First things first...while eliminating sugar, pop, fat, and carbs is healthier for you, it will NOT net weight loss if you are still eating a surplus of calories. It just simply will not. Adding in exercise will NOT net weight loss if you continue to eat a surplus of calories. That is the biggest mistake we make when we start out trying to lose some weight. We are always told "eat less, move more" and the pounds will suddenly disappear. Not so much. While the basis behind this theory hold true, there is a LOT more to it than just that.
When you do a quick search, or even talk to your doctor, every thing points to you wanting to measure and weigh EVERYHING you eat. And all the materials out there indicate that you need to eat between 1200-1500 calories to lose weight. But if you are 40 years old and 5 foot nothing and don't exercise, 1500 might be TOO much! And if you are 23 years old, 5 foot 9 and work out three times to four times a week, 1200 might be TOO less! 100 calories can make or break success.
When you weight and measure...count your calories. It really isn't that hard. Go to MyFitnessPal, open an account, and ENTER your foods. This amazing thing happens...it logs your calories. AMAZING! You see, there is no need to carry around pen and paper and a book that lists it all. Just enter your food daily. You don't have to do it forever...just long enough to figure out exactly what you eat every day. And that stick of gum you just put in your mouth? Log it. It DOES have calories. It DOES have carbs. The manufator just isn't required to list it because it is less than 1g. But 10 slices a day can be as much a 9.9 carbs a day. That adds up, quickly.
Now that you know how much you eat, you need to figure out if you are eating enough or too much. Go get your BMR and RMR. Go HERE
for an easy calculator (and it also explains just WHAT you are looking for.) Be honest with yourself on your activity level. This is important. When in doubt, go one down. Whatever number it gives you is your maintenance number. That is what you need to simply maintain your current weight. Subtract 500 to 1000 calories from that number to get the amount of calories you need in order to lose weight.
It takes a 3500 calories, plus or minus, to make or break a pound. At 500 less a day, you should see an average of 1 pound a week. If you are honest with yourself. If you are honestly counting your calories. If you are honestly working out (for what it is worth, weight loss is 90% what you eat and 10% exercise.)
Once you are educated, weight loss really isn't all that hard. It is nothing more than math. And those stalls you hit every so often? Think of your body and your metabolism as a two year old child. Every now and then, it has to nap to recharge. When it wakes back up, it will run full force again. If you detour on your plan when you stall out you are just going to have to start all over.
And if you are getting tired of starting over, stop quitting. It was never said weight loss was easy. It was said it was worth it.
Vent over and out.
ETA: Check your BMR and RMR often, after every 20 pounds lost or in an change in activity longer than 2 weeks. It WILL change. And excuse all errors...typing from a itty bitty netbook



I cannot in good faith come to the boards and seek yours and any of my other 3fcers advice without being honest about what I already know to be true about my eating habits.
