I like it, but should I avoid it?
The first few ingredients of Kellogs corn flakes are: MILLED CORN, SUGAR, MALT FLAVORING, HIGH FRUCTOSE CORN SYRUP. It contains 24g of carbohydrate per serving and no fat.
If you believe that people gain weight because of sugar and other refined carbohydrates, the 24 grams of carbs in this cereal should worry you, but the milk shouldn't.
If you believe people gain weight because of fat intake, the 0 grams of fat in the cereal looks perfect, and the milk should be skim.
I happen to believe that refined carbohydrates are the problem, as described in the published research on this page: http://www.dietdoctor.com/weight-loss-time-to-stop-denying-the-science
But, the jury is still out.
Carbs are carbs, whether they be cornflakes or soda or popcorn or chocolate. Reduce them if you want to lose fat. Lift some weights. Keep overall calories under control (not too low).
For corn flakes, you can use the "double" toned milk. After getting the "double" toned milk, boil it fully, then let it cool down "completely". On the cooled milk, you'll see a layer of cream. Take that cream out with a spoon or a tea filter, before you put it in the corn flakes.
This way you'll consume a lesser amount of fat than with the usual milk.
Moreover if you are bent on having the cornflakes, then Kellogg;s have a new variety named "Kellogg's Special K". They claim it to be 98% fat free.
