Ketogenic Diet

ketogenic-dietA ketogenic diet is a diet high in fat and protein, and virtually no carbohydrate. This will force the body into a state of ketosis whereby ketones are used as a fuel source – rather than glucose.

Ketogenic diets have been used to treat epilepsy and for weight loss.

Many body builders also use a ketogenic diet during their ‘cutting’ phase (attempting to burn as much fat as possible while retaining muscle mass). Ketogenic diets have gained some popularity due to the extensive media coverage of low/no carb diets such as Atkins.

Is a Ketogenic Diet Healthy?

A ketogenic diet is suitable for some people – but most definitely not all. Depriving the body of carbohydrates can place significant strain on the body – particularly liver and kidney function.

Many people will feel considerably fatigued during the first few weeks of ketosis – the body is trying to adapt to using ketones as a fuel source. Ketones are a byproduct of fat metabolism (fat burning).

There are many opposite schools of thought regarding the safety of a ketogenic diet – however the fact that many epilepsy sufferers have successfully been using ketosis for years – certainly gives the diet some credence.

However, it must be done carefully. Many who start the diet stop it within a few days due to the fatigue and difficulty encountered.

  • Ketosis Guidelines

    In order for ketosis to begin dieters must strictly follow these guidelines:

    1. Eat no more than 60 grams of carbs per day or 5% total calories.
    2. 70% of your calories should be from fat.
    3. 25% should be from protein.

    If too much protein is consumed your body will convert it to glucose rather than converting fat to ketones.

    1. Kevin Short

      I started on a ketogenic diet on May 11, 2010 at 245 pounds; I am 6 feet 2 inches tall, and 52 years old. I have lost over 35 pounds so far, and a recent blood test showed all my numbers right in the good zone. There was one low number: sodium. I guess I should use more salt! I do take some of the best-rated vitamins, to make sure my vitamin K (and others) are good. I find it very easy to maintain. Two weeks into the diet I was having craving for sweets — but I turned my food over to the care of God, and immediately all cravings stopped. It works!

    2. Shay

      I started a 600 calorie ketogenic diet under a medical doctor on June 10th. I have a ton of vitamins/supplements that I have to take, along with a b-12 mixture (with some other things) that I take every 4 days and an appetite suppressant (1/2 a table twice a day..morning and very early afternoon).

      I have a ton of energy and up until now (the 3rd day), the diet has been easy. I don’t get hungry and I have a bunch of energy!

      I am a diabetic and just wondering how long it takes to see results. I know that it has only been 2 days, but it does not appear that any weight has been loss on my end.

      And, the only other liquids that I have been drinking beyond the shakes I was given is water. I’m drinking about 130 oz a day.

    3. Holly

      I have been on a ketogenic diet for the past 6 weeks and have noticed weight loss within the first week. My body has slimmed down significantly and left me with ungodly stretch marks. I recommend doing lots of light exercise at first and increase it gradually. I’ve noticed my acid reflux has almost disappeared and I’m no longer constipated. I would recommend this diet to everyone; however, it is definitely for those with discipline.

    9. Mary

      I do a ketogenic diet, and it has been very beneficial. i have very regular BMs without the aid of scratchy fiber. No cholesterol problems. I absorb nutrients much easier than before. If you stick with it, it will stick with you. I highly recommend it.

    10. Sandee

      I have been on Dr. Dillard’s diet for 10 days now and have lost 6 lbs. at least.. I don’t feel hungry and am not feeling bad at all. My fourth day was the hardest but on the diet you are advised to eat an apple if not feeling well and that should fix it, and it did. I am a diabetic and have had to lower my daily requirements for insulin and am seeing great bllod sugar results.

    11. Mark

      I used this diet before going on a more moderate diet, and was advised to work out really hard during it – the theory being that if you don’t, the cholesterol and fat’s gonna get me into trouble! The diet definitely worked – my workouts got really aggressive too, and I felt no ill effects after three days. I will recommend this though……if you don’t taker a fiber supplement twice a day with this diet, you are asking for BIG trouble in the bathroom!

      Dr. Floyd Dillard of Dillard Diet Designs uses this process very effectively for his patients. The process involves an initial 5-Day period where you eat only protein and drink lots of water, along with his custom vitamin supplements, B-12 shots and a controlled appetite suppresant. After those first few days, you add simple carbs such as fruit and veggies along with your protein. Sugar is not allowed nor are certain fruits due to their high fat and sugar content. Patients see Dr. Dillard once a week and he carefully monitors their health and progress. His success rate is very high. His program is genius and if you stick to it, he will help you get to the size you want and become healthy. If interested, you can find him at
