About G-FiT

About Simon "Goliath" Lafontant

In 2023, I weighed 372 lbs. Over the next year, I lost more than 150 lbs while battling Crohn's disease and overcoming a lifetime of obesity and food addiction.

My transformation wasn't built on perfection—it was built on consistency, accountability, and learning how to win the small daily battles.

Today, I help others do the same.

Lost 160 Lbs

"If you’re looking to transform your life, this program is for you Goliath Fit isn’t just a coaching or a workout plan—it’s a community that pushes you to be your best. When I started my 90-day challenge, I had no real foundation, just a goal and the hope that I was making the right choice for my health. With Goliath’s program, there were no doubts. I saw progress every single day. Coach Simon was incredible—he’s been through the journey himself, which made his guidance and motivation even more valuable. He helped build a community where everyone supported each other, shared the same goal, and held each other accountable. That atmosphere kept me motivated, made me want to push myself, and encouraged me to help others do the same. If you’re looking to transform your life, this program is for you. If you commit and stay focused, you’ll accomplish so much more than just weight loss. I can’t recommend it enough—this is the only program that’s truly worked for me. The only barrier is yourself."

"I’ve been fat my whole life. Tried everything. Getting to work with you and feel like you actually understood me was life changing. This is the first time I’ve ever been able to keep it off and I’m the most confident I’ve ever been in my life."

Lost 220 lbs

"Simon Saved My Life I was diagnosed with diabetes in January of 2024. I weighed 410 pounds, had fatty liver disease, and high blood pressure. A bit over a year later, I now weigh 200 pounds at around 12% body fat. My A1C was last measured at 4.9 (better than average), my liver enzymes are normal, and my blood pressure is perfect. To say that this program changed my life is an understatement. The meal plan simplifies my nutrition and ensures that I get everything I need from food. The workouts are challenging, but not overwhelming. As someone who was terrified of setting foot in a gym, Simon’s videos gave me the confidence to not only walk in, but get to work. Simon’s guidance through my weight loss and continued health and fitness journey has been invaluable. He is dedicated to this program and the success of his clients. I can’t thank him enough."
