“Oatzempic” is a play on words that is made up of the English word “oats” for oatmeal – and the name of a drug that is enjoying increasing popularity as a weight-loss injection. The diet simply means drinking a smoothie every day, consisting of oatmeal, water and half a lime.

The ingredients themselves are very healthy: oat flakes and lime provide many nutrients, and overall the drink is lower in calories than most other breakfast drinks or smoothies. Eating oatmeal every day can also be healthy and actually help you lose weight. However, the problems don't start with the ingredients, but with what isn't included. Without additional ingredients, important nutrients that the body needs are missing. Instead, you eat almost exclusively carbohydrates - and not even the healthiest ones. The quick promise of being able to lose up to 18 kilograms within two months is also problematic. Nutrition experts recommend losing a maximum of 1 to 2 kilograms per month.
