I you have 3 meals a day, and you eat a strong break fast in the morning, and good launch, you can always go light or don't eat at night. Eating at night is not good at all you are not doing exercise or any activity that will make you burn calories. I'm talking based on my personal experience.
I actually eat 5 meals a day: 3 regular meals and 2 small ones in between. I do a lot of exercise and I can’t go more than 5 hours without eating. Normally I eat something every 3 hours and I must say I am quite lean and healthy. Our body needs to be fed frequently, that is what gets our metabolism going. Low GI foods and fiber content are the keys for our body to actually use the food we are giving it and not storing it as fat. I luckily enjoy all the healthy options.
