It is interesting to note that the KBs are able to produce more energy compared with glucose because of the metabolic effects of ketosis — the high chemical potential of 3 - β - hydroxybutyrate leads to an increase in the ΔG0 of ATP hydrolysis.3 A further point to underline is, as shown in Table 1, that glycaemia, even though reduced, remains within physiological levels because of the fact that glucose is formed from two sources: from glucogenic amino acids and from glycerol liberated via lysis from triglycerides.7
