The prevalence of obesity has increased dramatically in recent years (National Audit Office, 2001). Satiety influences the frequency of meals and snacks, whereas satiation influences the size of meals and snacks. Macronutrients have differing effects on satiety; protein is more satiating than carbohydrates that are more satiating than fat (Hill and Blundell, 1986; Barkeling et al, 1990; Stubbs, 1995). The exact mechanism by which protein exerts its satiating effect is not elucidated, but it may involve changes in the levels and patterns of metabolites and hormones (e.g. amino acids, glucose and insulin), cholecystokinin and amino acid precursors of the neurotransmitters serotonin, noreadenaline and dopamine. A meat-containing meal was shown to have more sustained satiety than a vegetarian meal (Barkeling et al, 1990). Other studies have shown that different meats have different satiating powers (Uhe et al, 1992). These differences may be related to differences in amino acid profiles or digestibilities. More research on the effects that different meats have on satiety will prove invaluable in assessing whether or not meat can, in the future, be promoted as a food that can negatively curb the growing levels of obesity.
