Down 40 pounds in TWO YEARS. Let's do some quick math. The difference between the two pictures is 700 days. 40 pounds x 3500kcal/lb of fat = 140000 kcal. 140000 kcal / 700 days = 200kcal a day.  I would estimate that she is a good 270 lbs at 5'6" in the first picture. Her Total Daily Energy Expenditure would be about 2400 calories a day for being a couch potato with little to no exercise. So she literally still ate 2200 calories on average every day for 2 years, or what a normal human should be close to eating anyway.  Now I'm all for weight loss and shit, but if you're going to post progress pics, I would expect BIG results. If she would have been down, I don't know, lets say 100lbs in 2 years, that's a lot more respectable than 40lbs. It's really not difficult to lose 10 lbs of fat in a month, or at LEAST 5lbs a month if you're just sticking to a -500 calorie diet. So good for her, she didn't eat an extra snickers bar or drink that extra can of soda for 2 years. She would have seen way better results had she been doing a real diet. I personally don't like progress pics until they have something to actually show for it, like going from a BMI of 50 to a BMI of under 30.
