Keto Macro Calculator

How to Use Keto Macro Calculator

1. Enter your daily calories. Input the total calories you plan to eat on keto, typically from a TDEE calculator adjusted for a deficit or maintenance.
2. Set your net carbs limit. The default is 25 g, which is standard for nutritional ketosis. You can adjust it between 10 and 50 g.
3. Adjust protein and fat percentages. The tool auto‑calculates the carbs percentage from your net‑carb grams. Tweak the protein and fat sliders to dial in your ideal ratio, typically around 25% protein and 70% fat.
4. Click Calculate. You’ll see the grams of fat, protein and net carbs per day, along with a list of keto‑friendly food tips.

Benefits of Keto Macro Calculator

• Net‑carb driven calculation ensures you stay within ketogenic thresholds, not just a generic low‑carb estimate.
• Auto‑updates the carb percentage as you adjust the net‑carb limit, so the three macros always add up to 100%.
• Visual sliders for protein and fat help you quickly try different splits without manual math.
• No data leaves your device – your diet plan remains completely private.

Frequently Asked Questions

What is the difference between total carbs and net carbs?

Net carbs are total carbohydrates minus fibre and sugar alcohols, which have minimal impact on blood sugar. For keto, only net carbs matter because they affect ketosis.

How much protein should I eat on keto?

Too much protein can theoretically be converted to glucose (gluconeogenesis), so most keto plans recommend 20–25% of calories from protein. The default setting reflects that.

Can I use this calculator for a standard low‑carb diet instead of keto?

Yes, just raise the net‑carb limit to 50 g or more. The tool will adjust accordingly, making it flexible for both keto and moderate low‑carb approaches.

Is Keto Macro Calculator free and private?

Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
