The dietary habits of individuals are integral to understanding their nutritional wellbeing, making this assessment crucial for public health interventions. The objective of the study was to assess the dietary intake pattern and nutritional status among women of reproductive age in slum areas of Pokhara Metropolitan. <i>Methodology</i>. A cross-sectional analytical study was conducted to assess the dietary intake pattern and nutritional status among 404 women of reproductive age in the slum area of Pokhara from June 2019 to December 2019. A simple random sampling technique was used to select the wards while a purposive sampling technique was used to collect the samples. 24-hour recall meal-based questions and anthropometric measurements were used for collecting data.

The objective of this study was to evaluate the impact of 12 g of additional protein in the form of a protein supplement compared to a placebo combined with a simple exercise program on plasma amino acid level, body composition, and muscle strength among healthy Indian adults having a relatively sedentary lifestyle. This double-blinded, randomized controlled trial was conducted on sedentary healthy adults 20-45 years of age, with a body mass index (BMI) between 18.5 and 27.9 kg/m². Eighty-two participants were randomized into either the protein (intervention) or placebo (control) group. The exercise regime was the same for both groups.

Blood tests were conducted for the amino acid OMICS measurement followed by dual-energy X-ray absorptiometry (DXA) for body composition and isokinetic dynamometry for muscle strength. A significant improvement was observed in the lean mass (kg) and appendicular muscle mass (AMM) adjusted for weight in the intervention group compared to the control group (<i>p</i> < 0.05).

In a recent study, we observed a drop in testosterone levels following the oral ingestion of racemic sodium-&lt;i&gt;β&lt;/i&gt;-OHB. In this investigation, we aim to determine whether a single oral dose of ketone ester (study I) and prolonged endogenous ketosis (study II) also reduces testosterone levels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Design: &lt;/strong&gt;This investigation integrated samples from two distinct studies. Study I was a randomized, controlled, crossover trial with ten healthy, young male participants receiving either a weight-adjusted ketone ester or control (water, CTR) and vice versa following an overnight fast. Repeated blood sampling was used to monitor plasma &lt;i&gt;β&lt;/i&gt;-OHB and testosterone levels. Study II, another randomized, controlled, crossover trial, included 11 middle-aged participants (five males). They followed either a ketogenic diet (KD) characterized by low carbohydrates and high fat content or a standard diet (SDD) for three weeks. After each study period, participants underwent examination following an overnight fast, with repeated measures employed to analyze concentrations of plasma &lt;i&gt;β&lt;/i&gt;-OHB and sex hormone levels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Study I: Testosterone decreased from 23.8 ± 2.4 nmol/l to 22.3 ± 2.5 nmol/l 300 minutes after the ketone ester and increased from 20.9 ± 2.1 nmol/l to 22.2 ± 1.9 300 minutes after CTR. This difference was not significant, &lt;i&gt;p&lt;/i&gt; = 0.06. &lt;i&gt;Study II&lt;/i&gt;. Total testosterone was unaffected after the KD compared to the SDD in men (20.2 ± 1.23 nmol/l vs. 18.2 ± 1.23 nmol/l (&lt;i&gt;p&lt;/i&gt; = 0.1)) and was lower after KD in women (0.87 ± 0.06 vs. 1.1 ± 0.06 nmol/l (&lt;i&gt;p&lt;/i&gt; &lt; 0.0001)). Sex hormone-binding globulin (SHBG) increased in men after KD compared with SDD (31.2 ± 2.6 nmol/l vs 25.0 ± 2.6 nmol/l, &lt;i&gt;p&lt;/i&gt; &lt; 0.0001) and women (26.5 ± 3.05 nmol/l vs 24.2 ± 3.05 nmol/l, &lt;i&gt;p&lt;/i&gt; = 0.003). The free androgen index decreased after KD in men (ratio: 0.65 ± 0.05 vs. ratio: 0.74 ± 0.05, &lt;i&gt;p&lt;/i&gt; = 0.04) and in women (ratio: 0.036 ± 0.006 vs. SDD 0.05 ± 0.006, &lt;i&gt;p&lt;/i&gt; = 0.0001). Free estradiol index was also found lower after KD in men (ratio: 3.1 ± 0.8 vs. ratio: 4.8 ± 0.8, &lt;i&gt;p&lt;/i&gt; = 0.0003) and in women (ratio: 1.2 ± 2.2 vs. 9.8 ± 2.2, &lt;i&gt;p&lt;/i&gt; = 0.0001).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Our findings indicate that the acute ingestion of ketone ester may not reduce testosterone levels in healthy young males. However, a three-week exposure to KB from a KD results in an increase in SHBG in men and women with obesity as well as it lowers free testosterone and estradiol for men and women. We thus present evidence of crosstalk between alterations in a metabolite, &lt;i&gt;β&lt;/i&gt;-OHB, and the regulation of the hypothalamic-pituitary-gonadal axis from a KD.
