Memory issues are a common feature of mild cognitive impairment. It is believed that much of memory function is the domain ofpart of the brain known as the hippocampus (there are two of these, […]

Five things I do now that I didn’t do five years ago

I sometimes think that some people imagine I live some perfectly healthy existence. While my lifestyle might be tons better than it was when I was a young adult, say, at least some of my lifestyle habits vary a bit depending on things like environment (I travel quite a lot), workload and priorities. There is […]

The Calorie Myth by American author Jonathan Bailor

Regular readers of this blog will know that I’m not particularly one for endorsement, though I do sometimes recommend specific products that I believe have particular merit, including books. Recently, I became aware of a book which I think is a valuable contribution to the area of nutrition and weight control. Entitled The Calorie Myth, […]

Exercise – when less can be more

I regard myself as quite an active person, but the intensity or volume of the exercise I take is nothing like it once was. For extended spells during my childhood and early adulthood I was a ‘keen’ runner. I participated in athletics and cross-country running at school, and continued running afterwards too. At some points, […]

Evidence suggests one form of exercise might actually suppress appetite

While I am an enthusiastic advocate of exercise, I am sometimes keen to dispel the idea that it helps the ‘pounds drop off’. Actually, the bulk of the evidence does not support exercise as a particularly effective tool for weight loss. Somehow, I think people are wising up to this now. For instance, I’ve had […]

Regular walking found to boost memory in those with ‘mild cognitive impairment’

‘Mild cognitive impairment’ describes a reduction in brain function that is not advanced enough to be described as ‘dementia’. It’s usually described via psychological testing. As yet, there is no recognised medical treatment for it. That doesn’t mean, of course, that nothing can be done about it, and in fact some recent evidence suggests that […]

Exercise found to improve ‘fat genes’, but what about its effect on actual fat?

My eye was caught yesterday by this report of a study into the effects of exercise on fat tissue. In the study, 23 overweight and healthy men engaged in a 6-month programme of exercise. The recommendation was for three, 1-hours sessions per week (1 cycling/spinning and 2 aerobics sessions). In the final analysis, the individuals […]

How our beliefs about what controls our weight may actually affect our weight

A couple of weeks ago I was talking to a lady who expressed the wish to lose weight. By her own account she was some 20 kgs heavier than she was many years ago when she was a competitive athlete. She worked full time, had a family and little time for exercise. Her view seemed […]

Statin found to largely negate the fitness benefits of exercise

A major motivator for many to take exercise is the desire to ‘get fit and healthy’. Regular exercise induces changes that can increase things like strength and endurance. One particular adaptation to exercise concerns increased numbers of tiny structures called mitochondria (my-toe-con-dree-ah) in the cells. Most of our energy needs are met by the metabolism […]

Is walking as healthy as running?

I’ve seen this week a few reports of a study which compared the potential effects of running and walking on a variety of health markers and outcomes including blood pressure, diabetes and heart disease. The study followed about 33,000 regular runners and about 16,000 regular walkers over a period of about 6 years [1]. For […]
