The ketogenic diet has become quite popular recently.
Studies have found that this very low-carb, high-fat diet is effective for weight loss, diabetes and epilepsy.
There’s also early evidence to show that it may be beneficial for certain cancers, Alzheimer’s disease and other diseases, too.
A ketogenic diet typically limits carbs to 20–50 grams per day. While this may seem challenging, many nutritious foods can easily fit into this way of eating.
Here are 16 healthy foods to eat on a ketogenic diet.
Fish and shellfish are very keto-friendly foods. Salmon and other fish are rich in B vitamins, potassium and selenium, yet virtually carb-free.
However, the carbs in different types of shellfish vary. For instance, while shrimp and most crabs contain no carbs, other types of shellfish do.
While these shellfish can still be included on a ketogenic diet, it’s important to account for these carbs when you’re trying to stay within a narrow range.
Here are the carb counts for 3.5-ounce (100-gram) servings of some popular types of shellfish:
Clams: 5 grams
Mussels: 7 grams
Octopus: 4 grams
Oysters: 4 grams
Squid: 3 grams
Salmon, sardines, mackerel and other fatty fish are very high in omega-3 fats, which have been found to lower insulin levels and increase insulin sensitivity in overweight and obese people.
In addition, frequent fish intake has been linked to a decreased risk of disease and improved mental health.
Aim to consume at least two servings of seafood weekly.
Many types of seafood are carb-free or very low in carbs. Fish and shellfish are also good sources of vitamins, minerals and omega-3s.
