borofergie said:I'm bored of saying this, but the "not enough exercise" argument for obesity isn't feasible either...
I burn about 200kcal per mile when I run. To burn off a single pound of fat I'd need to run at least 17miles, and not eat any extra food to fuel it. I'd have to run 250 miles on an empty stomach to lose a stone.
This doesn't happen. If you exercise, you get hungry, you refuel, and your metabolism slows down while you sit on the sofa for the rest of the evening, watching TV and having a snooze.

I would be interested to see the reaction from people who have not had to radically change their lifestyle due to disease (diabetes or anything else) and to see if they show more awareness now of what they eat.
Looking forward to the next 2 episodes!
phoenix said:Yes and no Stephen, there are all sorts of things that alter when you exercise more, increase your muscle mass and your BMR goes up.
Personally if I sit on the sofa I'll remain there, if I exercise then I'm more likely to do other things. (endorphins?) and I don't eat any more if I'm doing a 'normal mileage, say less than 20 miles a week. I can remember when I was younger taking home my sandwiches that I'd made for orienteering, often didn't want to eat them.
If I run or even walk any more than 20 miles a week I will lose more weight than the 1lb/ 3,400 calories used would suggest (I theoretically use less calories per mile than you do), probably at the rate of about 2lb a week.
At my maximum of about 40 miles a week and paticularly on a backpacking holiday than I eat more and still lose weight.
Why Calories Count said:The number of calories [expended due to exercise] are likely to add up to a small percentage of those required for basal metabolism. Their number is also small compared to the number of calories that most people expend in a day.
Why Calories Count said:This however does not stop food companies and government agencies from emphasizing physical activity as the primary strategy for losing or maintaining body weight. From a political standpoint, the advice to move more is much less threatening than advice to eat less. Moving more does not effect the economic interests of the food companies or any other powerful industry. In contrast, as we keep reminding you, simply eating less is bad for business.
noblehead said:Not seen it yet and will do so over the weekend, reading everyone's posts it seems that the programme is going over old ground and stating the blatently obvious
borofergie said:I've said before that the "low-fat" mantra is on very shaky ground. There isn't any credible scientific data that supports it, so it's good to see these ideas exposed in the mainstream media.

borofergie said:She has an interesting theory as to why the establishment continues to promote exercise as a weight loss strategy:

running maybe, and 40 mile is what I have done at a maximum and won't do again; walking yes, 20 miles a week is less than 3 miles a day. I'd rather be like the elderly people I know who are still able to go for a daily 3 or 4 k a day, but then the nearest shops are 8km and school was that sort of distance for most so they're used to it.I don't need to tell you that running, or walking 20-40 miles a week is not sustainable for anyone apart from dedicated athletes (not even with a Paleo rationale). There is evidence that this sort of exercise is deleterious to your health (hormesis
swimmer2 said:Sid's statement that (and paraphrasing Sid, sorry) - that if I eat more than I use I will get fatter - is a rather loaded statement, because whilst (with the caveats you've all given) it's basically true, it implies that it's my fault if I become obese. In fact this was the argument given by the lady on the programme who defended the US food companies. Even without the suggestion that sugar affects my brain, we are talking about a commodity that we require to live. If food production uses ingredients that damage our health across such a wide spectrum of food types and this is done for profit reasons, then even if the ingredients weren't addictive the practice couldn't be described as moral. Suggesting I don't eat ANY processed food is hardly helpful, since is very difficult (not to mention expensive) not to.
viviennem said:Reading over that last sentence - have I at last found the key to a miserable, overweight life of 40+ years constantly trying to lose weight, and failing. Hating myself. "I can't metabolise carbohydrate properly" ! Nothing else matters.
I wish someone had told me that when I was 15, instead of telling me to eat carbs all the time!
swimmer2 said:Well, as I said, I enjoyed and was informed by the programme.
If nothing else then it has stimulated another interesting discussion on here. Thanks Phoenix for an informed response to my rather naive question - there is clearly much more reading I have to do.

Sid Bonkers said:There is one other thing that was mentioned in last nights program that has until now not been discussed and that was 'snacking' or eating between meals, which is something that was never ever done when I was growing up. And nowadays a whole industry has developed to sell us stuff to eat between meals or to sell us things to eat 'on the go', there is now a Greggs or similar on every high street selling nothing but sandwiches, rolls and pastry items, sausage rolls, pies etc etc. Instead of the Cadbury's chocolate bar that I would get as a treat as a lad, today there are a million different chock bars and sweets that are there to tempt the passing consumer.
