How to Use the High-Protein Low-Carb Grocery Calculator
Starting a high-protein, low-carb diet but not sure how much of each ingredient to buy for the week — or what it'll cost? This calculator helps. Just enter your daily protein target and how many days per week you'll follow the diet, and it splits that target evenly across the three staple protein sources — chicken breast, eggs, and tofu — to show you the amount needed, the estimated cost, and the estimated calories.
Splitting across three ingredients keeps things varied since each has different cooking uses and nutrient profiles, so you're not stuck eating the same thing every day. The math uses 31g of protein per 100g of chicken breast, 6g per egg (60g), and 8g per 100g of tofu, with average US prices of $1.32 per 100g of chicken breast, $0.25 per egg, and $0.60 per 100g of tofu.
The estimated total cost is meant to help you budget before you actually go shopping. Prices vary by region and season, so it's worth checking your local store's current prices alongside this estimate before you buy.
