Keto Meal Planner

How to Plan a Keto Meal Week

Keto meal planning succeeds or fails on one number: net carbs. Keep daily net carbs under 20 grams and your liver starts converting fatty acids into ketones, shifting your body's primary fuel from glucose to fat. Planning meals in advance is the most reliable way to hit that target every day without guesswork.

Net Carbs = Total Carbs − Fiber

Dietary fiber passes through the digestive tract unabsorbed and does not raise blood glucose. A food like avocado has 12g total carbs but 10g fiber, giving it just 2g net carbs — making it one of the best keto foods available. Always check fiber content when evaluating a food for keto.

The 75 / 20 / 5 Macro Rule

A standard ketogenic diet derives roughly 75% of calories from fat, 20% from protein, and 5% from carbohydrates. Fat is not just permitted on keto — it is the primary fuel source. Foods like ribeye steak, salmon, avocado, coconut oil, butter, and heavy cream form the backbone of a well-formulated keto diet. Getting enough fat prevents the energy crashes and cravings that derail beginners.

Protein matters too. Too little leads to muscle loss; too much can trigger gluconeogenesis — a process where excess protein converts to glucose and potentially knocks you out of ketosis. Moderate protein (0.6–1.0g per pound of lean body mass) is the sweet spot. Use an app like Caloria to track both fat and protein alongside net carbs.

Best Keto Foods to Stock Weekly

Fatty proteins. Ribeye, salmon, chicken thighs (skin-on), ground beef (80/20), bacon, and eggs. These hit both your fat and protein targets simultaneously.
Low-carb vegetables. Spinach, kale, broccoli, zucchini, cauliflower, asparagus, and cucumbers. These are nutrient-dense while contributing minimal net carbs.
Healthy fats. Avocado, olive oil, coconut oil, butter, and MCT oil. These round out your fat macros and support sustained energy throughout the day.
Keto snacks. Macadamia nuts, pork rinds, hard cheeses, and olives. Having these on hand prevents carb-heavy snacking when hunger strikes between meals.

Common Keto Mistakes to Avoid

Tracking total carbs instead of net carbs. High-fiber foods like avocado and broccoli look high-carb until you subtract fiber. Always use net carbs for your daily limit.
Not eating enough fat. Many beginners under-eat fat because they have been conditioned to fear it. Without adequate fat, low-carb diets lead to fatigue and hunger rather than ketosis.
Forgetting hidden carbs. Sauces, condiments, dressings, and processed snacks often contain surprising amounts of sugar and starch. Read labels carefully.
Skipping electrolytes. Reduced insulin on keto causes your kidneys to excrete more sodium, potassium, and magnesium. Supplement or eat electrolyte-rich foods (bone broth, leafy greens, nuts) to avoid keto flu.

Frequently Asked Questions

How many carbs can I eat on keto?

The standard ketogenic diet limits net carbs to 20–50 grams per day. Net carbs are calculated by subtracting fiber (and sugar alcohols) from total carbohydrates. This planner uses a strict 20g net carb daily limit, which is the most effective threshold for achieving and maintaining ketosis in most people.

What is the ideal keto macro ratio?

The classic ketogenic macro split is 75% fat, 20% protein, and 5% carbohydrates by calories. Fat provides the bulk of energy to replace glucose, protein supports muscle maintenance, and carbs are kept extremely low to trigger ketosis. The ratio bar in each day view shows how close your meals are to these targets.

What are net carbs and why do they matter on keto?

Net carbs equal total carbohydrates minus dietary fiber (and any sugar alcohols). Fiber is not digested and does not raise blood sugar or impact ketosis. Because of this, high-fiber foods like avocado, leafy greens, and nuts are keto-friendly even though their total carb count looks higher. Always track net carbs, not total carbs, on a ketogenic diet.

How long does it take to enter ketosis?

Most people enter ketosis within 2–4 days of consistently staying under 20g net carbs per day, depending on activity level and individual metabolism. Depleting glycogen stores through exercise can speed the process. Symptoms of early ketosis (the "keto flu") include fatigue, headaches, and brain fog, which typically resolve within a week as your body adapts to using fat for fuel.

Can I do keto as a vegetarian?

Yes, though it requires more planning. Vegetarian keto protein sources include eggs, full-fat cheese, cottage cheese, Greek yogurt, tofu, tempeh, and nuts. Fat sources include avocado, olive oil, coconut oil, and nut butters. The challenge is avoiding high-carb plant proteins like beans and lentils. Focus on non-starchy vegetables (spinach, broccoli, zucchini, cauliflower) for your carb allowance.

Is this keto meal planner free?

Yes, 100% free with no sign-up required. You can customize a full week of keto meals, track net carbs and macro ratios for each day, and use the keto swap guide — all in your browser without creating an account.
