“However, saturated fat has long been lauded as a heart-harming macronutrient; the American Heart Association recommends no more than 13 grams of saturated fat per day. In fact, Nieca Goldberg, M.D., medical director of the Joan H. Tisch Center For Women’s Health at NYU Langone Medical Center, said saturated fats can increase bad cholesterol.” -Christina Stiehl, PopSugar reporter17
For the ketogenic eating plan, participants were instructed to reduce non-fiber-containing carbohydrates to between 20 and 50 grams a day, with no calorie restriction. The group following the plate method were told to eat their meals on a nine-inch plate, filling half of it with non-starchy vegetables (eg, greens, peppers, broccoli, carrots), ¼ of the plate with whole grains (eg, brown rice, sweet potatoes, whole wheat bread) and adding lean protein (eg, skinless chicken, turkey, fish, and seafood) to the last quarter of the plate.1
Advocates for the diet recommend that it be seriously considered after two medications have failed, as the chance of other drugs succeeding is only 10%. The diet can be considered earlier for some epilepsy and genetic syndromes where it has shown particular usefulness. These include Dravet syndrome, infantile spasms, myoclonic-astatic epilepsy and tuberous sclerosis complex.
Finally, people eat about nine servings of fruits and vegetables a day on a Mediterranean diet. (1) Produce packs an array of disease-fighting antioxidants, and people who fill their diet with these foods have lower risk of disease. Yet as the National Institutes of Health points out, it’s not known if it’s the antioxidants or other compounds (or general healthy eating patterns) that are responsible for these advantages. (5)
Many dieters shy away from nuts because of their high calorie and fat count. But studies show that eating a handful several times a week can prevent heart disease and ultimately help you shed pounds since they fill you up and stop you from snacking on other things. Almonds, in particular, contain lots of monounsaturated fats and fiber. (Healthy swap: Replace peanut butter with almond butter.)
What the expert says: ‘There is a large amount of evidence to suggest that following the MD reduces your risk of cardiovascular disease,’ says registered Dietitian and British Dietetic Association spokesperson Kirsty Barrett. ‘Significantly, a meta-analysis of randomised-control trials in 2011 found that the MD was effective for weight loss, though results were better when the diet was combined with energy restriction and physical activity. It has also been found to reduce LDL (bad cholesterol) more than low fat and low carb diets.’
Changing your body’s primary energy source from carbohydrates to fat causes an increase in ketones in the blood. This “dietary ketosis” is different from ketoacidosis, which is an extremely dangerous condition. When you have too many ketones, you may be at risk for developing diabetic ketoacidosis (DKA). DKA is most prevalent in type 1 diabetes when blood glucose is too high and can arise from a lack of insulin. Although rare, DKA is a possibility in type 2 diabetes if ketones are too high. Being ill while on a low-carb diet may also increase your risk for DKA.

6. Longer life. A recent meta-analysis in the British Medical Journal found the diet significantly improved health and led to a 9 percent reduction in death from heart disease, cancer, Parkinson's, and Alzheimer's. Other studies have found that the diet's healthy fats may lessen the inflammation and pain of rheumatoid arthritis and cut the risk of getting amyotrophic lateral sclerosis (Lou Gehrig's disease) by 60 percent.
While the American Diabetes Association notes that many individuals with the disease or its precursor, prediabetes, employ carb counting to control their blood sugar on a regular basis, others have turned to ultra-low-carb diets as a way to manage their symptoms. These diets are highly restrictive and often limit followers to consuming no more than 20 grams (g) of carbs per day, usually with no added sugar, and, depending on the diet, increased protein and fat. Experts say they rarely have patients who ask about following a ketogenic diet or a modified paleo diet long term, but they can be useful for short-term weight loss if done properly.
There are three instances where there’s research to back up a ketogenic diet, including to help control type 2 diabetes, as part of epilepsy treatment, or for weight loss, says Mattinson. “In terms of diabetes, there is some promising research showing that the ketogenic diet may improve glycemic control. It may cause a reduction in A1C — a key test for diabetes that measures a person’s average blood sugar control over two to three months — something that may help you reduce medication use,” she says.
