Hmm...must be something else in the environment then. I lost weight effortlessly while living in Europe but I always assumed that was due to being cut off from processed foods and food items with unnecessary additives. It's nearly impossible for me to maintain an equally healthy diet here in the US because it's simply too annoying and it's also much easier to give into the temptation to eat junk food. I'm too lazy for things like dried beans though, I always prefer canned (as long as I can get the ones that are just beans, water and salt).

Beans are literally dump some in water overnight and then cook the next day. It must be 5m of labor total.

I don't usually plan what I'm cooking that far in advance so it's not practical for me personally and there's really not much difference between dried beans and canned unless you're buying the ones with sugar or you have a medical reason to avoid sodium

Of course do what works best for you. I avoid cans because a family member used to work in a plant making cans. Industrial chemicals are involved.

And then there are the millions of cats with hyperthyroidism that has been connected to canned cat food.

And you think industrial chemicals aren't involved in producing the packaging dried beans come in?

As opposed to canned beans they aren't sitting in liquid interacting with their packaging. So you can wash the dried beans before you use them.

And I generally buy in bulk at the outdoor market so relatively few beans even come in contact with the packaging.
