Quick read here http://annals.org/article.aspx?articleid=1900694. Basically high crabs are bad for weight loss and heart disease. I think there have been a number of recent studies that say the same thing. And long read here http://www.theguardian.com/society/2016/apr/07/the-sugar-conspiracy-robert-lustig-john-yudkin basically saying that fat is not as bad as we thing sugar is a problem though.

How does this all come back to our meat discussion? Well what is high in fat low in sugar and is a large portion of a meal. If you eliminate it you need to replace it with something else. For most people that something else would be a carb and carbs are high in starches that quickly break down into sugars.

Now you say just dont eat the carb vegetables eat more beans and Legumes but its not very easy to pull off. For one you have to spend more time cooking and 2 you have to learn new recipes and change your taste pallet.

Right now I cook by walking the outside of the grocery store, buying meat and raw ingredients and then cooking a meat and a vegetable for most meals. I might supplement with occasional starches like bread but I do my best to avoid them. All the bones an extra bits that are getting old get turned into stock and reincorporated into next weeks meal. When I try to change that to go all veterinarian I really struggle. I either need to use some sort of weird processed shit like tofurky, or I need to crate a rather complex stew like meals. I cant just cook a Chunk of meat and steam some broccoli and be done in about 15min.
