Evaluation of the program by the physician • The match between the program and the consumers • The soundness and safety of the program: • Assessment of physical health and psychological status • Attention to diet and pharmacotherapy • Attention to physical activity • Program safety • Outcome of the program • Long-term weight loss • Improvement in obesity related comorbidities • Improved heath practice • Monitoring adverse effects that might result from the program
Caloricrestriction • Normal caloric intake 20-25 calories for each Kg of the body weight or • According to Harris-Benedict equation: For males RMR= 66.4+ 13.8 W + 5H – 6.8A For females RMR= 665+ 9.6W+ 1.8H – 4.7A W=weight (kg), H = height (cm), and A= age (yr) e.g. weight : 120 kg H= 175 A=35 RMR= 66.4 + 13.8(120)+5(175) – 6.8(35)=2359.5 • Less than 500 calories deficit per day➞ weight loss of .5 Kg per week
Energy Density • Definition Amount of energy in a given weight of food (kcal/g) • For the same amount of energy ,a greater weight of food can be consumed when the food is low in energy density than when its energy density is high Barbara j ,et al. J Am Diet Assoc.2005;105:S89
Glycemic Index • Jenkins and his collegues developed the GI. • The GI for a food was defined relative to a standard food (glucose or white bread). • Over a 2-hour period, the area under the glucose response curve after consuming 50 grams of carbohydrate from the test food was compared with the area under the glucose response curve after consuming 50 grams of carbohydrate from the reference food. • Both levels were given as the difference from fasting blood glucose levels . • The tests have been done in both healthy people and people with diabetes.
Jenkins and his colleagues have proposed that • All carbohydrates are not equivalent and that the rate of absorption of carbohydrate foods into the bloodstream is a critical factor in hyperinsulinemia. • Slowly absorbed foods would be beneficial because they trigger less of a rise and fall in blood glucose and, thus, less of a rise and fall in insulin levels
American Society for Clinical Nutrition, has noted that a number of diet strategies exist for weight loss and that different individuals may find different strategies useful. • Although they do not specifically endorse either the GI or energy density as methods for choosing foods, they have noted that both have some support in the literature and that further research into them is warranted • Klein, S, Sheard, NF, Pi-Sunyer, X, et al (2004) Weight management through lifestyle modification for the prevention and management of type 2 diabetes: rationale and strategies.
