CR is anything but easy, it's considered one of the most challenging diets there is. That being said, there are varying levels of intensity amongst CR practitioners. Eating 90-95% of ad libitum (As much as you want) isn't that challenging. I'm down to 64% ad libitum, and it's pretty tough. I know people who do less than 60%, they look anorexic.
