Dietary sugars and body weight: systematic review and meta-analyses of randomised controlled trials and cohort studies
Te Morenga LA, Mallard S, Mann J
High-confidence evidence from multiple solid studies
Summary
糖類の摂取量と体重変化の関係を評価した30件以上のRCTと観察研究のメタ分析。等カロリー条件下では糖類の増減だけでは体重に有意差はなかった。しかし砂糖を増やした研究では総カロリー摂取が増え体重増加が生じており、砂糖の「過食誘発性」が重要因子とされた。
Key findings
- 1
等カロリー条件（糖類のみを変更してカロリーを揃えた）では、砂糖の多寡で体重への有意差はなかった
- 2
砂糖摂取量を増やした食事では総カロリー摂取が増え、0.75kg程度の体重増加が見られた
- 3
砂糖摂取量を減らした介入では0.8kg程度の体重減少が見られたが、カロリー削減効果との分離が難しい
- 4
砂糖は過食を誘発しやすい特性（血糖急上昇・低い飽和感・嗜好性）により摂りすぎになりやすい

Do Foods That Spike Blood Sugar Make You Fat? Blood Sugar Spikes and Body Fat vs. Research
"White rice, bread, and sugar spike blood sugar → insulin is released → fat is stored" — this is the foundational theory behind 'carbs make you fat.' Let's examine the 'carbohydrate-insulin model' against current research.

Is 'How Much You Eat' Really More Important Than 'What You Eat'? Diet Quality vs. Quantity vs. Research
"As long as you hit your calorie target, eat whatever you want (IIFYM)" vs. "regularly eating ultra-processed foods disrupts your body" — which is closer to the research? Let's establish the evidence-based priority between diet quantity and quality.
