I'd argue that the common perception of sensible eating is wrong ie. whole grains, low fat etc.
Whether or not it's wrong (I don't particularly agree with the low fat craze, but that's fading out of the definition of 'sensible' eating), your first post was talking about calorie counting vs. 'maintaining sensible dietary choices'. If you really meant vs paleo, than you probably should have said so. When you asked the question, I was envisioning a more Mediterranean diet or some rules on sensible eating, like eat lots of plants, less processed foods etc.
I also don't know why refusing to eat lentils or steel cut oats or quinoa or even dairy is 'sensible'. Especially given the number of studies that say good things about eating all of the above.
Note - my info on the paleo diet and what's allowed and what isn't comes from
And perhaps restriction is a good thing?
Perhaps certainly leaves a lot of wiggle room - but to reiterate Spinner's question... why is
that much restriction better than a middle ground. Where you don't eat the 'see food' diet, but you're not going full paleo. What's wrong with a Mediterranean diet? What's wrong with the Okinawan diet replete with rice and sweet potato?
And why would I need more restriction on my food choices if my current one keeps me happy and healthy?
Don't get me wrong, if someone finds paleo easier than whatever I'm doing - more power to them! But people are so varied in so many ways, I don't know how you could say that all people would be better off with one plan or another. Generally they're better off with the plan that works best for them, whatever that happens to be.
Personally I haven't seen anything in paleo that offers enough advantages to try it. I've already been down a slightly less restrictive path before and that was hard enough. Cut out beans and sweet potato and canola and quinoa and omg cheese and yogurt and milk... I'd have to be dealing with severe allergies to make the stress worth it to me. (I've also done a 6 week anti-allergen diet. No dairy, no wheat, no sugar, no 'fake' sugars, mostly no preservatives beyond calcium citrate and similar... It was super duper hard)
