However, the volunteers additionally suffered a better discount in lean mass and bone density. This may result in diminished muscle perform and elevated danger of bone fractures if the eating regimen had been adopted for an extended interval.
Although these outcomes might point out that the OMAD eating regimen may have advantages for some points of well being, there’s nonetheless a lot to be taught. It will likely be necessary for future research to research its impact in bigger numbers of members and in different teams of individuals (as this analysis solely included younger, lean adults). It may also be necessary for research to have a look at its penalties over an extended time frame and to conduct these trials in an actual setting.
It may also be fascinating to know if the timing of the meal can additional enhance the outcomes and if the dietary profile of the consumption makes a distinction.
