A photo from 2010.
In 2010 she weighed roughly 95 kg (209 lb). The second pic was from a few weeks ago and it's around 72 kg (158 lbs).
Her main reason for the weight loss was "I have never, ever felt confident in a pair of shorts let alone a bikini", so after years of feeling uncomfortable she committed herself to a diet in 2010.
The pic on the left is her after five years of dieting (2015). . The right pic is her a year later after working out all year.
This is another photo of 2015 vs 2016 and she had this to say: "I've been very large for a very long time - never dreamed I could wear anything like this! So I bought this bikini a couple of weeks ago to tan in for summer. Today my butt is one of my best features... it's probably prettier than my face haha; and I've done a lot of hard work and thousands of squats to get it this way so let's show that baby off! "
