How to Use Cronometer for Your Keto Diet

Starting a keto diet can feel overwhelming at first, especially when you’re trying to figure out how many carbs you’ve eaten or if you’re hitting your fat goals. That’s where Cronometer comes in. It’s a free app that helps you keep track of your food, macros, and nutrients in a super simple way. In this guide, we’ll show you how to use Cronometer to stay on track with your keto lifestyle without the guesswork.

Keto Explained: How It Works and Who It Helps

The ketogenic diet, or keto for short, is a low-carb, high-fat eating plan designed to help your body switch from using glucose (sugar) as its main fuel source to burning fat instead. This process is called ketosis, and it can offer a range of benefits, including fat loss, improved energy, better focus, and stable blood sugar levels.

Keto works by drastically cutting carbohydrate intake (usually to under 50 grams per day), eating moderate protein, and significantly increasing fat intake. This shift encourages your body to produce ketones in the liver, which it then uses for energy.

People choose keto for many different reasons:

• Weight loss: Keto can help reduce hunger and increase fat burning.
• Metabolic health: It may improve insulin sensitivity and blood sugar control.
• Mental clarity: Some find they think more clearly and avoid energy crashes.
• Therapeutic use: Originally developed for epilepsy, keto is now also being explored for conditions like PCOS, Type 2 diabetes, and neurological disorders.

Keto isn’t for everyone. It can take time for your body to adapt, and some people may experience temporary side effects like fatigue, irritability, or digestive changes during the adjustment period. If you’re pregnant, breastfeeding, or have underlying health issues, it’s best to consult a healthcare professional first.

Why Cronometer Works So Well for Keto

Most food tracking apps focus mainly on calories, but that’s not enough for a successful keto diet. Keto isn’t just about eating fewer calories – it’s about eating the right balance of fat, protein, and carbs to shift your body into ketosis.

Cronometer stands out because it tracks micronutrients, net carbs, and gives you customizable macro goals. Plus, it uses high-quality food databases like NCCDB and USDA, which means more accurate tracking. And for anyone serious about keto, precision really matters.

Step 1. Setting Up Your Keto Targets

Cronometer has a built-in Keto Calculator that does the heavy lifting. Instead of asking you to enter percentages manually, it calculates your ideal macro targets based on your body stats and goals.

Here’s how to set it up:

On Web:

• Go to “More” > “Targets + Profile”
• Under “Macronutrient Targets,” select “Keto Calculator”

On Mobile:

• Go to “More” > “Targets” > “Macro & Energy Targets”
• Scroll down and choose “Keto” under “Macro Targets”

From there, you can choose one of four preset keto styles.

Keto Program Options in Cronometer

Program Type	Best For	Carb Limit	Protein Goal	Notes
Rigorous	Therapeutic use (e.g. epilepsy) or very sensitive users	Very low	1.0g/kg LBM	Athletic bonus disabled
Moderate	General weight loss or health	Low	1.5g/kg LBM	Athletic bonus enabled
Relaxed	Active users who tolerate more carbs	Moderate	1.5g/kg LBM	More flexible, bonus enabled
Custom	Personalized approach	User-defined	User-defined	Requires manual input or professional guidance

Step 2. Understanding How Cronometer Calculates Macros

What makes Cronometer’s Keto Calculator especially helpful is that it calculates your targets dynamically based on your lean body mass (LBM). This means you’re not just working with general percentages – your protein intake is calculated in grams per kilogram of LBM.

• Rigorous setting: 1.0g of protein per kg of LBM
• Moderate setting: 1.5g of protein per kg of LBM

To get the most accurate results, you should keep your body fat percentage updated. You can enter it manually if you know it, or estimate it using guides and charts.

Carbs are set based on the keto program you choose. And fat fills in the remaining calories after your protein and carb needs are met. If you have a weight loss goal, the app will automatically adjust fat down to create a calorie deficit.

If you exercise, the Athletic Bonus kicks in and gives you an extra 1g of carbs per 50 kcal burned. This is automatically enabled for Moderate and Relaxed keto settings, and disabled for Rigorous.

Step 3. Tracking Food Accurately

One of the biggest reasons people stall on keto is underestimating how much they’re actually eating. That’s why accuracy matters, and it’s where Cronometer really shines.

When logging food:

• Use entries from the NCCDB or USDA databases for best accuracy
• Avoid crowd-sourced entries unless you double-check them
• Use a food scale to weigh portions instead of guessing

Cronometer calculates net carbs automatically (total carbs minus fiber and sugar alcohols). If you consume sugar alcohols like erythritol or xylitol, make sure your entries reflect how they should be counted. Some people create custom foods to be extra precise.

Step 4. Keeping Track of Ketosis Progress

Keto isn’t just about logging food – it’s about understanding whether your body is actually in ketosis. Cronometer allows you to sync with devices like Keto-Mojo, so your blood ketone readings can be imported directly into your account.

If you’re a Gold subscriber, you also get access to the Ketogenic Nutrition Score. This feature gives you a score based on how well you’re hitting key keto metrics:

• Staying under net carb limit
• Hitting protein target without going over
• Getting enough fat
• Meeting important micronutrient needs (sodium, magnesium, potassium, water, fiber)

It’s a solid way to quickly see how dialed in your diet is.

Extra Tips for Using Cronometer on Keto

1. Log food right away: Don’t wait until the end of the day. Logging meals as you go helps you stay on top of your daily goals and prevents accidentally going over your carb or protein limits.
2. Use favorites and custom meals: If you eat the same breakfast or snack most days, save it to your favorites or create a custom meal. It saves time and helps you track consistently without getting overwhelmed.
3. Plan ahead: Pre-log your meals in the morning or the night before, especially if you know what you’re going to eat. This gives you a clear picture of your macros in advance and lets you make better choices throughout the day.
4. Track water: Dehydration is common on keto. Use Cronometer to track your water intake and make sure you’re staying properly hydrated. This also helps with electrolyte balance and avoiding keto flu symptoms.
5. Review data regularly: Once a week, look at your trends. Are your net carbs creeping up? Are you meeting your fiber or potassium targets? A quick review can help you spot issues before they impact your progress.

Do You Need Cronometer Gold for Keto?

The free version of Cronometer gives you everything you need to start and maintain a successful keto diet. You can set up your keto macros, log food with high accuracy, and track all essential nutrients and net carbs without paying a dime. For many people, that’s more than enough.

However, Cronometer Gold adds some extra tools that can make keto tracking more convenient and insightful:

• Nutrition Score including the Ketogenic Score, which tells you how well you’re meeting your key keto goals like net carbs, fat intake, electrolytes, and hydration.
• Custom charts and reports so you can track trends over time and see how your diet is really affecting your progress.
• Fasting timer, diary groups, and ad-free experience, all of which can improve the usability of the app and make it easier to focus.
• Priority support and more advanced customization options for those who like digging into data.

If you’re serious about long-term keto or love having more detailed feedback, Gold is likely worth it. But rest assured – even with just the free version, you can do keto well, track accurately, and see real results.

Recipe Nutrition Made Simple with ReciMe

While there are many apps good at tracking every bite with scientific precision, they are not built for home cooks who rely on recipes. That’s where we come in.

We built ReciMe because we saw how many home cooks on keto were stuck copying and pasting ingredients into generic trackers. ReciMe is different – it pulls the nutrition data straight from your recipes, so you know the exact macros before you even heat the pan.

Why It Matters for Keto

• Automatic nutrition from any recipe: Import a TikTok reel, Instagram post, or your own notes and we instantly calculate calories, net carbs, protein, and fat. No more manual entry.
• One‑click scaling: Cooking for two instead of four? Adjust servings and we recalculate macros on the spot so your carb count stays precise.
• Smart grocery lists: With a tap, every ingredient lands in an aisle‑ordered list. Less time shopping means more time meal‑prepping.
• Drag‑and‑drop meal planner: Plan a week of keto dinners and watch your macro totals update in real time. It’s like having a dietitian built into your calendar.
• Every device, everywhere: iOS, Android, and a Chrome extension for lightning‑fast imports.

We designed ReciMe for people who love to cook, want tight macro control, and prefer real food over packaged bars. If that sounds like you, give it a try – your keto kitchen just got a lot smarter.

Just try it – you’ll love it:
