For benzene at 25°C this becomes AU = 33,900 - 8.314 (298) = 31,400 J mol". The molar volume of a compound is given by V° = (molecular weight)/ (density). For benzene at 25°C, this becomes V° = 78.0/0.879 = 88.7 cm mol". Tlie cohesive energy density is simply the ratio AUy/V°, but in evaluating this numerically, the question of units arises. By convention, these are usually expressed in calories per cubic centimeter, so we write... 

A1 tern an and low molecular weight alteman fractions from F mesenteroides B-1355 are being studied as hulking agents for reduced calorie foods (124), and dextran oligomers containing a(l — 2)-linkages have been proposed for similar appHcations (211).

Those with a normal diet take in food in the forms of carbohydrates, fats and proteins. Because it has a low water content and produces so many ATP molecules, fat yields 9.3 Calories per gram while carbohydrates and proteins yield less than half as much (4.1 and 4.3 calorics per gi-am respectively). Thus, we get a huge number of calories from a small quantity of fat eaten. The average person in the United States has a diet with 50 percent of the calories in the form of carbohydrates, 35 percent in the form of fat and 15 percent in the form of protein. We need about 1 gram of protein per kilogram of body weight per day to replace body proteins that are broken down. A 70 kg person... 

The total number of calories a person needs each day is the sum of the basal requirement plus the energy used for physical activities, as shown in Table 29.1. A relatively inactive person needs about 30% above basal requirements per day, a lightly active person needs about 50% above basal, and a very active person such as an athlete or construction worker may need 100% above basal requirements. Some endurance athletes in ultradistance events can use as many as 10,000 keal/day above the basal level. Each day that your caloric intake is above what you use, fat is stored in your body and your weight rises. Each day that your caloric intake is below whatyou use, fat in your body is metabolized and your weight drops. 

As in the last section, we can estimate the uncertainty in q by considering the worst possible combination of uncertainties. Suppose the weight is actually 343 grams and At is actually 28.8°. Then the product would be below 10,074.0 calories. But perhaps the weight is actually 347 grams and At is actually 29.6°. Then the product would be above 10,074.0 calories. These extremes determine the uncertainty in the product ... 

Ephedrine by itself has been shown to be ineffective as a weight-loss treatment. Ephedrine combined with either caffeine or aspirin is effective. The effect appears to stem from a combination of appetite reduction and avoidance of the metabolic rate decrease usually associated with a reduced-calorie diet. 

Total calories Adjust caloric intake to maintain desirable body weight and prevent weight gain... 

During these MNT educational and planning sessions, patients receive instructions on appropriate food selection, preparation, and proper portion control. The primary focus of MNT for patients with type 1 DM is matching optimal insulin dosing to carbohydrate consumption. In type 2 DM, the primary focus is calorie reduction to achieve weight loss. 

Moderate weight loss has been shown to reduce cardiovascular risk, as well as delay or prevent the onset of DM in those with pre-diabetes. The recommended primary approach to weight loss is therapeutic lifestyle change (TLC), which integrates a 500 to 1000 kcal/day reduction in calorie intake and... 

Goal calorie and protein requirements Perform a subjective global assessment Take into consideration the patient s current clinical status, diagnoses, medications, etc. Total daily calories -25-30 kcal/kg per day, or -1 500-1 800 kcal/day Protein -1.5-2 g/kg per day of ideal body weight (-89-11 8 g protein/day) This patient has sepsis, diffuse peritonitis, and recent surgical procedures, target -1800 kcal/day and -11 0 g protein/day... 

It is debatable whether obesity is related to total calorie intake or composition of macronutrients. Of the three macronutrients (i.e., carbohydrate, protein, and fat), fat has received the most attention given its desirable texture and its ability to augment the flavor of other foods. Food high in fat promotes weight gain in comparison with the other macronutrients because fat is more energy-dense. When compared with carbohydrate and protein, more than twice as many calories per gram are contained in fat. In addition, fat is stored more easily by the body compared with protein and carbohydrate.23... 

There is a simple equation that explains how a person s body maintains its weight. To maintain a steady body weight, the amount of energy a person takes in (the number of calories he or she eats) must equal the amount of energy the person uses (how many calories he or she burns). 

Decreases in physical activity can lead to weight gain. Ultimately, all the calories you eat are not utilized, or burned off. Calories that are not utilized are stored as fat tissue, which...
