This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor answer listener mailbag questions from California, the UK, France, Washington, Wyoming, and beyond.

The team breaks down why Dr. Cooper does not recommend calorie tracking (and when limited tracking can make sense), how to build confidence in eating without data, and why “mechanical eating” sometimes needs medical customization—especially for people with slow gut transit or gastroparesis-like symptoms.

They also dig into bile acid malabsorption after gallbladder removal, when metformin side effects deserve a second look, what we currently know about COVID-19’s potential impact on metabolic health, and why metformin and GLP-1 medications can be complementary—particularly in PCOS.

Key Takeaways
• Long-term calorie tracking can override physiologic cues and reinforce diet mentality.
• Short-term, targeted tracking may be useful when guided by a clinician (e.g., nutrient deficiencies ).
• Obesity and abnormal appetite are both manifestations of metabolic dysfunction—not simple cause and effect.
• Mechanical eating is a framework, not a rigid rule—timing and food choices may need medical tailoring.
• Post-gallbladder diarrhea may reflect bile acid malabsorption and can be treatable.
• Metformin and GLP-1s often complement each other because they target different metabolic states (fasting vs fed).

Dr. Cooper’s Actionable Tips
• Stop daily calorie counting—focus on consistent patterns and metabolic nourishment.
• Use mechanical eating basics: eat every few hours, include all food groups, and reduce chemical additives when possible.
• If you’re transitioning away from tracking, consider a dietitian skilled in diet-mentality recovery.
• If frequent eating worsens sleep or bloating, work with a medical dietitian to adjust intervals and food types (especially with slow GI transit).
• If chronic diarrhea appears (especially after gallbladder removal), ask your clinician about bile acid malabsorption and treatment options.
• Use labs to guide therapy: fasting insulin can signal metformin benefit; post-meal patterns can point toward GLP-1 needs.

Notable Quote
“Once you start using tracking to stay in a calorie range or a carbohydrate range, you’re putting your brain in front of your physiologic intuition—your body is sending you important cues all the time.”
—Dr. Emily Cooper
