Get Inspired by These Incredible Weight Loss Transformations

Roy told PEOPLE she “could easily down a pitcher of margaritas and 20 buffalo wings at happy hour,” and smoked a pack-and-a-half to two packs of cigarettes every day for 14 years.

While she quit smoking after getting pregnant with her first child in 2003, she kept her unhealthy eating habits until she began having health problems after having her third child.

She joined Weight Watchers and dropped from 248 lbs. to 122 lbs. by watching her portions.

What She Eats Now: Roy eats six small meals a day and still allows herself the occasional fast food burger — but will only eat half.

Her Workouts Now: She stays motivated to stay in shape by competing in bodybuilding competitions.

Her Best Weight Loss Tip: She uses a slow cooker to prepare healthy meals. “That makes my life so much easier. I’ll put some chicken in in the morning and it’s done for dinner.”

When Brianna Bernard got pregnant she "used it it as an excuse" to indulge in comfort foods.

"In reality, you’re only supposed to eat a couple hundred extra calories a day, but I was eating 1,000 extra,” Bernard, 32, tells PEOPLE for the 2018 “How We Lost 100 Lbs.” issue. “I assumed it would all fall off pretty easily after the baby was born.”

But after giving birth to her son, now 5, Bernard continued her poor eating habits and "didn't take the time for self care," she said.

Bernard eventually signed up with a personal trainer at the gym, Bodies by Burgoon, and started training two to three times a week in weight lifting, pylometrics, boxing and more. She also revamped her diet, ditching her processed, carb-heavy meals for lean proteins, healthy fats and vegetables.

A year later, she had dropped 100 lbs. and started powerlifting competitively. She even became a trainer at the gym that helped her lose weight.

"I feel like a completely different person, and I am in so many ways,” she says. “Not just physically — that’s obvious — but the way I feel in my mind. It’s hard to even look back. It feels like a lifetime ago. Now I feel like there’s nothing I can’t do. If I can lose 100 lbs., I can do anything.”

Rachel Saintfort had never let her weight be a source of stress.

"In high school I hit 200 lbs., but I was blessed to be a confident person," the Lakeland, Florida native tells PEOPLE for the 2018 “How We Lost 100 Lbs.” issue.

However, she continued to gradually gain weight and reached her highest, 291 lbs., after the birth of her daughter in 2007.

Saintfort decided to try dieting, but nothing stuck. Then, in January 2017, she got a wake up call. Her daughter, now 10 years old, said a classmate had called Saintfort "fat."

“She looked so sad, and she’s trying to act like it wasn’t a big deal. At that moment it hit me that she’s suffering, and she’s being picked on or laughed at because of my laziness or my unhealthy choices,” Saintfort says. “That definitely inspired me to get it together, because I didn’t want her to feel that way.”

The case manager, 32, decided to cut out fast food and soda and started doing daily 3-mile walks around the lake in her town.

She also started documenting her weight loss journey on her Instagram account, @Ms100Lbs, and set a goal to drop 100 lbs.

Less than 12 months later, she reached her goal. “I cried,” she says. “It was an amazing feeling."

At 280 lbs., Gwilym Pugh was overweight, out of shape and living a sendentary life.

After a "5 to 7 year" weight loss journey, which included a lot of "trial and error," Pugh, 33, lost 93 lbs. and found a new career.

Now, a top model and an ambassador for David Beckham's grooming brand House 99, Pugh, tells PEOPLE he focuses on a diet of micronutrients and good fats, and managable exercise.

"Due to injuries, I’ve struggled with high-intensity work, but I’ve found low-intensity cardio pre-breakfast has been great," says Pugh, who now sees an osteopath and a trainer, and aims for 20,000 steps per day.

As for life as an in-demand model and social media influencer: "This life is something I had never even thought to dream of," says the London-based Pugh. "Every aspect of my life has improved, from physical and mental health to personal and professional relationships."

A self-described "binge eater," Mariah Stolfi reached 150 lbs. by the 5th grade.

The Wisconsin native also struggled with health issues. In her early teens she was diagnosed with polycystic ovarian syndrome (PCOS) and sleep apnea. “It is extremely difficult to lose weight and maintain weight loss with PCOS,” says Stolfi, who hit her highest weight of 286 lbs. at age 18. “And the lack of good sleep caused me to be lethargic, which meant I didn’t have the energy to work out.”

In July 2017, Stolfi, 19, decided to undergo vertical sleeve gastrectomy surgery.

Now down 84 lbs. – she hopes to lose an additional 60-70 lbs. – she is sharing her journey on social media.

“Once I discovered the weight loss surgery Instagram community I knew I had to be a part of it,” says Stolfi, whose candid photos and videos have garnered her more than 14,000 followers on Instagram and YouTube combined.

As for her best advice to those struggling with their weight: “This journey is 80 percent mental and 20 percent physical. If you don’t fix your mindset you will not succeed on your weight loss journey.”

Growing up, Kathleen Golding had always been overweight. By 21, she had turned to food as a "coping mechanism" while wrestling with anxiety and depression.

"I was stuck in a constant cycle of daily binging," the New Bern, North Carolina resident, whose highest weight was 331 lbs., tells PEOPLE. "I was eating fast food for every meal and enormous quantities each time."

She finally decided to make a change and turned to gastric bypass surgery, which she underwent in June 2016.

“For some reason, weight loss surgery is seen as 'cheating' or being weak, but for me, I found strength in being able to say 'I can’t do this on my own. I want to be healthy, but I need help,'" says Golding, now 26.

After the surgery, the weight began to "melt off," says Golding, who eventually dropped 178 lbs. by making healthy dietary changes and exercising.

Now, Golding says she is finally at peace with her body. "I have some loose skin and it definitely has its imperfections, but I worked hard for this body," says Golding, who also documented her weight loss journey on Instagram. "I spent so much time hating it but I’ve realized that this is the only body I’ve got and I’m going to take care of it."

Growing up, Bonnie Wiles ate a lot of starchy foods, and by 18, she was over 200 lbs.

"I tried diets but kept gaining weight after getting married and having four children," Wiles, 58, tells PEOPLE in the 2018 Half Their Size issue. "It wasn't until my first grandson was born in 2011 that I committed to get healthy."

The Fayetteville, Arkansas, resident joined TOPS, a weight loss support group, and started using MyFitnessPal.

"It tells me if I'm overeating and helps keep track of how much I walk—usually 50 miles a week," says Wiles, now 148 lbs.

And she is loving her new lifestyle.

"When I was heavy, I had to ask for a seatbelt extender on a plane. Now I can't wait to go with my family to Hawaii, where I can show off my favorite body part—my arms."

After a family hiking excursion proved too taxing for his 290-lb. frame, Jeremiah Peterson decided to change his lifestyle.

"I remember being bent over heaving just trying to catch my breath," the Missoula, Montana-resident tells PEOPLE. "When I looked up, I saw my wife and three kids [10, 8 and 7] easily hiking, talking and laughing with each other — without me. It was a hard-hitting moment."

He entered a transformation challenge for motivation. Then, switched over to a keto-based diet consisting of healthy fats, lean protein and green vegetables, started taking twice-daily hour-long hikes, and lifting weights.

Peterson, now 198 lbs., ended up dropping 82 lbs. during the 150-day transformation contest, called the 1st Phorm Transphormation Challenge — and he won the $50,000 grand prize.

He says: "I feel like I have drive and ambition like I have never had before in my life — and I’m almost 40!"

Rachow, 30, remembers the exact day she decided it was time for a change.

“I had been living a life of obesity for a few years and was exhausted both physically and mentally,” the physical therapist tells PEOPLE. “I felt like I had gained so much weight that I would never get it back off. I still remember the day that the switch flipped for me — July 19, 2014 — and I decided I was done living like this.”

The Medina, Ohio, resident says until that point she was drinking five or more cans of soda a day, eating large quantities of food and stopping at the drive-thru daily.

“Exercise was out of the question as I could barely walk up the stairs to my apartment,” she says.

Spurred into action, Rachow says she started small, first cutting out soda and only eating food she cooked at home.

“The weight starting coming off,” she says. “I remember I lost 9 lbs. my first week. After I had lost 100 lbs., I started trying more adventurous exercise. I became fascinated by fitness and seeing what new things I could accomplish with my body. I do things that I never dreamed were possible like running races, lifting heavy weights, and completing a sprint triathlon.”

After Bauler's father-in-law went on life support following a heart attack in 2010, the Madison, Wisc., resident said he knew he needed to change his own ways.

“At this time I was 28, had two young boys, Eli (2) and Carson (6 months),” he says. “I recall all of the family standing around crying and sad. This was the trigger for me as I knew if I didn’t get my life together soon, I would be the next person in that hospital bed.”

A few weeks after his father-in-law was admitted to the hospital, Bauler, who weighed 450 lbs. at his heaviest, signed up at a local gym. He first focused on exercising and eventually made changes to his diet, sticking to 1,500 calories a day and smaller portion sizes for one year.

Now the 35-year-old runs everyday and has completed endurance competitions like Ironman and Ragnar.

“I lost most of my weight (200 lbs.) in about 18 months so I have had to stay busy to keep it off,” he says. “I am extremely competitive and have an amazing network of friends and the From Fat To Finish Line (FFTFL) community. I like to join training groups and training clubs because of the friendships and accountability it creates. It would be easy for me to blow off a 10-mile run at 5:30 on a Friday morning, but I know I have two friends meeting me, who I would never let down.”

After reaching her highest weight of 350 lbs. at 26 years old, Boston resident Katia Powell realized her own health didn’t reflect her dreams of becoming a medical doctor.

Powell was overweight as a child, eating a diet full of processed foods and little water and vegetables. In college, Powell says she dramatically gained more weight. “I walked into my apartment, stared at my reflection in the mirror and asked, ‘Who is that?’ It was a defining moment for me,” says Powell, 38, who is now a holistic health practitioner and fitness trainer who has founded the company Black Girls Nutrition.

Powell joined her local YMCA, gradually increasing her workouts until she was going 4 to 5 days a week for 60 to 90 minutes. She also changed her eating habits, replacing sugary sweets with fresh fruit and vegetables. Within the first six months she lost 100 lbs., and has since lost another 70 lbs.

Powell, who has kept the weight off for 12 years, says she now loves cycling, dance and yoga, and “if I am unable to attend the gym, I run or take a walk outside, or workout at home and do a high intensity interval training. My workout routine also includes meditation,” she says.

Cloutier, 36, always felt like an outsider growing up. She weighed 220 lbs. in high school, and never enjoyed shopping or playing sports with her friends.

“I cannot remember a time when I didn’t feel like I was the biggest girl in the group, and I hated it,” Cloutier tells PEOPLE for the 2018 Half Their Size issue. “I was always the odd one out.”

After her first pregnancy with her daughter in 2003, Cloutier hit 301 lbs., and was ready for a change. "I didn't want to die," she says. "I wanted to watcher grow up and give her healthy habits." By working out with a trainer and choosing healthier meals, she successfully lost 151 lbs., and maintained a healthy weight through her second pregnancy in 2008.

As she worked to get back into a postpartum fitness routine, Cloutier discovered Zumba, and fell in love with group fitness classes. Three weeks after her first class, she became a certified trainer, and started teaching classes. By 2013, the demand had gotten so large that she opened her own fitness studio, and now runs it along with her full-time job.

Cloutier is now getting ready for another big change — her third child.

“I’d be lying if I said I wasn’t concerned about gaining the weight back, because gaining weight is still scary, and having to purposely do it is scary,” she says. “But knowing the difference between a healthy pregnancy and an unhealthy pregnancy is huge.”

Between her severe anxiety, depression and her weight — 280 lbs. at her heaviest — Bolden, 31, felt "ruined," mentally.

“I hated everything about myself, and that’s just a tough situation to be in," she tells PEOPLE for the 2018 Half Their Size issue.

Then at age 26, Bolden was diagnosed with polycystic ovary syndrome, and learned she would have trouble conceiving a child. And just a few years later, in Feb. 2013, she went partially blind in one eye, and found out she had pre-multiple sclerosis.

"It lit a fire in me," she says. “I just realized that I was just existing and wasting my life away, and it was time to do something and start living.”

Bolden started tracking everything she ate on MyFitnessPal, and took up swimming, hiking and weightlifting. After three and a half years, she lost 150 lbs., and had her daughter. She also started a fitness blog and Instagram, and even won a bodybuilding competition.

“I look back on all the stuff I did and say, ‘Did I really do that?’ ” she admits. “As someone with such severe anxiety, to go out and do that, I know that I’ve progressed, not only physically but mentally as well.”

Weighing in at 639 lbs., Gause was terrified of dying.

“I’m not ready to leave this planet,” he said during an appearance on The Doctors in Oct. 2016. “And I know the way I am now, I probably don’t have much time.”

Gause was ready to make a change, and he immediately joined Live in Fitness, a residential weight loss community. There, he completely revamped his diet plan to focus on lean proteins and vegetables, and started exercising. In just over a year, he's lost 303 lbs.

“Since losing this weight, I’m like a new person,” Gause said during a return visit to The Doctors. “Every day I wake up and I can move.”

Jason Cohen always struggled with his weight. At his highest, he hit nearly 300 lbs.

"My entire life I always thought I would be big," said Cohen, 33, who ran, cycled, forged a weight-loss competition with a friend, and adopted a plant-based diet to help him slim down.

A big motivator to help him acheive and maintain his 125 lbs. weight loss is a private Facebook support group dubbed the "Missing Chins Run Club."

“When I see other members post a 7-mile run in the Facebook group, I don’t have any excuses,” said the Lafayette, Louisana resident. "Time to lace up and get out there."

Although she was happy and confident in her body, Jovana Borojevic was shocked when she finally stepped on a scale.

“I never in my life imagined that I would see a ‘3’ in front of my weight,” Borojevic, who hit 304 lbs. and had developed fatty liver disease from her fast food-heavy diet, all while dealing with Polycystic ovary syndrome, or PCOS, tells PEOPLE. “From this day forward, something clicked in me and I changed my life around cold turkey.”

The digital marketing strategist, now 24, immediately cut out starchy carbs, refined foods, sugar and most packaged food. In a month she dropped almost 20 lbs., and started hitting the gym four to five times a week for weight training and cardio workouts.

Now a year and a half into her weight loss journey, Borojevic is down to 165 lbs., with a goal weight of about 150 lbs.

“It is SO IMPORTANT to focus on non-scale victories like how your clothes fit, how you feel, how many health issues you’ve reversed and saved yourself from and how happy you are!” she says.

Allie Ruby was determined to lose weight — and get her long-desired six-pack — after her poor college eating habits left her at 225 lbs. But 98 lbs. later, she still wasn't happy.

“I always thought that I would love to have a six-pack, and when I got there last year, it wasn’t all the fireworks I thought it would be. I thought that would be a huge high, but it wasn’t,” Ruby, 28, tells PEOPLE.

She started weightlifting, which kept her in amazing shape but pushed her weight up again, this time with muscle instead of fat. Seeing the numbers creep back up the scale caused self-doubt.

“If you have ever lost a substantial amount of weight then gained some back you probably have an idea of that devastating feeling of going backwards — I think those feelings were more painful at that time than when I was overweight,” Ruby wrote on Instagram, adding that it’s been helpful to practice mindfulness at this point in her journey. “I had to remember that a transformation is far deeper than physical.”

Now she's switched from weightlifting to powerlifting, which requires extra weight, and is much happier.

“It’s so different, because no one cares about your image. It’s all about how strong you are,” Ruby tells PEOPLE. “I love it.”

Jobity was always fit growing up, but when she was mistreated in a relationship, she turned to food to cope.

“I stopped caring for myself as much as I should have,” the Toronto-based finance project analyst, 36, told PEOPLE. “I was depressed. I just kind of tuned out of the world, and food became my everything."

By 2015, Jobity had hit her highest weight of 260 lbs. and started feeling excruciating stomach pain.

“When I went to my doctor they explained I had a stomach ulcer, and that all those years of soda had damaged my stomach,” she said.

Jobity decided to get healthy — mentally and physically. She started taking boot camp classes and sought counseling to deal with her emotional issues.

What She Eats Now: Jobity cut out fried food and soda and eats a diet focused on fruits, vegetables and lean protein. “I love salad and chicken,” she said. “Salad and chicken are my everything!”

Her Workouts Now: Jobity works out six days a week.

Her Best Weight Loss Tip: “You have to fix what’s going on inside before you can fix the outside. The mind is a powerful thing through the weight loss journey, more than anything else. A lot of weight loss is mental.”

Teeter had struggled with her weight her whole life, and found herself weighing over 300 lbs. by the time she was 26. She ignored her mounting health problems — painful water retention in both her knees, eczema breakouts and nightly bouts of acid reflux — until a doctor's visit that inspired her to make a change.

She began keeping a food diary and joined a gym. Teeter, now 34, soon was physically capable of doing things she never thought possible, like running multiple half and full marathons, climbing a mountain and even sky diving. But it wasn't until she ran a naked 5k that she learned to truly embrace her body.

“It’s not often in your life that large groups of people openly accept you and cheer for you despite what your body looks like or your physical ability,” she told PEOPLE.

What She Eats Now: Teeter made healthy swaps for junk food and keeps track of her macronutrient intake.

The 5’7″ self-employed mom-of-three from Rapid City, South Dakota, 35, was already over 200 lbs. when she started having children, but her pregnancy weight brought her up to 304 lbs. After having her second child, she knew she wanted to make a change.

“I wanted to be an active mother and be able to play with my kids," she told PEOPLE. "I also wanted to live my life, not just exist. I wanted to experience new things and felt my size was holding me back.”

For years, Helen Costa-Giles had no real motivation to lose some of her 220-lb. body weight, despite concerns from her doctor. But in 2014, her yearly checkup took a somber turn when the mom of two learned that she was on track to develop chronic health problems because of her size.

“My numbers were really off the charts and it scared the life out of me,” Costa-Giles, 38, tells PEOPLE. “That was exactly my turning point.”

Determined, she immediately threw out all processed and preservative-filled foods, and started eating a clean diet. In just six months, with no exercise, she dropped close to 90 lbs. Costa-Giles then added weightlifting to her days, and fell in love.

“My body reacted very quickly to weightlifting, and I started to lean out,” she says. “The scale wasn’t making huge differences, but the inches were changing. I kind of got obsessed because for the first time in my life, my body was actually doing what I asked it to do.”

Costa-Giles now runs free exercise classes in her hometown of San Antonio at 4 a.m., four days a week, all while maintaining her full-time job in the automotive industry.

“I have two kids and a full-time job,” she says. “I know many people don’t start their fitness journeys because they have too many excuses. I like to share my story because it’s so relatable.”

Dustin LaJaunie has come along way from the 425 lbs. he weighed five years ago.

Now, he's lost 150 lbs. and counting with the help of his younger brother Josh LaJaunie, who started the private Facebook support group called "Missing Chins Run Club."

The group is a safe place for people to share their stories and struggles and to motivate one another to lose the weight.

Eating plan-based and running alongside his brother, Dustin compares the Missing Chins to the trips he and his brother used to take when going hunting. “But instead of gathering to go take life, we’re coming together to gain life."

The Gloucester, U.K.-based nursery manager, 42, was a longtime emotional eater who found herself reaching a high weight of 223 lbs. at only 5'3″.

“My blood pressure was through the roof,” she told PEOPLE. “The doctor said that I was a heart attack or stroke waiting to happen. My mum had a stroke very young, and it scared us as a family. I didn’t want to put my family through the same thing, so knew I had to do something.”

Byrne credits doing at-home Jillian Michaels workouts and decreasing her portion sizes with helping her drop 70 lbs. She also says having a partner with Parkinson's disease inspired her to get her health on track.

McGee began gaining weight when she got into an unhealthy relationship and stopped spending time with friends or going to the gym. After getting out of the relationship, she decided it was time to make a change — especially since she worked in the health profession.

“As a nurse, I wanted to be the healthiest version of myself that I could be,” she told PEOPLE. “I didn’t want to be a walking contradiction to my patients, promoting healthy living but not being healthy myself.”

The Middlesex, England-based nurse, 26, decided to join Slimming World to take control of her health.

Her Best Weight Loss Tip: Don't be afraid to make a change. "There is nothing to lose and so much life to gain.”

Jenkins, 22, says that overeating was just part of her daily routine. “Every day I would come home from school, watch TV with my sisters and eat a whole package of snack cakes,” she told PEOPLE. After dinner, she’d continue to snack on packaged foods like ramen with cheese and more snack cakes. But when she got to college, everything changed.

“The turning point for me was meeting so many new people and realizing ‘Wow, I’m really actually very uncomfortable,’ ” the Knoxville, Tennessee, resident says.

The Delaware-based paralegal had reached 280 lbs. by the time she was 20, but it wasn't until her father had heart surgery when she was 25 that she decided to take charge of her health.

"Learning that health issues ran in my family scared me," Battle, now 30, told PEOPLE. "I knew that doing some form of movement in my living room was better than nothing, so I went to my local superstore and bought workout DVDs."

When one of her sons told her she looked "really fat," she decided she needed to start making health a priority. On nights she has a sitter, McDonald hits the gym, and on other nights she does workouts at home once her kids are asleep.

In December 2015, Cines read about a Bodybuilding.com challenge and decided to take part in it. She started working out three times a day and saw real changes in her body for the first time.

"A lot of people think getting in shape is getting a six-pack, but that’s not what it’s about,” she says. “The best part of getting in shape is the self-confidence and my overall outlook on life."

Cockrell, 30, had struggled with her weight since high school and "used food as an emotional pick-me-up" through the years as she dealt with her parents' divorce and problems with her own marriage.

Osuna — who weighed 182 lbs. at her highest and now weighs 180 lbs. — weight lifts four days a week and only does cardio twice a week.

Powers began logging her food intake using the Lose It! app, and says it helped keep her accountable. Now she eats a lot of lean meats and vegetables, and works out three times a week.

“I like that my kids are used to hearing ‘yes’ a lot more,” said Powers. “Before, I could never take them to the park and run around with them and be the mom that I wanted to be. Now there’s no limitations.”

Pullen, 48, first put on weight due to medical complications stemming from her first pregnancy, but it wasn't until a boy at a local pool called her a hippopotamus in front of her whole family that she felt inspired to lose weight.

“It was in front of my children,” she told PEOPLE. “It was horrible. I went home and cried a lot, but I realized kids learn from what you do, not what you say — and that’s what kept me pushing.”

Pullen decided to try bodybuilding, and turned to Arnold Schwarzenegger for her inspiration.

Now she works out six days a week. “I’ll be 49 this year, and I feel like I look a lot younger. It’s the secret of youth!”

To lose weight and get healthy, Hug, now 34, began tracking her food intake and became more aware of how much sugar, fat and carbs she was consuming. But the biggest change in her lifestyle came from discovering her love of fitness.

“[When I was heavier] I didn’t find any joy in it, it wasn’t fun for me,” she told PEOPLE.

Now she does cardio five days a week and strength training two to three days a week, and even teaches fitness classes as a certified personal trainer.
