A morbidly obese Danish woman is now a model, personal trainer and fitness guru after a stunning 126-lb weight loss. Mathilde Broberg used two simple, yet effective tools to manage calorie counting and portion control. Broberg's had plastic surgery but only got a tummy tuck after doing the work to shed the obesity. Here's more on how the 20-year-old lost half her body weight.

Weight loss starts with mirror check

Mathilde Broberg was always obese, even as a child. She struggled with exercise and even amusement park rides were a problem. As a teenager, the Aarhus, Denmark native ballooned to 268 pounds which at 5'9' gave her a BMI (body mass index) of over 40.

Realization of her morbid obesity finally hit home when she began to really look at pictures and her figure in the mirror. One day, in 2012, Mathilde had enough. She ate her last piece of cake and revamped her diet. And just a few years later, she's transformed into personal trainer.

"Teaspoon diet" trumps obesity

The young woman had a lot of work to do in cleaning up those eating habits. She had to reel in the 3,500 calorie diet to a more workable 1,200 to 1,400 calories. Broberg uses a lot of food swaps and portion control to stem her junk food addiction. Instead of pasta salad bathed in dressing, Mathilde opts for fresh vegetables and Greek yogurt. Reality TV star and celebrity Mama June Shannon lost lots of weight with similar switches.

The reality TV star of "Here Comes Honey Boo Boo" had to quit the family's famous junk food diet. Broberg also tricked herself into thinking she was eating more by measuring portions with a teaspoon. Portions dropped from plate to palm-size.

Plastic surgery has its place

After tons of hard work and dieting, Mathilde got down to 138 pounds.

She models for a sportswear company. But despite being super-thin the young woman still had stubborn saggy skin. Even working out six days a week couldn't get loose skin toned up. So she had a tummy tuck, a cosmetic surgery procedure that akin to skin removal surgery. Patients on "My 600-lb Life" who have gastric bypass surgery and work very hard at weight loss may qualify to get this procedure. Chad Dean lost 370 pounds and has started a GoFundMe to have this done. But being a Danish citizen, the National Health will pay for Broberg's plastic surgery.
