You need one serving per day as a dedicated meal (3 servings total for the 3 days), or two servings per day (6 servings total) if you want these bowls to cover both lunch and dinner.
At 180 pounds, a standard daily target for an active adult is roughly 130 to 160 grams of protein and 2,200 to 2,500 calories.
Since each bowl delivers 520 calories and 44 grams of protein, a single serving easily locks down about a third of your daily protein needs in one sitting.
If you plan to rely on them for two of your daily meals, simply double the prep batch to 6 servings so you can eat two bowls a day.
