The 'Glucose Goddess' says 3 small diet tweaks revitalized her mood and energy. Here's how to use them wisely.

"It started with a donut. One morning in her 20s, Jessie Inchauspé says, she grabbed her usual sugary breakfast on her way to work in Silicon Valley - and noticed something strange. Her new fitness tracker showed her blood sugar spiking, then crashing. The pattern mirrored her bouts of brain fog, anxiety, and exhaustion, she said. "It might seem obvious today that what we eat impacts our mental health, but back then, for me, I hadn't connected the dots," Inchauspé told Business Insider."

"That moment sent Inchauspé - now known to millions online as the Glucose Goddess - down a rabbit hole. She joined a pilot study using a continuous glucose monitor (or, CGM), devices that were typically reserved for people with diabetes, to see how food affected the day-to-day mood and energy of otherwise healthy people. Years later, shehas built a massive brand around the insights she took away from that turning point. More than 5 million people follow her on Instagram."

"CGMs have since exploded in popularity among athletes, CEOs, and ordinary people trying to lose weight or to feel less sluggish. Some are now sold without a prescription, such as the Stelo, a device from Dexcom that Inchauspé has partnered with. The science behind blood-sugar \"optimization\" is evolving. It's normal to have occasional dips and spikes in blood sugar, and researchers have not yet determined what the optimal range might be for people without diabetes. Dietitians caution that self-tracking can sometimes lead to overanalyzing normal"

Jessie Inchauspé began using a continuous glucose monitor after a sugary breakfast revealed blood-sugar spikes and crashes that aligned with episodes of brain fog, anxiety, and exhaustion. She joined a pilot study linking food choices to daily mood, energy, and metabolism and then grew a large online following sharing practical "glucose hacks," including starting the day with protein to stabilize blood sugar. Continuous glucose monitors have become popular beyond diabetes, with some devices now sold without prescriptions. Scientific understanding of optimal glucose ranges for non-diabetics remains unsettled, and dietitians warn self-tracking can prompt overanalysis of normal fluctuations.
