A small snack can be quickly consumed. Here a half jam sandwich, there a banana, and in between, a piece of chocolate. We think it hardly matters and wonder where the extra pounds come from. After all, we always eat just a little. This can be misleading, as the total often adds up to significant amounts. Anyone who wants to uncover their dietary mistakes should keep a food diary, as the NDR nutrition docs recommend to their patients. Whether it's about losing weight, food intolerances, or simply adopting a healthier lifestyle: writing it down is the first step to revealing personal weaknesses and developing a personal action plan. The food diary from the renowned TV doctors offers not only templates for recording but also numerous tips and guides to make individual dietary changes easier: from information on healthy fats and good carbohydrates to clever strategies against cravings.
