Sharam Fouladgar-Mercer turned his lifelong battle with weight into a mission to empower others through personal metabolic insights.[1][2]
Athlete’s Frustration Fuels Breakthrough Idea
Sharam Fouladgar-Mercer excelled as a Division I hockey player at Princeton University, even fielding offers to play in the NHL. Yet, he watched teammates consume 5,000 calories daily without gaining weight while he struggled on far less. Years of yo-yo dieting left him exhausted and searching for answers.[1]
In 2018, a diabetic friend’s continuous glucose monitor (CGM) changed everything. The device revealed real-time responses to food and activity, prompting Fouladgar-Mercer to question why such tools waited for chronic conditions. He tested it himself, shed 40 pounds, and regained the weight deliberately to validate results despite skepticism from medical experts.[1][3]
This personal experiment laid the foundation for Signos, his company that pairs CGMs with artificial intelligence for weight management.
Signos Secures FDA Milestone for Non-Diabetics
Signos became the first FDA-cleared glucose monitoring platform specifically for weight management in August 2025. The approval followed one of the largest clinical studies on metabolism, involving 35,000 participants that proved efficacy across diverse bodies.[1][4]
The system targets the 75% of Americans who are overweight or obese, offering an alternative to drugs like GLP-1s or surgery. Users wear a small CGM sensor on the upper arm, which sends data to an AI-powered app. The company reported more than 10-fold growth in the past six months amid rising demand.[1]
Fouladgar-Mercer emphasized accessibility: “There is now a solution that everybody can use to help on the weight loss journey, and you don’t have to be a certain number of pounds to use it.”[4]
Real-Time Feedback Drives Sustainable Habits
The Signos app delivers personalized predictions, such as glucose spikes from specific meals, and sends alerts via Apple Watch for quick fixes like walks or squats. Users log food through photos or voice notes, gaining agency by experimenting: “What happens if I eat this?”[1][5]
It syncs with devices like smart scales and health apps to track trends in weight, sleep, and movement. Research linked to the platform shows 87% of users adjust food choices based on feedback, with nearly half moving more after spikes.[5]
- 24/7 glucose monitoring from a 15-day biosensor.
- AI-driven movement suggestions tailored to user history.
- In-app dietitian support and weekly reports.
- Habit-building tools to maintain stable glucose levels.
- Integration with Apple Health and Google Fit.
Pricing starts at $139 per month for three months or $129 for six months, including all sensors.
Beyond Diets: A New Paradigm in Metabolic Health
Signos addresses gaps in traditional approaches. Diets fail 90-95% of users long-term, and drugs provide no guidance on fueling or muscle-building. The platform promotes metabolic literacy for lasting change, especially for those transitioning off medications.[2][1]
Fouladgar-Mercer noted, “A drug doesn’t give you guidance on fueling your body or building lean muscle mass… We’re showing that real-time personalized feedback can help people make sustainable, healthy life changes.”[1]
| Plan Duration | Monthly Price | Included Sensors |
|---|---|---|
| 3 months | $139 | All needed CGMs |
| 6 months | $129 | All needed CGMs |
Key Takeaways
- Signos offers the first FDA-cleared CGM for weight management without diabetes.
- Users gain real-time insights to build habits that outlast diets or drugs.
- Backed by a massive clinical study and rapid company growth.
Signos positions glucose data as the foundation for healthier lives, proving one former athlete’s vision could shift how millions approach weight. What role do you see wearables playing in your health routine? Share in the comments.
