Willet on Trans Fats, Carbs and Protein


"Q:Will eating a calorie of fat make you fatter than eating a calorie of carbohydrate?
A: From many kinds of studies conducted over years, we are quite confident now that a calorie from fat will cause a similar amount of weight gain as a calorie from carbohydrate. There are some interesting questions about whether eating carbohydrate calories versus fat calories will make you eat more calories, but based on what you put into your mouth, it's pretty clear that the source of the calories is really not important."

"We've now looked at over 250,000 men and women for up to 30 years, and we [also] haven't seen that the percentage of calories from fat or from carbohydrates in your diet makes any difference in relation to heart attacks, various cancers or stroke. Having said that, the type of fat is very important, and so is the type of carbohydrate. So we find that trans fats, again, are particularly harmful with regard to type 2 diabetes and heart disease. On the other hand, unsaturated fats are actually beneficial in terms of reducing the risk of heart disease and type 2 diabetes. It's the same with carbohydrates. The total amount is not important. But high intake of refined starch and sugar is related to a higher risk of heart disease and diabetes, whereas high-fiber whole-grain carbohydrates are related to a lower risk. That's not too surprising, as we know that high intakes of sugar and refined starch have an adverse effect on blood glucose levels."


It would be unusual to see one so close to the conventional wisdom say anything more than the above - but essentially everyone agrees on the negative aspects of transfats.  Sadly, it was phobia of saturated fats - proven more and more unfounded by the day - that made the transfats a common part of diets.


If you can eat those whole grains and control your hunger and blood sugars - more power to you.
