Benefits are proportional. Over the longer term, the simplest way to judge calorie intake is weight. Most nutrients should come from foods, not supplements. CRON, ideally, is about minimizing calories and harmful substances, while maximizing nutrients. Then, small amounts of fish, lean meat, or other protein.
Beans are good.
For those well into a CRON program this is not usually a problem. Ideally you want a comprehensive baseline test of biomarkers before you start. Positive experience, not what 'I shouldn't do'. Pre plan day with some great meals. Crowd out bad foods with good foods.
