In 2013, Manfred Lamprecht and team from Graz, Austria, studied 34 obese women in a 12-week trial. They split them into four groups: one got a fruit/vegetable juice powder concentrate, another got the powder plus exercise, a third just exercised, and the last got a placebo. They measured inflammation, oxidative stress, and blood flow markers.

In various studies from 2013 to 2023, researchers like those from the University of Manchester and NBER analyzed data from thousands of retirees in cohort and longitudinal setups. They tracked health changes post-retirement, focusing on cognitive, physical, and mental aspects, adjusting for age, job type, and voluntary status.

A 2024 study by Mass General Brigham found that exercise doesn’t just help memory—it actually activates specific genes that protect against Alzheimer’s. Mice with Alzheimer’s who used running wheels showed better memory, and scientists found that their brains had boosted activity in cells tied to blood vessels and immune defense.

In 2025, Cannavaro, Leva, Caturano, Berra, Bonfrate & Conte (Université Clermont Auvergne & CNRS) reviewed research on using amino acid supplements during weight loss. Their Nutrients paper finds that certain amino acids—especially leucine, HMB, and collagen peptides—help protect lean mass when you’re slimming down.

A 2025 meta-analysis by Kazeminasab et al. (Université Clermont Auvergne & CNRS) reviewed 35 randomized controlled trials with 1,266 adults. They found that combining intermittent fasting with exercise didn’t reduce VO₂max or leg/bench strength, but did slightly boost handgrip strength.

A 2023 summary from Georgia State University and the Society of Behavioral Medicine shows that micro-workouts—short bursts of physical activity lasting from 30 seconds to 10 minutes—can have major benefits for heart health, blood sugar control, mental well-being, and overall endurance.
