Weightloss for better survival chances

I am afraid I have learnt to be rather skeptical about "fashionable" diets like the Venus Diet that seem to be mostly hype but don't seem to offer anything new scientifically. So my answer to your question is "No". It is not a matter of vegetarian is more or less healthy than nonvegetarian diets To be healthy, a diet has to be an eating and exercise regime that helps you reach your ideal weight and then maintain it longterm. Which is what Valter Longo's fasting process does. He does recommend a plant-based diet, ie not carb based like most diets, and minimising carbs and keeping fat to a reasonable but lowish level. He includes some chicken, some fish, and a very little other meats if wanted. A big problem is that most diets actually reset your weight set-point higher: When you go onto a diet and then off it after reaching your goal weight, your weight drops down and then yo-yos back up again once you "stop dieting" and often end up weighing more than when you started. Unless you prevent it doing so by making lifestyle changes that allow you to keep the weight-change.

There was a very good study done into diets of cultures where people lived long and healthy lives. The diets varied from Massai diet which is blood, milk and meat, to Icelandic which is seabird's eggs, fish, seaweed and rugged vegetables, to Georgian which is yoghurt, cheese, milk, bread, whole grains, fresh vegetables. What they all had in common was that the things they ate were grown or caught locally (generally by themselves) and seasonally, were eaten fresh, and were not refined ie they ate almost all of it. They were caught in clean water or forests, grown on small lifestyle farms, without the use of the horrible pesticides and herbicides our massive monocultural farms use.

I think these things matter more than specific hyped up fashionable diet plans that may work to lose weight but do nothing to ensure you can keep it off for the next 5 years.

But that is just my view. You are entitled to yours, and whatever works to get you both healthy and a healthy weight that you can maintain should be good for your heart as much as the rest of you.
