It seems simple, and it really is. Eat lots of fruit and vegetables. That's it. However much fruit and how many veggies you currently eat, if you are trying to lose weight, eat more of them.
Some of you may argue that some fruits are very high in certain sugars, and you are right, they are. If you're worried about that, then mostly increase the veggies.
Since I'm advocating relatively low-carb eating it may seem contradictory for me to tell you to eat more of these two groups. But the principle is to get most of your carbs this way. Fruit and vegetables have a lot of fiber and vitamins that you need, so I don't think they should be cut out. So leave them in, and cut the carbs that don't have as much good stuff in them.
Increasing fruit and veggies will help you to feel more filled and satisfied from your meals. And a lot of them are just plain delicious. I pity those of you who don't live in Papua New Guinea like I do, where you can have access to the best bananas and pineapples that we do. But in North America you have better access to apples, pears, peaches, plums and grapes than we do. I'm currently in the US, and I'm trying to enjoy these as much as I can while I'm here.
I know that there are lots of people who don't care for veggies. If there are a few that are not too replusive for you, concentrate on those. For the others, experiment with new ways to prepare them. We have recently started roasting a lot of ours vegetables. Just lay them in a baking dish, slightly separated, and put them in a medium oven for about 10 minutes. This really brings out different flavors than other cooking methods, and it's quick and easy.
Also, there are probably veggies that you have never tried. Experiment a little. You never know what great new favorites you'll discover!
See you on the road!
