What I Learned from Wearing a CGM for 10 Days After a 2 Year Break

Why Now

I initially used a Continuous Glucose Monitor (CGM) to address my insulin resistance and occasionally during my pregnancy. Eventually, I stopped because I felt I no longer needed it and sometimes I become too obsessed with tracking my numbers. Additionally, it can be quite expensive, so it wasn’t a necessity for me.

After having my daughter, tracking my glucose levels wasn’t a priority. I had an unplanned c-section, and my focus was on recovery and caring for a newborn. But now, I’m in a new season with a toddler who is becoming more independent, allowing me some extra time for myself. I knew my eating habits had slipped due to sleepless nights and the need for quick meals, so I decided it was time to start tracking again. I wanted to see where my glucose levels stood and ensure I was maintaining good health.

What I’m Doing Differently

• Different CGM: I’m using a different type of CGM this time. Previously I used the Freestyle Libre, now I am trying the DexcomG7 (I’ll do a comparison in an upcoming episode).
• Sharing My Journey: Previously, most people didn’t know I was wearing a CGM. Now, I’m sharing my experience openly to help others understand the importance of glucose monitoring.
• Detailed Food Tracking: I’m trying to input more information about my food into the Levels app to focus on macros, though it’s time-consuming.
• Avoiding Experiments: Unlike many who test how various foods affect their blood sugar, I’m not experimenting with things like Twix bars. I already know the effects of such foods, so I’m focusing on meals and snacks that keep my levels stable.
• Estimating Curves: I’m checking my actual levels less and using the glucose curve as an estimate.

What I Learned from 10 Days

• Impact of Snacking: Little snacks before meals or eating my daughter’s leftovers do impact my glucose levels.
• Sleep’s Influence: Sleep deprivation shows in my glucose levels, leading to higher morning levels and more susceptibility to spikes and crashes.
• Investigating Spikes: Sometimes I need to look closer at products to understand unexpected spikes, like with Body Armor Lyte beverages or beef jerky with extra sauces.
• Meal Planning: Not planning ahead with a toddler often results in quick meals like pizza, which can spike my glucose.
• Carb Cravings: Going too long without eating leads to strong carb cravings.
• Enjoying Tracking: Knowing my numbers makes me feel less tired and more energetic. It’s actually fun!
• Go-To Meals: My protein smoothies are key for stable levels throughout the day.
• Flexibility with Food: You can’t always control what you eat when with family or friends. Just do your best and get back on track afterward.
• Balancing Meals: Even a healthy bread sandwich needs fat and protein to prevent a spike.
• Timing Matters: The same meal can have different effects at different times. For instance, sourdough pancakes spiked my levels differently on different days.

Overall, I learned that while I had some larger spikes and occasional high morning levels, my previous efforts are still paying off. I constantly think about optimizing my meals and snacks for fuel and stability, with the occasional treat. I’m excited to wear my next CGM and share my findings! Stay tuned for more.

Understanding how our bodies respond to food, exercise, stress, and lifestyle helps us piece together what works for us. This looks different in each season of our lives. When I first started this journey, I was in my late 20s with fewer responsibilities. Now, with a busy toddler, rest and routine look different. Whatever season you’re in, it’s always a good idea to check in on your metabolic health. I plan to do this once a quarter to keep myself accountable.
