Mary Mouser Experienced Weight Gain After Using Insulin Pump To Treat Diabetes

Mary Mouser plays the role of Samantha LaRusso in Cobra Kai.

Mary Mouser discovered weight issues after she was diagnosed with Type 1 diabetes.

28 years old, Mary Mouser was born on May 9, 1996, in Pine Bluff, Arkansas, United States.


  • Mary Mouser was diagnosed with Type 1 diabetes at the age of 13, due to which she started using an Insulin pump.
  • She is raising awareness regarding diabetes and encouraging the young generation suffering from the disease.
  • Mouser was criticized by her fans as her body shape did not fit in the Karate series.

Mouser is an actress best known for her role as Samantha LaRusso in the Netflix series Cobra Kai and Lacey Fleming in the ABC series Body of Proof.

Recently, Mary and Tyler Posey have been leading the cast of the Simon & Schuster Original Audiobook Know Your Newlywed.

It was written by Heather Taylor and Hillary Nussbaum, with Elena Armas serving as executive producer.

Mary Mouser’s Weight Gain Is The Side Effect Of Insulin Therapy

One of the main cast members of Cobra Kai, Mary Mouser, has had noticeable weight gain over the years.

Mouser was thin during the first season of Cobra Kai, but as the show progressed to the next season, she started to gain weight.

Moreover, her fans didn’t appreciate her for her bigger and plumper body. We can clearly see that her belly sticks out from her jeans, and her figure looks very rounded.

She has faced much criticism as her physique does not fit the Karate series. One of the fans said,

I think she could stand to lose a little weight. I mean, she is supposed to be this athletic badass, but she is at least 15 lb overweight. In fact, I don’t know how she is still so round with all the training she must be going through for the series

Cobra Kai fans can criticize Mouser as much as they want for her round body shape, but it won’t change her weight or body shape as she is suffering from a chronic disease.

Mouser has been living with Type 1 diabetes since the age of 13. She started using insulin injections and then switched to an insulin pump.

Later, she was introduced to the Tandem diabetes Car t: slim X2 pump at 17.

Currently, she needs one unit of insulin for every 15 carbs. Since she started taking insulin, her control over food and weight has ended. Mouser said,

Never again that I would be able to just run up and grab a slice of cake and start eating it and then move on with my day. That there would have to be a step before that, which is testing my blood sugar and then delivering the insulin and then waiting ten minutes, and then being able to eat the cake and hoping I corrected enough for it. Then doing some tests afterward, and maybe I didn’t give enough insulin and then I have to give another shot of insulin and all of these things to come along with eating.

Mary Mouser

Mary Mouser weighs around 60 kg, which is not a compatible weight for a Karate athlete.

Mary still uses pumps by wearing them under the Karate customer while shooting Cobra kai as she asked wardrobe designers to take her pump into consideration.

It helps her spend more time in her target glucose range and has given her the flexibility to focus on daily work and activities.

However, she might never have a perfect athletic body shape to get fans’ appreciation.

Currently, Mouser is helping raise awareness of Type 1 diabetes and encouraging young people who are living with the condition.
