Doctor: Recent pharmaceutical advances will lead the way in weight loss. Prior to these advancements, obesity-related deaths outnumbered all other causes of death by a wide margin. The new drugs will curb appetite and increase metabolism. Thanks to these advancements, obesity will dramatically decline in the near future. Each of the following, if true, strengthens the doctor's argument EXCEPT: ['Participants in several studies reported significant appetite reductions.', 'Nutritious food is not readily available to many people suffering from obesity.', 'Increasing metabolism would significantly reduce obesity across the country.', 'Most people will not be able to afford these prescriptions since the majority of health care plans will not cover the new drugs.']
