CGM can help individuals monitor their blood glucose levels throughout the day, which can be helpful in identifying patterns and triggers for overeating or consuming high-carbohydrate meals. By understanding how their diet affects their blood glucose levels, individuals can make more informed choices about what they eat, and make adjustments to their diet as needed.
CGM can help individuals stay accountable and motivated. By seeing the real-time impact of their food choices on their blood glucose levels, individuals can feel more connected to the consequences of their choices, which may help them make healthier choices over time
CGM can be helpful in identifying and addressing underlying issues with insulin resistance or other metabolic issues. By tracking blood glucose levels over time, individuals and their healthcare providers can identify patterns or trends that may suggest an underlying metabolic issue that needs to be addressed.
There is some preliminary evidence to suggest that CGM can be helpful for weight loss. Here are a few studies that have investigated this topic: In a randomized controlled trial published in the journal Obesity in 2018, researchers assigned overweight or obese adults to either use a CGM device for 12 weeks or to a control group that did not use the device. The participants in the CGM group lost significantly more weight than those in the control group, and they also showed improvements in their blood glucose control.
A study published in Diabetes Technology & Therapeutics in 2019 examined the use of a CGM device in combination with a structured weight loss program in overweight or obese adults with type 2 diabetes. The participants who used the CGM device lost significantly more weight than those who did not, and they also showed improvements in their blood glucose control and other metabolic parameters.
