Here's my 2 cents' worth...
The most important set of scales involved in the process of losing weight are those to weigh food BEFORE you eat it, not the scales you stand on afterwards.
As I think Doug has mentioned, it's real easy to "estimate" 4 ounces of broccoli and when you actually weigh it, you find it weighs EIGHT.
Get a cheapo electronic scale and use it to weigh cheese, meat, vegetables... even lettuce!
You'd be surprised at how little lettuce there is in 3.5 oz of romaine.
And MEASURE everything too until you get good enough to know what one fluid ounce, or a quarter cup of something looks like.
Final tip that has been an enormous help in my
weight loss over the last 6 months (43 lbs down, 27 to go).
I found a computer program called "Weight-By-Date" which allows me to design/record each day's meals.
It tracks/calculates the nutrients and presents the results of your efforts in colorful, easy-to-understand charts.
Take a look yourself:
www.weightbydate.comAnd no, I don't benefit in any way from that recommendation.
