First, foods from plants contain less total and saturated fat, resulting in reduced caloric intake, weight loss, and improved A1C levels. Second, independent of weight loss, a low-fat, plant-based diet improves insulin sensitivity, presumably by reducing intramyocellular lipid accumulation. As insulin sensitivity improves, carbohydrate tolerance increases. Third, participants in the diabetes studies by Barnard et al.
Overhang: That portion of the roof structure that extends beyond the exterior walls of a building. Penetrations: Vents, pipes, stacks, chimneys-anything that penetrates a roof deck. Pitch: The degree of roof incline expressed as the ratio of the rise, in feet, to the span, in feet.
Another approach might be to have a longer overhang at the gables than at the eaves. But again, I think that would look awkward. With the 36 overhang, I will use roof support brackets. I like the look of a generous overhang, and the support brackets. I don't think there are any hard and fast rules. The pitch, and overhang are a balancing act to get the most performance with the least cost.
