The logic is that - weight-for-weight - fats are the most energy-dense member of the three [fat|carbohydrate|protein] food-groups.
So if you eat a given *weight* of food, the fat-richest option will contain the greatest number of calories - and any 'excess' calories [in whatever form they are ingested] will in turn be mutated by the Glycogen cycle and laid down in your body's fat-stores.
What do I know? well, my first job after graduating was programming an animal-feed mill to produce the contractually-specified protein/carbohydrate/fat component-ratios in pig-feed at the lowest-possible ingredient-cost. |d|i|g|i|t|a|l| PDP11/23 meets Animal Nutrition.
I mentioned this the other day. Advertisers like to sell 'low fat' or 'fat free' food because a lot of people are under the impression that it won't make them put on weight. If you eat an excess of anything, it can make you fat. Likewise, if you undereat even with fatty foods, it's likely that you won't end up getting fat. It's more convenient for people to think of metabolisms that way, because the truth isn't what they want to hear.
I only recently noticed how, if you look at the actual energy content of "low fat" food, it's surprisingly close to the full-fat stuff. I think I saw only about a 20% difference between half-fat and full-fat milk.
Of course fat gets first broken down into fatty acids in your digestive system. If your blood sugar levei is low, these are converted to glucose. If your blood sugar level is high, glucose will be converted back to fatty acids, and fatty acids back into triglycerids for storage ... body fat.
So, yeah, fat does not directly go into your fat cells, it runs through your metabolism like any other nutricient. But out of all nutricients, fat packs the most calories per weight unit ... so if you want to cut down on your calory intake, reducing the amount of fat is the easiest way.
This means generally reducing the fat content of your food is usually a good idea, as long as you replace it with something that has less calories :) And that's where a lot of misleading advertising happens. Of course, gummy bears have 0% fat. But that doesn't mean they're more healthy when they consist of 95% Sugar :)
