Recent research presented at the European Congress on Obesity examines how effective time-restricted eating and rapid weight loss plans are for maintaining weight in the long term.

近期在歐洲肥胖症大會上發表的研究，探討了限時飲食與快速減重計劃在長期維持體重方面的成效。

The first study, conducted by the University of Granada, looked at the effects of eating only during an eight-hour window every day for one year. Participants were divided into four groups: one group that ate for more than twelve hours a day, and three groups that used an eight-hour window (early, late, or self-chosen). The results show that the groups with time-restricted eating lost more weight—about 3kg to 4kg—compared to the control group, which only lost 1.4kg. Furthermore, this weight loss was maintained after one year, while the control group actually gained 0.4kg. Dr. Alba Camacho-Cardenosa emphasized that these results were caused by the sixteen-hour fasting period rather than the specific time of day people ate. However, Dr. Maria Chondronikola from the University of Cambridge noted that more data on calorie intake and metabolism are needed to fully confirm these findings.

第一項研究由格拉納達大學進行，探討了一年之內每日僅在八小時時間窗內進食的效果。參與者被分為四組：一組每日進食時間超過十二小時，另外三組則使用八小時時間窗（分別為早晨、傍晚或自選）。結果顯示，限時飲食組的減重效果較明顯——約 3kg 至 4kg——而對照組僅減輕 1.4kg。此外，這種減重效果在一年後仍能維持，而對照組實際上增加了 0.4kg。Alba Camacho-Cardenosa 博士強調，這些結果是由於 16 小時的禁食期所致，而非進食的具體時間點。然而，劍橋大學的 Maria Chondronikola 博士指出，需要更多關於卡路里攝取量與新陳代謝的數據，才能完全證實這些發現。

At the same time, research from Norway compared rapid weight loss with gradual weight loss among 284 adults with obesity. The rapid weight loss group followed a strict 16-week diet starting at 1,000 calories, whereas the gradual group averaged about 1,400 calories. The results demonstrated that the rapid loss group achieved a 12.9% reduction in total body weight during the first phase, compared to 8.1% in the gradual group. After one year, the rapid loss group maintained a 14.4% reduction, while the gradual group maintained 10.5%. Dr. Line Kristin Johnson asserted that these findings challenge the common belief that gradual weight loss is better for long-term success. Dr. Marie Spreckley agreed, suggesting that structured rapid weight loss could be a useful clinical strategy to reduce the pressure on public healthcare systems.

與此同時，挪威的一項研究比較了 284 名肥胖成年人的快速減重與漸進減重效果。快速減重組在 16 週內遵循嚴格飲食，從 1,000 卡路里開始，而漸進組平均攝取約 1,400 卡路里。結果顯示，快速減重組在第一階段實現了 12.9% 的總體重減幅，而漸進組為 8.1%。一年後，快速減重組維持了 14.4% 的減幅，而漸進組則維持在 10.5%。Line Kristin Johnson 博士斷言，這些發現挑戰了「漸進減重對長期成功較佳」的普遍看法。Marie Spreckley 博士對此表示認同，認為結構化的快速減重可作為一種有效的臨床策略，以減輕公共醫療系統的壓力。

Current evidence suggests that both time-restricted eating and structured rapid weight loss may be more effective for long-term obesity management than traditional gradual methods.

目前證據顯示，限時飲食與結構化快速減重在長期肥胖管理方面，可能比傳統的漸進方法更有效。
