7日間の水のみによる断食は、体全体に大きな分子レベルの変化を引き起こし、最も顕著な影響は絶食から3日目以降に現れることが分かりました。研究者らは健康なボランティアのタンパク質の変化を追跡し、こうした反応を詳細に記録しました。今回の研究結果は、長期的な断食がもたらす健康上の潜在的な利点とリスクの両方を浮き彫りにしています。
ロンドン・クイーンメアリー大学とノルウェー国立スポーツ科学大学の研究チームは、7日間の断食を行う健康なボランティア12名を対象に調査を実施しました。研究チームは毎日血液サンプルを採取し、約3,000種類のタンパク質を分析することで体内の変化を観察しました。その結果、開始から2〜3日以内に体がブドウ糖の利用から脂肪の燃焼へと切り替わり、平均で5.7キログラムの減量が見られました。断食終了後に食事を再開すると除脂肪組織の減少分はほとんど回復しましたが、脂肪の減少分は維持される傾向にありました。

A Stanford Medicine-led randomized trial in the United States found that a five-day-per-month fasting-mimicking diet was linked to improved patient-reported symptoms and lower biological markers of inflammation in adults with mild-to-moderate Crohn’s disease. The results were published in Nature Medicine.

During the ongoing Ramadan, nearly half the players in Procyon's P11 team in Uppsala are fasting, along with some coaches. When trainings cannot be scheduled after sunset, they break their fast together on the field. Player Josef Fandi, 14, describes it as manageable despite thirst and hunger.
A new study shows that a high-fat ketogenic diet can normalize blood sugar levels in mice with hyperglycemia and enhance their muscles' response to exercise. Led by researcher Sarah Lessard, the research indicates that combining the diet with physical activity leads to better oxygen use and endurance. The findings suggest potential benefits for metabolic health when diet and exercise are paired.

New research links chronic stress combined with late-night eating to increased risks of constipation, diarrhea, and reduced gut microbiome diversity. Scientists analyzed data from over 11,000 participants in a national survey. The findings are set to be presented at Digestive Disease Week on May 4.
The majority of ulama, including the Syafi’i school, state that sleeping all day does not invalidate the Ramadan fast as long as the intention is made at night. This view is based on Imam an-Nawawi’s explanation in a fiqh book. However, excessive sleep is advised against to avoid neglecting religious duties.
