Kat is a phenominal coach who tells it to ya how it is.
Kat is a phenominal coach who tells it to ya how it is. Phat Kat fitness is a well rounded program with one on one coaching, mindset work, a nutrition plan without all the extra ingredients, and strength training targeting your body type. Since I started working with her early this year, I have lost over 12 lbs, released a lot of inflammation and bloat, my hip pain has gone away and my foot pain is so much better, and I have become a stronger woman in mind and body. My biggest struggle has been losing weight in my gut.. I learned I wasn't eating nearly enough - goodbye to rabbit food and hello healthy proteins and whole foods. It's a slow process for me, but I'm here for the long haul, making consistent healthy choices and choosing a lifestyle that will serve me now and in 20 years!! To all my perimenopausal friends - how you treat your body now is what you will experience in your 50's, 60's and beyond. Your health is your Wealth!! Let's become better together for generations to come!!

It's a great place if you suffer from chronic fatigue.
It's a great place if you suffer from chronic fatigue. Tanmay has suffered from this himself. So, it is not coming from "a book". It is coming from someone, who understands you, and solved it for himself. He is not trying to fix the symptoms, he goes deep into the root causes and helps identify and eliminate them.
