The Claim
In healthy middle-aged adults, sustained 14% caloric restriction over 2 years is associated with increased thymic volume and higher levels of signal-joint T cell receptor excision circles (sjTRECs) in both CD4+ and CD8+ T cells, which indicates enhanced thymopoiesis and improved production of new T cells, suggesting that moderate long-term caloric restriction may counteract age-related thymic involution, a key component of immune aging.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating 14% less food for two years might help middle-aged adults grow a stronger immune system by boosting the thymus, the organ that makes new immune cells — kind of like giving your body's defense system a tune-up as you age.

What the research says
1 studyStudy: Caloric restriction in humans reveals immunometabolic regulators of health span
The study found that eating 14% less food for 2 years helped middle-aged adults maintain a healthier thymus, which makes new immune cells, just like the claim says.
