The findings of this one suggest indicate no individual or additive benefit of higher dietary quality on working memory during a 2-year calorie restriction period in healthy adults without obesity and a mean age of 38.1 years.
- The study tried to evaluate the association between dietary quality and spatial working memory in healthy adults without obesity (aged 21–50 y) during a 2-year calorie restriction intervention.
- Two dietary pattern indices with different underlying principles were used: 1) the Dietary Inflammatory Index (DII), which is a validated tool designed to assess the inflammatory potential of individual diets...
...and 2) the Healthy Eating Index (HEI) as an index of dietary quality that is highly correlated with the DII.
- Analysis found no statistical association between the 2 established dietary indices and spatial working memory, a key measure of cognitive function that declines with age.
- In addition, there was no evidence of an effect of caloric resitriction on spatial working memory compared to the Control group.
- "Consuming a healthful diet, particularly a low-inflammatory diet, and practicing CR have been posited to improve cognitive function...
"...However, our findings did not indicate an association between dietary patterns and cognition assessed during the 2-y CALERIE trial of human CR in individuals without obesity."

In this one, an 8-hour time-restricted eating (TRE) protocol was not associated with additional benefits for reducing intrahepatic triglyceride content, body fat and metabolic risk factors compared with daily calorie restriction in adults with obesity and NAFLD.
- All participants were instructed to follow a diet of 1500 to 1800 kcal/d for men and 1200 to 1500 kcal/d for women.
- The diets were composed of 40% to 55% carbohydrate, 15% to 20% protein, and 20% to 30% fat.

In this one, low-load (30–40% 1RM) ballistic exercise was found to be more effective in inducing a delayed neuromuscular potentiation effect and improve ballistic performance after 24 hours compared with high-load (≥85% 1RM) traditional resistance exercise.
- Ballistic exercise was associated with improved CMJ performance after 24 hours.
- Interestingly, the high-load traditional resisistance exercise protocol was not effective in improving neuromuscular performance after 24 hours.

The findings of this one suggest that persistent de novo lipogenesis during fasting may at least partly explain impaired fasting ketogenesis in metabolic syndrome, which appears to be the consequence of reciprocal regulation of DNL and β-oxidation.
- Forty non-diabetic individuals with and without a history of NAFL were recruited for this study.
- Lipogenesis remained detectable in a subset of individuals after a 24 hour fast, including some subjects without hepatic steatosis or other hallmarks of metabolic syndrome.

This one suggests that a supinated grip during the biceps curl may be superior in eliciting the greatest excitation for both biceps brachii and brachioradialis during the concentric phase of the lift.
- This study analyzed the level of excitation of the biceps brachii and brachioradialis during the ascending and descending phase of the biceps curl performed with three different handgrips (supinated, pronated, and neutral).
- Both biceps brachii and brachioradialis exhibited greater levels of excitation with the supinated compared to the pronated and neutral handgrip.

This narrative review tries to determine the potential impact of dietary Arginine and citrulline supplements, including citrulline malate, on cardiovascular health and exercise performance.
- "Taken together, the results of studies conducted on both recreational athletes and trained athletes show that supplementing with 0.075 g or 6 g of Arg per kg body weight did not enhance physical performance and perceptual feeling of exercise or increase NO synthesis...
"...In addition, consuming 2.4 to 6 g of Cit per day for 7 to 16 days of various NSs increased NO synthesis, improved athletic performance, and reduced feelings of exertion...

This one in twins finds that active individuals are more likely to have an intramyocellular lipid phenotype resembling that of athletes.
- Findings also suggested that efficient BCAA catabolism together with BCAA availability are crucial for this intramyocellular lipid phenotype to occur.
To put this into perspective, metabolic syndrome is more than often accompanied by impaired BCAA catabolism.
