Philosophies of the Practice
Being able to live a life with habits that are sustainable are far and few in today’s society. With so many diet trends and glorification of food, it can become hard to focus on the bigger picture and balance the joys of life (ie: yummy baked goods/restaurant foods) with healthy eating. Tiffany preaches an “all foods fit” a healthy diet mentality so that you no longer have to be controlled by it (mentally/emotionally/socially). This is the end to the years of dieting and tracking that no longer serves you.
