Black seed oil research includes appetite and body composition. A crossover study explored these outcomes in women with overweight or obesity.
Study design
Randomised, double-blind crossover trial; 45 women with overweight or obesity; two eight-week intervention periods and a four-week washout.
Reported findings
A 2021 crossover trial in 45 women with overweight or obesity compared Nigella oil and placebo across two eight-week periods separated by a washout. Its abstract described improvements in some outcomes but used inconsistent wording about the direction of changes in weight-related measures.
Interpreting the result
The abstract contains inconsistent wording about the direction of some anthropometric changes. We therefore do not report a precise weight-loss claim from it. The limited population and crossover design also require attention to period and carryover effects.
Why this study is useful
The study explored appetite, body fat and other measurements across two treatment periods. The abstract contains inconsistent wording about the direction of some weight changes, so we do not translate it into a promised amount of weight loss. The appetite and body-composition questions remain relevant areas for further research.
