The weight loss mantra we’ve heard for years. Eat less then you burn and you’ll lose weight. Is it really that simple?
Dr. Michael Eades talks about two separate studies done in calorie resstriction that yield remarkably different results …
In the first experiment, performed by Dr. Ancel Keys, 36 young males were recruited to a 36-week study. They were fed plently of food – about 3200 calories a day – for the first 12 weeks of the study. After 12 weeks, food intake was cut to two meals a day. The diet was high in carbohydrate and low in fat. The average calorie count was during the 24 weeks of starvation was 1570 calories, with the macronutrient breakdown being roughly 25% protein, 17% fat, and 57% carbs.
So what happened to the subjects during the starvation portion of the study? They starved and obsessed about food constantly. One subject suffered such psychlogical turmoil that he chopped of several of his fingers. Not so pleasant.

In contrast to this study, we are pointed to another done by Dr. John Yudkin at the University of London in the 1960′s. Eleven subjects were recruited to go on a ‘low-carb’ type of diet plan for two weeks – consisting of milk, meat, eggs, grean leafy vegetables, etc. The amount of food they were allowed to eat was not restricted.
The subjects reported no feelings of hunger, in fact reported feelings of well – being, and without being restricted in any way, averaged 1560 calories, roughly 21% protein, 61% fat, and 17% carbs. Remarkably similar overall calorie intake to that of the Ancel Keys study, but clearly, far different results.
Although not conclusive, a direct comparison of these two studies does make a pretty compellingly case for the fact that a calorie is in fact not just a calorie – the type of food you eat makes a huge difference in how you feel during your weight loss efforts.
