OPTIFAST® VLCD™ is formulated to contain adequate high quality protein in sufficient quantities for nitrogen sparing and to preserve lean body mass. Protein requirements for obesity/weight loss have been proposed at 0.75-1.0g/kg Adjusted Ideal Body Weight (Adj IBW) /day.

Consumption of 3 sachets or bars per day of OPTIFAST® VLCD™ meets the protein requirements for obesity/ weight loss for females. For males and for individuals requiring a higher protein intake than 0.75g/kg Adj IBW per day, they may need an additional OPTIFAST® VLCD™ product or an additional serve of protein to meet protein requirements. One serve of protein is equivalent to 65-100g meat, 2 eggs or 130g fish and is usually added to the evening vegetables. It should be noted that for intakes greater than 3 sachets per day of OPTIFAST® VLCD™, calorie intake may increase higher than 800 calories.
