The keto diet follows an extreme breakdown of 70% to 75% fat, 20% protein, and 5% to 10% carbs. Some people will need to cut carbs to 20 grams a day to achieve ketosis.
Carbs are the enemy of the keto diet, but squash, cauliflower, cucumbers, tomatoes, and zucchini are all low enough to include in your daily meals.
This fatty fish is full of heart healthy omega-3s, and also qualifies for the keto plan due to its low carbs. Other approved fish include sardines, tuna, and shrimp.
The keto diet relies on fat for energy. Avocadoes and olive oil are all heart-healthy options, and coconut oil contains medium-chain triglycerides which convert easily into ketones.
Both foods are keto-friendly: Red meat is high in fat and protein and has virtually no carbs; a single egg has less than a gram of carbs and 6 grams of protein.
High-fat, low-carb nuts like almonds, pecans, and walnuts also contain fiber, which helps you feel full. (PS: Nuts have other perks, like lowering your risk of heart disease.)
