“…132,133 Yet, most nutrition research fails to measure any form of energy expenditure or objectively quantify PA. Currently, there is only one manuscript of which we are aware that uses the NHANES objectively measured PA data to directly assess nutrition-related outcomes 134 and no nutrition-related publications that include the NHANES treadmill CRF data in analyses. The lack of publications may be due to the fact that only two waves in the 40+ year history of the NHANES include objective measures of PA, and despite the widespread acknowledgment of the necessity of daily PA for health and well-being, it is routinely discounted by governmental public health funding agencies.…”

“…Given that PA and CRF are major determinants of health, 123,124,134,136-138 and that PA is the only major modifiable determinant of TEE and nutrient-energy partitioning (i.e., the metabolic fate of the foods we consume), 6,125-131,134 it is clear that both PA and CRF must be objectively measured and controlled for in analyses if the health effects of any dietary intervention are to be examined accurately. Yet because PA questionnaires suffer from many of the same systematic biases 75,139,140 and inadmissibility issues as M-BM, the failure to objectively measure PA and control for it in analyses renders health inferences from previous nutrition epidemiologic studies moot.…”

The Scientific Report of the 2015 Dietary Guidelines Advisory Committee was primarily informed by memory-based dietary assessment methods (M-BM; e.g., interviews, surveys). The reliance on M-BM to inform dietary policy continues despite decades of unequivocal evidence that M-BM data bear little relation to actual energy and nutrient consumption. M-BM data are defended as valid and valuable despite no empirical support, and no examination of the foundational assumptions regarding the validity of human memory and retrospective recall in dietary assessment. We assert that uncritical faith in the validity and value of M-BM has wasted significant resources and constitutes the greatest impediment to scientific progress in obesity and nutrition research. Herein, we present evidence that M-BM are fundamentally and fatally flawed due to well-established scientific facts and analytic truths. First, the assumption that human memory can provide accurate or precise reproductions of past ingestive behavior is indisputably false. Second, M-BM require participants to submit to protocols that mimic procedures known to induce false recall. Third, the subjective (i.e., not publicly accessible) mental phenomena (i.e., memories) from which M-BM data are derived cannot be independently observed, quantified, nor falsified; as such, these data are pseudoscientific and inadmissible in scientific research. Fourth, the failure to objectively measure physical activity in analyses renders inferences regarding diet-health relationships equivocal. Given the overwhelming evidence in support of our position, we conclude that M-BM data cannot be used to inform national dietary guidelines and the continued funding of M-BM constitutes an unscientific and significant misuse of research resources.

“…Previous literature has established a positive relationship between body weight and energy expenditure. 48, 49 That is, the energy expenditure and therefore physical effort during any given weight-bearing activity is far greater in an individual with a high body weight compared to a lighter individual. This may result in increased difficulty during energy-demanding tasks (i.e.…”

This form of exercise is far more energy-costly for overweight and obese women compared to non-weight bearing exercise.…”

Objective This purpose of this review was to examine the relationship between exercise dose and reductions in weight gain during pregnancy in exercise interventions. Design and Methods Four electronic research databases (PubMed, Web of Science, CINAHL, and Academic Search Premiere) were used to identify exercise interventions conducted with pregnant women. Eligible articles must have satisfied the following criteria: inclusion of a control condition, exercise as a major intervention component, weight gain measured and reported for each experimental condition, description of exercise dose (frequency, intensity and duration), and utilized an adequate number of control conditions to assess independent effects of exercise on weight gain. Results The literature search identified 4837 articles, of these, 174 abstracts were screened and 21 intervention studies (18 exercise-only, 3 exercise/diet) were eligible for review. Only 38% of the interventions achieved statistically significant reductions in weight gain during pregnancy. Successful interventions possessed higher adherence and lower attrition rates and were predominantly conducted among normal weight populations. No clear patterns or consistencies of exercise dose and weight gain were evident. Conclusions Adherence and retention rates were strong contributors to the success of exercise interventions on weight gain during pregnancy. However, an exercise dose associated with reductions in weight gain was unquantifiable among these interventions. It is strongly suggested that future researchers investigate methods to increase adherence and compliance, especially among overweight and obese women, and utilize objective measurement tools to accurately evaluate exercise dose performed by the participants and the impact on both body composition and weight gain.

The purpose of this study was to examine the validity of the 1971-2010 United States Department of Agriculture's (USDA's) loss-adjusted food availability (LAFA) per capita caloric consumption estimates. Estimated total daily energy expenditure (TEE) was calculated for nationally representative samples of US adults, 20-74 years, using the Institute of Medicine's predictive equations with “low-active” (TEE L-ACT) and “sedentary” (TEE SED) physical activity values. TEE estimates were subtracted from LAFA estimates to create disparity values (kcal/d). A validated mathematical model was applied to calculate expected weight change in reference individuals resulting from the disparity. From 1971-2010, the disparity between LAFA and TEE L-ACT varied by 394 kcal/d—(P < 0.001), from −205 kcal/d (95% CI: −214, −196) to +189 kcal/d (95% CI: 168, 209). The disparity between LAFA and TEE SED varied by 412 kcal/d (P < 0.001), from −84 kcal/d (95% CI: −93, −76) to +328 kcal/d (95% CI: 309, 348). Our model suggests that if LAFA estimates were actually consumed, reference individuals would have lost ∼1-4 kg/y from 1971-1980 (an accumulated loss of ∼ 12 to ∼36kg), and gained ∼ 3-7 kg/y from 1988-2010 (an accumulated gain of ∼42 to ∼98 kg). These estimates differed from the actual measured increments of 10 kg and 9 kg in reference men and women, respectively, over the 39-year period. The USDA LAFA data provided inconsistent, divergent estimates of per capita caloric consumption over its 39-year history. The large, variable misestimation suggests that the USDA LAFA per capita caloric intake estimates lack validity and should not be used to inform public policy.
