Kathrynne, Your "pizza, beer, and ice cream diet," works only if you have your tongue in your cheek. The diet would be much more effective if the beer were frozen. Then your body would lose the heat of melting the beer (4.185 x 6009 x 18 calories per gram). This heat is much larger than the heat that raises the temperature of the water from 32 F (or 0 C) to body temperature. Eating frozen beer would be the best way to lose weight. But, you were just testing us. A calorie (with a small c) is the amount of heat to raise one gram of water one degree Celsius. A Calorie (with a big C) is a kilocalorie, that is 1000 calories. It is the (big C) Calorie that people mean when they say that there are 4 Calories per gram of carbohydrate and 9 Calories per gram of fat. If you do the arithmetic with these numbers you will find that the frozen beer does not come anywhere near making up for the pizza and ice cream. You will have to get by on just beer alone. Baldwin, 63/4 7x25/100 carbi/levo-dopa, 5 mg Eldepryl per day [log in to unmask] ---------- From: Kathrynne Holden, MS,RD Sent: Tuesday, October 21, 1997 8:38 AM To: Multiple recipients of list PARKINSN Subject: The cold facts Dear friends, I found this on a list for dietitians, but it clearly applies to PD: ************************************************************** As we all know, it takes 1 calorie to heat 1 gram of water 1 degree centigrade. Translated into meaningful terms, this means that if you eat a very cold dessert (generally consisting of water in large part), the natural processes which raise the consumed dessert to body temperature during the digestive cycle literally sucks the calories out of the only available source, your body fat. For example, a dessert served and eaten at near 0 degrees C (32.2 deg. F) will in a short time be raised to the normal body temperature of 37 degrees C (98.6 deg. F). For each gram of dessert eaten, that process takes approximately 37 calories as stated above. The average dessert portion is 6 oz, or 168 grams. Therefore, by operation of thermodynamic law, 6,216 calories (1 cal./gm/deg. x 37 deg. x 168 gms) are extracted from body fat as the dessert's temperature is normalized. Allowing for the 1,200 latent calories in the dessert, the net calorie loss is approximately 5,000 calories. Obviously, the more cold dessert you eat,the better off you are and the faster you will lose weight, if that is your goal. This process works equally well when drinking very cold beer in frosted glasses. Each ounce of beer contains 16 latent calories, but extracts 1,036 calories (6,216 cal. per 6 oz. portion) in the temperature normalizing process. Thus the net calorie loss per ounce of beer is 1,020 calories. It doesn't take a rocket scientist to calculate that 12,240 calories (12 oz. x 1,020 cal./oz.) are extracted from the body in the process of drinking a can of beer. Frozen desserts, e.g., ice cream, are even more beneficial, since it takes 83 cal./gm to melt them (i.e., raise them to 0 deg. C) and an additional 37 cal./gm to further raise them to body temperature. The results here are really remarkable, and it beats running hands down. Unfortunately, for those who eat pizza as an excuse to drink beer, pizza (loaded with latent calories and served above body temperature) induces an opposite effect. But, thankfully, as the astute reader should have already reasoned, the obvious solution is to drink a lot of beer with pizza and follow up immediately with large bowls of ice cream. We could all be thin if we were to adhere religiously to a pizza, beer, and ice cream diet. -- Kathrynne Holden, MS, RD Editor-in-Chief, "Spotlight on Food--nutrition news for people 60-plus" http://www.fortnet.org/~fivstar and NUTRITION TOPICS copy-ready handouts http://www.dietetics.com/class/fivstar/ Tel: 970-493-6532 Fax: 970-493-6538
