For a lot of people it is time consuming and a bit hard to plan a meal that includes veggies, fruits etc. So what i do (and really worked for me!) is to distribute my day in the following way:
1.IM A MONKEY IN THE MORNING!
Morning: Only fruits. I usually like to play with the blender and put all the fruits i can think of, or have available,to make a nice healthy (and very filling!) juice that keeps me going through out the day. Its so easy, all you have to do is identify a fruit and place it inside the blender.
2. Half a vegan Half a Fisherman lunch!
Take a big dish and mentally divide it into two. Place grilled/steam fish (or also chicken...but avoid red meat!) on one side. Fill the other half with veggies...any veggie you can find and think of ( raw fresh veggies are better)- Aim to have that half of the dish as colourful as possible :)!
3. Whatever I want Night!
Ok, is not like 'whatever i want' but is very likely that since you have put effor during the day you wont want to mess it up at night. So usually i have a small bowl with brown rice and tofu or chicken or fish. Sometimes I have tuna salad...whatever thats healthy :)
Hope its helpful, i created this concept after reading a couple of books on how to loose weight...but maybe is somehow not healthy.
Also: throughout the day drink green tea!
