Low-carbohydrate eating has gone from fringe idea to mainstream diet trend in less than two decades, and this Australian documentary asks whether the science actually backs it up. The film opens with a quick history lesson: when dietary fat was cast as the villain in the late twentieth century, food manufacturers compensated by loading products with sugar and refined carbohydrates, a shift several nutrition researchers now link to rising insulin resistance and obesity. From there it puts the low-carb backlash on trial, interviewing doctors and scientists who credit carbohydrate restriction with weight loss and improvement in chronic conditions, alongside others who warn that cutting out whole grains and fruit removes foods long considered essential to a balanced diet. No single verdict gets the last word. Instead the film lays out where the research genuinely conflicts, letting viewers see how the same body of evidence produces opposite dietary advice depending on which expert is reading it.
