3 New Papers: One 16-Hour Fast Won't Boost Muscle Gains, Morning Lifting Has a Calorie Illusion, and an App Can Replace Your Sleep Clinic

Three PubMed papers indexed June 2–9, 2026: a crossover study (n=9) finds a single 16-hour fast does not enhance muscle protein synthesis vs. a 10-hour fast; a crossover trial (n=13) shows morning resistance training's apparent calorie-burn advantage disappears once circadian-rhythm fluctuations are accounted for; and a 15-RCT meta-analysis (N=3,507) finds fully automated digital CBT-I apps produce a large, consistent reduction in insomnia severity (SMD −0.82) comparable to in-person therapy.

3 New Papers: A 5-Day Fasting Protocol Resets Your Gut, Aerobic Exercise Trims Postmenopausal Body Fat, and CBT-I Calms Dementia Behaviors

Three PubMed papers indexed June 1–7, 2026: an n=64 RCT finds a 5-day ~600 kcal/day fast cuts inflammation and shifts gut bacteria (but effects reverse within a month, and industry COI applies); a 16-RCT meta-analysis (n=1,571 postmenopausal women) confirms aerobic training cuts body fat −1.40% and waist −2.02 cm; and a 240-person cluster RCT of CBT-I in nursing homes finds sleep scores don't improve dramatically but agitation, depression, and other dementia behaviors do.

3 New Papers: Sweeteners Edge Out Sugar for Weight Maintenance, Exercise Resolves Inflammation, and Resistance Training Halves Sleep Apnea Severity

Three PubMed papers indexed June 1–7, 2026: an 83-person 12-month RCT finds sweeteners may slow weight regain after dieting (3.0 vs. 5.9 kg, p=0.050), but multiple authors have industry funding ties; a 4-arm 12-week RCT (n=44 obese men) shows interval resistance-aerobic training raises the inflammation-resolving mediator Maresin-1 and cuts HOMA-IR, with fisetin adding to the anti-inflammatory effect; and an 8-week RCT (n=25) finds resistance training alone reduces apnea-hypopnea index by ~21 events/hour in moderate-to-severe OSA, confirmed by polysomnography.

3 New Papers: Low-Carb Depletes B Vitamins, Resistance Training Clears T2D Risk Markers, and an App-Based Therapy Quiets Insomnia

Three PubMed papers indexed May 30–June 6, 2026: a 193-person 12-month RCT finds ketogenic diets significantly lower nicotinamide and B6 metabolites independent of dietary B-vitamin intake; a 33-RCT meta-analysis (n=1,396) shows resistance training cuts HbA1c 0.62%, HOMA-IR 0.90, and SBP 3.91 mmHg in adults with T2D; and an 8-RCT meta-analysis finds internet-based acceptance and commitment therapy cuts sleep quality scores (SMD −0.92) and insomnia symptoms (SMD −0.40) versus passive control.

3 New Papers: Spread Your Protein Across Meals, HIIT Intensity Matters for Visceral Fat, and Brain Stimulation Beats Insomnia

Three PubMed papers indexed May 29–June 5, 2026: a 16-week RCT (n=44 women) finds even protein distribution across meals cuts snack food cravings and intake vs. dinner-heavy protein; an 8-week RCT (n=40 sedentary men) shows high-intensity interval training beats moderate intensity for visceral fat and LDL; and a 19-RCT meta-analysis (n=1,690) confirms low-frequency rTMS significantly improves sleep quality, including PSG-measured sleep efficiency.

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.
