Kat Ostroumova

Kat was born in Irkutsk, Russia. At the age of nine, she moved to Toronto, Canada with her family where she still resides.

At the age of 17, Kat was diagnosed with hyperthyroidism – an overactive thyroid disease - that causes the heart to beat fast and irregularly and the person to feel nervous, anxious, and weak amongst other severe symptoms. After unsuccessful radioactive iodine treatment, which lowers the thyroid hormone level to its regular production, her condition morphed into hypothyroidism - an underactive thyroid disease. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, slowed heart rate, joint and muscle pain, cramps, weakness, recurrent urinary and respiratory tract infections just to name a few.

After years of struggle, major weight gain, and weighing 183lbs at her heaviest, Kat decided to take control of her life by prioritizing her health and wellbeing above everything else. She changed her mindset which allowed her to restructure her time, diet, exercise and overall lifestyle.

After losing over 40lbs, Kat went on to compete at the WBFF (World Beauty Fitness and Fashion) show, where she earned multiple top three finishes in multiple categories.

She has successfully taken back control of her life from hypothyroidism and has now dedicated her life to others suffering from the same affliction. Globally, people from all walks of life have reached out to Kat asking for help and guidance with hypothyroidism, weight loss, and mindset coaching. This was the birth of Kat International Fitness™.

The mission at Kat International Fitness™ is to inspire, motivate and empower women who are struggling with the mental and physical effects of hypothyroidism, hormonal imbalances and weight loss by implementing proven custom strategies and accountability touchpoints.

Currently, Kat is operating a successful online coaching business that helps thousands of women worldwide meet their health and fitness goals through custom programs, her own personal app, and a line of pro-grade resistance bands.

Kat has been named Canada’s Top Hot and Fit 100 by Inside Fitness magazine, has been featured in Fit and Firm Magazine, numerous publications, podcasts, TV and radio interviews, and is also a sponsored athlete for Rival Nutrition Canada and USA.

The one thing that stands out about Kat is that her beauty shines inside and out. Her positivity and motivation is empowering. This girl takes nothing for granted and no doubt she is ready to take on whatever comes her way. She is not done telling her story, this is just the beginning.
