low carb diet and sailing

[MarkCX]

There is also the suggestion that the position of our eyes and our selection of teeth made us more likely to have a had a significant proportion of meat in our diet in earlier times. More omnivores than carnivores, but certainly not herbivores. It was probably a case of eat whatever you can get, whenever you can. The problem now is that many of us can get whatever we want, whenever we want, rather than have an enforced reasonably balanced diet.

You are full of aggressive posturing. Got some raw nerves exposed?

I'm not promoting a paleo diet as a diet for the population, but I am saying that meat is extremely healthy contrary to the leftist political indoctrination coming from vegan zealots. Health trumps a concern for animals and it trumps a concern for the environment and I resent the preachy holier than thou attitude of vegetarians and vegans, who try to mess around with my health for political reasons.

I'm not spouting anything, unlike you and I've done my research. The evidence of early man being animal based principally is incontrovertible. Here is a paper on the subject (and there are many, many more like it). To quote from it:

...Neanderthals and early modern humans had similar dietary adaptations, obtaining most of their dietary protein from animals...

Out of Africa: Modern Human Origins Special Feature: Isotopic evidence for the diets of European Neanderthals and early modern humans..

Neither posturing nor aggressive, just find it odd that someone who is willing to slag off vegetables as the work of the devil and pinko feminist liberals, then falls for an even weirder diet fad. By slagging off at one group, you place yourself as promoting the alternative.

To quote from your link:
We report here on the direct isotopic evidence for Neanderthal and early modern human diets in Europe. Isotopic methods indicate the sources of dietary protein over many years of life, and show that Neanderthals had a similar diet through time (≈120,000 to ≈37,000 cal BP) and in different regions of Europe. The isotopic evidence indicates that in all cases Neanderthals were top-level carnivores and obtained all, or most, of their dietary protein from large herbivores. In contrast, early modern humans (≈40,000 to ≈27,000 cal BP) exhibited a wider range of isotopic values, and a number of individuals had evidence for the consumption of aquatic (marine and freshwater) resources. This pattern includes Oase 1, the oldest directly dated modern human in Europe (≈40,000 cal BP) with the highest nitrogen isotope value of all of the humans studied, likely because of freshwater fish consumption. As Oase 1 was close in time to the last Neanderthals, these data may indicate a significant dietary shift associated with the changing population dynamics of modern human emergence in Europe.

For an alternative view [from the hard left, radical feminist vegan army that is Scientific American}, try this:

Human Ancestors Were Nearly All Vegetarians

But if you want to base your diet on that of a species that died out 40,000 years ago, knock yourself out.

For heaven's sake you love to twist words. I didn't slag off vegetables, I actually said I eat a lot.

You are misinterpreting the article I linked to previously Your highlighted quote actually supports the dominant carnivore proposition. It is simply saying the type of animal protein changed to include more fish and less high level predators when compared to Neanderthals.

Your article says if you look at our early ancestors they were apes and apes have a mainly vegetarian diet, so our early ancestors were vegetarians. Sure, that's true, but if you looked even further back we were all plankton. It's a silly conclusion. We evolved into a different animal. Homo Sapien and Neanderthals as my article shows were carnivores principally in so far as that is how we got most of our protein.

As we evolved into carnivores, we evolved and adapted our biology to eating animals and it is therefore likely to be a healthy food for us.

My point was that even a couple of days of no dietary discipline on the boat makes it really hard to build good eating habits in the rest of your life

That whizzed passed me at the speed of light. If an individual cannot take a break from the usual eating habits for a few days/weeks/months then step ashore and return to "normal" then nobody can help them.

I wonder how the amazing people who do things like the Vendée Globe cope? All that dehydrated food cooked on a jet-burner and no fresh fruit and veg for months.

Indeed you are right a huge part of the UK population is almost beyond help with their obesity. Wander round any city center and ask yourself how many of the huge people you see struggling to get around actually want to be that size? Almost none & many are sad & desperate that it is so hard to shift the weight, a crash diet gets it off for a while, but relax for a moment and it comes racing back, humans developed an amazing capacity to store calories when famine loomed.

As a society we understand addiction in the form of Heroin, tobacco, alcohol and we know the difficult path needed to get off the cycle, we know that even one relapse sets the journey back considerably. But we have yet to accept that refined white sugar, corn syrup and omega 6 oils are in such concentrated forms & overdose quantities that they set up an addiction that is as hard as the accepted drugs to get free of. And worse, they are everywhere, sometimes difficult to isolate, disguised by the food industry & beneficial in small quantities and have no impact on a lucky few who were born with the right genes.

So yes Sandy, for many (but not all) middle aged sailors struggling with their weight, good eating habits at home that get abandoned when on the boat have a tremendous impact, not because of the calories delivered, but because they set back the deep establishment of healthy eating habits. You wouldn’t tolerate a reforming heroin addict or smoker to relapse ‘only when on the boat’ so why allow it with food.

Many readers of this will shout that food cannot be equated to drugs or tobacco, note its only refined sugars & omega 6 in large quantities I am concerned about, inventions of the last 100 years. Before being so sure take another look around our city centers and ask yourself what is going on if not addiction, large numbers of people deeply unhappy yet seemingly powerless to do anything about it, is a ‘lack of self control’ really the answer?

No you dont! But I do accept that this commonly is the attitude of posters on the forum. Arguments are polarised as posters shoot off to the extremes.

[LittleSister]

So I . . . have a fairly rigid rule that I don't each (much) between meals.

Me, too, but I do eat a lot of 'meals' every day!

 

[Zing]

Good link

It is a terrible article as I mentioned in my post. It implies we are the same a chimps and disregards the fact that our ancestors, the mainly vegetarian and occasional carnivore apes are a totally different animal from the mostly carnivore Neanderthals and Homo Sapiens having a very different digestive system.

8 years type 2. No drugs yet.....

Breakfast is eggs
Lunch tuna and avocado
Snack is almonds
Dinner. Hmmmm. At home meat and veg. So boat...... Meat and veg!
Another snack oatcakes and cheese.

 

[goonfresh]

I know my answer is a bit late for you, but I just wanted to share a bit of my experience. I often go for Greek yogurt with a handful of nuts or seeds—filling but quick. Sometimes, I'll have a couple of boiled eggs or an avocado, which is also great for healthy fats.

 

[goonfresh]

For me, canned bean salad, olives, and a bit of tinned tuna or sardines make it more substantial and are perfect for storage. Adding veggies like peppers or cucumbers makes it feel like a proper meal. I also pack some nuts and cheese as snacks for extra energy without the carbs.

Take a look at Sten Ekberg on Youtube - doctor and former olympic decathlete.

He's a brilliant man and a terrific guide. His advice isn't usually very hard to understand but often opposes the messages with which our food industry seems to have indoctrinated dieticians and doctors, to the detriment of the health of millions.

The incredible unsuitability of simple carbs for human consumption (actually, almost all carbs as far as I can see - I adore oats and wholegrain bread but they're catastrophic for blood-glucose control) is largely overlooked by our health chiefs and all beneath them. I suppose as a nation, perhaps as a world, we simply can't afford to feed everyone if their diet isn't dominated by cheap, highly processed, easily stored cereal and potato derived products.

The fact that several generations have grown to believe it's normal, natural and healthy to put them at the centre of their diet, is tragic.

...my current diet is cereals for b'fast, things like ryvita and cheese and buns and biccies for lunch, and a 2 course dinner with bread or spuds or pasta and a desert. The clue to what I like is in the name I have chosen.

I hope you're well, Birdseye, and I hope you've overturned those rotten carb-heavy preferences. I hope everyone who'd like to be slim, can do the same.
