Unfortunately, most biochemistry texts focus on basal metabolism, and there's no shortage of ungrounded dreamers and shills on the popular side. For practical grounding and currently applicable diet/pharmacological interventions I'd strongly suggest a tour of some of the important recent academic reviews in biological gerontology.
López-Otín, Carlos, et al. "
The hallmarks of aging."
Cell 153.6 (2013): 1194-1217.
Gems, David, and Linda Partridge. "
Genetics of longevity in model organisms: debates and paradigm shifts."
Annual review of physiology 75 (2013): 621-644.
Houtkooper, Riekelt H., Robert W. Williams, and Johan Auwerx. "
Metabolic networks of longevity."
Cell 142.1 (2010): 9-14.
Narasimhan, Sri Devi, Kelvin Yen, and Heidi A. Tissenbaum. "
Converging pathways in lifespan regulation."
Current Biology 19.15 (2009): R657-R666.
Rahman, Irfan, and Debasis Bagchi, eds.
Inflammation, Advancing Age and Nutrition: Research and Clinical Interventions. Academic Press, 2013.
Schneider, Edward, ed.
Handbook of the Biology of Aging (bittorrent link). Elsevier, 2012.
While none of these offer practical regimens, they do offer some background in the field, a wealth of keywords for further research, and an intuition of why some current clinical interventions (like HGH) are likely deletorious for lifespan. You may notice that there are just a few poles around which current gerontology is focusing upon with practical anti-aging implications, and among these calorie restriction mimetics and inflammation inhibition are paramount.
