why am i not losing weight?

If you're not weighing your food, how do you know how much you are really eating?

Ten days isn't really enough time to say you aren't losing. Sometimes if you have just started exercising you will retain more water to repair the used muscles which will mean it looks like you don't lose for the first while.

Also, as said above if you aren't weighing foods out you aren't tracking your calories accurately and are most likely overeating.

Food scale. Stay dedicated to your diet. Lift weights.

Agree with above posts. Weigh everything solid and semi-solid (peanut butter, etc) and measure everything else. Give it time. It will happen.

I know it's frustrating, but it does come down to basic math. Calories in - calories out = weight loss/gain. So if your weight isn't budging, there's 3 possibilities:

1. Calories out is wrong: check to make sure that you've put the right information into MFP so that it could give you a correct calorie goal. Make sure your current height/weight is right, and that you haven't overestimated your activity level. Try calculating your TDEE on several different sites to get an idea of what the average says, and compare that to MFP's numbers with your average exercise added in. See if the numbers make sense. If they don't, there are plenty of people here who can help you set things up correctly. Also, if you are using an activity tracker, read reviews to make sure it's accurate. Some over or under estimate calorie burns, and then they adjust MFP with their incorrect numbers. And when you add in exercise, know that MFP overestimates...if you're not using a heart rate monitor for exercise, and are using MFP's estimates, don't eat all of those calories back.

2. Calories in is wrong: check to make sure you're logging everything, and logging it correctly. Measuring cups and spoons are nearly as bad as just eyeballing volumes for solid food. Get a digital kitchen scale. It's an investment of about $15 and it will last for years. You'll be surprised at how much a serving of cereal actually is. It's definitely not what your measuring cup says it is.

3. Both are right, but you're retaining water: we retain water for a number of reasons, including normal hormonal fluctuations (particularly for women), consuming more sodium or starch, and for muscle repair after an increase or change in activity. That last one is a big culprit for people starting on a weight loss journey. We begin a new exercise program along with our dietary changes, and then water weight swoops in and masks all of our hard work. It's frustrating, but fortunately it's also temporary.

Check out #1 and #2. If you can be sure that you're doing everything right, you can pretty much assume that #3 is the culprit, and then you just have to exercise your patience muscle along with all the other parts you've started working out You can retain as much as 10 lbs in water (or more) and your body will release it eventually. Things that can sometimes prompt this are to lower sodium and starch consumption for a couple of days and to take a couple of rest days from exercise. Some people even find that they suddenly lose a bunch of water if they eat at maintenance for a day or two, but I wouldn't suggest that this early on. Just something to keep in mind later on if you find you're at a plateau and you're sure you're doing everything right.

Good luck!

I think when you are just starting out, you do much better to try to prepare as many of your own foods as possible. Take a break from dining out and going for prepackaged/processed foods. Then you can accurately weigh and measure your foods and achieve a nice jump start on weight loss. Take the time to plan and buy your food for the week so that you have everything you require. Be patient with yourself. Plan a simple exercise routine that you can achieve daily ( even weekends). Every step counts and every bite counts. You need to double check that the programs you are using have the correct activity level and height, etc. to give you the right calculations.
Just for now, do the extra work and it will pay you back.
