Diets usually bring quick and short-term success. In contrast, losing weight without the rollercoaster effect leads to slow and long-term results. This work is a guide to changing eating and lifestyle habits, providing genuine support for sustainable weight reduction filled with enjoyment. The first chapter includes a sensible and gradual dietary adjustment, the second chapter addresses the topic of weight loss, and the third section of the book explains how to maintain the achieved body weight. The many purely plant-based recipes in the fourth chapter are intended to help internalize the described dietary change more quickly and to enhance the enjoyment of the new wholesome way of eating. Additionally, the appendix of the book offers many more practical tips and guidance for a healthy lifestyle.
