Lisa McKay used to drink 20 cans of Coke a day. Can you imagine it? It's 2800 calories. Now let's add a couple of hamburgers and we have the reason why she weighed 280 pounds (127 kg) at the age of 24. Lisa McKay was forced to book two airplane seats and she couldn't walk more than a couple of yards without getting breathless. Unbelievable? But the most unbelievable part is yet to come. Lisa has decided to make some changes to her life. She underwent a gastric band operation, stopped drinking Coke and eating hamburgers. And it has led to amazing results. Now she eats only 1000 calories a day and weighs only 140 pounds (63 kg) instead of 20. It's amazing.
