For Amy Fritz, the breaking point came during a family vacation in late 2022. Nothing fit right, she avoided being in photos, and she didn't recognize herself in the few pictures she was in. "I was just honestly tired of walking around with the guilt and shame of knowing I was treating my body poorly and not doing anything about it," Amy shares in her post. At 230 pounds—her heaviest weight ever—she finally had her "enough is enough" moment and decided it was time for change.
Life Before the Change
Amy explains that weight wasn't always an issue for her. Growing up with an athletic build, she played competitive tennis through college without significant weight concerns. It wasn't until after having three babies in three years that her weight began to climb. "It was a culmination of things," Amy says. The exhaustion of having three young children, hormonal changes, grief from losing her father, and the isolation of the pandemic all contributed to her weight gain.

The Unhealthy Habits
During this challenging period, Amy's diet spiraled out of control. "I was eating terrible, terrible. I'm talking tons of soda, tons of sugary coffee just to caffeinate myself, all the sugars and everything," she admits. Fast food deliveries became a daily habit while living in Atlanta, and nightly ice cream was the norm. Combining poor nutrition with zero physical activity, Amy gained an additional 60 pounds over a couple of years.
Food Change 1: Shop the Perimeter
Instead of following a trendy diet plan, Amy focused on a simple strategy. "I didn't do low carb. I didn't cut anything out and tried to figure out what to add more of," she explains. Her first major change was shopping primarily from the perimeter of the grocery store. "For me, that was grocery shopping, the perimeter of the grocery store. So focusing on lean proteins, lots and lots of veggies, lots of fruit, lots of whole grains, dairy, and just prioritizing whole foods," Amy says. This single shift dramatically improved the quality of her diet.
Food Change 2: Track and Measure
Amy's second key change was tracking everything she ate. "I know that's not like the fun answer everybody wants to hear, but every single day I tracked my food in MyFitnessPal and I tracked every single thing," she shares. Amy used an online calculator to determine her personal calorie deficit and aimed for a moderate deficit of about one pound per week. When she did eat out, she tried to overestimate calories to stay on track with her goals.

Food Change 3: Calorie Deficit
The third critical change was consistently maintaining a calorie deficit while focusing on nutrition. "Going from eating 4,000-5,000 calories a day of ultra-processed food to then eating less than 2,000 calories a day with whole foods, my body just instantly, the pounds started coming off," Amy explains. She remained diligent with her approach about 80% of the time, allowing for occasional flexibility. This balance helped her sustain her efforts long-term.
Starting With Simple Walking
Intimidated by formal exercise after years of inactivity, Amy kept her initial fitness goals extremely manageable. "I kept it ultra simple," she says. With an accountability partner, she committed to walking on the treadmill for just 30 minutes, three times weekly. "I knew it was something that didn't overwhelm me. It got me back in the habit of just showing up to the gym and it got my body moving regularly for the first time in seven or eight years," Amy shares.
Building Consistency
Starting at a slow 2 mph pace with no incline, Amy gradually built her endurance. "It only took a couple of weeks to see that momentum start to build. I struggled those first couple of weeks...but three, four, six weeks in of walking three or four times a week, I was able to build up to three to four miles per hour," she explains. Eventually, Amy worked up to the "3-12-30" workout (3 mph at 12% incline for 30 minutes), which became her consistent routine.

The Early Results
Amy's body responded quickly to these lifestyle changes. After just one month, she had lost between 15-17 pounds. Though the pace eventually slowed to a more sustainable 5-6 pounds monthly, by May 2023—just six months into her journey—she had lost an impressive 60 pounds. "I looked at my MyFitnessPal and I was down like 15 or 17 pounds that first month. And then it slowly tapered off and I lost more of a realistic number of that five to six pounds a month," Amy recalls.
Discovering a New Passion
With spring weather arriving in Ohio and newfound energy from her weight loss, Amy decided to try outdoor running. What started as short, experimental jogs soon became a passion. "I was really enjoying the running, but I felt kind of lost. I felt like I didn't have a lot of purpose behind my running," Amy explains. To challenge herself, she signed up for a half marathon despite being terrified by the distance—a decision that would transform her journey.
From Weight Loss to Athletic Goals
Training for the half marathon shifted Amy's focus from losing weight to building strength and endurance. "I think I was around 155 by the time race day came around. So I was down a little bit more weight. I was basically back to my pre-baby weight," she says. When she completed the race in September 2023, Amy discovered a new motivation beyond weight loss. "I was hooked. I quickly realized how much I enjoyed having accountability, having something to train for and doing it scared," she shares.

The Marathon Challenge
No longer intimidated by the half marathon distance, Amy set her sights higher. In December 2023, almost a year into her health journey and nearly 80 pounds lighter, she signed up for a full marathon. "It all of a sudden didn't become about weight loss. I was just so fueled by training and knowing what I needed to prioritize," Amy explains. Her mindset had completely shifted from shrinking her body to strengthening it.
Reaching 100 Pounds Lost
By July 2024, approximately 18 months after starting her journey, Amy had achieved her remarkable 100-pound weight loss. "I can't even believe I'm saying that out loud. It's crazy to think. I'm so grateful for the journey, all the lessons I've learned," she shares. Even more impressive, Amy completed her first marathon in May 2024 with a time of 3:34—just four minutes shy of qualifying for the Boston Marathon.
Maintaining Success
Having maintained her 100-pound weight loss for about six months at the time of sharing her story, Amy now focuses on balance and strength. "I'm strength training more now than I ever have been, more like three to four days a week. And it's been cool to see progress. I'm fast, but I'm also getting stronger and can do some pull-ups now," she says proudly. Her motivation has evolved from weight loss to longevity and quality of life with her family.
Amy's Top Tips
Looking back on her transformation, Amy emphasizes three key lessons. First, start small with attainable goals. "I would have never run a 3:25 marathon if I hadn't started walking and committed to walking three days a week at the beginning of my journey," she points out. Second, find accountability—whether through a workout buddy, group fitness classes, or a coach. Finally, push yourself beyond your comfort zone. "Do it scared, find things that scare you and terrify you and tackle them one little bit at a time," Amy encourages. "You'll see growth happen."
