Metabolic Cheat Sheet
Six core concepts that explain how metabolism works — and what moves the needle most.
Glycation & AGEs
- →Glycation = glucose bonding to proteins/fats, damaging cells
- →HbA1c measures average glycation over 3 months
- →Cooking at high heat creates AGEs — prefer low-slow methods
- →Quercetin & Carnosine inhibit glycation naturally
Ketosis & Fat Adaptation
- →Ketosis: liver produces ketones when carbs <50 g/day
- →BHB (beta-hydroxybutyrate) is a clean, anti-inflammatory fuel
- →Fat adaptation takes 3–6 weeks of consistent low-carb
- →Target blood ketones: 0.5–3.0 mmol/L for nutritional ketosis
Insulin Sensitivity
- →Cells respond to insulin to absorb glucose from blood
- →Resistance = cells ignore insulin → chronic high blood sugar
- →Exercise is the #1 non-pharmaceutical insulin sensitizer
- →Fasting 12–16 hrs restores receptor sensitivity overnight
Mitochondrial Health
- →Mitochondria are ATP factories — metabolic rate depends on them
- →Zone 2 cardio is the most potent mitochondrial biogenesis trigger
- →CoQ10 & NAD+ are critical cofactors for ATP synthesis
- →Cold exposure & sauna upregulate mitochondrial efficiency
Inflammation & mTOR
- →Chronic low-grade inflammation drives metabolic dysfunction
- →mTOR: growth pathway activated by protein/insulin/exercise
- →Fasting inhibits mTOR → triggers autophagy (cellular cleanup)
- →CRP <1.0 mg/L is the optimal inflammatory marker target
Metabolic Flexibility
- →Ability to switch between glucose and fat as primary fuel
- →Poor flexibility = reliance on frequent meals to avoid crashes
- →Improve with: IF + Zone 2 + low-carb cycling
- →RQ (Respiratory Quotient) is the gold-standard flexibility test

Healthy vs. Unhealthy Lifestyle Factors
What moves metabolic health in the right direction — and what quietly works against it.
✅ Metabolically Supportive
Post-Meal Walking
10–20 min walk after eating blunts glucose spikes by up to 30%
Proven
Zone 2 Cardio
30–60 min conversational pace boosts fat oxidation & mitochondria
Essential
7–9 Hours of Sleep
Poor sleep raises cortisol and fasting glucose within one night
Critical
Intermittent Fasting
12–16 hr window restores insulin sensitivity and lowers fasting glucose
Proven
Strength Training 2–4×/wk
Increases GLUT4 transporters, removing glucose directly from blood
Essential
Stress Management
Meditation & breathwork lower cortisol, which directly disrupts insulin
Impactful
Protein-First Meal Sequencing
Eating protein & fiber before carbs flattens the glucose curve
Proven
❌ Metabolically Disruptive
Sedentary Behavior
Sitting 8+ hrs/day reduces insulin sensitivity independently of exercise
High Risk
Chronic Poor Sleep
Under 6 hrs consistently doubles insulin resistance risk within weeks
Critical
High Fructose Consumption
Liver processes fructose directly → drives visceral fat & fatty liver
Avoid
Chronic Psychological Stress
Cortisol chronically elevates blood glucose and promotes fat storage
High Risk
Snacking Constantly
Keeps insulin chronically elevated — prevents fat oxidation all day
Limit
Alcohol (Regular)
Blocks fat oxidation for hours and disrupts sleep architecture
Minimize
Ultra-Processed Carbohydrates
Hyper-palatable foods designed to override satiety signals & spike glucose
Avoid
Metabolic Training Protocols
Exercise is the most powerful metabolic intervention available without a prescription. These four modalities each address a different mechanism.
Strength Training
2–4× per week
Increases GLUT4 density in muscle. Each session creates insulin-independent glucose uptake for 24–48 hrs.
Zone 2 Cardio
3–5× per week · 30–60 min
Conversational pace. The most potent trigger for mitochondrial biogenesis and fat oxidation capacity.
HIIT / Sprint
1–2× per week
Short bursts rapidly deplete muscle glycogen, creating a glucose “sink” that improves sensitivity for hours.
Post-Meal Walk
Daily · 10–20 min
The single highest ROI habit. Blunts post-meal glucose spikes by 20–30% without gym equipment.
CGM & Data Tracking
Continuous glucose monitoring turns abstract metabolic concepts into real, personal, actionable data. These are the four numbers that matter most.
<140
Post-Meal Peak Target
Non-diabetic optimal range. Peaks above 140 mg/dL cause accelerated glycation of proteins and vessels.
<30 min
Time Above 140 mg/dL
Minimize “time in hyperglycemia” daily. CGMs make this trackable for the first time without labs.
Flat Curve
Glycemic Variability Goal
Lower glycemic variability (GV) predicts longevity and cognitive health better than average glucose alone.
Fiber First
Meal Order Intervention
Eating vegetables → protein → carbs reduces glucose peak by up to 37% versus carbs first. Confirmed by CGM data.
14-Day Metabolic Reset
A four-phase protocol to restore baseline metabolic function, reduce glucose variability, and build durable new habits.

Common Questions
Evidence-based answers to the most common metabolic health questions.
How long until I see measurable results?
Subjective improvements (energy, sleep, fewer crashes) typically emerge within 3–7 days of removing refined sugars and adding post-meal walks. Objective blood markers like HbA1c require 8–12 weeks to reflect meaningful change, as they represent a 3-month average. CGM data, however, shows real-time improvement within the first week.
Is a Continuous Glucose Monitor (CGM) necessary?
Not essential, but extraordinarily useful. A 2–4 week CGM trial is the fastest way to identify personal food sensitivities (often surprising — rice vs pasta, for instance). For most people, consistent movement, whole food eating, and annual labs are sufficient to manage metabolic health without ongoing CGM use.
Can supplements fix insulin resistance?
Supplements are adjuncts, not solutions. Magnesium (300–400 mg), Berberine (500 mg 3×/day), and Omega-3s all show evidence for improving insulin sensitivity at the margins. But building muscle mass through resistance training is 5–10× more powerful than any supplement. Diet and movement are the foundation — supplements fill documented gaps.
What if I can’t do 16:8 intermittent fasting every day?
A consistent 12-hour overnight fast (e.g., 8pm–8am) delivers the majority of IF’s benefits and is sustainable for most people. Prioritize it on non-social days and use a 12-hour window as your floor. The consistency of the habit matters more than the window length.
How does sleep affect blood sugar?
Dramatically. Even a single night of under 6 hours of sleep raises next-morning fasting glucose and cortisol, impairs insulin sensitivity, and increases appetite (particularly for high-carb foods) the following day. Chronic sleep restriction is now classified as an independent risk factor for metabolic syndrome, regardless of diet.
