Water...drink as much as you like. Make it your primary beverage. It's filling, refreshing and has zero calories. I still enjoy other beverages, have coffee every morning and iced tea (with sugar) throughout the day when I need a change. I even enjoy an occasional soda (again, with sugar). Artificial sweeteners are not healthy; in fact, recent studies have shown they are downright dangerous to your health.
Walking...try to walk everywhere you possibly can instead of driving or taking public transportation. If possible, walk to and from work, or at least one way, to or from. I walk somewhere once a day, nearly every day. It's the only form of "exercise" I engage in, other than housework, yard work and sex.
Waste...the best way not to waste food is not to "clean your plate", but to put less on it to start. I eat whatever I desire, just smaller portions. My great-grandmother lived to be 93, was never ill, never hospitalized, never even had a headache. Her motto: "Everything in moderation." I make sure to eat a balance of fruits, vegetables, grains, etc., but I also enjoy dessert. Often times fruit is dessert. Use your imagination and moderation and that ten pounds will be gone in no time!
I personally haven't tried it, but I went to 1%
Good luck. I still need to loose 8 lbs. but now I have sprained my ankle. so it makes it hard, because I need to walk
The easiest diet is going to be one which includes foods which you enjoy, as that will be easier for you to adhere to.
So you're going to need to find foods you enjoy which are also cheap.
One thing I'll tell you, dieting down is easier when you stick to foods like vegetables, lean meats and fruits as they tend to be low in calories and quite filling for their calorie content.
If you go with too many processed foods, you will have a tougher time as most are quite calorie dense and not filling...although there are exceptions.
One exception I'd say is soup. Soup can be quite filling and a can of it can be 220 - 300 calories. It can be pretty cheap too.
Salads are also a good idea, buy your own lettuce, tomatoes, carrots and onions and you can make your own salads which will be pretty cheap...
Other cheap sources of food for your diet would be cans of tuna for protein, as well as eggs.
Apples for snacks (they're quite filling) and relatively cheap...
And oatmeal/brown/rice/beans for your carb sources, these relatively cheap as well.
Put those together...a good ratio is 40% protein, 30% carbs, 30% fat if you workout...if not, you could go 33%, 33%, 33%....but bottom line:
Eat no less than 1,200 calories/day as a woman and 1,500/day as a man.
