I started last year around June at over 270lbs and now weigh 169lbs. I'm 5'10" and work in IT and sit for long periods of time. I lost weight by walking, getting a Garmin watch to count my steps and challenge others, and logging my food into myfitnesspal. People often asked me how I have lost so much and I simply tell this, Eating right, exercising, and being persistent.
Ive included a pic of me at 240lbs from 2017 next to me now at 170lbs. I dont have any pics of me at 270 because I was camera shy.
