I never claimed that you did change your exercise routine but that has nothing to do with anything that I said. Again, most people don't have 1500 calories that they can cut from their diet. If they did cut that much, it is more likely to put their body in starvation mode, which is bad. For people that are overweight, what we want is the body to be in ketogenesis, that is, breaking down fat in order to provide calories.

Also insulin resistance is the precursor to diabetes, considering that America is currently suffering from rising levels of diabetes, I am comfortable saying that insulin resistance is fairly common (as in, you know someone that is insulin resistant).

“most people don't have the time to go throw 45's around a gym for an hour a few times a week”

“For people that are overweight, what we want “

“cutting out the extra calories won't help once insulin resistance happens.”

It sounds like you are overweight, sedentary, and insulin-resistant.

I mean this in all sincerity and without any mean spirit:

Please find a way to get healthy. If what you are doing is working, great. If not, reconsider your approach. Please do not give nutrition advice to others until you are actually healthy.

How many extra calories does ketosis burn? I've read that it's only about 300 per day.

Again - I suspect that most low carb diets work because you're eating less calories. Mainly because people don't realise how many calories there are in carbohydrates.
