100 Days Into 'One Year Fast,' DEXA Shows Major Body Recomposition Alongside Significant Cardiovascular Change

DEXA measurements show 5.3 lbs of fat loss and a 6.3-lb increase in lean mass at unchanged body weight during a 52-week protocol of fasting three full days per week.

VENICE, Fla., Sept. 28, 2026 /PRNewswire/ -- Marking 100 days into his 52-week personal health study, Alfie Hammersham, founder of the One Year Fast Project, has released his first comprehensive clinical measurements alongside an ongoing public chronicle of fasting three full days each week.

Launched on the 2026 Summer Solstice, the project follows an intensive framework: fasting for three complete days weekly across 52 consecutive weeks. Rather than relying on anecdotal claims, the project documents physiological adaptations in full public view via a live biomarker portal at oneyearfast.com/dashboard and daily video journals on YouTube.

The 100-Day Clinical Biomarkers

Quarterly evaluations—conducted via Dual-Energy X-ray Absorptiometry (DEXA) body composition scanning and metabolic graded exercise testing (VO2 Max)—provide an early snapshot of physical adaptation:

• Substantial Body Recomposition: Despite maintaining an identical scale weight of 180.0 lbs, DEXA scans recorded a 5.3-lb loss in fat mass (body fat dropped from 29.9% to 26.8%) alongside a 6.3-lb increase in lean mass (117.8 lbs to 124.1 lbs). Total lean tissue rose from 66.2% to 69.4% [Video Analysis: DEXA Scan Results].
• Lean Mass on a Plant-Based Fast: Lean mass increased despite fasting three full days weekly on a vegetarian diet. Because DEXA lean mass encompasses organs, fluids, and non-bone tissue alongside muscle, the project specifically reports the metric as lean mass rather than claiming direct muscle gain.
• The Aerobic Reality Check: Cardiorespiratory testing showed VO2 Max declining nearly 16%, from 49.1 to 41.4 mL/kg/min. Hammersham attributes this change primarily to reduced training volume and recovery trade-offs, noting the observations do not establish direct causality [Video Analysis: VO2 Max Testing].

Beyond the Scale: "Fasting Feeds the Soul"

While clinical assays quantify physiological changes, Hammersham views the project as a holistic inquiry. Daily unscripted YouTube dispatches document the psychological, mental, and spiritual realities of sustained abstinence. At day 100, Hammersham identified the project's central realization: "Fasting feeds the soul."

"Beyond the physical recomposition, removing food as an emotional dependence uncovers clarity, humility, and conscience," said Hammersham.

The daily chronicles explore ethics, privilege, and consciousness—including Hammersham sharing his private 1997 correspondence with the office of Diana, Princess of Wales, honoring her humanitarian campaign to eradicate landmines [Video: 1997 Correspondence with the Office of Diana, Princess of Wales], as well as reflections on artificial intelligence and James Lovelock's Novacene [Video: Artificial Intelligence and James Lovelock's Novacene].
