Chanelle Hayes Tonic journey with a gastric sleeve
“Before weight loss surgery, I couldn’t cope with doing anything strenuous and I couldn’t spend time with my children in the way I wanted to. My eating was out of control, and I had been yo-yoing.
A year out from surgery, I’m a completely different person. Last year, my body fat percentage was in the morbidly obese category. Now, I’m in the healthy weight category.”
