Energy balance
Very-low-carbohydrate diets enhance human T-cell immunity by inducing ketone body production (specifically beta-hydroxybutyrate), which reprograms T-cells to favor oxidative metabolism, improves cellular energy supply, and increases T memory cell formation.
If you reduce carbohydrate intake significantly, your body produces ketones like beta-hydroxybutyrate. This shift can reprogram your T-cells to use energy more efficiently via oxidative metabolism, potentially enhancing their ability to form long-term memory and respond to pathogens.

Interestingly, in human volunteers on a very-low-carbohydrate diet CD4+, CD8+ and regulatory T-cell capacity was markedly enhanced and T memory cell formation was increased. Molecular analysis of these cell subsets revealed an immunometabolic reprogramming in response to ketones favoring oxidative metabolism and conferring superior cellular energy supply and reactive oxygen species (ROS) signaling (44).
Why this rating
Cites a specific human volunteer study (Ref 44) showing enhanced T-cell capacity.

- High intake of dietary fructose (common in Western diets) metabolically rewires innate immunity by increasing mTORC1 activity and IL1B expression in monocytes/macrophages, thereby promoting a pro-inflammatory state and reducing metabolic flexibility.Good
- Omega-3 polyunsaturated fatty acids (PUFAs) and other unsaturated fats inhibit Toll-like receptor 4 (TLR4) activation and pro-inflammatory cytokine release, thereby ameliorating chronic inflammation driven by saturated fats and LPS.Good
- Obesity and the associated accumulation of bone marrow adipocytes disrupt normal hematopoiesis and immune function by creating a pro-inflammatory environment mediated by TLR4 activation, leading to impaired immune responses and increased morbidity/mortality during infections.Good
