It has been estimated that 80% of excess calories Americans consume come from snacks. Americans do not need to be encouraged to eat between meals. It is already our downfall.
Johnson concluded that extra insulin produced in the normal mice by the high-fat diet caused their obesity, which strongly suggests that mice – and, by extension, humans – may make more insulin than they need.
Keep in mind that fat is not a normal part of the mouse diet, so it was only normal that healthy mice fed fat would become obese.
Fat is, however, a part of the human diet, one which our digestive system is able to use for energy as the lean mice did, at least provided there is not an excess of total calories.
If minimizing insulin production is potentially healthy for mice, and minimizing insulin production in humans has the potential for being healthier than maximizing insulin production, an obvious conclusion they tiptoed around would be that humans should eat a moderate or lower carbohydrate diet to minimize production of insulin. I guess that would have been too iconoclastic, or perhaps the research was funded by agribusiness, which makes their profit by processing a few pennies worth of wheat and selling it to consumers for big bucks.
One thing that the research did not support or even address was the idea that this will lead to a pill people can take to end obesity. The reporters probably felt the story would get more readers if they threw that in.
