Low fat diets cause an average weight loss of 5.5 pounds according to a recent review by Arnie Astrup of sixteen low-fat studies. Weight loss of 0.8 lbs for every one percent reduction in fat
The average weight loss was 0.8 pounds for every one percent reduction in fat as a percent of total calories (for example, reducing fat intake from 37 percent of calories to 36 percent.)
10% reduction in fat should cause weight loss of 9.7 lbs
Therefore a 10 percent reduction in fat intake, for example, from 40 percent to 30 percent of calories, the predicted weight loss would be 9.7 pounds according to Astrup.
Conclusion: No increase in heart attack risk
Astrup also notes that decreasing fat intake and increasing complex carbohydrate intake does not increase the risk of a heart attack, and in fact, have been shown to reduce the risk of death in high risk patients.
“Low fat diets with a high content of complex carbohydrates and protein do not produce any adverse effect on cardiovascular risk factors when weight loss is allowed to occur, and they have been shown to decrease mortality among high risk subjects,” Astrup concludes.
