“…This variability depends upon several factors such as sex, age and, in particular, BMI. It has been consistently suggested that under-report increases with increasing BMI (Kretsch et al, 1999) therefore a 7 17% misreport represents a reasonable degree of inaccuracy, in a population of morbid obese subjects. Mis-report quite probably occurs also after surgery; however, it is difficult to evaluate its extent, because of the negative energy balance conditions; furthermore, the occurrence of malabsorption and=or vomiting, although limited, could reduce the significance of the relationship between energy intake and body weight loss.…”

Objective: The gastric bypass-induced quantitative and qualitative modifications of energy intake (En In, kcal=day) and their impact on body weight (bw) loss were evaluated. The factors influencing energy intake and body weight loss were also investigated. Design: Longitudinal study. Setting: University Hospital of Geneva. Subjects: Fifty obese women undergoing a Roux-en-Y gastric bypass. Results: The reduction of EnIn was significantly related to bw loss expressed either in kg or as percentage correction of excess bw (P < 0.01 for both), whereas the post-operative modifications of diet composition did not play a role. Age and initial bw significantly influenced bw loss (P < 0.0001 and P < 0.001, respectively), as shown by multiple regression analysis. Patients were divided into four sub-groups according to their age (under or over 35 y) and initial bw (under or over 120 kg). ANOVA showed that under 35-y-old subjects reduced their EnIn significantly more than their older counterparts having similar bw (P < 0.02 and P < 0.05); consequently, bw loss, expressed in kg, was significantly (P < 0.0001 and P < 0.0005) larger in younger patients. Subjects with an initial bw over 120 kg lost significantly (P < 0.001 and P < 0.02) more weight as compared to patients with a smaller degree of obesity (under 120 kg) and similar age. Conclusions: Gastric bypass-induced body weight loss is mainly due to the reduction of EnIn, whereas the qualitative modifications of the diet do not play a role. Younger subjects have a greater capacity to reduce EnIn and, therefore, lose more weight. Pre-operative high degree of obesity leads to a larger weight reduction, probably because of a greater energy deficit.

“…By use of the doubly labeled water technique, energy expenditure has been precisely measured and compared with food records. 26,27 Underreporting by 10% to 20% of calories is typical, with obese and formerly obese individuals, especially women, underreporting to a greater extent. There is not yet a way to know whether some types of foods are more or less underreported than others.…”

Abstract-We previously reported that high density lipoprotein cholesterol (HDL-C) decreases more in hypercholesterolemic (HC) women than in HC men ingesting an National Cholesterol Education Program (NCEP)Step II diet for 6 months. We examined these subjects to determine whether the differential HDL-C reduction persists after 12 months and whether it is associated with decreased HDL 2 -C and apoprotein A-I. Subjects were screened from an industrial workforce and were defined as HC if 2 low density lipoprotein cholesterol measurements were Ն75th percentile or defined as combined hyperlipidemic (CHL) if triglycerides were also Ն75th percentile. The subjects were then taught the NCEP Step II diet in 8 weekly classes and counseled quarterly. Seventy-three HC and 92 CHL women (mean ages 43 and 44 years, respectively) and 112 HC and 106 CHL men (ages 45 and 41 years, respectively) were studied. All groups reported similar total fat (24% to 26% kcal) and saturated fat (7.1% to 7.9% kcal) intakes at 1 year. HDL-C decreased 7.6% in HC women (PϽ0.01), exceeding the nonsignificant 1.3% decrease in HC men (Pϭ0.000). HDL 2 -C decreased 16.7% in HC women (PϽ0.01) compared with the nonsignificant 0.5% increase in HC men (Pϭ0.000). In CHL women and men, HDL-C decreased 3.5% and 3.9% (both PϽ0.01); HDL 2 -C decreased more in women (7.1%, PϽ0.01) than in men (4.3%, a nonsignificant difference). Apoprotein A-I decreased significantly (5.3%, PϽ0.01) in HC women only. Plasma triglycerides were unchanged. Low density lipoprotein cholesterol and weight changes were not different among the 4 groups. HDL-C, HDL 2 -C, and apoprotein A-I levels decreased more in HC women than in HC men after following the NCEP Step II diet for 1 year, continuing a trend observed with HDL-C at 6 months. The total HDL-C and HDL 2 -C reductions narrow the baseline differences between men and women by 50%. Whether this reduction impacts women's protection from cardiovascular disease deserves future study. Nonetheless, the results point to sex-based differences in intrahepatic glucose and fatty acid metabolism linked to alterations in HDL formation and removal. Key Words: hypercholesterolemia Ⅲ combined hyperlipidemia Ⅲ HDL cholesterol Ⅲ apoA-I Ⅲ low fat diet H eart disease is the most common cause of death in women and men in the United States. 1 Hypercholesterolemia is a major modifiable cardiovascular disease (CVD) risk factor in both sexes. [2][3][4] Dietary modification to lower LDL cholesterol (LDL-C) is the primary strategy for the population-based reduction in CVD risk. 5,6 The National Cholesterol Education Program (NCEP) recommends reducing saturated fat intake in 2 steps, to Ͻ10% of calories (step I) and Ͻ7% of calories (step II), in the initial management of individuals with hypercholesterolemia, regardless of sex, before instituting pharmacological measures. 6 Recently, we reported sex-equivalent reductions in LDL-C but significantly greater HDL cholesterol (HDL-C) reductions in hypercholesterolemic (HC) women compared with men 6 months after inst...

Objective: To examine relationships between the ratio of energy intake to basal metabolic rate (EI/BMR) and age and body mass index (BMI) among Japanese adults. Design: Energy intake was assessed by 4-day semi-weighed diet records in each of four seasons (16 days in total). The EI/BMR ratio was calculated from reported energy intake and estimated basal metabolic rate as an indicator of reporting accuracy. Setting: Residents in three areas in Japan, namely Osaka (urban), Nagano (rural inland) and Tottori (rural coastal). Subjects: One hundred and eighty-three healthy Japanese men and women aged $ 30 years. Results: The oldest age group ($ 60 years) had higher EI/BMR values than the youngest age group (30 -39 years) in both sexes (1.74 vs. 1.37 for men; 1.65 vs. 1.43 for women). In multiple regression analyses, age correlated positively (partial correlation coefficient, b ¼ 0.012, P , 0.001 for men; b ¼ 0.011, P , 0.001 for women) and BMI correlated negatively (b ¼ 2 0.031, P , 0.001 for men; b ¼ 2 0.025, P , 0.01 for women) with EI/BMR. Conclusion: Age and BMI may influence the relative accuracy of energy intake among Japanese adults. . In particular, underreporting of energy intake is a serious threat to the validity of self-reported dietary assessment data. Studies using the doubly labelled water technique as an external biomarker of energy intake not only reveal underreporting of energy intake, but also identify the subject characteristics and factors associated with underreporting 3,4 . Moreover, other studies using the ratio of energy intake to basal metabolic rate (EI/BMR) as an alternative approach to identify the low energy reporters have shown similar results 5,6 . Most studies found a higher proportion of underreporting among women and older subjects 7,8 . Moreover, underreporting of energy intake was common among obese subjects 9 -11 , but was also observed in non-obese subjects 12,13 . Other factors such as body image, health consciousness, social desirability, educational level and smoking status also affected reporting accuracy 2,14,15 . However, all of these studies were conducted in Western countries. The only study conducted in Japan showed a significantly negative correlation between BMI and EI/ BMR among women aged 18 -20 years 16 . Thus the purpose of the present study was to examine the relative accuracy of self-reported energy intake among various age ranges in the Japanese population.
