3 New Papers: Keto's Hidden LPS Spike, Exercise Overhauls Cholesterol in Older Women, and a 47-Minute Sleep Fix for Teens

Three PubMed papers indexed May 28–June 4, 2026: a 12-week RCT (n=90) finds keto + caloric restriction cuts body fat 21.7% and insulin resistance in prediabetes, but significantly raises LPS (a gut-derived inflammatory marker); a 23-RCT meta-analysis shows supervised exercise cuts total cholesterol 26.7 mg/dL and systolic BP 8.35 mmHg in older women; and a 2-week RCT in 86 adolescents finds a personalized sleep schedule + morning bright light + amber glasses gains 47 minutes of weeknight sleep and shifts circadian timing 45 minutes earlier.

3 New Papers: Lose Visceral Fat Once and It Pays Off for a Decade, Resistance Training's Mortality Sweet Spot, and Exercise as Sleep Medicine

Three PubMed papers indexed May 27–June 3, 2026: a 10-year MRI follow-up of two RCTs (n=366) shows visceral fat loss durably cuts T2D risk by ~30% even after full weight regain; a 147,374-person 30-year cohort study finds 90–119 min/week of resistance training cuts all-cause mortality 13% and CVD mortality 19%, with no extra benefit above 120 min/week; and a 32-person 16-week RCT shows multimodal exercise cuts waking-after-sleep-onset by 33 minutes in older adults, measured by actigraphy.

3 New Papers: EAT-Lancet Diet Cuts Heart Risk but Has Nutrient Gaps, VR Beats Fear of Falling, Acupuncture Matches CBT for Perimenopause Insomnia

Three PubMed papers indexed May 27–June 1, 2026: a 227-study meta-analysis (>1M participants) finds the EAT-Lancet planetary diet cuts all-cause mortality by 20% and CVD risk by 17%, but predicts B12/calcium/iron/zinc deficits globally; a 34-person RCT finds VR balance training significantly reduces fear of falling in older adults vs conventional training, with higher motivation; and a 160-woman non-inferiority RCT shows electroacupuncture matches CBT-I for perimenopausal insomnia within a pre-specified margin.

3 New Papers: Anti-Inflammatory Diets for Joints, Fisetin Boosts Exercise Recovery, Acupressure + CPAP Clears Both Sleep Disorders at Once

Three PubMed papers indexed May 25–31, 2026: a 40-person RA RCT finds both Mediterranean and standard healthy eating improve dietary inflammatory index within 12 weeks but don't shift patient symptoms; a 44-man obesity RCT shows concurrent interval resistance+aerobic training raises the inflammation-resolving lipid Maresin-1, amplified by 200 mg/day fisetin; and a 114-patient three-arm RCT finds chronotherapy-timed auricular acupressure added to CPAP significantly reduces insomnia severity beyond CPAP alone.

3 New Papers: Plant Protein Pairing Busts a Myth, Digital Steps for Older Adults, Sleep Drug Spray Beats Pain-Driven Insomnia

Three PubMed papers indexed this week: a crossover RCT (n=11) finds 20 g protein from beans + rice drives the same post-exercise muscle protein synthesis as isolated amino acids; a 26-RCT meta-analysis (n=4,129) shows multicomponent digital health tools add +823 steps/day and +46 min MVPA/week in older adults; and a 70-person RCT finds dexmedetomidine nasal spray over 3 nights significantly improves deep sleep and reduces nighttime awakenings in pain-related insomnia.

3 New Papers: Wild Blueberries Blunt Glucose Spikes, Graded Exercise Reverses Frailty, Treating Sleep Apnea Smooths Overnight Blood Sugar

Three PubMed papers indexed this week: a 24-person crossover RCT shows wild blueberry anthocyanins (≥300 mg) reduce post-breakfast glucose and boost satiety hormones in a dose-dependent manner; a 111-person multi-center RCT finds a TUG-calibrated exercise program reversed frailty in 21% of older adults after 5 months; and a 14-study meta-analysis confirms CPAP treatment for sleep apnea significantly reduces nocturnal glucose variability in people with type 2 diabetes.

3 New Papers: Flexitarian Diet Rewires Gut Tryptophan, Exercise + Cognition After Stroke, tVNS for Insomnia

Three PubMed papers indexed this week: a flexitarian crossover RCT (n=19) shows swapping to legume-heavy protein shifts gut bacteria and tryptophan pathways in men at cardiometabolic risk; a 44-RCT meta-analysis (n=4,450) finds aerobic + cognitive-motor dual-task exercise produces the largest cognitive gains after stroke; and a 13-RCT tVNS meta-analysis finds ear-clip vagus nerve stimulation consistently improves sleep quality and insomnia severity, especially targeting the ear's concha region.

3 New Papers: Gut Bugs Predict T2D Decades Out, Isometric Exercise Falls Short for Tendon Pain, Liraglutide Boosts Sleep Quality

Today's three PubMed picks: a 4,685-person prospective cohort finds specific gut bacteria — including Akkermansia muciniphila when dietary fiber is low — predict type 2 diabetes risk over 5 years; a systematic review of 13 RCTs finds isometric exercise offers limited evidence of superiority over eccentric protocols for tendon pain; and a Phase IV liraglutide RCT reports significant improvements in sleep quality alongside metabolic markers — gains that reversed after stopping the drug.

3 New Papers: Low-Cal Diet Reverses T2D, TV Watching Raises COPD Risk, Haptic Device Beats Insomnia in a Week

This morning's three PubMed picks: a 12-week meal-replacement program cut A1C by 1% in T2D patients; a Mendelian randomization study found TV watching causally raises COPD risk while vigorous exercise cuts sleep apnea risk; and an RCT showed a haptic-feedback device brought 37.5% of insomnia sufferers to clinical improvement within one week.
