Keto Means

The bottom line Overall, shorter and lower-heat cooking methods cause less cholesterol oxidation and help retain most of the egg's nutrients. For this reason, poached and boiled (either hard or soft) eggs may be the healthiest to eat. These cooking methods also don't add any unnecessary calories.
Generally, you'll need to adhere to a caloric deficit of around 500 calories per day. At this rate, you should start to see noticeable weight loss...

Read More »High-heat cooking may damage other nutrients Although cooking eggs makes some nutrients more digestible, it can damage others. This isn’t unusual. Cooking most foods will result in a reduction of some nutrients, particularly if they’re cooked at high temperatures for a long period of time. Studies have examined this phenomenon in eggs. One study found that cooking eggs reduced their vitamin A content by around 17-20% ( 6 ). Cooking may also significantly reduce the number of antioxidants in eggs ( 7 , 8 , 9 ). One study found that common cooking methods, including microwaving, boiling, and frying eggs, reduced the number of certain antioxidants by 6–18% ( 10 ). Overall, shorter cooking times (even at high temperatures) have been shown to retain more nutrients. Research has shown that when eggs are baked for 40 minutes, they may lose up to 61% of their vitamin D, compared to up to 18% when they’re fried or boiled for a shorter period of time ( 11 ). However, even though cooking eggs reduces these nutrients, eggs are still a very rich source of vitamins and antioxidants ( 5 ). SUMMARY Cooking eggs can reduce their vitamin and antioxidant content. However, they’re still very high in nutrients. High-heat cooking oxidizes the cholesterol in eggs Egg yolks are high in cholesterol. In fact, one large egg contains about 212 mg of cholesterol, which is 71% of the previously recommended intake of 300 mg per day (12). There’s now no recommended upper limit on daily cholesterol intake in the United States. However, when eggs are cooked at high temperatures, the cholesterol in them may become oxidized and produce compounds known as oxysterols ( 13 , 14 ). This is a concern for some people, as oxidized cholesterol and oxysterols in the blood have been linked to an increased risk of heart disease ( 15 , 16 ). Foods containing oxidized cholesterol and oxysterols are thought to contribute to the blood levels of these compounds ( 17 ). The main dietary sources of oxidized cholesterol may be commercially fried foods, such as fried chicken, fish, and french fries ( 18 ). It’s also worth noting that cholesterol that’s oxidized in the body is thought to be more harmful than the oxidized cholesterol that you eat ( 15 ). Most importantly, studies haven’t shown a link between eating eggs and an increased risk of heart disease in healthy people ( 19 , 20 , 21 , 22 , 23 , 24 ). SUMMARY High-heat cooking can oxidize the cholesterol in eggs. However, eating eggs hasn’t been linked with an increased risk of heart disease in healthy people.
