1 YEAR Of Weight Gain (With Results!)
Stephanie Buttermore spent a year eating whatever her body demanded — and came out of it 35 pounds heavier by design.
In May 2019, fitness influencer and cancer research PhD Stephanie Buttermore stopped counting calories, stopped tracking macros, and gave herself permission to eat until she was full every single day. A year later, in her video “How 1 YEAR Of Weight Gain Changed My Life Forever (All In Results!),” she laid out exactly what happened to her body, her appetite, and her cycle after twelve months of deliberately abandoning the lean, competition-ready physique she’d spent years chasing.
- Buttermore launched her “All In” protocol in May 2019 to combat “extreme hunger” — a “bottomless pit” feeling she said left her unable to feel full — and to restore a menstrual cycle lost to chronic amenorrhea.
- At the outset, she was eating upwards of 5,000 calories a day to satisfy her body’s cravings; by the one-year mark in May 2020, she had gained roughly 35 pounds total.
- Her cycle returned, her hunger cues eventually normalized, and she reported major gains in energy, strength, and mental health, even as she lost her six-pack and muscle definition.
The Bottomless Pit Problem
Buttermore’s decision to go “All In” didn’t come from vanity in reverse. It came from years of maintaining an extremely lean bodybuilding physique that had quietly broken her metabolism and hormonal function. The amenorrhea — the complete loss of her period — was the clinical red flag; the “extreme hunger” was the body’s own countermeasure, a relentless drive to eat that she said no amount of willpower could override. She described it as never being able to feel satisfied, no matter how much food she consumed.
Eating Without Rules
The “All In” protocol itself was deceptively simple: no calorie counting, no macro tracking, unconditional permission to eat to full satiety every day, for as long as it took. In the early months that meant consuming more than 5,000 calories daily just to keep pace with what her body was demanding. It’s a philosophy that sits at the opposite end of the spectrum from the tracking-and-deficit approach covered in body recomposition content aimed at building muscle while losing fat — Buttermore’s entire point was to stop optimizing and just let her physiology recalibrate.
The One-Year Numbers
By the time she filmed her one-year update in May 2020, Buttermore reported a total weight gain of approximately 35 pounds since starting the experiment. More importantly to her, the ravenous hunger that had defined the first stretch of the journey eventually plateaued — her appetite settled into something resembling normal for the first time in years, and her menstrual cycle came back.
The goal was to “unhook aesthetics from health.”
Unhooking Aesthetics From Health
Buttermore was explicit that the six-pack and the muscle striations were never coming back cheaply — losing that visible definition was the trade-off, not a side effect she was fighting. What she got in return, by her own account, was more strength in the gym, more consistent energy throughout the day, and a mental state no longer dictated by hunger she couldn’t control. Her partner, fellow fitness influencer Jeff Nippard, said the shift improved her overall quality of life and their relationship, pointing to the social and physical constraints her old restrictive routine had placed on both of them.
Nippard’s read on it wasn’t about physique at all — it was about being able to go out to dinner, travel, and live without the rigid structure that extreme leanness had demanded for years. That’s the note the year-long update closes on: not a six-pack lost, but a life that got easier to live day to day.
