Healthline3-Month Intermittent Fasting Program Led to Significant Weight Loss

This randomized controlled trial (n=99) demonstrates that a 3-month time-restricted eating intervention with 8-hour feeding windows produces sustained weight loss at 12-month follow-up. The study provides valuable long-term data on TRE effectiveness, showing 85-88% adherence rates and maintained weight reduction across different timing protocols.

⚕️ Key Clinical Considerations ⚕️

• Evidence Quality: Well-designed RCT with 12-month follow-up, though results not yet peer-reviewed and sample size relatively modest for definitive clinical recommendations.
• Weight Loss Efficacy: TRE groups achieved 3.5-4.5% body weight reduction (≈8 pounds) versus 1.5% in controls, with sustained 0.7-2% weight loss at one year.
• Timing Flexibility: Early TRE (before 10am), late TRE (after 1pm), and self-selected windows showed comparable effectiveness, supporting individualized approaches.
• Adherence Advantage: High compliance rates (85-88%) attributed to simplified approach requiring no calorie counting or food restriction, only meal timing modification.
• Safety Considerations: Potential contraindications include age >75, pregnancy, diabetes requiring medication adjustment, and cardiovascular disease given conflicting 2024 AHA data.

🎯 Clinical Practice Impact 🎯

• Patient Communication: Present TRE as evidence-based option for weight management with flexibility in timing implementation. Emphasize that benefits appear independent of specific eating window, allowing personalization based on lifestyle and work schedules.
• Practice Integration: Consider TRE for motivated patients struggling with traditional calorie-counting approaches. Implement gradual transition protocols and establish clear monitoring parameters for metabolic health markers during initial weeks.
• Risk Management: Screen thoroughly for contraindications including advanced age, pregnancy, diabetes requiring precise meal timing, and cardiovascular disease. Monitor for side effects including fatigue, headaches, and potential medication timing conflicts.
• Action Items: Develop patient education materials explaining TRE protocols, establish follow-up schedules for weight and metabolic monitoring, and create referral pathways for nutritional counseling when combining with Mediterranean diet principles.
