🙆 Not Overweight but Prediabetic? You’re Not Alone.
You don’t have to overeat or be overweight to have elevated blood sugar. I often see lean clients with prediabetes or type 2 diabetes who eat a balanced diet. Prediabetes and type 2 diabetes are so often associated with overeating and being overweight that conventional approaches are not designed to fit the growing number of people who don’t fit the mold. I dig in with these clients, and we dig for root causes beyond “calories.”
Common contributors I assess:
• Macronutrient imbalance (high sugar/refined flours) → bigger glucose swings and insulin demand
• Chronic stress/cortisol → raises glucose and drives insulin resistance
• Inflammation → impairs insulin signaling
• Toxicants/“obesogens” (e.g., persistent organic pollutants) → linked with insulin resistance/diabetes risk
• Mitochondrial dysfunction → inefficient usage of glucose leads to hyperglycemia and insulin resistance
• Autoimmunity (Type 1, LADA) → adult-onset autoimmune diabetes can be misread as “type 2” in lean people
👉 What this means: If your A1c or fasting glucose is creeping up but you’re undereating or normal weight, it’s time to look under the hood and assess for stress, inflammation, mitochondrial health, toxicity burden, and autoimmune markers.
How I help: personalized nutrition (protein, healthy fat, fiber to stabilize blood sugar), nervous system support, targeted labs, and a sustainable plan. If this sounds like you, let’s talk.
