I've found it quite difficult to get a sense of what a skillful (and practical) spiritual diet would be for a layperson.
Diet seems to be a much simpler topic for monastics because firstly they rely on alms, but secondly Buddha's advice in regards to diet simplifies things (have one meal per day, or some split their one meal into 2 portions, both to be consumed before noon).
However, for a lay follower living in a Western country with a plethora of supermarkets, fast food, sweets, desserts, and other unwholesome foods, it is challenging for me to construct a diet that is both practical and would be considered "skillful means of providing nutriment to the body". I would like to assume it's "not a big deal" and just eat whatever I want to eat (vegetarian of course). However because sense desire and attachment is such a strong theme in the Buddha's teachings, I have found this topic coming to my mind frequently.
I am naturally inclined towards a strong love of food and sensual pleasures. I grew up in an Epicurean household, with an emphasis on fine dining, sampling the foodstuffs of the world, fine wines, and decadent desserts. I know my mind's tendency towards this issue, so I have much time in contemplation about this topic in attempts to find the right balance. I realize that love of food, besides being a hindrance in itself, and one of the fetters, also is an attachment to the form skandha, and additionally indicates an attachment to the taste sense door!! Wow.
I believe that most Buddhists would agree, we are strongly warned to use mindfulness as a gatekeeper to guard the doors to the senses.
Therefore, with this background in mind, I have a number of potential questions it would be wonderful to gain perspective on...
1) Supposing one is over weight, would this necessarily be symbolic of lack of control over sense desire? Or could one be spiritually advanced and still eat too much?
2) Any thoughts on the "Middle Way" between asceticism and overindulgence for lay practioners living in the Western World?
3) While celibacy is difficult for some, at least it's an "all or none" venture... Personally, I have found my relationship with food to be much more complex than my relationship with sexuality. We cannot just swear off food. Therefore, is it ideal to simply eat foods that are not pleasurable yet would constitute nutritional sustenance?
4) Does anyone have any examples of a diet that has worked for them, they might recommend?
5) Is it optimal for spiritual practice, to avoid attachment and distraction, to attempt one meal per day? Personally, I have found it somewhat difficult to find nutritional balance with just one meal per day (I either missing whole food groups, or don't feel I am eating in a well rounded manner for a vegetarian).
6) Is it best to stick to the same meals every day so as to avoid the tendency to crave, cling or grasp for the novelty of new and pleasurable food items?
If you wish, please feel free to provide responses not covered within the scope of these questions. I would strongly appreciate getting some discussion about these topics. Thanks in advance for any insight.

Much Metta.
