Energy balance
Substituting whole grains for refined grains resulted in a greater resting metabolic rate (RMR) increase of 48 ± 23 kcal/d compared to refined grains.
Incorporating whole grains into the diet may enhance metabolic rate, aiding in energy balance.
StrongSupportsmedium confidence
However, changes in RMR ([WG versus RG mean difference ± SE] 48 ± 23 kcal/d; p = 0.04) were greater in WG versus RG.
Why this rating
Based on the randomized controlled trial design.
