Luźna Dieta is a nutrition and wellness brand created by Karolina to help women lose weight and build healthier eating habits without extreme dieting, food obsession or an all-or-nothing approach. Drawing on her own experience of losing 10 kilograms without starvation diets, Karolina offers practical support for women who want to feel better in their bodies and make sustainable changes.

The brand’s Luźna Dieta app works like a pocket dietitian, with meal plans designed to fit users’ lifestyles, simple recipes and an automatic shopping list. Its food guidance focuses on tasty, vitamin-rich meals, including quick lunches and breakfasts that need no cooking. The online shop also offers app access, meal-planning resources such as ideas for breakfasts in jars, and individual support options, including monthly BASIC and three-month METAMORFOZA collaborations. Luźna Dieta presents healthy eating as enjoyable and manageable, helping users work toward their health and body goals in a flexible, everyday way. The brand also shares content through Instagram, Facebook and TikTok.
