Stimulation of cpt-1 as a means to reduce weight

Abstract

This invention provides methods and compositions for inducing weight loss and maintaining optimum weight comprising administering an agent that stimulates carnitine palmitoyl transferase-1 (CPT-1) activity to the patient in need, including human patients. These methods do not require inhibition of fatty acid synthesis. In particular, this invention provides methods for development of therapeutics that selectively enhance fatty acid oxidation, increase energy production, and reduce adiposity while preserving lean mass, through the pharmacological stimulation of CPT-1 activity. In a preferred mode, the agent is administered in an amount sufficient to increase fatty acid oxidation. In another preferred mode, the agent is administered in an amount sufficient to antagonize malonyl CoA inhibition of CPT-1. In yet another preferred mode, the agent is administered in an amount sufficient to increase malonyl CoA level.

1 . Method of inducing weight loss comprising administering an agent that stimulates carnitine palmitoyl transferase-1 (CPT-1) activity.  
     
     
         2 . Method for stabilizing weight comprising chronic administration of an agent that stimulates CPT-1 activity in an amount that does not significantly inhibit FAS.  
     
     
         3 . Method of screening for agents that induce weight loss, comprising determining whether a candidate weight loss agent stimulates CPT-1 activity, and selecting an agent that stimulates CPT-1 activity.  
     
     
         4 . A therapeutic composition comprising an agent that stimulates CPT-1 activity and L-carnitine.  
     
     
         5 . A nutritional composition comprising nutritionally sufficient amounts of fats, carbohydrates and amino acids, said composition further comprising L-carnitine and an antagonist of malonyl CoA inhibition of CPT-1.
