Keto Diet Calculator

The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate diet that shifts your body into ketosis. This nutritional strategy helps in creating a metabolic state, where the body fat becomes the primary source of fuel instead of glucose.

The keto diet has been scientifically proven to support weight loss, mental clarity, and stable energy levels. Besides weight loss the diet has been used in the management of seizures or epilepsy. Keto diet requires careful tracking of macronutrients to be effective (1).

Use our free Keto Diet Calculator to determine your ideal intake of net carbs, fat, and protein based on your age, weight, gender, activity level, and goals.

Whether you're looking to shed fat, manage blood sugar, or maintain energy, this tool provides the precision you need to succeed.

What are Ketones?

Ketones are produced in the liver as a by-product of fatty acid breakdown. Once formed, ketones travel through the bloodstream to various parts of the body, including the brain, where they can serve as an alternative energy source to glucose. There are three primary types of ketones: acetoacetate, beta-hydroxybutyrate (3HB), and acetone.

Glucose is not always readily available as an energy source, especially during fasting or prolonged exercise. In such conditions, the body relies on ketones for fuel. A ketogenic diet helps create this metabolic state, promoting fat metabolism and supporting weight loss.

Top Keto-Friendly Foods for a Ketogenic Diet

Medindia has provided you with food choices for planning your ketogenic diet. It also has listed food items that are required to be avoided when on this diet.

Keto-friendly food items include:

  • Healthy Oils: Ghee (clarified butter), butter, olive oil, coconut oil, and avocado oil.
  • Dairy: Unsweetened, full-fat dairy products like cheese (cheddar, mozzarella, blue cheese), heavy cream, and full-fat plain Greek yogurt.
  • Avocado: Rich in monounsaturated fats and fiber.

Protein Sources (Moderate Intake):

  • Meat and Poultry: Chicken (especially thighs), beef (sirloin steak, ground beef), pork (pork chops), lamb, bacon, sausages. Opt for grass-fed options when possible.
  • Seafood: Fatty fish like salmon, sardines, and mackerel (rich in omega-3s), as well as flounder, shrimp, crab, and lobster.
  • Eggs: They are a versatile source of protein and fat, especially the yolk.
  • Tofu: A plant-based protein option.

Low-Carb Vegetables (Non-Starchy):

Leafy Greens: Spinach, kale, lettuce (romaine, iceberg, butterhead), arugula, collard greens, Swiss chard, mustard greens.
  • Cruciferous Vegetables: Cauliflower (can be used as a rice substitute), broccoli, Brussels sprouts, and cabbage.
  • Other Low-Carb Vegetables: zucchini (can be spiralized into noodles), bell peppers, asparagus, mushrooms, cucumber, celery, radishes, green beans, and eggplant.

Nuts and Seeds (Healthy Fats and Fiber):

Almonds, walnuts, pecans, pumpkin seeds, chia seeds, flaxseeds, sunflower seeds.

Berries (Low-Carb Fruits in Moderation):

Strawberries, blackberries, raspberries. Blueberries can be included in smaller amounts due to slightly higher carb content.

Beverages:

  • Water
  • Unsweetened black coffee or tea
  • Masala chai (unsweetened, with keto-friendly milk alternatives if desired)
  • Chaach (buttermilk, in moderation)
  • Jal Jeera

Spices and Herbs:

Most spices and fresh herbs are naturally low in carbs and can be freely used to enhance the flavors in keto meals.

Foods to Avoid when on a Keto Diet

  • Carbs: High-Carb Grains and Starches: Rice, bread, pasta, oats, cereals, quinoa, corn.
  • Sugary Foods: Candy, cakes, pastries, ice cream, honey, jaggery, agave syrup, refined sugar.
  • Sweetened Beverages: Soda, fruit juices, sweetened teas, and sports drinks.
  • Starchy Vegetables: Potatoes, sweet potatoes, peas, beets, parsnips, yams.
  • Legumes: Beans, lentils, chickpeas.
  • Most fruits: Avoid high-sugar fruits like bananas, grapes, mangoes, pineapples, and most citrus fruits.
  • Processed Foods: Often contain hidden sugars, unhealthy fats, and excessive carbohydrates.
  • Alcohol: Many alcoholic beverages, particularly beer and sugary cocktails, are high in carbs. Opt for low-carb options like dry wine or spirits in moderation.

Important Considerations

Indian Keto Adaptation: Traditional Indian dishes can also be keto-friendly by incorporating paneer, chicken, fish, and low-carb vegetables. Additionally, they can also be cooked with ghee and coconut oil. Some of the dishes that are made using these ingredients include paneer bhurji, palak paneer, cauliflower rice, and coconut milk-based curries.

Electrolytes: Consuming low-carb foods might cause an electrolyte imbalance. Thus, an adequate intake of salt and other minerals is required to maintain electrolyte balance.

Top 10 Keto Diet FAQs

1. How does keto help with weight loss?

The keto diet promotes fat loss by reducing insulin levels and increasing fat-burning through ketosis. It reduces insulin spikes and increases fat metabolism. By doing this your body becomes more efficient at burning stored fat.

2. What is the basis of the ketogenic diet?

The ketogenic diet is based on shifting the body’s primary fuel source from glucose (sugar) to fat. By significantly reducing carbohydrate intake, the body enters a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. In the state of ketosis, ketone bodies serve as an alternate source of energy.

3. What is the ideal macro ratio for keto?

The keto macro calculator provides the exact grams of fat, protein, and carbs you need to maintain ketosis. The typical macronutrient ratio for a ketogenic diet is 70–75% fat, 20–25% protein, and 5–10% carbohydrates. Exact ratios can vary depending on your health goals and activity level.

4. How many carbs can I eat when on keto diet?

Most people following keto should limit themselves to 20–50 grams of net carbs per day to maintain ketosis and encourage burning of fat.

5. What is meant by ‘Net Carbs’ and how is it calculated?

Net carbs are the carbohydrates that your body actually digests by converting them into glucose. This intake of glucose can impact your blood sugar and insulin levels. Carbs are important to track on a ketogenic diet because consuming too many net carbs can kick you out of ketosis.
How to calculate Net Carbs:
Net Carbs = Total Carbohydrates − Fiber − Sugar Alcohols (if any)
Example:If a food label shows:
Total Carbohydrates = 20g
Dietary Fiber = 8g
Sugar Alcohols = 2g
Then:
Net Carbs = 20g − 8g − 2g = 10g net carbs
These 10 grams are what your body uses for energy from the 20 gms of carbs that you consume. This is the net carb you need to count toward your daily keto carb limit (typically 20–50g/day).

6. What happens if I eat too many carbs on keto?

Eating too many carbs can kick you out of ketosis, causing a return to glucose metabolism. This may lead to cravings, fatigue, and slower fat loss.

7. How much protein should I eat on keto?

Protein on a ketogenic diet should be moderate, not too high. A general guideline is to consume 0.6 to 1.0 grams of protein per pound of lean body mass per day. For example:
If you weigh 70 kg (154 lbs) and have a body fat percentage of 25%, your lean body mass is ~115 lbs.
Your protein intake should be between 69g and 115g per day depending on your goals (e.g., fat loss vs. muscle preservation).
Too much protein can raise insulin and interfere with ketosis, so it's important to stay within your calculated range.

8. Is this keto calculator suitable for beginners?

Absolutely! This calculator is designed to be beginner-friendly. It provides clear, customized guidance on how to balance your fat, protein, and carb intake to get started with keto confidently.

9. Is there any long term risks with Keto diet?

Long-term adherence to such low-carb diets has shown negative health effects. Some of the effects include decreased bone mineral density, cardiomyopathy, anemia, nephrolithiasis, and neuropathy (2)

10. Is the ketogenic diet safe long-term?

The keto diet is generally safe for most healthy adults. However, people with diabetes, liver disease, or kidney conditions should consult a healthcare provider before starting.
