Sorry, expend. An untintentional but amusingly appropriate mistake. Also, most of the masters I race with are very lean and fit (more so than me sometimes). The one's who aren't have generally taken a lot of time off the bike at some stage (reducing their energy expenditure but not necessarily their calorie intake).

Great post. People often don't realise that a negative energy balance is the most important factor in weight loss. 1000 kcal is 1000 kcal no matter the source.

2LAP, thanks for the heads up - I feel like I'm learning all the time on these boards, and thoroughly reading the posts from you, Ric, ACoggan and a few other well qualified people has been really helpful. Please jump on me when I get things wrong and thanks for all the great info.

A more general question: why are people religious about their diet? Vegans, vegetarians, atkins, high carb, low carb, zone, etc... and everyone's convinced that the logical explanation they've heard for the diet is also true. Research is ignored, or a hunch is taken to be a scientific fact. My favourite example is the diets that are based on blood type. Like, Type O+'s used to be hunters in a previous life, so they should eat meat. A- were farmers, they should eat grain. It's all just insane!

There's no increased risk of illness with glycogen depletion, and it increases CPT (carnitine palmityl transferase) activity, increasing fat loss, and the drop in insulin from lowering carb intake naturally inhibits alpha-2 receptors in the fat cells (a good thing).

A level of glycogen depletion is fine and we are all in this state most of the time. Complete glycogen depletion is not a good state to be in particularly when the shakes, halucinations and desire to sleep set in.

Exercise increases insulin sensitivity lowering insulin concentrations and some research is suggesting that exercise reduces any additional health risk from consumbing a very high carbohydrate diet. We could argue biochemistry all day, what about the effect of glycogen depletion on central fatigue? At the end of the day a negative energy balance is needed for weight loss irrespective of what is eaten.

The alternative to carb consumption (i.e. high fat consumption) is more concerning to me with high levels of circulating triglyceride rich lipoproteins. Particularly with a family history of heart disease.

Cyclists are constantly terrified they aren't getting enough carbs so many _overeat_ them, which is why we have fat masters syndrome and pros who don't even have a vein running up their biceps and fat covering their kneecaps when they stand up.

I think that some pro's and masters are fat because they eat too much and not that they eat too many carbs. Often retired athletes put on weight because they reduce their energy expendature, but don't reduce their energy intake to match.

in some cases, people are 'religious' about their diets due to their belief system (e.g. muslim people who eat halal meats, jewish people who eat kosher and vegetarians, vegans who don't wish to eat food products that have come from living creatures). i'm not however, suggesting that being vegetarian (etc) is a religious belief system though (such as e.g., judaism, christianity, etc).

on the other hand 'fad' diets such as Atkins, Sears, etc. are neither (religious or moral beliefs) and are really just errr fads.

I saw a rational for the blood type diet recently, very funny!!!!!!
Hope you had a good trip ric!

Sorry, yes, I'm not suggesting that there's anything wrong with religion per se. There are coherent arguments for all sorts of religious systems and their accompanying dietary regime. Reliogious philosophy is actually an area I'm pretty interested in, and I don't mean any disrespect to anyone's particular moral and religious way of viewing the world. I'm just suggesting that there is a cult-like fervour involved in certain fad diets. Religious is probably the wrong word.
