mastication and BMI, drinking water and BMI

[Liz Hill]

Hello:
 
Please pardon the cross-posting.  
 
Is anyone aware of research to support that people who eat slowly, or chew
their food carefully actually have a lower body weights?  
 
Instructing clients/patients to chew their food deliberately, set down the
fork between bites, etc. is a common tip used by many nutritionists, but do
we have any evidence to support that engaging in these behaviors will aid
weight loss, or that people who naturally have these eating behaviors have
lower BMI's?  I have searched the literature, but have not found anything to
support or discredit it.
 
The other 'tip' I'm interested in is telling clients/patients to drink water
to "help them feel fuller".  I am aware of the literature relating to the
energy density of foods and satiety, but can anyone point me to research
indicating that drinking liquid water will either increase satiety or
decrease caloric consumption in subsequent meals?  I am aware of research
indicating it DOES NOT, but any suggestions of supporting studies would be
appreciated.
 
Thanks for your help.  I'm happy to compile and share the comments I
receive.
