor, a laparoscopic and bariatric surgeon, the book reviews what happened after the low-fat guidelines took hold, re-examines the saturated fat debate, and asks whether the focus on isolated nutrients distracted us from a more important principle: the quality and context of real food.

This physiology- and evidence-informed guide helps readers understand where the advice went, what the data actually show, and why moving beyond nutrient fear toward whole-food patterns remains essential for metabolic health.
