@anonymously99stwin,
Yep, agree - nothing wrong with
dalehileman -- just some good-natured ribbing, in response to some good-natured ribbing . . .
So, we've really expanded (correctly so, I believe) on some of my original speculation, although a couple of offerings are variations on what I initially noted:
• Reduced incomes in later years and consequently less money to buy nutritious food
• Diminished cognitive processes and simply forgetting to eat regularly
• Lack of facilities or the motivation to cook and eat regularly
• Reduced or loss of appetite due to the aging process
• Reduced effectiveness of the digestive system to process food into bodily stores (fat, muscle, etc.)
• Appetite affected by the prescription medication interaction or contraindications
• Physical caloric needs just reduced due to lesser levels of energy expended
• Too much hassle to prepare food (lack of motivation)
• Food may lack flavor and taste (due to preparation methods or sensory threshold diminished), which may reduce appeal and consequently intake
• Prescribed or self-imposed dietary limitations or restrictions
• Changes in emotional state (depression), which translates into reduced appetite or interest in eating
• Less body mass makes mobility issues associated with aging easier to deal with (I'm not sure about this one . . .)
• Reduced cognitive processes (dementia), and forgetting to eat (occasionally or completely)
• Inability to adequately prepare, obtain nutritious ingredients, or simply lack of access to cooking facilities
• Social or other economic sources which reduce means, motivation or opportunity (hey wait, aren't these the elements of criminal investigations?)
I think this summarizes the core theories, along with some of the variations on the core theories. Others?
