i miss playing tennis... we live out in the boonies since i moved from germany... now its hickville arkansas... lol... no tennis courts around here... just horses goats and cows...
sounds like a really good plan... although counting calories isnt my strongpoint... i end up feel malnourished... im just trying to make better choices...
I try to pick things to eat during the day that are high in fiber but low in calories, so they're more filling. Then at night, usually my mom and I go out to dinner or I cook, and I can eat almost anything I want (within reason, I'm not saying get like a bucket of fried chicken or a greasy hamburger.. but your basic dinner entree with two sides is fine.. maybe only eat half and take the rest home).
Another thing that helps is just using a smaller plate or bowl. It helps you cut back on portion size but makes you think you're eating more than you are.
Drink a lot of water and cut out sodas entirely, even diet soda isn't good for you. I drink Diet V8 Splash here and there, it tastes great and only has like 10 calories per glass. You don't think about how many calories are in your drinks but there are so many empty calories in sodas. If you don't waste your calories on sugary drinks then you have plenty of room to have a decent meal. If you go to a restaurant and you decide you really want a soda, then go ahead, but don't refill, get water after that, and don't make a habit of it.
Another way to get in some light exercise when you can't get out and walk or something is to turn on some music and do a bunch of housework. It helps to move around a lot while you're doing it, and it's actually sort of fun.
And always remember, if you lose sight of your goal and go overboard one day, don't get depressed over it, just bounce back and keep working at losing that weight. It's not the end of the world, just try not to do it too often.
I guess those are my best tips for losing weight, but so far they seem to be working for me.
Good luck!
