A randomized crossover pilot study in healthy adults found that coffee and isolated caffeine produce distinct short-term immune responses despite equivalent caffeine doses. The results suggest non-caffeine coffee compounds may influence cytokine activity and caffeine metabolism, although findings remain preliminary due to the small sample size.

A post-hoc analysis of two clinical trials compared continuous calorie restriction with early time-restricted eating in adults with type 2 diabetes and overweight or obesity over three months. Both approaches improved weight, body composition, and metabolic health, with no clear superiority except for lower dropout with intermittent restriction.
