When I am at home alone and will be spending most of my day there, I've established the habit of setting out small portions of colorful and tasty (to me) foods in the morning, that I wish to snack on during the day, so that I don't have to take time throughout the day to prepare food or go too long without eating and then want to binge on something (not that there's anything unhealthy in my home to binge on!).
For me, it's been a terrific way to eat mostly raw, eat portion size, to eat loads of antioxidants, to enjoy a wide variety of foods throughout the day that I might not consume if I were preparing meals separately. By nature i am a grazer and I prefer to eat sufficiently for the activities I am participating in.
For example today, I have 4 dogs in house that I am pet sitting and I have to go out of the house 3 times today to make a dog sitting visit just up the road a bit from me. I will use my bicycle to go on that visit. Since my energy expenditure will not be much, yet I need some fuel in my muscles to bike, I'll eat nutritiously, yet sparingly, like below.
If I feel my blood sugar getting low, I know how to fuel properly. If I feel my concentration and focus waning, I know how to get my essential fats (nuts, seeds).
Foods on Left Tray: Blueberries, walnuts, tomato, home-grown mung bean and lentil sprouts, spinach.
Foods on Right Tray: Red cabbage, celery, yellow bell pepper, watermelon, ruby red grapefruit, cucumber, snow peas.
I will also drink lots of reverse osmosis water and green tea.
I've actually lost 14 lbs of weight in 8 weeks by eating like this, exchanging bicycle riding for car use in my work = 40 - 100 miles per week cycling, and eliminating all refined sugars from my diet. And it feels great!
