Study Spotlight: Long-Term Effects of Ketogenic Diet in Obese Patients

By: Joel Luedke

This week we are doing a mini feature on the ketogenic diet.  We feel like it is well deserved as the research coming out around the diet is showing some very beneficial results for many different applications.  There has been good evidence showing maintained and improved performance in endurance with keto-adapated individuals and there is also the potential to have good results in individuals that are focusing on strength and power.    One of the most exciting areas of research surrounding ketogenic diets is the application to helping with cancer treatment (see our podcast of the week for more information on that).  The potential of the diet helping improve outcomes in cancer prognosis and in the treatment of it with chemotherapy is astounding.

In this Study Spotlight we are looking at how well the diet works for sustained weightless.  Check out what the researchers found out below.

What They Did:
Researchers took 83 obese patients (BMI >35 and high glucose and cholesterol levels) and put them on a ketogenic diet for 24 weeks.  The diet consisted of 30g of CHO, 1g/kg body weight or protein, 20% saturated fat, 80% polyand mono unsaturated fat.  They measured several markers included but not limited to cholesterol, a lipid panel and fasting glucose pre- and post-diet.  Parameters were adjusted   after 8, 16 and 24weeks of intervention.

What They Found: 
All markers that were measured before the start of the intervention were measured again after the 24 weeks of the ketogenic diet.  There were significant drops in the levels of body mass and therefore the BMI.  There was also decreases in cholesterol, glucose and the 'bad' fats while there was an increase in the number of 'good' fats.  Also there were no negative side effects on the participants in the study.

What It All Means: 
The bottom line with the results of this study is that it works and in the process didn't cause any harm.  Now, that begs the questions does this work just the same as any other diet and it is a fair questions.  Odds are most 'diets' can work but often come with major caloric restrictions and often they are hard to follow.  The great thing about the ketogenic diet is you're eating high amount of fat which will give you a feeling of being full and feeling satisfied.  Yep, that's right you're eating fat to get thin (great new book out by Mark Hyman on that HERE).  Also with the higher amounts of protein you will also feel full and can still enjoy your steak and chicken throughout the diet in good sized quantities.  

If you're looking for a change up where you're requirement to count your calories as close and the restrictions are minimal in terms of amount of food consumed this is something yo may want to check out.  Please send us an email at if you have any questions.
