Intermittent Fasting vs. Caloric Restriction: What 40+ Clinical Trials Prove

Frequently Asked Questions

Direct, evidence-grounded answers to top health, fitness, and nutrition questions.

How much protein can the body actually absorb per meal for muscle growth?
The claim that the human body can only absorb 30g of protein per meal is a disproven myth. While 25g to 35g of high-quality protein (providing 2.7g-3.5g of leucine) maximally triggers acute Muscle Protein Synthesis (MPS), larger boluses (up to 100g) are methodically digested over a 12-hour period, sustaining amino acid elevation and reducing whole-body protein breakdown.
Does intermittent fasting burn more body fat than regular dieting?
No. When daily calories and protein are strictly equated between groups in metabolic wards, intermittent fasting (including 16/8 time-restricted feeding) does not burn more fat than standard daily caloric restriction. Its real-world success stems from behavioral friction that eliminates evening snacking and simplifies calorie control.
What is Zone 2 cardio and why is it essential for longevity?
Zone 2 is low-intensity aerobic exercise where energy is derived predominantly from fatty acid oxidation and blood lactate remains below 2.0 mmol/L. It stimulates mitochondrial biogenesis in Type I muscle fibers, clears dysfunctional mitochondria, and builds the aerobic base that supports long-term metabolic and cardiovascular health.
Is a loading phase required when starting Creatine Monohydrate?
No. While taking 20g daily for 5-7 days saturates muscle stores in about a week, taking a flat maintenance dose of 5g per day achieves identical saturation within 3 to 4 weeks with zero digestive distress.
