Additionally, it has been used to treat epilepsy since the 1920s (2).
Here are 10 graphs that show the many powerful benefits of a ketogenic diet.
The ketogenic group was also less hungry and found it easier to stick to the diet.
Bottom Line: The ketogenic diet is effective for weight loss. It is superior to a high-carb diet, and may even provide a metabolic advantage.
This kind of stored fat can increase the risk of heart disease, type 2 diabetes and premature death (12).
Interestingly, a ketogenic diet is a very effective way to lose belly fat.
These findings were more apparent in men than women, probably because men tend to store more fat in this area.
Bottom Line: A ketogenic diet can help you lose belly fat, which is closely linked to heart disease, type 2 diabetes and reduced life expectancy.
The graph shows that runners who are adapted to a ketogenic diet can burn 2.3 times more fat per minute during a workout, compared to runners on a low-fat diet.
Over the long-term, an increased ability to burn fat can provide various health benefits and protect against obesity (15).
Bottom Line: A ketogenic diet can drastically boost your ability to burn fat during exercise.
Over the years, high-carb diets and poor insulin function can lead to high blood sugar levels (16).
Interestingly, a ketogenic diet can be highly beneficial for people with diabetes and high blood sugar levels.
Bottom Line: The ketogenic diet is extremely effective at lowering blood sugar levels, a key marker of long-term health.
This study found that a ketogenic diet significantly lowered insulin levels in diabetics, which indicates reduced insulin resistance (21).
The ketogenic group also lost 12.8 lbs (5.8 kg), while the high-carb group lost only 4.2 lbs (1.9 kg). Triglyceride levels decreased by 20% in the ketogenic group, versus only 4% in the high-carb group.
Bottom Line: A ketogenic diet will drastically reduce insulin resistance, one of the most important markers of metabolic health.
The increased risk can be as high as 30% in men, and 75% in women (26).
This study found that a ketogenic diet lowered fasting triglyceride levels by 44%, while no change was found with the low-fat, high-carb diet (24).
Additionally, the amount of fat in the blood after meals was significantly reduced, as shown in the graph above.
The ketogenic diet also improved other markers of metabolic syndrome. For example, it caused more weight loss, decreased the triglyceride:HDL ratio and reduced blood sugar levels (24).
Bottom Line: Despite a very high fat content, the ketogenic diet can cause massive reductions in blood triglyceride levels.
One of the best ways to raise HDL is to increase dietary fat intake on a low-carb or ketogenic diet (16).
As you can see in the graph above, a ketogenic diet can cause a major increase in HDL levels (16).
Bottom Line: HDL (the "good") cholesterol plays a key role in cholesterol metabolism, and is linked to a reduced risk of heart disease. A ketogenic diet can cause a big increase in HDL levels.
When dieting, constant hunger often leads to binge eating or quitting the diet completely.
One of the main reasons low-carb and ketogenic diets are so beneficial for weight loss, is the fact that they reduce hunger.
The study above compared a ketogenic diet to a low-fat diet. The ketogenic diet group reported much less hunger, despite the fact that they lost 46% more weight (6).
Bottom Line: Hunger levels play a key role in dieting success. A ketogenic diet has been shown to reduce hunger compared to a low-fat diet.
Since the 1920s, researchers and physicians have tested and used the ketogenic diet for the treatment of epilepsy (2).
As shown in this graph above, one study found that 75.8% of epileptic children on a ketogenic diet had fewer seizures after only one month of treatment (32).
Moreover, after 6 months, half of the patients had at least a 90% decrease in seizure frequency, while 50% of these patients reported a complete remission.
At the start of the study, a large majority of subjects were malnourished and below a healthy weight. By the end of the study, all subjects had reached a healthy weight and improved their nutritional status (32).
One year after the diet, 5 of the 29 participants remained seizure-free, and several of the participants reduced or completely stopped their anti-seizure medication.
Bottom Line: A ketogenic diet can help reduce the frequency of seizures in epileptic children. In some cases, the diet can eliminate seizures altogether.
Medical interventions for brain cancer can fail to target tumor cell growth and often negatively affect the health and vitality of normal brain cells (33).
This study compared a normal diet (shown as SD-UR) to a higher-calorie (KD-UR) and calorie-restricted ketogenic meal plan (KD-R) in mice with brain cancer.
The bars in the graph represent tumor size. As you can see, the two tumors were reduced by 65% and 35% in the calorie-restricted ketogenic group (KD-R) (33).
Interestingly, no change occurred in the higher-calorie ketogenic group.
Although research is still in its early stages, it is likely that a ketogenic diet will eventually be used alongside more conventional cancer treatments.
