Weight-loss drugs such as Ozempic, Wegovy and Mounjaro work primarily by reducing hunger. They mimic a hormone the body already produces called glucagon-like peptide-1 (GLP-1), which helps regulate appetite and feelings of fullness. By slowing how quickly food leaves the stomach and acting on appetite centres in the brain, the drugs help people feel full […]

PeopleImages/Shutterstock Every January, internet searches for the terms “diet” and “weight loss” surge, gyms become busier and diet trends spread across social media. But research shows that most people who try the latest quick-fix plan do not keep the weight off. Focusing on weight alone can overshadow other changes that improve health in more reliable […]

A large Danish study tracking more than 85,000 adults has found that people with a BMI below 18.5 were nearly three times more likely to die early than those in the middle to upper end of the so-called “healthy” range.

Holidays should be about relaxing, enjoying yourself and making memories – not obsessing over a “perfect” eating plan. A healthy diet is built over months and years, not in a single week (or two). Instead of restricting what you eat, a better approach is to add healthy extras to your holiday meals. This way, you […]

From collagen powders to immunity gummies, supplements are everywhere – in our Instagram feeds, on supermarket shelves and filling our bathroom cabinets. Promising better sleep, glowing skin, sharper focus or even a longer life, they’re marketed as quick fixes for modern health woes. As a nutritionist, I’m often asked whether supplements are worth the money […]

How much does your weight really say about your health? Probably less than you think.
