Beyond willpower: The biology of hunger Sarah Kennedy

Weight-loss drugs that target the hormone GLP-1 have rapidly reshaped the conversation around obesity, appetite and personal responsibility. But alongside the rise of powerful synthetic injectables, researchers are also exploring whether the body’s own appetite signals can be harnessed more naturally. At the heart of the debate is a simple question: are we eating too much because of weak willpower, or because of biology? As new approaches emerge, the challenge is to balance effectiveness, safety and long-term sustainability in tackling one of modern health’s most persistent problems. In this interview, Sarah Kennedy, founder of Calocurb, a New Zealand company which has developed a plant-based compound designed to naturally stimulate GLP-1, discusses the science of appetite control and how it compares to injectable drugs. --------------- Try Calocurb for yourself?
