>Is there actually any agreement among scientists that there is a causal relationship between fast food consumption and obesity? Yes and no...part of the problem, much like cigarettes there are many industry paid physicians and scientists happy to create confusion and dispel truth. And just like the cigarette industry who took their carcinogenic products to countries with less regulation, fast food and sugar industries are doing the same. First fast food is high calorie and low in nutrients. Its also high in carbs which tends to trigger insulin production, insulin enlarges cell size in the body including fat cells priming a body for obesity (just add excess calories here). Additionally, fast food is notoriously inflammatory (sugar, grain fed meat, gluten, additives, saturated fat, BPA type toxins, preservatives, fried, etc...) and inflammation is linked to obesity, of course coming full circle you will find scientists paid by the sugar/fast food industries happy to claim its the other way around and that obesity is linked to metabolic inflammation. I will highlight the comment below regarding the teacher on the McD's diet for 6 months who lost ~60lbs is the type of misinformation the food industry thrives off. Just to highlight, the individual lost 56lbs but was still classified as obese, the individual limited himself to 2,000 calories per day (which can easily be exceeded in a single meal) and the individual walked 45 minuted everyday, but there is no information pre-McD diet.
