People love a good "reveal," don't they? But if you’re looking for a dramatic "I lost 100 pounds by drinking this magic tea" headline about Sierra Schultzzie, you're looking at the wrong person. Honestly, the internet has been buzzing about Sierra Schultzzie weight loss for months now, sparked mostly by a few TikToks where she looks noticeably different than she did three years ago.
She's thinner. That's the observation.
But for Sierra, the story isn't about a diet. It's about a total shift in how she treats her body after years of fighting it. If you've followed her for a decade, you know she’s the queen of the midsize movement. She built an entire career on the idea that you don’t have to be a size 2 to be happy, fashionable, or worthy. So when her body started changing, some fans felt… well, betrayed. It’s complicated.
The 30-Pound Shift and the PCOS Puzzle
Let’s get the numbers out of the way. Reports and fan tallies suggest Sierra has lost around 30 pounds over the last year or so. It wasn't overnight. It was slow.
For Sierra, weight isn't just about calories in versus calories out. She has been incredibly open about her struggle with Polycystic Ovary Syndrome (PCOS). If you know anything about PCOS, you know it’s basically like playing a video game where the controls are inverted and the difficulty is set to "impossible." It affects your hormones, your insulin, and—most frustratingly—how your body stores fat.
For years, Sierra talked about how PCOS made weight loss feel like an uphill battle. But something changed in her approach. Instead of trying to "beat" her body into submission with restrictive diets that never worked, she started focusing on blood sugar stability and joyful movement.
She didn't wake up one day and decide to be "skinny." She woke up and decided to feel better.

Why "Joyful Movement" Actually Worked
Sierra’s viral "30 Days of Exercise" video wasn't about a gym grind. It was about closing her Apple Watch rings in a way that didn't make her miserable. Some days she just walked on the treadmill. Other days it was a dance party in her living room.
The radical part? She stopped punishing herself.
Most people fail at weight loss because they treat exercise like a jail sentence. Sierra treated it like a hobby. When you have PCOS, high-stress, high-intensity workouts can actually backfire by spiking your cortisol. By choosing low-impact, consistent movement, she actually worked with her hormones for the first time. It turns out, consistency beats intensity every single time.
The Controversy: Did She Sell Out Body Positivity?
This is where things get messy.
There’s a segment of the internet that thinks if a body-positive influencer loses weight, they’re "fatphobic." It’s a weird, parasocial pressure. Sierra has had to navigate the "sell-out" allegations while just trying to live her life.
She addressed this head-on, basically saying: "I can believe in body neutrality and still want to feel stronger."

It’s a nuanced take that a lot of people miss. Body positivity isn't about staying the same size forever; it's about loving yourself through the changes. Whether she’s a size 16 or a size 12, her message has always been about confidence. Ironically, some of the harshest comments came from the very community she helped build.
The Post-Baby Reality
We also have to talk about the "mom" factor. Sierra’s body went through the ringer with pregnancy and the postpartum period. Anyone who’s had a kid knows your body isn't yours for a while.
As she moved out of the toddler phase with her daughter, she gained a little more "Sierra time." That extra 20 minutes a day to meal prep or go for a walk adds up over a year. It wasn't a "bounce back" (she hates that term). It was a slow reclamation of her own physical space.
What Her "Diet" Actually Looks Like
Sierra doesn't do "diets." She’s talked about how restrictive eating triggered her in the past.
Instead, her approach in 2025 and 2026 has been about:
- Prioritizing Protein: Helping with PCOS-related hunger and muscle retention.
- Home Cooking: Not because "outside food is evil," but because it's easier to control ingredients and, let's be real, it's cheaper.
- Reducing Processed Sugar: Again, this is a PCOS management thing, not a "skinny" thing.
She still eats the cake. She still goes to Disneyland and eats the churros. She just doesn't do it every single day. It’s balance, which is way less "clickable" than a crash diet but way more sustainable.

The "End" of the Main Channel
In early 2025, Sierra made a huge announcement: she was stepping away from her main YouTube channel. Ten years of hauls and "brutally honest" reviews took a toll.
This move was probably the biggest contributor to her health journey. When you aren't under the microscope of 1.4 million subscribers every week, your stress levels drop. Lower stress = lower cortisol = easier weight management.
She shifted her focus to her vlog channel (Sierra & Stephen IRL) and her podcast. By removing the pressure to "perform" her body for the internet, she ironically found it easier to take care of that body.
Actionable Takeaways from Sierra’s Journey
If you’re looking at Sierra and wondering how to apply her "vibe" to your own life, here’s the actual blueprint:
- Stop the "Before and After" Obsession: Sierra didn't do a big reveal. She just lived. Focus on how you feel on Tuesday morning, not what the scale says on Friday.
- Manage the Medical Stuff First: If you have PCOS or another hormonal issue, "eating less" might not be the answer. Talk to a professional about insulin resistance and inflammation.
- Find "Joyful Movement": If you hate the gym, don't go. Walk, dance, swim, or chase your kids. If it feels like a chore, you won't do it for ten years.
- Accept the Ebb and Flow: Your body will change. You will gain weight. You will lose weight. Neither of those things changes your value as a human being.
Sierra Schultzzie hasn't "fixed" herself because she wasn't broken to begin with. She’s just a woman in her late 20s navigating health, motherhood, and a very public career. Her weight loss is a byproduct of a lifestyle shift, not the goal itself.
Focus on the habits, and the results usually take care of themselves.
