FACT CHECKED BY Christopher Roback

If you have a lot of weight to lose, it can seem hopeless and impossible. However, Samantha Costa, a 23-year-old influencer, lost a whopping 60 pounds in 3 months. In a viral YouTube video, she explains exactly how she did it, and a lot of it had to do with shifting her perspective and overall approach to weight loss. 

Losing 60 Pounds in 6 Months with PCOS

She starts with her backstory: In 2018 she was diagnosed with PCOS (polycystic ovary syndrome), which resulted in weight gain. "I fluctuate weight a lot and it also affects my periods. With that being said, because I was diagnosed with PCOS, I put on a lot of weight very fast, and it wasn't a type of weight that was healthy," she said. Costa, who is five-foot-one, topped the scale at around 200 pounds. "Being in a place where I knew I wasn't healthy was really scaring me." At the time she was able to drop 50 to 60 pounds in "five to six months" by going to Orangetherory and eating right.  "I think I weighed around 196 pounds and I got down to around 135," she specified.

The Power of Whole Grains


Her main dietary change at the time involved swapping out white carbs with whole grain and whole wheat. "I literally had grilled chicken, pasta, grated cheese, and tomato sauce every single day because that's what made me happy," she said.  After graduating from college in May 2022, "and I honestly was a very steady weight of around probably 129 pounds to  140 throughout all of my senior year of college," she felt like she was at a healthy weight for herself around 135 pounds. She spent the summer lifeguarding. "I was having a really fun time, and honestly everything was going very well," she continued. 

A Stressful Job Ruined Her Health and Happiness

However, in August she started her "big job at a big four company" and it was "the downfall of everything," she claims. "I'm not going to talk too much about it, but the stress of that job, which I am no longer working in, was very, very hard for me." She stopped working out and spent most of her free time isolating. Over a period of about 7 months she probably gained 60 to 70 pounds, and was "very, very sad," she says.  "I wasn't happy with how I looked and I was having a hard time with it, but it was more that I knew I wasn't healthy and I knew I needed to get healthy because of this. I would always tell myself, 'You know what? You did it once. You can definitely do it again.'"

From 10,000 Steps to 500

She couldn't motivate herself to go to fitness studio again, "something that I used to love going to do," she says. While she used to walk 10,000 steps a day, she "was lucky if I hit probably 500 steps a day because I was always at my computer, always doing something for work, and there was really just no time for me to do it." 

She Lost 10 Pounds in a Week and Kept Going


Every day she looked in the mirror and told herself "in three months from now, you will look so much better. You'll feel so much better, which is the most important, and you will want to do things because you started." Eventually she started seeing progress, claiming that she lost 10 pounds in one week, which she knew was water weight. Within a few weeks she noticed a "little bit of a difference" and once she started to see that difference, "it was a lot easier to believe in myself and notice that there was real progress happening and that there was change happening, which allowed me to keep going within my journey."

The Secrets to Her Success


She revealed that she did keto, which is "very hard to sustain," she admits. "It was very hard for me to eat a certain amount of carbs every single day, and it was very hard for me to cut out sugar. I'm someone who loves sugar, but I knew that in order to be in a healthy place again, and in order to get to my goal in the most efficient way, especially with summer coming up, I needed to do something that would really change and really allow my body to adapt."  She also emphasizes the importance of protein. "Eating carbs is something that obviously we all need. I am not saying don't eat carbs. Please eat your macros. Please eat carbs. Please allow yourself to have the energy that you need. I'm just saying what I did was I lowered the amount of carbs that I ate, but I was still eating enough to feel energized to be able to go to the gym and to give my body what it needs."

She Increased Intake of Proteins and Exercised


Amping up your protein intake may help you lose weight. According to clinical trials, consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets. She also went back to fitness studio four to five times a week, starting with gentle workouts and working her way up to more intense ones. She also recommends taking rest days. 

Stay Motivated and Positive on Your Journey


"In the beginning, you're probably going to feel like you can't do it and it's probably going to feel impossible, and if you are someone who doesn't feel like that, I give you so much credit because I've been there so many times and I felt like it was impossible every single time," she adds. "The number one thing I want to tell you is to prove yourself wrong. Prove every single person that may have doubted you wrong. The only thing that matters is that you believe in yourself. The only thing that matters is that you have the mindset that will allow you to feel better, and every single time you question yourself, make one of those videos, take progress pictures, tell yourself that you are so much better than you were even one day ago, and if you are really having trouble starting, just try for one day."
