A keto diet keeps carbohydrates very low, usually 20 to 50 g a day, and gets most of its calories from fat. You build meals on meat, fish, eggs, cheese, nuts and low-carb vegetables, and you leave out bread, pasta, rice, potatoes, beans and sugar.
Below is a keto meal plan for a week: breakfast, lunch and dinner for 7 days, the net carbs of each day, and the grocery list for the week sorted by aisle. If you are new to keto, the two short sections before the table explain the rules.
"Keto" is short for ketogenic. When you eat very few carbs, your body runs low on glucose and burns more fat. The liver turns part of that fat into ketones, which the body uses for fuel. This state is called ketosis.
To get there, most keto plans keep carbs under 50 g a day, and some go as low as 20 g. The Harvard T.H. Chan School of Public Health describes a classic split of 70 to 80% of calories from fat, 10 to 20% from protein and 5 to 10% from carbs.
Keto plans usually count net carbs: total carbs minus fiber. A cup of chopped broccoli has about 6 g of carbs, but 2 g of that is fiber, so it counts as about 4 g net.
Eat:
Avoid or keep very small:
It can, mostly because many people eat less when their meals are high in protein and fat. The first week often brings a fast drop on the scale, but much of that is water, not fat.
Over a year, the difference from a low-fat diet is small. A meta-analysis of 13 trials with at least 12 months of follow-up found that people on a very-low-carb ketogenic diet lost on average 0.91 kg (2 lb) more than people on a low-fat diet (Bueno et al., British Journal of Nutrition, 2013 ). The same study found a small rise in LDL cholesterol on keto. So choose the diet you can follow for months. On any diet, you need to eat fewer calories than you burn. Our calorie calculator gives you a starting number.
In the first days, some people get headaches, tiredness, low mood, constipation or "brain fog". This is often called the "keto flu". It usually passes in a few days to a few weeks. Drink enough water and add enough salt to your food.
Keto is not for everyone. If you have type 1 diabetes, take medicine for diabetes or blood pressure, have kidney or liver disease, are pregnant or breastfeeding, or are under 18, talk to your doctor before you start.
We made this week in MenuMagic with the Keto diet turned on and breakfast, lunch and dinner planned. We did not change the meals. The net carbs come from the recipes the app wrote for each meal: total carbs minus fiber, per person, with sweeteners such as erythritol and stevia counted as zero.
| Day | Breakfast | Lunch | Dinner | Net carbs |
|---|---|---|---|---|
| Monday | Spinach and goat cheese omelet | Grilled chicken Caesar salad with Parmesan crisps | Pan-seared salmon with roasted asparagus | about 13 g |
| Tuesday | Chia seed pudding with crushed walnuts | Avocado tuna salad collard wraps | Bacon-wrapped pork tenderloin with sautéed green beans | about 17 g |
| Wednesday | Greek yogurt with toasted pecans and cinnamon | Cauliflower fried rice with shrimp | Baked herb-crusted cod with roasted broccoli | about 28 g |
| Thursday | Mushroom and Swiss scramble | Cobb salad with hard-boiled egg and ranch dressing | Beef stir-fry with bok choy and mushrooms | about 18 g |
| Friday | Almond flour blueberry mug muffin | Turkey and cheddar lettuce wraps with Dijon mayo | Pan-roasted ribeye steak with garlic butter mushrooms | about 14 g |
| Saturday | Avocado halves stuffed with bacon and baked eggs | Keto cheeseburger bowl with dill pickles | Garlic butter baked halibut with sautéed spinach | about 12 g |
| Sunday | Cottage cheese with sliced almonds and hemp hearts | Chicken and roasted poblano stuffed bell peppers | Braised beef short ribs with mashed cauliflower | about 44 g |
Six of the seven days stay under 30 g of net carbs. Sunday is higher because the braise cooks with onion, carrot, tomato paste and red wine. To keep Sunday under 30 g, leave out the carrot and use half the onion, or split the short ribs into four portions and keep two for another day.
In this week, about 60 to 75% of the calories come from fat and 20 to 35% from protein. That is a little more protein than classic keto. Extra protein helps you keep muscle while you lose weight.
A few notes on the week:
Quantities are for two adults. Check your pantry first: you probably have the oil, spices and some of the condiments already. For the method behind a list like this, see how to make a grocery list from a meal plan .
Fruit and vegetables
Meat
Fish and seafood
Dairy and eggs
Nuts, seeds and baking
Condiments and canned goods
Pantry (check first)
The week above is one example. Next week you need 21 new meals and a new grocery list. MenuMagic has a keto diet setting, so each new week follows the same rules without extra work:
Allergies and dislikes from your settings still apply, for example no shellfish or no mushrooms. If a meal does not fit, or you don't like it, tap it while editing the plan and choose Regenerate; the new meal is keto too. For one keto dinner made from what is in your fridge, try the recipe generator .
With Premium, each meal comes with its full recipe: ingredients, steps, calories and macros, including carbs and fiber, so you can check your net carbs. If you plan for one person, the planner picks dishes that fit your calorie goal and sizes each recipe to it. In the shopping list, Generate list turns the week into a list with quantities, sorted by aisle and shared with everyone in your household. The Diary logs your planned meals with their calories and macros in one tap; our guide on how to track macros for beginners explains the numbers.
Meal names in the plan and the diet settings are free. Full recipes, calorie-sized portions, macros, the automatic shopping list and one-tap logging need Premium.

Meat, poultry, fish, seafood, eggs, butter, cheese, cream, plain full-fat yogurt, avocado, olive oil, nuts, seeds and low-carb vegetables such as spinach, lettuce, broccoli, cauliflower, zucchini, asparagus and mushrooms. Small amounts of berries also fit. Bread, pasta, rice, potatoes, beans, sugar and most fruit do not.
Most keto plans keep carbs under 50 g a day, and stricter ones go down to 20 g. They usually count net carbs, which are total carbs minus fiber. The sample week in this article has about 12 to 28 g of net carbs on six days, and 44 g on Sunday.
It can, because high-protein, high-fat meals are filling and many people eat less. Much of the fast loss in the first week is water. In a meta-analysis of 13 trials of a year or more, people on keto lost on average 0.91 kg (2 lb) more than people on a low-fat diet. You still need to eat fewer calories than you burn.
Talk to your doctor first if you have type 1 diabetes, take medicine for diabetes or blood pressure, have kidney or liver disease, are pregnant or breastfeeding, or are under 18. Keto can lower blood sugar and blood pressure quickly, so some medicines may need a new dose.
