Weight loss gadgets: They provide data to help consumers achieve diet goals, but it still won’t be easy

"We're taking on weight loss by giving every body a voice," says CGM-based company Signos. A promo for Lumen shares: "You hold in your lungs the secret to sustainable weight loss." But even as people in the field have seen "significant" results from incorporating these tools into weight loss programs, they acknowledge that no single approach seems able to do it all. There is also scant research on CGMs' effectiveness in improving the health of people without diabetes, let alone prompting weight loss. Signos, which focuses on weight loss, uses artificial intelligence to set a "weight loss range" for customers depending on their general glucose ranges and level of fitness.
