Comparative Study
Prediction and evaluation of resting energy expenditure in a large group of obese outpatients.
The aim of this study was to compare resting energy expenditure (REE) measured (MREE) by indirect calorimetry (IC) and REE predicted (PREE) from established predictive equations in a large sample of obese Caucasian adults. ⋯ Different established equations can be used for estimating REE at the population level in both sexes. However, the accuracy was very low for all predictive equations used, particularly among females and when BMI was high, limiting their use in clinical practice. Our findings suggest that the validation of new predictive equations would improve the accuracy of REE prediction, especially for severely obese subjects (BMI>40 kg m-2).

Observational Study
Diet diversity, growth and adiposity in healthy breastfed infants fed homemade complementary foods.
Infant complementary feeding is important for establishing food preferences. Few studies exist on the effects of infant complementary feeding choices (food preparation methods) on dietary intake, growth or adiposity. We examined whether provision of homemade complementary food is associated with the development of dietary diversity, nutrient intakes and quality of infant growth. ⋯ Provision of homemade complementary food is associated with increased dietary diversity during the first year of life and reduced adiposity.

The association of obesity susceptibility variants with change in body mass index (BMI) across the life course is not well understood. ⋯ The observed association between variants in/near FTO, MC4R, MTCH2, TFAP2B, SEC16B and TMEM18 with change in BMI from adolescence to young adulthood suggest that the genetic effect of BMI loci varies over time in a complex manner, highlighting the importance of investigating loci influencing obesity risk across the life course.
