Are there any good ways to prevent myself from eating after 7pm?

Healthy eating: Thank you for your question on principles of healthy eating. Consider the following: [1] Main meal of the day between 10AM and 2PM; avoid late night eating. [2] Include all six tastes: sweet, sour, salty, pungent, bitter and astringent in each meal. This discourages binges. [3] Eat according to your body type, age and activity level. * Express gratitude for all who made your meal possible.
