This 25-year-old dropped 80 lbs. and still ate 5 times a day

This 25-year-old dropped 80 lbs. and still ate 5 times a day Mara Smith says she was let go from the Navy because of her weight. She decided something had to change. Keep reading to learn how Mara finally was able to lose 80 pounds in just under two years. Mara's history with food and weight Mara had always struggled with her weight, and when she joined the military, it continued to be an endless battle. She barely made it through boot camp, and said, "I was one pound away from being out of standards." Living with that amount of stress caused her to gain over 70 pounds in four years.

At nearly 200 lbs., California native Jennifer Riveira says she was unhappy, unhealthy and unable to be.

“My marriage was at an all-time low,” the mom of two, 45, tells PEOPLE. “My husband and I weren’t getting along because frankly, I made it really hard to love me because I stopped loving myself.”

When her now 13-year-old son Brandon asked her to play outside or ride bikes, Riveira had to say no because she simply didn’t have the energy. “I was overweight and I was tired,” she recalls. “My son said I yelled from the time I got up in the morning until the time I went to bed at night.”

Riveira made excuses for her poor health and weight gain, eventually scheduling a doctor’s appointment in March 2017 because she was convinced something was medically wrong with her. Expecting a thyroid-related diagnosis, what she got instead was a major wake up call: “My doctor said, ‘Your tests all came back fine. But what we really need to look at is what are you eating.’ “

Not ready to confront the root of the problem, Riveira continued telling herself that her busy schedule, which consisted of shuffling Brandon to and from sports practices and tournaments, didn’t allow for healthy eating.

“In reality, I had just given up on myself,” she tells PEOPLE. “Everybody became more important than I did and fast-food became my way of life. It was fast. It was easy.”

Then, about two years ago, Riveira was scrolling through social media when a friend’s weight loss post jumped out at her.

“She had posted that she was able to be on the floor and play with her son,” Riveira says. “I remember thinking, ‘Gosh, I just want that.’ I reached out to her and asked her what she was doing.”

My body craves those minerals and vitamins the shakes give me.”

Making One Simple Diet Rule Helped This Guy Lose More Than 100 Pounds

Making One Simple Diet Rule Helped This Guy Lose More Than 100 Pounds Beyond just wanting to get healthier, Matthew Galit long had another goal in mind: He wanted to become a police officer. As a bigger guy, however, he'd always put that dream on the back burner, knowing he’d never pass the physical. To put himself on the right path, Galit started with his diet, creating a straightforward rule he would refuse to break: “I told myself I wouldn't eat anywhere that had a drive-thru,” he says. Immediately, this rule forced Galit into re-thinking every meal: He'd even check menu options before dining out with friends.

“The challenge itself is to feel better about yourself, to be the best version of you, whoever you are,” Riveira says.

One of the most unforgettable moments in Riveira’s journey came a few months ago when she asked Brandon to describe her in three words as part of a personal development exercise.

“He said: dedicated, loving, and inspiring,” she recalls. “It’s about so much more than just the weight loss — I have a happy healthy 13-year-old who now sees what good nutrition can do for you. That means the world to me.”
