Eksperimentel: Lean (≥90%) Grass-Fed Beef
The quantity of beef will be adjusted or normalized based on their individual energy requirements. The specified amount will be 4 oz. per day or 28 ounces per week for participants with an energy requirement of 2000 kcal. Participants will consume meals for six weeks. |
