Want to Lose Fat – Restrict Your Carbohydrates
In 1956 Prof. Alan Kekwick and Gaston Pawan, MD, at Middlesex Hospital, London, England, conducted tests of 4 varieties of 1,000 kcal/day diets: 90% fat (by fuel values), 90% protein, 90% carbohydrate, and a normal mixed diet.
Subjects on the high-fat diet lost much more weight than any of the others. Several subjects on the high-carb diet actually gained weight, even at only 1000 kcal/day!
Even at 2,600 kcal/day of very low-carb diet, subjects lost weight. Thus the dogma that a “balanced” diet is best for almost everyone had been falsified a half century ago.
Examination of at least two dozen recent controlled diet trials by an equal number of authors in several countries led to these conclusions:
1. Carb restriction improved control of serum glucose, the primary target of nutritional therapy, and reduced insulin fluctuations.
2. Carb-restricted diets are at least as effective for weight loss as low-fat diets.
3. Substitution of fat for carb is generally beneficial for markers of and for the actual incidence of cardiovascular disease. [This means that a diet of 25% carb, 25% protein and 50% fat will be optimum for many folks. Some have followed such diets for over 50 years.]
4. Carb restriction has benefits even in the absence of weight loss.
