Kail Lowry has lost a lot of weight since the summer of last year.

'Teen Mom 2' Star Kailyn Lowry Started Her Own Clothing Line

After several months of hardcore exercise and a strict diet, the Teen Mom 2 star shed a substantial amount of weight, and in a new Instagram post, she gave fans a look at her June 2014 body, compared with her current frame.

"HAPPY HUMPDAY. 20 lbs to go! Left was today, right was taken June 2014," Lowry captioned the Instagram photo, shared online on Wednesday.

Kailyn Lowry Shares Photos Of Dramatic Weight Loss

Earlier this year, Lowry shared another before and after photo of her weight loss, which featured the changes in the Teen Mom 2 star's face.

On Instagram, along with the Jan. 2015 photo, Lowry wrote, "First week of October on the left and last week on the right. Nothing is harder than getting my eating habits down. It's been a long and slow process. Still trying to kick my addiction to food but working on it, and working out, nonetheless."

Around the time Lowry's photo was shared, In Touch Weekly claimed the mother of two's weight loss was the result of help from a personal trainer, healthy eating and regular exercise.

Lowry welcomed her first son, Isaac, in Jan. 2010, with her ex-boyfriend Jo Rivera, and her second child, Lincoln, in Nov. 2013, with husband Javi Marroquin.

Kail Lowry returns to MTV in Teen Mom 2 season six on July 9 at 10 p.m. on MTV. Rivera and Marroquin will also been seen in the upcoming episodes.
