Meh; there are so many pathways to the creation of fat cells, or their precursors, (and this really explodes if you start considering some things to 'inevitably' lead to fat production based on lifestyle) from different food molecules. Realistically, everyone who is overweight just needs to stop eating so much, and change what it is they eat. Without anything else like manifest diabetes or heart disease or whatever, anyone who is packing too much weight can just limit their portions, reduce sugar intake, drink more water, and get 30 minutes of activity a day. The greater your portion (calorie) limitation, sugar reduction, water intake, and activity, the more weight you will lose/faster you'll lose it. Stuff like eating more veggies and fruit, and learning to cook and not eat processed bullshit is just icing on the cake.
