The 73-year-old woman who lost 55 pounds and became a viral sensation

STORY 1: The 73-year-old woman who lost 55 pounds and became a viral sensation

Think it's too late to change your body once you're over 50? Think again. In October, 73-year-old Joan MacDonald became an internet inspiration after showing off her incredible transformation.

"For many decades, I was more often overweight than at a healthy weight," MacDonald told The Daily Mail. "I was on medication for high blood pressure, high cholesterol, and acid reflux. My arthritis was acting up pretty bad."

Concerned about her health, MacDonald's daughter taught her mom how to use her iPhone to track her meals and exercise activity. That tool helped drive her to eat more protein and healthy fats, and go to the gym four or five days a week. And after making those major changes to her lifestyle, MacDonald lost 55 pounds in a year, gained plenty of muscle, and now helps others reach their fitness goals, no matter how old they are.

"For those who truly feel at a loss, I'd say change one thing with your food intake, one exercise to do, and each week add something new," she said. "Don't expect miracles right away, take it slow and steady but keep building."

STORY 2: The man who lost 150 pounds thanks to his college professor

When Joey Morganelli was 16 years old, he watched his father die of a heart attack right in front of him, only three years after losing his mother to cancer. Looking for a way to cope with such tragedy and loss, he turned to food. By the time he graduated high school, he weighed 400 pounds.

Luckily, Morganelli had people around him who cared about his wellbeing and were concerned by what they saw. In his freshman year of college, his microbiology professor pulled him aside to express concerns about his health, and asked him to watch the 2011 documentary Fat, Sick and Nearly Dead. The film had a major effect on Morganelli and slowly but surely, he replaced fast food with healthy, home-cooked meals. Eventually, he became more committed, going on a vegan diet, and by mid-2018, he had lost 150 pounds.

In January 2019, he wrote on Instagram that even though losing weight is hard, what's harder is facing yourself and dealing with the issues that drove you to overeat to begin with. "Give yourself a fair fight and take that blindfold off," he wrote. "It will propel you into places you never thought you could be."

STORY 3: The woman who became a fitness influencer after giving up alcohol

We all know alcohol contains plenty of calories, has little nutritional value, and can impede weight-loss and other lifestyle goals we set for ourselves. But a viral post by Instagram influencer

Jelly Devote really showed just how much curbing heavy alcohol consumption in favor of drinking more water can help you lose weight.

The photo on the left shows her at 21, during her college partying days, when she was drinking beer and cider with abandon. Now 27, Devote exercises, drinks in moderation, and feels like she's aging in reverse as a result.

"I'm a new person and I feel better both on the inside and about my outside," she wrote on Instagram in February.

STORY4: The bride who lost 135 pounds and wore her dream wedding dress

When Mary Jane O'Toole got engaged to her longtime boyfriend in 2016, she couldn't have been more excited about it. Weighing 281 pounds, however, made picking out a wedding dress somewhat of a disheartening process.

"I didn't want to buy a plus-size wedding dress, because they cost way more than straight sizes," O'Toole told People in April. "I felt like I was paying this fat tax—I didn't have the ability to buy affordable clothes because I was bigger."

When she and her husband-to-be saw photos of themselves from a trip to Disney World, they made the decision to lose weight together and began tracking their calories and meals with the the app LoseIt!

O'Toole lost 75 pounds in the first year, and another 25 once the couple began incorporating exercise into their routine. By the time the wedding rolled around earlier this year, she had lost a total of 135 pounds and was able to walk down the aisle in the dress of her dreams.
