At the City and Communal Public Library “TAMA”, there was an author’s meeting with Aneta Piątek-Zwierzak, the founder of Fitnessacja, which has been operating in Brzeg Dolny for 13 years, as a fitness instructor and personal trainer, dietitian, and author of e-books on healthy eating. The conversation was conducted by Jolanta, who is a trainer and instructor at Fitnessacja. Participants of the meeting learned about the pillars of healthy eating and how to interpret product labels. Mrs. Aneta shared with the library guests helpful applications for monitoring calories, water intake, and micro- and macronutrients. The discussion focused on the benefits of hydrating the body, physical activity, common mistakes when introducing new eating habits, as well as symptoms of insulin resistance or hypothyroidism. Everyone could share their experiences and get answers to their burning questions. The meeting was an opportunity to receive access codes to two e-books and vouchers for Fitnessacja, which were raffled off among the meeting participants.
