Capsaicinoids, the pungent principles of chili peppers and prototypical activators of the transient receptor potential of the vanilloid type-1 (TRPV1) channel, which is a member of the expanded endocannabinoid system known as the endocannabinoidome (eCBome), counteract food intake and obesity. In this exploratory study, we examined the blood and stools from a subset of the participants in a cohort of reproductive-aged women with overweight/obesity who underwent a 12-week caloric restriction of 500 kcal/day with the administration of capsaicinoids (two capsules containing 100 mg of a capsicum annuum extract (CAE) each for a daily dose of 4 mg of capsaicinoids) or a placebo. Samples were collected immediately before and after the intervention, and plasma eCBome mediator levels (from 23 participants in total, 13 placebo and 10 CAE) and fecal microbiota taxa (from 15 participants in total, 9 placebo and 6 CAE) were profiled using LC-MS/MS and 16S metagenomic sequencing, respectively.

This longitudinal study examined the potential relationship between the adiponectin/leptin ratio (A/L, a marker of adiposopathy) and insulin resistance (IR: homeostasis model assessment (HOMA)), insulin sensitivity (IS: Matsuda), and insulin response to an oral glucose tolerance test before and after a 16-week walking program, in 29 physically inactive pre- and postmenopausal women with obesity (BMI, 29-35 kg/m; age, 47-54 years). Anthropometry, body composition, VOmax, and fasting lipid-lipoprotein and inflammatory profiles were assessed.

Methods: Sixteen late premenopausal (mean [SD] age, 49 [3] y; mean [SD] body mass index, 31.9 [3.
Objective: The aim of this study was to examine regional variation in adipose tissue lipoprotein lipase (AT-LPL) activity and expression in pre-and postmenopausal women, before and after training, once differences in chronological age or obesity degree are taken into account.
Methods: Sixteen late pre- and 14 early postmenopausal (49 +/- 2 vs. 52 +/- 2 years; p < 0.
Objective: Aerobic exercise is known to improve health-related quality of life (QoL). The aim of this study was to compare the effects of a 16-week walking program on eating behaviors and QoL between late premenopausal and early postmenopausal obese and sedentary women, once chronological aging is taken into account.
Methods: Sixteen women 49 +/- 2 years old and 14 women 53 +/- 2 years old, whose body mass index ranged between 29 and 35 kg/m, were subjected to three sessions per week of 45-minute walking at 60% of their heart rate reserve.
