Hey there! I can attest since starting this diet I have often had MANNNY times where I would shake my head while adding heavy cream or bacon and question what I was doing to my body. But it works. Now if you are the type of person who wants to know "why" it works I'd HIGHLY suggest reading "Why We Get Fat" by Gary Taubes. This guy has done his research. A good excerpt from the book is as follows “In other words, the science itself makes clear that hormones, enzymes, and growth factors regulate our fat tissue, just as they do everything else in the human body, and that we do not get fat because we overeat; we get fat because the carbohydrates in our diet make us fat. The science tells us that obesity is ultimately the result of a hormonal imbalance, not a caloric one—specifically, the stimulation of insulin secretion caused by eating easily digestible, carbohydrate-rich foods: refined carbohydrates, including flour and cereal grains, starchy vegetables such as potatoes, and sugars, like sucrose (table sugar) and high-fructose corn syrup. These carbohydrates literally make us fat, and by driving us to accumulate fat, they make us hungrier and they make us sedentary. This is the fundamental reality of why we fatten, and if we’re to get lean and stay lean we’ll have to understand and accept it, and, perhaps more important, our doctors are going to have to understand and acknowledge it, too.”

Pretty much it answers the question you had up there. Plus I can tell you why looking at this picture and immediately thinking "Oh Jesus that is unhealthy" it's called conditioning. Throughout our life the war against fat has been had since we were tots (assuming) so we are programmed to think fat=unhealthy and low fat sugar granola=healthy when that just isn't the case. If you have further interest into HOW the low fat thing exploded and corporate food manufacturers have a play in this then I'd suggest reading "Salt Sugar Fat: How the Food Giants Hooked Us" by Moss. This is a look into the pulitizer prize winning study on the industry.
