How many diets have you tried? How many times have you failed? The term ‘fad diet’ is a gross understatement, all diets are fads. I cannot think of a single diet that has been around for years, can you? Most diets are difficult to follow – bland, costly, and inconvenient – subsequently, there is a high rate of non-compliance to the diet strategy. What if a diet asked you to eat a little healthier and take 1 day off per week? That doesn’t sound that hard does it?
The concept of Intermittent Fasting has been around for many years. In fact, our ancestors were forced to occasionally fast. Recently, I learned about intermittent fasting by John Berardi, Founder of Precision Nutrition System and leading nutritional scientist. I read his book and became hooked on the concept. In the simplest explanation, one day a week, you fast for an entire day (20-24 hours). For example, eat regular meals Tuesday through Sunday. On Sunday night eat dinner at your normal time (7 pm). Then don’t eat until Monday evening at dinner time. During the fasting period, drink water and take a multivitamin if you want to. When you resume eating, don’t run to a fast-food chain and order 3 double cheeseburgers, an extra large fry, and a milkshake. Just, resume normal, healthy eating.
“I’ll Starve to death”, is the immediate response. No, you won’t. Our ancestors went 2-3 days without eating, they survived. Second, you will quickly learn that you are less hungry at hour 20 than you were at hour 4. We have hormones in our body, which trigger the feeling of hunger, but once you get past the initial hunger phase, the hormone response is suppressed and hunger subsides.
A single day of fasting creates a negative energy balance (expending more calories than consuming) of 2000-3000 calories. Consider that one-pound of fat is equivalent to 3,500 calories, you can see how easy it is to reach the negative energy balance and weight loss. There are physiological benefits that go beyond negative energy balance and weight loss:
- Improved blood lipid profile (decreased LDL, increased HDL)
- Reduced blood pressure
- Reduction of inflammatory markers such as C-Reactive Protein
- Improved fat metabolism
- Increased insulin sensitivity (blood sugar control)
- Enhanced Autophagocytosis (cellular repair)
It should be noted, that the above is based on fasting for 18-24 hours. Fasting for longer periods or more frequently does not enhance or expedite these results. Improving health is never quick and easy. Exercise or diet alone will not create life lasting health improvements. The improvements noted above are a result of intermittent fasting, combined with overall healthier eating and regular exercise. Ultimate health and wellness come from a combination of diet and exercise.
Two months ago I started a paleolithic diet after doing my own independent research on diet and inflammation (I blogged about it). The data was so overwhelming I had to try it for 30 days. I loved it. Now I am combining a less strict version of Paleo with John Berardi’s intermittent fasting program. After 45 days, I lost 15 pounds and feel fantastic. Easiest diet I have tried.
