How fasting switches the body from storage to fuel use
Jamnadas explains fasting as a return to the body’s intended “feeding–fasting” cycle. The key idea is that frequent eating keeps the body stuck in storage mode, whereas fasting forces it to use stored energy.
The timeline: glucose → glycogen → fat (ketones)
He lays out a simple sequence of what fuels the body uses as hours pass without food. Once glucose and glycogen are depleted, the body transitions to fat burning and ketone production.
Why insulin is the central issue (and why frequent eating breaks the system)
The conversation centers on insulin as the main hormonal driver of fat storage and metabolic dysfunction. Constant eating keeps insulin elevated, preventing fat breakdown and promoting insulin resistance.
From cardiology clinic to root cause: heart disease with ‘normal’ labs
Jamnadas describes noticing patients with heart disease despite acceptable cholesterol, blood pressure, and no diagnosed diabetes. This clinical puzzle prompted him to look beyond standard markers.
Catching early dysfunction: mild glucose intolerance and metformin resistance
He began testing for subtle glucose abnormalities and found many had impaired glucose control. Treating earlier (e.g., with metformin) was controversial but seemed to improve outcomes.
The Kraft test revelation: massive insulin spikes even when glucose looks fine
By measuring insulin response (not just glucose), he found many patients produced extremely high insulin after a glucose load. This highlighted hyperinsulinemia as a hidden problem preceding diabetes.
‘By the time you’re diabetic, it’s too late’: the long lead-in to damage
He argues that vascular injury can accumulate for 15–20 years before diabetes is diagnosed by common criteria (A1C, fasting glucose). The damage occurs during years of compensatory high insulin.
Why fasting became his main tool to lower insulin
Jamnadas frames fasting as the most direct way to reduce insulin because insulin production drops when you stop eating. With lower insulin, the next meal requires less insulin due to improved sensitivity.
Insulin, nitric oxide, and blood pressure: rethinking ‘essential hypertension’
He links high insulin to higher blood pressure through reduced nitric oxide and vasoconstriction. Fasting, by lowering insulin, improved vasodilation and led to substantial blood pressure drops.
Fat loss mechanics: lowering insulin unlocks stored fat
He reiterates insulin’s role as a storage hormone and describes fat loss as removing the ‘padlocks’ on fat stores. In his observation, fasting produced more favorable body composition/appearance than frequent low-calorie meals.
Unexpected patient benefits: mood, sleep, and brain effects (BDNF)
Patients reported feeling happier, more energetic, and sleeping better while fasting. He attributes some of this to fasting-related neurochemistry such as increased BDNF, which may enhance alertness and brain resilience.
Inflammation and physical comfort: joint pain, CRP, and gut symptoms
He notes improvements in aches, pains, and digestive symptoms that seemed disproportionate to the amount of weight lost. Objective inflammation markers (CRP) also improved in his fasting patients.
