Phase 3: Making Your Shift
MAP: Metabolism, Appetite
Insulin resistance transforms your body's energy regulation, making weight loss significantly harder. When cells stop responding properly to insulin, your body increases production, promoting fat storage while triggering persistent hunger and cravings—especially for carbohydrates.
How this headwind creates over fueling:
Insulin resistance creates a metabolic catch-22. Your pancreas produces more insulin to manage blood sugar, but this excess insulin promotes fat storage while making you hungrier. Think of it like a thermostat that's constantly miscalibrated — your body keeps cranking up the heat (hunger) even when the room (your energy stores) is already warm.
This metabolic miscommunication happens through several pathways:
First, insulin's primary job is storing energy. When resistance develops, your body compensates with higher insulin levels, directly promoting fat accumulation—particularly around your abdomen.
Second, insulin resistance creates blood sugar volatility — but in a complex way. When you're eating normally or in caloric balance, your glucose rises higher after meals and falls more slowly than it should, as your cells resist insulin's efforts to clear glucose from your bloodstream.
However, when you suddenly restrict calories or carbohydrates, something counterintuitive happens: that same insulin resistance can cause hypoglycemia (low blood sugar). This occurs because your body is still producing excess insulin to combat resistance, but now there's insufficient incoming glucose to match it. The result is that unpleasant "crash" feeling—shaky, irritable, foggy—that drives urgent hunger even after a substantial meal.
This glucose rollercoaster explains why many insulin-resistant people feel trapped: eating normally keeps them in a state of persistent high insulin that promotes fat storage, but restricting intake triggers hypoglycemic episodes that drive powerful cravings and hunger.
Third, insulin resistance impairs your brain's ability to recognize satiety signals. Even with sufficient energy stores, your brain receives "empty tank" messages, driving persistent hunger.
This headwind often works alongside Sleep Disruption and Stress, creating a perfect storm of appetite dysregulation.
Signs you’re facing this headwind:
You're likely battling insulin resistance if:
You experience energy crashes and intense hunger 2-3 hours after meals
Calorie restriction or low-carb meals leave you feeling shaky, irritable, or foggy
Carbohydrate-rich foods trigger strong cravings and hunger rebounds
You notice dark, velvety skin patches in body folds (acanthosis nigricans)
Your continuous glucose monitor shows exaggerated post-meal glucose spikes followed by slow return to baseline followed by potentially a dip below normal glucose if you’re restricting
Blood work reveals elevated triglycerides and/or low HDL cholesterol
You feel unusually thirsty throughout the day
This headwind becomes particularly noticeable when first waking up, several hours after meals, or when attempting restrictive diets.
Activity 1:
You can test your level of insulin resistance by asking your doctor for a fasting serum glucose and a fasting serum insulin level drawn at the same time and using this Insulin Resistance Calculator (HOMA-IR): Calculator.
While HOMA-IR provides a useful estimate of insulin resistance, it's an imperfect measure that doesn't account for individual metabolic variations, can be affected by acute stress or illness, and may not correlate perfectly with more precise (but impractical) laboratory methods like the hyperinsulinemic-euglycemic clamp.
Tacking strategies:
Protein-First Eating: Begin each meal with protein before carbohydrates. This simple sequence change reduces post-meal glucose spikes by up to 39%.
Consider this tactic: Rearrange your plate — don't change what you eat, just the order.
Moderate, Not Severe Restriction: Avoid extreme calorie cutting or carb elimination, which can trigger hypoglycemic episodes. Instead, aim for modest 300-500 calorie deficits with balanced macronutrients.
Consider this tactic: Focus on portion size reduction rather than eliminating food categories.
Post-Meal Movement: Take a 10-minute walk after your largest meal of the day. Brief movement improves insulin sensitivity immediately by activating glucose transporters.
Consider this tactic: Pair with something enjoyable (podcast, phone call) to establish consistency.
Sleep Optimization: Prioritize 7-8 hours of quality sleep nightly. Even one night of poor sleep can reduce insulin sensitivity by 25%.
Consider this tactic: Create a 30-minute pre-sleep ritual that signals your body it's time to wind down.
Balanced Meals: Meet your protein and fibre targets at each meal to prevent both high glucose peaks and subsequent crashes.
Consider this tactic: Aim for meals that take at least 20 minutes to eat, giving your body time to process incoming nutrients.
Consider medical support if you've implemented these strategies consistently for 3+ months without improvement, or if you have a family history of type 2 diabetes.
Success looks like:
Improvements in insulin sensitivity develop gradually, typically over 3-6 months of consistent practice. You'll notice reduced hunger between meals first, followed by more stable energy throughout the day.
Track these indicators in your Ship's Manifest:
Decreased frequency of post-meal energy crashes
Reduction in hypoglycemic episodes when eating balanced meals
Longer satisfaction after eating protein-rich meals
Reduced thirst and improved energy consistency
Gradual changes in waist circumference
Celebrate when you notice you can introduce a modest calorie deficit without experiencing intense hunger or hypoglycemic symptoms—this signals improving insulin sensitivity. Small wins include needing fewer snacks between meals and feeling satisfied with smaller portions.

Today I’ll:
Take a 10-minute walk after my largest meal today, noting in my Captain's Log how my energy and hunger feel in the hours afterward compared to a typical day. I'll also pay attention to the composition of my meal (protein, fat, carbs) and how that affects my post-meal energy.
