Binciken ya yi amfani da Bayesian multilevel model, kuma sakamakon an ba da shi a matsayin standardized mean differences (SMD) tare da 95 % credible intervals. Waɗannan sune ƙimar da suka fito:
- Protein da carbohydrate vs. placebo (aikin juriya): SMD = 0.57 (95 % CI = 0.20‑0.93).
- Protein tsaf vs. placebo (aikin juriya): SMD = 0.37 (95 % CI = 0.02‑0.71).
- Protein tsaf vs. placebo (ƙarfi): SMD = 0.72 (95 % CI = 0.18‑1.27).

Ka yi tunanin ƙungiyoyi biyu na ‘yan wasa. Ɗaya yana samun shake na protein a kan abincin yau da kullum, dayan kuma yana samun placebo mai ƙananan kalori. Idan rukunin shake ya fi ƙarfi, shin protein ne ko ƙarin kuzari? Mafi yawan gwaje‑gwajen ba su iya ware wannan bambancin.
Meta‑analysis ya gano cewa tasirin da suka fito da muhimmanci sun bayyana ne kawai a cikin gwaje‑gwajen da ba a daidaita kalori ba. Wannan ba ya nufin protein ba shi da amfani, amma hujjar ba za ta iya raba “sihirin protein” daga “ƙarin kalori da ke taimaka wa horo da dawowa” ba. Ga waɗanda ke cin abinci ƙasa da buƙata, wannan bayani na iya zama fa'ida – shake na iya zama hanya mai sauƙi don cike gibi na kuzari.
Whey vs. Sauran: Me Zamu Iya Ce?

- ‘Yan wasa da ke da matsala wajen cimma burin protein ko adadin kuzari daga abinci.
- Kowa da ke da nauyin horo da ya sa cin abinci ya zama ƙalubale. Anan ne ƙarin kuzari da protein ka iya zama tushen amfanin, wanda ya dace da korafin takardar.
