Your CGM Spike May Not Be Caused by Your Meal

A continuous glucose monitor shows trends in interstitial fluid, not an exact real-time blood measurement. Koff warns that exercise, stress, sleep, and menstrual-cycle changes can alter glucose, so blaming the last meal can lead to unnecessary carbohydrate restriction.

  • CGMs measure interstitial fluid rather than directly sampling blood
  • Koff says more than 40 factors affect blood sugar and only 10 are nutritional
  • Intense exercise can appropriately raise glucose
  • Cooldown, breathing, sleep, and cycle context can change interpretation

“there are 40 plus factors that impact your blood sugar 10 of them are nutrition just 10”

“intense workout is intense on the body stress on the body bumps our blood sugar up I want your blood sugar to go up”

Losing Weight While Losing Health Is a Failed Outcome

Koff says GLP-1 medication can be an effective tool but scale weight alone is the wrong success measure. She emphasizes preserving lean body mass, monitoring nutrient status, and avoiding major cycles of loss and regain.

  • Weight-loss surgery and GLP-1 medication can share a GLP-1 mechanism
  • Health gain matters alongside weight loss
  • Appetite suppression can worsen existing nutrient insufficiencies
  • Lean-body-mass loss and later regain are important risks to monitor

“there are a lot of ways that you can lose weight if you don't gain Health you don't really get what you want”

Ashley Koff · 15:30

“over the course of the next year you will likely regain a good percentage if not all of your weight”

Why Your Body Needs More Than Omega-3

Koff argues that foods naturally provide a mix of fatty acids, including omega-3, 6, 7, and 9. Different fats contribute to inflammation resolution, hormonal communication, and hair, skin, and nail health, so an omega-3-only view can miss useful variety.

  • Fatty foods contain multiple fatty acids, not a single isolated omega
  • Omega-6 includes GLA, which Koff links to hair, skin, nails, and hormones
  • A diverse daily fat intake can come from foods such as salmon, hemp, chia, olives, and avocado
  • Blanket claims that all seed oils are harmful erase meaningful differences

“there's omega3 there's Omega 6 there's Omega 7 there's Omega 9”

Ashley Koff · 04:30

“pretty much any food that has fat has a variety of these”

Natural GLP-1 vs Medication: Decaf Coffee and a Red Eye

Koff compares naturally produced GLP-1 with a decaf coffee and GLP-1 medication with a four-shot red eye. Her point is that medication delivers more activity for longer, while improving digestive function may still support the body's natural production whether or not medication is used.

  • The body naturally produces GLP-1
  • Medication supplies a stronger, longer-lasting effect
  • GLP-1 receptors exist beyond the pancreas
  • Natural optimization and prescribed medication are not presented as mutually exclusive

“if we want to compare the natural hormone glp1 to OIC I like to say it's like decaf coffee versus a red eye”

Ashley Koff · 12:00

“when you take the medication it sticks around for like 30 minutes”

Root-Cause Medicine Works on the Roots, Not the Fruit

Koff cuts through overlapping labels such as integrative, lifestyle, and functional medicine by focusing on the shared intent: investigate upstream causes rather than patch visible outcomes. She contrasts a doctor's diagnostic role with her own emphasis on personalized implementation—the how.

  • Different health disciplines often overlap in root-cause intent
  • Visible outcomes are the fruit; upstream causes are the roots
  • Diagnosis and implementation are distinct roles
  • Implementation must fit the individual to become actionable

“we should call this root cause medicine so essentially think of a tree and get into the roots”

Ashley Koff · 41:30

“my focus is on the how and when you get into the how it has to be personalized”
