~36sWarning
Starting a ketogenic diet while taking diabetes medications, blood pressure medications, or diuretics can cause blood sugar or blood pressure to drop quickly. Always consult your doctor before beginning a very low-carb diet if you take any prescription medications.
Log a meal and check the net carbs
~32sQuick Tip
Many grocery store items now print net carbs directly on the label. For items that do not, Carb Manager calculates it automatically: total carbs minus fiber minus sugar alcohols.

Carb Manager is a food tracking app built specifically for people following a low-carbohydrate or ketogenic diet. While most tracking apps show total carbohydrates, Carb Manager focuses on net carbs — total carbohydrates minus dietary fiber and sugar alcohols. Net carbs are what most low-carb and keto dieters care about because fiber and certain sugar alcohols do not raise blood sugar the way regular carbs do.
A ketogenic diet typically limits net carbs to about 20 to 50 grams per day, depending on the individual. This very low carbohydrate intake causes the body to shift from burning glucose for fuel to burning fat — a state called ketosis. Many people find this approach helpful for weight loss, blood sugar management, or reducing inflammation. However, it is a significant change in eating habits and affects how medications work, so talking to your doctor before starting is important.
Carb Manager has one of the largest databases of keto-friendly and low-carb food entries, including restaurant menu items and specialty low-carb products. When you log a food, the app prominently displays the net carb count in large text at the top of the screen rather than burying it.
The app also helps you plan meals. The meal planner section suggests low-carb recipes based on your daily carb target, and the grocery list feature lets you add recipe ingredients with a single tap. If you use a continuous glucose monitor like a Dexcom, Carb Manager can display your glucose readings alongside your food log so you can see how specific meals affect your blood sugar.
The free version covers all the basics. Premium features include more advanced meal planning and deeper analytics.
