Please help - open diary. Not losing :(

You have a LOT of things like 1 brownie, or 1 sandwich, one portion etc. Where are you getting these numbers? Are you using the recipe builder? Also, generic items are not accurate and should be avoided. What is going on with Saturday that isn't logged?

As for exercise. Exercise is just that. Cleaning is already considered in your activity level. Your fitbit should be accounting for this. Do you have negative calorie adjustments enabled?

Good for you for weighing all your food. Just at a quick glance at your diary for the past week or so, I noticed quite a few foods have sodium at 0 -- so maybe your sodium is higher than you think, and you're retaining some water? For example, there was a fish and chips meal and a homemade pasta-type meal with 0 sodium -- I know that those types of foods and any pre-packaged meals are usually pretty high in sodium. Even lower-sodium broth that I use for homemade soups, etc. have quite a bit. Just a thought, especially if you're just starting out!

~Don't use "compound" foods. If you have cereal and milk, measure and log them separately.
~Always weigh solid foods in grams. "1 cup chopped onion" is useless.
~Don't trust serving numbers. "Aldi rice pudding 1/2 tin" or "Kinder - 2 bar" is useless. Weigh it and do the math.
~Ensure your loss goals are realistic and you're honest about your level of activity.

50lbs to go isn't a huge number; it's big, but not gigantic. You may already be to the point where you have to be tight with your logging. Log everything that goes into your mouth. If you're close on your calories, don't eat food you didn't prepare, because you have to guess on what's in it. A little added sugar or fat can put you over your calorie goal.

One thing I noticed is that for meals out you might be underestimating them. For instance, a standard order of fish and chips could come in well over the 695 you have logged. I know I can sometimes be guilty of wanting to pick the entry with the lowest calories, but I've started making myself look at a couple of entries and then pick the calorie amount that seems to occur the most, or lean towards the higher end just to be safe. Also, generic entries can be very misleading and not very accurate.

As others have said... don't use generic entries. Your cereal, for example... weigh it dry, then measure the milk you put in instead of using the entry that has milk included (how much milk is it?).

You say you're weighing but you use volume for peppers or broccoli, you use generic entries like 'sweet potatoes' (is it cooked or raw?), 'homemade' entries that could be totally inaccurate (make your own recipe and use the recipe builder) etc.

Basically, you're probably underestimating your food because of lack of accurate logging.

First- Your dogs are absolutely adorable!

I'll echo what some others have said, you have a lot of generic entries. Your special K with skim milk, is that an entry created by you or another user. If its by another user, it may not be accurate. I don't see any drinks logged, are you drinking just water? Liquid calories can add up pretty quick.

I noticed that you logged cleaning as exercise. It is something that is already built into your activity level so it shouldn't really be logged.

Invest in a food scale. You can get a pretty decent one from Amazon for around $10-15. Weigh and measure all of your foods and liquids.

How long have you been at it? What is your current weight, goal weight and when did you last see a change on the scale? If its been more than a few weeks, then something clearly needs to change. Calories in and calories out are where you want to assess for improvement.

1) Many days you have a low or 0 Fitbit calorie adjustment. If you are not wearing it all the time, ignore this comment. If you are wearing it all day, every day: the constant 0's mean you are not as active in real life as you told MFP you would be. Lower your activity level in MFP OR move more.

2) Stop logging the work-related activities as exercise. This is part of your regular daily activity level in MFP. And if you're using the Fitbit, you would only need to log exercise if it is not step based. Like swimming, biking, etc.

3) Be more accurate in your food logging, in terms of weighing foods and logging accordingly.

4) Assess your goals. I'm not sure of your current/goal weights, height, etc.

For me Fitbit has been fairly accurate. I've used it for almost 2 years. I have the One and in my opinion its the best model. My son tried the Flex for a while and found that it would count steps when he moved his arms and would not count steps if he walked while holding things. (His arms needed to be swinging for it to count while walking.) So I don't know if your Flex is accurate.

I think everyone is right. I havent been making the progress I want and I think its from inaccurate measurements so just last night I started weighing foods. Just dinner so far but I was surprised at the difference of what I thought it would look like vs what it was. I'm hoping to work harder each day this week to be as accurate as possible. You should look into what everyone is saying, especially if you use entries that have missing info. If something says zero sodium thats a warning sign that a person created the entry and was wrong. I have started cross checking entries before I use them. With chicken, I was measuring it chopped and by the cup. The entry I had been using didnt have the correct fat or protein aftet I checked it against another source. Check it all, its the only way to be sure.
