Effects of intermittent fasting on body composition and clinical health markers in humans
Tinsley GM, La Bounty PM
Evidence is still building up
Summary
ヒトを対象とした断食プロトコル（IF）の体組成・健康指標への影響を包括的にレビュー。十分なタンパク質摂取を維持した場合、断食期間中の筋タンパク質分解は限定的であることが示された。総タンパク質・カロリー摂取量が等量なら、IFと通常食の筋肉維持能力は同等に近い。
Key findings
- 1
16〜24時間の断食では、タンパク質摂取量が確保されていれば顕著な筋タンパク質分解は起きにくい
- 2
IFと通常の食事パターンを比較した研究では、総カロリー・タンパク質量を等量にした場合の除脂肪量変化に有意差がなかった
- 3
断食中の激しいトレーニングや慢性的なタンパク質不足はリスクを高める
- 4
筋肉維持の鍵は食事タイミングより24時間の総タンパク質・総カロリー摂取量にある

How to Break Through a Diet Plateau: The Science of Stalling Weight Loss
The primary cause of weight loss plateaus is 'metabolic adaptation (adaptive thermogenesis)' — a physiological response where the body senses caloric restriction and reduces energy expenditure. Refeed days, diet breaks, and recalibrating calorie targets are evidence-supported strategies to break through.

The Science of Diet Rebound: Why Weight Returns After Dieting and How to Prevent It
Rebound is driven not by willpower failure but by physiological defense mechanisms (metabolic adaptation, leptin decline, and appetite hormone changes). However, research identifies strategies to minimize these effects.

Why Women Find Fat Loss Harder: Understanding the Sex Differences in Dieting from Research
Women's hormonal environment (estrogen, progesterone), fat tissue distribution characteristics, and fuel utilization patterns during aerobic exercise differ from men's, producing different body weight loss rates and body composition changes under identical caloric restriction. However, the more accurate framing is not 'women can't lose fat' but rather 'different approaches are optimal for female physiology.'
