The latest viral trend on TikTok and Instagram, dubbed “oatzempic,” involves blending oats with water or juice as a supposed natural weight loss aid. The name plays on Ozempic, a prescription diabetes drug known for appetite suppression. However, dietitians warn the drink is not scientifically supported for weight loss.
Oatzempic recipes vary, typically using one to two tablespoons of rolled oats blended with water, sometimes with lemon, lime, or cinnamon. Advocates claim it promotes fullness and reduces appetite, with some recommending it as a breakfast replacement or afternoon snack.
While oats contain beta-glucan, a soluble fibre that forms a gel and slows digestion, dietitians note that feeling full is not equivalent to sustainable weight loss. No studies have examined oatzempic specifically, and any weight loss may result from overall calorie reduction rather than the drink itself.
Experts emphasise that long-term weight management requires balanced nutrition and physical activity, not a single “magic drink.” They suggest a more nutritious option would be a smoothie with oats, fruit, nut butter, and milk, providing protein, healthy fats, and vitamins.
Drinking oatzempic in small amounts is generally safe, but it may cause bloating or affect medication absorption. Dietitians advise consulting a GP or accredited dietitian for personalised dietary advice.
