This is Sebastian David's story. He was once overweight and loved to eat donuts. When his father was diagnosed with motor neuron disease, he decided to get his own health in check. He turned his life around.

He stopped eating KFC chicken buckets and English pastries and followed a strict fitness regime.

After ditching junk food, he looks like this now.

Almost unrecognizable! He went from 202 pounds to 147 pounds.

He's even a male model right now.

You can do it too. You just need to be determined!
