Although fat makes up at least 70% of the calories on a ketogenic diet, not all sources of fat are good for your health.
Trans fats may be indicated on an ingredient label under the names “partially hydrogenated oils” or “shortening.” It’s best to avoid foods that contain these ingredients as much as possible.
Artificially produced trans fats are known for significantly increasing heart disease risk and should be avoided, regardless of the type of diet you’re following.
The United States among several other countries has banned or restricted the use of artificial trans fats. However, in some regions, trans-fat-containing products manufactured before June 18, 2018 may be distributed until January 2020, or 2021 in some cases.
What’s more, if a food provides less than 0.5 grams of trans fats per serving, it’s labeled as having 0 grams of trans fats.
