Intermittent Fasting

Time-restricted eating (TRE) is a simple way to align when you eat with your body’s daily rhythms by keeping calories within a consistent window each day. Done well, it can improve metabolic health, sleep timing, and appetite regulation without requiring calorie counting. This guide covers how TRE works, who it helps most, how to implement it, and where caution is warranted.

Fasting is the intentional practice of not eating for a set period, often used to improve metabolic health, simplify eating, and support weight management. This guide explains how fasting works in the body, which approaches are most practical, what benefits are supported by research, and who should avoid or modify fasting for safety.

Your eating window is the daily time period when you consume calories. Adjusting it, most often by shortening it and aligning meals earlier in the day, can influence appetite, blood sugar, sleep, and cardiometabolic health. This guide explains how eating windows work, who they help most, what the research actually supports, and how to implement a plan safely.
