This study set out to compare how different types of exercise affect muscle metabolism and insulin sensitivity in the short term. Twelve healthy young men did three sessions: sprint intervals…
This study looked at whether vitamin D changes how well metformin (a common diabetes drug that lowers blood sugar) can bring down prolactin (a pituitary hormone that suppresses testosterone when…
This study looked at whether a quick, low-effort high-intensity interval training routine (REHIT) could improve blood sugar control after meals and over a full day in healthy, active middle-aged men.…
This study set out to see if moderate-intensity walking could improve glucose tolerance after a night of partial sleep restriction, as high-intensity exercise has been shown to do. Eleven healthy,…
This study set out to see how swapping some animal protein for plant protein affects gut bacteria and tryptophan processing in men at risk for heart and metabolic problems. It…
This study looked at how high-intensity interval training (HIIT), where short bursts of hard effort alternate with easier recovery periods, with or without L-citrulline (an amino acid that may boost…
This study looked at whether adding avocado and mango to the diet improves blood vessel function and metabolic health in adults with prediabetes. It was a randomized trial where 82…
This study compared two exercise approaches, high-intensity functional training (HIFT) and traditional resistance training (RT), for improving metabolic, inflammatory, and physical health in overweight men. Thirty-four men with an average…
This study compared two forms of omega-3 supplements, structured triglycerides (STGs) and physical mixtures (PMs), to see which better boosts blood EPA levels and muscle performance. Twenty-eight healthy young men…
This study tested whether a workplace canteen could improve the health of men with metabolic syndrome (a cluster of a large waist, high blood pressure, high blood sugar, high triglycerides,…
This study set out to see whether ashwagandha, a herb widely sold for stress and performance, adds anything to interval training. Interval training here meant repeated hard efforts on a…
This study set out to see whether restricting the hours of the day a man eats improves how his body handles sugar. Fifteen men at risk of type 2 diabetes,…
This study set out to test whether the benefits of intermittent fasting come only from losing weight. Men with prediabetes ate all their meals inside a 6 hour window early…
This study set out to test whether vitamin D supplements raise testosterone in healthy men. It randomly assigned 98 men with normal testosterone but low vitamin D to a high…
This study looked at whether catching up on sleep at the weekend improves insulin sensitivity and hormones in men who habitually sleep too little in the week. Nineteen such men…
