Ride safe Comedian. One nasty stack and extended time off the bike will see you on your work mate's lite n easy portions, not to mention taking the bus.
In his excellent book Cycling Past 50, author Joe Friel speaks about the importance of Protein in one's diet. Everything below is based on an over 50's rider that is 'training hard' and he suggests .1 to .2 gm less for younger riders.

Joe says that an over 50's rider should be consuming .7 to .9 gm of protein per lb of bodyweight. Now at (say) 100kg = 220lb that would be about 175gm I would need to consume daily.
Then he illustrates the amount of protein in certain foods in a table on page 190 and said that half a chicken breast yielded 30gm of protein. Now, for me to consume 175gm protein daily, assuming my daily intake from other sources was as much as 75gm, I would need to be consuming one and a half chicken breasts each day.

Does that sound right?

NH&MRC science based guidelines for protein for adults doing intense exercise is 1.2-1.8g/kg body weight. Joe's recommendation is at the upper limit.
As a practical ready reckoner, below are % protein by weight for each food group, and $/100g protein:

- raw lean skinless animal flesh ~20%, $15 (for $30/kg cuts)
- mixture of nuts 15%, $13
- dry pasta 12%, $5
- bread products ~10%, $4
- whey protein isolate powder. >90%, $3
- raw rice ~7%, $2.86
- raw legumes like lentils and navy beands 20-25%, $2.50

Keep in mind excessive protein intake increases dramatically the risk of kidney stones, and calcium resorption from bones.
Excess meat consumption is converted to fat, a very expensive form of fat.
The non animal flesh foods above have ingredients apart from protein, which improves their cost benefit.

Thanks Pawpaw, what does "- raw lean skinless animal flesh ~20%, $15 (for $30/kg cuts)" mean?
12% protein in DRY PASTA?
Holy cow, how does one eat dry pasta?

Sorry disagree on the fruit juice as it concentrates fructose. Suggest fruit instead.

What kind of cereals are you suggesting?

raw = not cooked or dehydrated or otherwise changed from its original state.
lean = minimal fat
skinless = skin removed, mainly applies to chicken
animal = things that move with the help of muscles which humans eat
flesh = mainly muscles
~20% = the percentage of total weight that is protein = 20grams protein / 100 grams wet weight.
$15 = cost /100grams of protein, based on $30/kg cuts of meat


- the water you add to pasta to cook it doesn't have any macronutrients in it, and is essentially free so doesn't effect final comparative cost.
I used dry weight because these products are generally sold dry to reduce transport and storage costs and improve shelf life; and different people will add different amounts of water to eat them.

Mmm raw flesh. Do we get extra points for tearing it off the bones of an ainimal we have recently chased down and bitten to death. Which is a bit un-neighbourly, there being mostly pet dogs around here.

The Paleo Diet crowd would give you 100 points.
Though paleolithic people never lived in cities of 1,000,000+ so wouldn't have had as much competition for neighbor's pets.

$30/kg for meat?!?! You must be rich... ;)

Bit unrealistic... I buy very good quality, grassfed beef (whole rumps) for less than $10/kg. Skinless chicken fillets (breast or thigh) is usually less than $8/kg. Lamb is more expensive - but if you only buy it on sale, you'll get it at less than $15/kg.

That all changes the cost/benefit pretty dramatically.....

Cheers,
Abby

Just heard on a radio program where they talked about the fruits of today has been largely modified through selective breeding, typically resulting in significant increases in fructose content. As a result, one needs to watch out one's fruit intake and not consider them as zero or low calorie.

On my dietitian's advice, I average eating around 300 grams of animal flesh a week (any of beef, salmon, chicken, pork, lamb), so don't mind paying for premium free range product bought from a butcher. yes, chicken is cheaper but salmon is more expensive.

I understand Coles and Woolies price war includes meat.

Do you have to trim any fat off your cuts? We tried buying in bulk a few years ago, but found the quality wasn't all it was made out to be, and total cost (including deep freeze operation) did not warrant the exercise.

We get most of our red meat from one of the Superbutcher warehouses (Yatala or Eagle Farm). Its good stuff, and they have staff butchers that cut up the whole rumps, etc, for you on the spot. I usually get them to trim the fat off pretty hard. They get a bit surprised and say I'm losing some flavour - but the meat is actually very good (they are very clear about the provenance of their different cuts), so it always is delicious... The box freezer is working out pretty well for us (except for that one time I accidently turned it off - we won't go there...... :oops: )

Chicken is always from Coles/Woolies...

I hear you with salmon. Unfortunately, my two kids absolutely love it and would eat it 7 days/week if they could!! I haven't seen any 'decent' fresh salmon for less than $27/kg (even on special!). But I don't mind paying that for a once/week meal...

Cheers,
Abby

Not surprised at that either.

I've heard of people who exclude fruit from their diet because of the fructose. Probably a case of moderation.

I probably don't eat enough fruit as it is

And standard cuts of meat have more fat than 50 years ago, so probably a case of eating less.
And veges have less vitamins and minerals, so probably a case of eating more.

I am at 77.5 and targetting 75kg for this year (180cm with what my physio called a high muscle bulk build. Chunky) I certainly find I am fighting myself all the time. I am constantly obsessed with food. Thinking about it all the time. The day before a race is a free day, I can eat, drink etc what I like. I love that day. I dream of that day.

I'd apply Occam's Razor first, by checking data reliability.
Self monitoring of energy intake is notoriously unreliable, as are many bicycle computers that spit out Calories burned.
The temptation to eat more when exercising more, is overbearing for most, whether they accept it or not.

Here's the rub. It's been shown that (example statistics follow)

If a 30 y.o. male at 75kg can maintain their weight by consuming 8000kj per day, a 30 y.o. male that weighs 100kg that sheds 25kg by dieting may only be able to consume (say) 6500kj per day to maintain that weight.
Something has definitely changed. The body is trying to fight back to regain the fat deposit.
Now... could this be an evolutionary throwback where thousands of years ago human beings couldn't rely on regular meals.
Could it be that the the body desperately tries to regain fat deposits to ensure the body has stores of energy to see it through lean times?
Probably gobbledygook but an interesting thought.
