The ketogenic, or keto, diet can be a good way to lose weight and reduce body fat. However, the strict macronutrient ratios can make it difficult to know which foods to choose and may require careful planning for grocery shopping.
This article looks at what to include in a keto grocery list and provides recipe ideas for breakfast, lunch, and dinner.
It also looks at the side effects of the diet and how to prevent them.
A keto diet is a low carbohydrate diet that some people use for its potential health benefits, such as promoting weight loss.
According to one
- 55–60% fat
- 30–35% protein
- 5–10% carbohydrates
On a 2,000 calorie per day diet, this means limiting carbohydrates to 20–50 grams (g) per day.
According to the same 2020 article, a keto diet should limit protein intake to less than 1 g per pound (lb) of body weight (or 1.5 g per lb of body weight for people who do heavy weight training).
A keto diet puts the body in a state of ketosis. This occurs when the body switches from burning carbohydrates as fuel to burning stored fats instead. Some keto diets aim to facilitate weight loss by creating a metabolic state where the body converts fat stores into energy.
The following are some keto-friendly foods to add to a grocery list.
A person should include non-starchy vegetables in a keto diet to provide essential nutrients such as vitamins, minerals, and fiber.
Such vegetables include:
- green beans
Many fruits have a sugar content that is too high to be keto-friendly. However, a person can count their fruit intake as part of their carbohydrate allowance for the day and choose lower sugar fruits, such as berries, coconut, and citrus fruits.
People can vary their protein sources so that they get variety in the keto diet. Many protein sources, such as meat and dairy, also contain fat, so people can account for this when tracking their macronutrients.
The following are some protein foods to include:
- chicken and turkey
- red meat, such as beef or lamb
- unsweetened dairy products, such as Greek yogurt, cheese, and cream
- fish and shellfish
- tofu, tempeh, and seitan
One of the criticisms of the keto diet is that a person may consume too much saturated fat. The Dietary Guidelines for Americans recommend limiting calories from saturated fats to less than
More healthful unsaturated fats sources include:
- olive oil
- avocado and avocado oil
- fatty fish, such as sardines and salmon
- nuts and nut butter
- sesame oil
- hemp seed oil
Coconut oil is a saturated fat that people can include, and many people also use medium chain triglyceride oil.
People should always stay adequately hydrated. This can also help prevent the side effects of the keto diet.
Plain water is a simple, healthful option, but other ideas for beverages to include are:
- water with added mint leaves and citrus slices
- herbal teas
- occasional zero sugar sodas
- unsweetened soy and almond milk
- bone broth
People can stock up on the following useful pantry items for a keto diet:
- coconut cream
- almond flour
- soy sauce or tamari
- liquid aminos or coconut aminos
- fish sauce
- dried herbs and spices
- cocoa powder
- garlic powder and onion powder
There are many online resources that allow people to look up keto recipe ideas. For example, keto diet apps may be a good option, as they include many recipe ideas along with their macronutrient content.
One keto diet app suggests the following recipe ideas for breakfast, lunch, and dinner:

People may find keto diets challenging initially, and they may have food cravings and hunger pangs. However, this usually subsides with time.
There are also some short-term side effects of keto diets, which are sometimes collectively referred to as keto flu.
Symptoms can include:
- difficulty exercising
People should ensure that they stay hydrated with fluids and electrolytes to help prevent some of these side effects.
Eating fiber-rich and magnesium-rich foods — such as dark leafy green vegetables, cocoa, and pumpkin seeds — can help prevent constipation.
Keto diets may result in a buildup of acids, known as ketones, in the blood. Small amounts of ketones in the blood indicate that the body is breaking down fat. However, high levels of ketones can poison the body, leading to a condition known as ketoacidosis. Therefore, it is important to monitor kidney function while following a keto diet long term.
Keto diets may not be suitable for people with health issues such as diabetes and those who are taking certain medications. A person should check with their doctor first.
If a person transitions back to a standard diet, they should do so gradually to avoid rebound high blood sugars and weight gain.

After a person has confirmed that a keto diet is suitable for them, they can start by planning what they will eat and making a grocery list.
Varying the meals can help make the menu more interesting, and this can help someone stick to a diet plan.
People should be careful to avoid too much saturated fat, and they should make sure that they include a variety of vegetables. Stocking up on pantry staples and using a keto recipe app are ideas to help prepare future meals.
