If you're on your own health journey, Kat said to make it fun! The only way you're going to stick with building a healthy body is if you actually enjoy the process, so find the joy in experimenting in the kitchen and in the gym.
She said you don't need to eat bland foods or torture yourself on the treadmill if that's not what you're into; try something new, like kickboxing, Zumba, or CrossFit. She suggested turning being healthy into a hobby instead of a chore; why not take a Mediterranean or vegan cooking class?
Kat also said you've got to do the real, inner work. "You can't just change what you're doing. You've got to change who you are, how you think, and how you show up for yourself," she added, "you're going to have to confront the limiting beliefs that have led to self-sabotage, the stressors that tend to trigger you, and the habits that threaten to keep you stuck."
Remember that it'll take patience, time, consistency, and intentionality, but when you master those deeper pieces, you'll be absolutely unstoppable not only on a journey to a healthier you, but also in the rest of your life.
