Caralluma fimbriata at 500-1,000 mg/day has shown modest appetite suppression and waist circumference reduction in a few small RCTs. Kuriyan et al. (2007, n=50) found significant reductions in waist circumference and hunger. Evidence is limited but the appetite-suppressing mechanism is plausible.
Caralluma fimbriata has a plausible mechanism (pregnane glycosides affecting appetite pathways) and a long traditional use history in India. Clinical evidence is limited to a few small trials showing modest appetite suppression and waist circumference reduction. No significant weight loss has been demonstrated. It may be useful as part of a broader appetite management strategy.

Upper limit: 1,000 mg/day was the highest dose in clinical trials
Safety profile: Generally Safe
The limited clinical data shows modest appetite reduction (reduced hunger and desire to eat) at 1,000 mg/day. The effect is not dramatic but consistent with its traditional use as a famine food. It may help with portion control and snacking but should not be relied upon as a sole weight loss strategy.
Caralluma has weaker evidence than glucomannan (fiber-based satiety) or caffeine (stimulant-based appetite suppression). Its advantage is a different mechanism (pregnane glycosides) and minimal stimulant effects. It could complement other approaches without adding caffeine-related side effects.
Short-term studies (up to 60 days) show a good safety profile. However, long-term safety data is lacking. The plant has been consumed traditionally in India for centuries during food scarcity, suggesting reasonable safety, but formal long-term studies are needed.
