My experience with diets like vegetarian, vegan, low-carb, paleo, fasting and SAD, is that paleo with some kind of carbohydrate timing is a good point of departure. I would recommend cyclic ketogenic paleo for overweight people as well as for those with low levels of and/or low intensity activities.

I have to respectfully disagree, niner. You can not be vegetarian and paleo at the same time. I suppose the definition of the "paleo diet" has become increasingly diluted with its popularity, but as far as I know none of the authorities on the subject agrees that vegetarians can be paleo and most of them have explicitly stated this. You need not go further than the first popular book on the subject, The Paleo Diet, to find an explanation.
Is that because dairy isn't defined as paleo? There are a lot of people who are well adapted to dairy, so although it's technically "cheating", I think you could slip it in and still call your diet "paleo", providing you were adapted to it, i.e. not lactose intolerant or having allergies to it. A lot of people think that paleo means hyperlipid, but that is not Loren Cordain's view, nor mine. If one chooses to be vegetarian or vegan, it will be harder to construct a healthy diet, but not impossible.

Nevertheless, in my opinion, the healthiest diet is pescetarianism.

What about contamination of seafood with mercury, lead, and other heavy metals in addition to PCB's, DDT, and other pesticides and industrial chemicals and not to mention radiation contamination. And then we have bacteria and biotoxin contamination of shellfish. Virtually all pollution and environmental contaminants drain into waterways and downstream into the seas and oceans where they continue to accumulate in ever greater concentrations. Chemicals, heavy metals, radiation, and sewage. Virtually everything eventually ends up in the seas and oceans.
As healthy as seafood
Unfortunately, in today's world, (exclusively) eating large amounts of seafood may not be in our best interest for health. As you have no way of knowing the level of health jeopardizing heavy metal, industrial chemical, or radioactive contamination you may be ingesting with each seafood dinner. And the consumption of each portion of contaminated seafood on a regular (daily) basis will allow ever higher levels of contaminates to accumulate and build in our tissues until our health has been adversely and irreparably harmed as well.
The safest bet, as with everything, is the time tested rule "all things in moderation". Or in other words, it is probably healthier (or at least "more" safe) to cut back on the surf by adding in some turf (the best of both worlds).

a diet excluding known allergens like gliadin, lactose etc
I don't know about you but I surely don't have any allergies to either gluten or lactose. But that doesn't mean it would be healthy to eat white bread by the loaf or pasta by the bowl or chug milk by the gallon. Like I said, it is much safer to consume in moderation and not to over indulge in any particular food group. Your mother should of taught you to eat in moderation and not to over indulge.
People with food allergies are in the minority but like any other health condition, if it doesn't agree with you, then simply avoid the offending staples. This isn't rocket science here.

Traditional Okinawans have the best claim as the longest lived community, and their diet incorporates a 10% calorie restriction compared to other Japanese, and is 85% carbohydrate, 9% protein, and 6% fat. 4% of their calories come from animal products, primarily fish, and only 2% is saturated fat. As far as I'm concerned, that suggests the starting point for any longevity diet should be a mildly calorie-restricted, and profoundly protein, fat and sugar restricted, near-vegan diet. This makes eminent sense with what we now know of nutrient signalling by insulin, IGF-1 and amino acids, as well as inflammatory signalling by fats.
We can do better than traditional Okinawans, but I doubt there's much to be gained in tweaking their macronutrient intake. The advances we make over this culture will come through hacking biological aging pathways (AMPK, Sirt1, autophagy, telomerase, xenobiotic response, inflammation, superoxide production, epigenetics) in ways that weren't forseen just a few years ago.
Paleo diets are undoubtedly superior to mainstream Western diets in their low glycemic indices and embrace of whole-plant foods, but they're more suited to bodybuilders who want elevated growth signalling, than to those of us who are trying to square our mortality curve as much as possible. As Gems and Partridge ably summarise, growth causes aging.

I didn't know that eating animal proteins would have the same effect on insulin as sugar!
Claims Dr. Greger, the vegan ideologue who usually distorts the science to make his preselected point. We'd have to start by noting his definition of "paleo", which is likely to be hyper-meat. A paleo diet doesn't need a lot of meat, or any, for that matter.

If we take paleo to simply mean minimally processed foods, then just about anything from the produce section of the grocery can qualify. If calorie and methionine restricted, then its also likely consistent with longevity practice.
