I know we discussed this in another thread (about Miss Js friend who restricts his diet, etc) but I could not find the thread. Anyway, I found this pertient on that subject: http://www.sciencenews.org/view/generic/id/50275/title/Amino_acid_recipe_could_be_right_for_long_lifeQuote:Long life may stem from a proper imbalance of dietary nutrients.
A new study in fruit flies suggests that the life-extending properties of caloric restriction may be due not only to fewer calories in the diet, but also to just the right mix of protein building blocks, called amino acids. The study, published online December 2 in Nature, may help explain some of the health benefits of restricted-calorie diets.
Coupled with other data, the new study should prompt researchers to reevaluate whether it is calorie count or the nutrient composition of a diet that is most important for regulating lifespan and health, comments Luigi Fontana of Washington University in St. Louis.
Caloric restriction — a diet that contains a minimal amount of calories while maintaining healthy levels of nutrients — has been proven to extend lifespan in fruit flies, worms, mice, dogs, baboons and other organisms. Nutritious, low-cal diets also improve health in people, but scientists don’t yet know whether such diets can extend maximal lifespan in humans.
There is a downside to living longer, though. Many animals on low-calorie diets shut down their reproductive systems. Female fruit flies, for example, don’t lay eggs when fed the calorie-restricted diets. The effect makes sense, says study coauthor Matthew Piper of University College London in England.

Anorexics (women) stop having periods. I wonder if there are cases of these diet restricters who end up crossing that line.

I try to keep my calorie count at around 1100, is that low enough to be considered a restricted calorie diet? I would think so, since the average diet is supposed to be around 2000. Nicole Kidman is said to only eat 900 cals a day- very tough to do even when you're eating only healthy foods. I'm very thankful for TVP products-they're great for keeping the cals low and are healthy, plus I like a lot of them. Of course, I do have my days when I will eat 3 slices of a Papa John's "The Meats" pizza- damn my friend who turned me onto that, its sooo good.

1,100 is rather resticted. Here's one way to determine: Quote:In order to be fit and healthy, we need to take a proper and balanced diet. By this, we mean a diet that not only has all the basic nutrients, in the requisite quantities, but also has the right amount of calories. The calorie requirements of an individual depend upon his age, gender, height, weight, genes, health, physical exercise, etc. However, one can calculate the calorie needs of a normal adult man by taking into consideration his Basal Metabolic Rate (BMR) and physical exercise. Let us know how to calculate calories per day for males.
Basal Metabolic Rate
The Basal Metabolic Rate (BMR) of a man is used to determine the minimum number of calories that is needed by him, to power his body while resting. In other words, BMR is the amount of energy that is used by the body to maintain the routine functions like heart beat, respiration, normal body temperature, etc. the BMR of an individual accounts for around 60-70 percent of his calories requirements. It is at its maximum at the age of 20 and thereafter, gradually starts decreasing.
Physical Exercise
The second major determinant of the calorie requirement of an individual, be it a man or a woman, is the amount of physical exercise undertaken by him. The amount of exercise you do is directly proportional to the amount of calories you burn. Thus, more physical exercise leads to the need for a higher amount of calories. In short, the people who undertake strenuous work will definitely need much more calories than those who don’t.
The Purpose
Your daily calorie requirement will depend upon the purpose behind it, namely weight maintenance, weight loss and weight gain. The calories needed for attaining one of these purposes will differ from that of the other. The amount of calories you need for losing weight will be low than those you need for maintaining weight. While, the calories needed for gaining weight will be the highest. For example, 3500 calories make up one pound of weight. So, if you want to increase your weight by one pound in a week, you will be required to eat 3500 more calories than the usual.
Harris-Benedict Formula
In Harris-Benedict formula, first the Basal Metabolic Rate (BMR) of a man is determined. This is done after taking into consideration his height, weight, age and gender. Thereafter, taking into account the number of calories he burns by exercising, the BMR calorie needs are increased. With this, you get the total calories needed by him. The Harris-Benedict equation for calculating Basal Metabolic Rate is:
66 + (13.7 x weight in kilos) + (5 x height in centimeters) - (6.8 x age in years)
After calculating the BMR, you have to multiply it with the appropriate activity multiplier. This determines the exact calorie requirements of a man. The Activity Multiplier is:
1.2 (for those who do little or no exercise)
1.375 (for those who do light exercise/sports 1-3 days a week)
1.55 (for those who do moderate exercise/sports 3-5 days a week)
1.725 (for those who do hard exercise/sports 6-7 days a week)

Yes, I also recall that earlier thread on caloric restriction. I read in the San Fran Chronicle a while back that there is a whole society (more like cult?) of people who live like this. And perhaps they share recipes for things like: Festive New Year's Eve Distilled Water!" OR maybe "Blanched Carrot Shavings (only TEN) for Xmas Dinner! OR "Tweezer-Sized Meatless Meatballs - Made of Styrofoam!" I get downright GRUMPY when I read about this kind of life-extension philosophy. For the most part, the laboratory tests are done on tiny creatures. A baboon is at least a fraction of our size, but still: SMALLER. So that makes me wonder how the results of such experiments can even be extended to US! I am no pipsqueak at 5'8". No one would accuse me of being anorexic, but I maintain my weight at 132 come HELL or HIGH WATER. I just adjust some component of my food intake/exercise ratio. And I deny myself nothing in the food department. But at day's end, I've probably consumed 1800-2000 calories. I could no more give up chocolate, wine, pasta, nuts or other caloric foods than I could spin gold out of straw. And what's the point of living to 127 if one is a shriveled up, grumpy, blind, deaf, arthritic old coot? Is that what these calorie-restricted folks want to do? Good. Send them all to the moon - a gravity-free stroll is easier on the knees. Quality life. That's what counts.

I'm with you, Bug. Now that I finally found Haagen Dazs in butter pecan, life has improved dramatically. I think the couple of spoonsful that I have (from one of their pint containers) each night is probably 1,200 calories--but, I am not complaining.

Well, my friend does not really count calories but he KNOWS he restricts them and restricts them by developing a distaste for many foods. Like he's not going to eat ice cream, white bread, stuff with processed fats or processed foods or anything like that. His mainstays are; oatmeal, kale and sardines. He eats other foods but eats those 3 things each day.

I think moderate calorie restriction is a good thing- most people eat far too much of the wrong things. Even switching to low caloric density whole foods and avoiding anthing processed should give the average person significant calorie restriction. I am very much against extreme caloric restriction- the bare minimum an adult needs per day are 1200 calories to prevent the body from lowering it's BMR and catabolizing its lean tissue. People who consume less than this (or less than their minimum caloric intake based on multiple factors) will lose muscle and water and end up with a higher percentage of body fat. I am 26, 5'7" and about 115lbs and typically consume between 1500-1700 calories a day to maintain my weight if I am not working out very hard. If I am working out hard, I lose weight even at 1700 calories a day. And of course this isn't even touching on all the other factors going on in terms of a healthy diet- calories are really just a very small portion of the big picture.

Ryan, what are TVP products? I broke my foot and can't workout so given the calorie restriction data I will probably be dead in about 45 minutes.

Is that soy products? I love soy, love the soy burgers, edamame.
Sorry to hear about your foot, Sam!

It was so funny today as I was with his brother at a cultural event thing. He brought his 'lunch' which was a few carrot shreds and red pepper pieces, a few sardines and a handful of leaves. He's RAIL THIN. Someone offered him some cheese crackers and he told them he was 'watching his diet' and all LAUGHED. I told everyone; 'Nick eats like a New York model' and if they thought he was over the top, they should see his brother who is even more strict as to what he eats. Then he was pointing out how his pants were almost falling down and he needed to find some suspenders. Like that's the case because he's so thin and there is little to hold his pants up. LOL. He's funny though. At the lake, he struggles to pinch like one little MILLIMETER of skin and calls it his "love handles". His brother thinks he 'eats too much' because daily he 'pigs out' on 3 corn chips--yes ONLY 3 corn chips which constitutes his 'pig out' session. LOL He does not have any health problems though. His cholesterol is very low and he's 60. Mine is high so maybe I need to follow his type of eating plan.

sam wrote:Ryan, what are TVP products? I broke my foot and can't workout so given the calorie restriction data I will probably be dead in about 45 minutes. Texturized veggie protein. Some are soy based, others are tempeh, I don't know that much about it except that I like the Lightlife brand. It's not for everyone, some people hate it. I think the "ground beef" works if you use it in a sauce- like a pasta sauce or something. I really like to make sloppy joe's with it- using the Manwich sauce and then I add my own diced onions, and peppers to it. I think it tastes pretty much the same and definitely close enough considering it's low cal, low fat, and high protein. I like to make my own pizza's using pita bread, pizza sauce, and I will add their pepperoni slices (I HAVE to crisp them up in the toaster oven first though), then a small amount of cheese. They don't really have that much taste, but add a lot of protein, so it's worth it to me. I have yet to find a soy/veggie hot dog that I like- if anyone knows of one, let me know. I'm not a vegetarian, but I eat these products for the low cals/low fat/high protein combo- they ain't cheap though.

Thanks Ryan. Not sure I could do TVP. I don't cook (not even a Manwich although I love that name) and convincing my husband to cook something with TVP would be impossible.
After 2 weeks out of the gym I worked with a trainer yesterday. I was in an area of the gym where everyone looked like they were older than my parents because I had to sit down for everything. Enjoy your workout (envy) and your hot new face.

I would avoid TVP and other refined, non-organic or geneticaly modified soy products. I am not sold on all the "health benefits" of soy in general. If you want to include soy in your diet, stick to organic non GMO fermented soy, such as tempeh or miso.

I think there's definitely something to them in terms of promoting longevity. But I would waste away to nothing and it would be very unaesthetic, so I eat about 2,800 calories a day. Good think I burn those calories!

Just got back from dinner with friends, one being the 'calorie restriction' guy. Man--he was cutting the turkey in like flimsy 1mm slices and only gave me a little bit saying I would live longer if I did not eat the large chunk I wanted from that turkey. Saved by the bell: The phone rang, he had to answer it and I cut myself a BIG chunk of the turkey and ran with it to the table before he could see.

There were about 8 guests there and it was a small (maybe 12 lb turkey). He cut up like only 1/2 of the turkey breast for 8 people. The calorie restriction thing (food restriction) is from a Puritan ethic. He comes from a long line of Puritans and does not believe that ANY DAY of the year should be one where peope 'indulge' themselves on food. Well, at least he attended the dinner. His brother stayed home to do his X-mas FASTING. LOL
