The quote about perception change and health could be attributed to a famous psychologist, nutritionist, fitness trainer, or motivational speaker, all of whom value holistic health over just weight loss.
Step-by-step explanation:
The quote “You have to change your perception. It's not about weight—it's caring for yourself on a daily basis,” could be attributed to several types of professionals who focus on well-being and self-care, including a famous psychologist, a nutritionist, a fitness trainer, or a motivational speaker. All of these professionals emphasize the importance of healthy living and mental well-being over the mere aspect of weight loss. While a nutritionist specializes in the science of food and a fitness trainer focuses on physical exercise, both psychologists and motivational speakers work towards changing mindsets and beliefs surrounding health and self-care.
