A light diet means eating simple small meals that are easily digested. I see that you are very good with your food and to ensure your food passes quickly through your system just follow the Food Combination guidelines.
THE HAY RULES FOR HEALTH
Starches and sugars should not be eaten with proteins and acid fruits at the same meal.
Vegetables, salads and fruits (whether acid or sweet) if correctly combined should form the major part of the diet.
Proteins, starches and fats should be eaten in small quantities.
Only whole grains and unprocessed starches should be used and all refined and processed foods should be eliminated from the diet.
Not less than four hours between starch and protein meals.
Milk does not combine well with food and should be kept to a minimum.
Don't mix foods that fight, see below chart.
Mix anything from List A with List B
Mix anything from List C with List B
Never mix List A and C!
Mix vegetables or salads with pulses i.e. beans/lentils - make these and unprocessed foods the main part of your diet.
Don't get too fussy about these guidelines they are a tool in the toolbox that might be useful to you. Adapt them to suit yourself.
I only drank Celery Seed Tea for about a month before starting the Liver Cleanses because I felt my water works were just fine. So I agree with you that you've done enough.
I eat what I think is right, I'm happy with that, I good quality and varied and like you I enjoy a few treats; 90% is good.
