What is going on with me?!

Do you use a food scale to weigh your food? If not, you're most likely unknowingly logging inaccurately. Cups and tbsp just aren't precise enough measurements for solid food.

As well, if this is a new workout routine, your muscles could be retaining extra water.

You'll get there! Give it time!

It could be the water retention them. And even though it feels like it, 15 days isn't that long in the big scheme of things ... Although trust me, I know when you're working really hard and making good choices, it feels like an eternity for "no" results. I'm pretty sure everyone on here has been or will be where you are at some point.

Have you been measuring yourself? Maybe you've lost some inches? Do you feel stronger? Those are all important as well

If you're really doing everything right, you just gotta stick with it.

I'd say maybe water retention too. I've heard it does take a few weeks to actually see weight loss though if you are small already and only need to lose 20 or less pounds. (Not sure of your specific goals) Maybe you need to switch up your macros to better fit your personal body needs. Sometimes you have to play around with them to work for you in the long run.

Give it time! It's taken me since January 2015 to lose around 33 pounds. Last August I only lost two, and I weigh everything and work out at least 3 times a week. It takes a long time to see the changes, and 15 days is really not nearly enough time. Just keep at it!

I think you're overestimating the calories you burn doing exercise. 40 mins of walking isn't burning 330+cals. If you were running, maybe... 40 mins of circuit training isn't burning 430 cals either. Don't use what MFP tells you exercise is worth.

Just stick with your plan - don't eat back your exercise calories and check out the following:

Pay particular attention to this one - quite possibly the best on MFP:

Water retention will go away in ~5-7 days. Increased water intake is not going to help you lose weight faster, but it is good for several other reasons. If you aren't losing, you are not in a caloric deficit, so look to your logging carefully and figure out what you are missing. Most of all be patient and don't get discouraged. Weight loss is not linear. Focus on the other positive aspects of your new routine - increased endurance, strength, body composition, etc.

I am so discouraged! 15 days of consistent circuit training and walk/running (5-6days weekly) and MFP tracking with ONE single day over my calories and ZERO lbs lost. What the H?! Please help

I suggest giving it more than 15 days. Patience is a virtue.

Ensure that you are indeed not underestimating calorie in and overestimating caloires burned (weigh you food, log everything you consume, and eat only about 75% of your exercise calorie back) and then come back in a month and report back in four weeks.

Nope. It does't happen that fast. Building muscle and strength takes more than just six weeks.

Its either water retention or I have experienced myself where you reach a plateau and you have to mess around with the macro units and also hit cardio harder instead of the circuit.

What are your stats and what is your daily calorie goal?
