The keto diet is a way to do this. It’s low in carbs and high in fat. By cutting way back on carbs, your body might enter a state called ketosis. In ketosis, your body starts burning fat for energy instead of carbs, which can help you lose weight.
If you’re talking about dieting or weight loss, you’ll likely hear about the keto diet. It’s become one of the most popular ways for people around the world to lose weight and improve their health.
If you’re considering the keto diet and your healthcare professional has approved, use this article to learn what foods to eat and what to avoid on a keto diet.
Basics of the ketogenic diet
The keto diet is very low in carbs, high in fat, and moderate in protein. You’ll need to monitor your carb intake closely.
Here’s a rough breakdown of the calories you’ll consume on the keto diet:
- Carbs: 5–10%
- Fats: 70–75%
- Protein: 15–20%
This reduction in carbs forces your body to use fats for energy instead of glucose, a process called ketosis. In ketosis, your body uses ketones—molecules made in the liver from fats—as an alternative fuel source. Additionally, keto diets can help reduce hunger and increase feelings of fullness, which is beneficial for weight loss.
Research shows that ketogenic diets can promote weight loss, though they might not be more effective than other weight-loss diets.
Meal plan for a ketogenic diet
Switching to a ketogenic diet might seem overwhelming, but it doesn’t have to be hard. Focus on reducing carbs while increasing the fat and protein in your meals and snacks. Incorporating a consistent gym routine can also enhance your overall results. Online tools and calculators can help.
To reach and stay in ketosis, you must restrict carbs. Some people may achieve ketosis by eating just 20 grams of carbs per day, while others might do it with a higher intake.
Generally, the lower your carbohydrate intake, the easier it is to reach and maintain ketosis. This is why sticking to keto-friendly foods and avoiding high-carb items, along with following a regular gym routine, is the best way to successfully lose weight on a ketogenic diet.
Keto-friendly foods
When following a ketogenic diet, focus your meals and snacks around these foods:
- Eggs: Pastured, organic, or conventional
- Poultry: Chicken and turkey
- Fatty fish: Salmon, herring, and mackerel
- Meat: Bison, organ meats, hog, venison, and beef
- Full-fat dairy: Unsweetened yogurt, butter, and cream (check labels for carbs)
- Full-fat cheeses: Include cream, goat, mozzarella, brie, and cheddar.
- Nuts and seeds: peanuts, flaxseeds, pumpkin seeds, almonds, walnuts, and macadamia nuts
- Nut butter: No-sugar-added peanut, almond, and cashew butters
- Healthy oils: Olive oil, avocado oil, and sesame oil
- Avocados: You may add whole avocados to practically any meal or snack.
- Non-starchy vegetables: Greens, broccoli, tomatoes, mushrooms, and peppers
- Condiments: Include salt, pepper, vinegar, lemon juice, fresh herbs, and spices.
Foods to limit
To follow a keto diet effectively, it’s advisable to minimize high-carb foods. Here’s what to limit:
- Bread and baked goods: like white bread, whole wheat bread, crackers, cookies, doughnuts, and rolls.
- Sweets and sugary foods: such as sugar, ice cream, candy, maple syrup, honey, agave syrup, and coconut sugar.
- Sweetened beverages: like soda, juice, sweetened teas, and sports drinks.
- Pasta: including spaghetti and other noodles.
- Grains and grain products: Such as wheat, rice, oats, breakfast cereals, and tortillas.
- Starchy vegetables: like potatoes, sweet potatoes, butternut squash, corn, peas, and pumpkin.

- Fruits: like citrus, grapes, bananas, and pineapple.
- High-carb sauces: like barbecue sauce, ketchup, honey mustard, sugary salad dressings, and dipping sauces.
- Certain alcoholic beverages: like beer and sugary mixed drinks.
While it’s important to restrict carbs, you can include small amounts while monitoring intake. For example, low-glycemic fruits like berries can be enjoyed in moderation, ensuring they fit within your keto-friendly macronutrient goals (carbs, protein, and fat).
Opt for whole foods over processed options, and avoid trans fats whenever possible.
Keto-friendly drinks
Sugar is present in many drinks, including juice, soda, iced tea, and coffee drinks. If you’re on a ketogenic diet, it’s important to limit or avoid high-carb drinks, just like high-carb foods.
Sugary drinks have been linked to various health issues, such as obesity and an increased risk of type 2 diabetes.
For those on the keto diet, there are plenty of tasty sugar-free options, including:
- Water: The best choice for hydration, it should be consumed throughout the day.
- Sparkling Water: A great soda replacement.
- Unsweetened Coffee: Add flavor with heavy cream.
- Unsweetened Green Tea: is delicious and may provide many health benefits.
To add extra flavor to your water, try different keto-friendly combinations. For instance, adding fresh mint and a lemon peel to your water bottle can make hydration enjoyable.
While alcohol should be limited, an occasional low-carb drink like vodka or tequila mixed with soda water is acceptable on the keto diet.

keto diet Benefits
Some research suggests that following a low-carb, high-fat diet can help with weight loss and improve blood sugar control in people with type 2 diabetes. The keto diet might also protect the brain and enhance cognitive function in people with Alzheimer’s disease, although more studies are needed to confirm this.
Risks and drawbacks
While the keto diet has some benefits, it may not be suitable for long-term use due to several risks and drawbacks.
- Keto Flu: When starting the keto diet, you might experience symptoms like the flu as your body adapts to a low-carb diet. This transition, called ketosis, can also cause leg cramps, digestive issues, and bad breath. Although ketosis is generally safe, it may not be suitable for everyone.
- Weight Regain: Although the keto diet can help with weight loss, stopping the diet often leads to regaining the lost weight.
- Not for Everyone: The keto diet isn’t recommended for people with kidney failure, liver disease, or type 1 diabetes, as it can lead to serious health issues like ketoacidosis. Always consult your healthcare provider before starting the keto diet.
- Cholesterol Impact: The keto diet is usually high in saturated and trans fats, which can increase LDL (“bad”) cholesterol and raise the risk of heart disease and stroke for some people.
- Fiber and Vitamins: The diet is often low in vegetables, grains, and legumes, which can lead to deficiencies in fiber and B vitamins, essential for maintaining good health.
- Restrictive: The keto diet is highly restrictive and requires careful planning, making it difficult to sustain. Its lack of variety can lead to nutritional deficiencies and boredom, and it can complicate social situations, such as eating out.
- Pregnancy and Nursing: The keto diet may not be safe for pregnant or nursing individuals.
For these reasons, it’s important to consult a health professional before trying the keto diet.
