My AI doppelganger tells me what to eat

What happened

Victoria Song reviews roughly 100 days with Twin Health, an AI digital twin program that predicts glucose responses to food using personal health data and continuous glucose monitoring. She reports improved labs, including triglycerides dropping by 70mg/dL, but no meaningful weight loss or hoped-for success reducing medications; some lab values were already improving before the program. Human coaching helped motivate exercise, while extensive tracking caused fatigue and raised questions about privacy and trust in higher-stakes medical uses.
