1. A dry weight loss composition suitable for ingestion by an obese subject, said composition comprising a particle admixture of: at least one exogenous amino acid precursor able to be utilized in a catecholamine biosynthesis pathway, in a quantity within the range of 0.01 g to 1.0 g; at least one exogenous sympathomimetic agent able to stimulate the sympathetic nervous system, in a quantity within the range of 0.2 g to 1.0 g; a lipolytic agent able to increase and substantially augment the rate of fatty acid oxidation then existing in the obese subject, in a quantity within the range of 0.05 g to 1.0 g; and a high-Dalton macromolecular protein selected from the group consisting of proteins generated by enzyme reaction or acid digestion and having an atomic weight of not less than 1400 Daltons, said high-Dalton macromolecular protein enables the obese subject to avoid depleting skeletal muscles for their available protein stores in-vivo, in a quantity within the range of 1.0 g to 12.5 g.
