A father has literally gone up and down in weight, shedding 100 lbs. after getting stuck in a roller coaster car. Richard Jeferies, 48, tipped the scales at 24 stone (336 lbs.), but didn't realize he had a problem until he became wedged in a car on the ”Sonic Spinball” ride at Alton Towers. The father of four was at the theme park with his daughter Isabella, 8, when he struggled to fit into the ride.

Staff had to stamp on the bar to make it lock around Richard, which meant he was struggling to breathe. Then, when the carriage finally came to a stop, overweight Richard was left wedged in the seat and had to be heaved out by staff. He says he was spurred on by the embarrassing experience and immediately launched a fitness regimen of eating salads and hitting the gym. In just over a year, he has shed 114 lbs. and now weighs a much healthier 230 lbs.

Richard, who lives with his wife Fiona, 45, who is a full-time mother with four children, had considered weight-loss surgery in the past. However, after he joined Weight Watchers, dramatically changed his diet, and began exercising, the weight started to drop off.
