Dr Briffa's Blog - A Good Look at Good Health
A health-focused blog that makes sense of science, and offers accurate, trustworthy and practical advice about all aspects of healthy living.
Obesity is essentially unknown in populations that live a traditional ‘hunter-gatherer’ way of life. As is well recognised, it’s different in Westernised populations. Why? Well, one theory, at least, is that hunter-gatherers are much more active, and are burning off more calories than their Western counterparts, which affords them the ability to maintain health weights. [...]
Last week, one of my blog posts featured a letter which highlighted the relationship between television viewing, sleep and body weight. Television viewing is associated with increased risk of obesity, and this association may be due to the tendency for people to eat more as a result of falling prey to TV advertising as well [...]
A few weeks back I wrote about a study regarding what is often termed ‘high intensity intermittent exercise’ (HIIE). As it names suggests, this form of activity involves blasts of explosive exercise (such as sprinting or cycling) interspersed with periods of much less intense effort. The study I wrote about revealed HIIE to improve running speed in [...]
Six years ago I decided to dramatically reduce the amount of time I spent watching TV, and this single intervention (I believe) had a dramatic effect on my life. It liberated a significant amount of time that I could devote to perhaps more useful and rewarding pursuits. You may be thinking that I’m referring to [...]
I’m a bit cynical about the food industry’s attempts to help us lower our weight and trim our waistlines through tactics such as giving us smaller portion sizes or taking some fat out of a highly processed foods to replace it with sugar or something else of dubious value. I recently wrote about this here after [...]
Last Friday I was invited on to the BBC Radio 4 consumer programme You and Yours to discuss the UK Government’s scheme to shave off 5 billion calories from our daily intake (about 83 calories a person, apparently), and the role the food industry has here. You can listen to the broadcast here (starts at [...]
I want to preface this post by saying I am a huge advocate of exercise, preferably outside if weather conditions allow. I believe there are physical and psychological benefits to being active, and I even ‘walk the talk’: although I do not run any more, I am a notorious walker and swim regularly. I also [...]
Last week I was aboard a cruise liner in the Caribbean. I had a lot of fun but was primarily there to participate in a kinda conference organised by low-carb advocate Jimmy Moore. I was privileged to share the stage with some very lovely and inspiration speakers, among them the US cardiologist Dr William (Bill) [...]
The need for regular meals are a regularly-occurring feature in healthy eating and weight loss advice. I used to believe this myself. But in the last year or two I’ve had to reconsider my thinking on this on this on the basis of my own personal experience as well as people I’ve worked with clinically. [...]
One could argue that our health is the product of factors that can be genetic (inherited) or environmental (including diet and activity). Body weight, for instance, will usually ultimately determined by these two major factors. There is no doubt that some people inherit more of a tendency to be heavier than others. Some people do [...]
