While thick, chunky animals might seem cute, animal obesity is actually becoming a big issue nowadays. The wrong diet, laziness, and lack of movement can all result in excessive weight gain and can come along with a whole mess of health issues. The fluffy characters in our article and their owners did a great job “de-chunking” and fighting off any extra pounds they had.

We at Bright Side were astonished after seeing a chunky lizard — yes, even they can carry extra weight. We applaud each and every animal in this compilation and would like you to appreciate their hard work too.

“From 23 lb to 13 lb — still have a bit to go, but my owner no longer refers to me as his chunky boy!”
