2/5
Weak
evidence
Fat loss evidence brief
Green coffee extract
May modestly affect weight or cardiometabolic markers in some trials, but the evidence is not strong enough for a gym fat-loss recommendation.
Headline Finding
Meta-analyses report modest anthropometric effects, but study quality and durability limit practical confidence.
Dose Context
Chlorogenic acid content, caffeine content, and extract quality vary; older weight-loss claims relied on limited or methodologically weak data.
Important Caveat
The body-weight signal is weak and does not support fat-burner positioning.

How To Read This Rating
The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
