Time-restricted eating (16:8)

Easiest to sustain, smallest measured effect, weakest controlled evidence.

Largest effect

5:2 and alternate-day

Largest effect sizes in comparative meta-analysis, highest dropout.

Best mechanism

Early eating windows

The circadian evidence is the best mechanistic case in the field.

Clinical only

Extended fasting

Serious clinical research exists, mostly in oncology. Not a wellness protocol.
