Dietary Advice

From this Guardian article:
There’s no conclusive evidence a morning meal makes you lose weight and feel great, but the idea that breakfast is the most important meal of the day is widely ingrained. This is largely thanks to the efforts of grain companies. Kellogg’s, for example, funded an influential study that linked breakfasting on cereal with lower BMI. And The Quaker Oats Center of Excellence financed research showing that a daily breakfast of porridge reduces cholesterol.
Many people are very adamant that eating breakfast is incredibly important. Indeed they seem to think I'm completely lacking in common sense when I question it. I hope they are not relying on research funded by those with vested interests. I've read that such research is of no value whatsoever and should be disregarded. And it wasn't someone merely just claiming it. They backed it up with statistics which seemed to me convincing at the time. Unfortunately I'm unable to recollect the source!

Indeed it is claimed by many that we ought to eat breakfast regardless of whether we're feeling hungry. Likewise many people claim we shouldn't wait until we are thirsty before we drink since we are already dehydrated by that point. But it seems strange to me that we should simply ignore our bodily signals. Surely one should eat when one is hungry only? And only drink when we are thirsty?

Presumably non-human animals do not eat and drink when they're not hungry and thirsty? Do they have an obesity epidemic? Er . .no. animals apart from our pets never get fat! Not even when they're in an environment where there is an abundance of food. Do they suffer adverse health consequences since they don't eat when not hungry and drink when not thirsty? Do they get more cancer, suffer more heart disease, dementia etc more frequently than we humans do? I don't think so.

Lack of exercise in the UK

Apparently in the UK (where I live) 48 per cent of women and 42 per cent of men are too unfit to run for a bus. And 47 per cent of women felt they could run up to just half a mile, while one in five said they could only manage 100 metres.

From here:

The BHF called the figures 'worrying', warning heart and circulatory disease affects around seven million people in the UK and is responsible for around 155,000 deaths each year - an average of one person every three minutes.
It's not worrying, on the contrary, it's good news.

The figures for circulatory disease are a given. They exist for the lifestyles we have at the present moment. So, if we are to believe these figures, this includes many people who do little or no exercise. This would seem to suggest if most people attempt a moderate amount of exercise these figures might reduce.

On the other hand, if these figures existed despite most people doing moderate amounts of exercise, this would be more of a puzzle and the solution would be more complex.

The charity has launched a new fundraising campaign called MyMarathon, which urges the public to run the marathon distance of 26.2 miles over the course of a month.
That's just about a mile a day, which is totally unrealistic. People will just not do any exercise at all rather than do that. More realistic advice would be to run 0.5 miles (~1km) once every 5 days or so. People might keep that up over the long term.
