Getting frustrated

Weight loss comes down to calories. It makes no difference what foods you ate or didn't eat. In order to lose weight a calorie deficit is needed.
How many calories are you eating ? Have you used a food scale to weigh ALL YOUR SOLIDS and a measuring cup to measure your liquids ?

It sounds like you're not eating enough. You need food for fuel and it sounds like because you are under the recommended caloric intake your body is hanging on to the fat. I had the same problem and kicked up the caloric intake to the recommended calories and dropped 12 lbs along with exercise of course. Give that a try

1. If it's been less than 3 weeks or so, don't sweat it! Normal fluctuations happen and unfortunately sometimes we stall for a week or two even when we're doing everything right. Give your body some time to catch up with the changes you're making.

2. If you aren't already, be sure that you're logging everything. Sometimes people forget about things like veggies, drinks, cooking oils, and condiments. For some people these can add up to enough to halt your weight loss progress.

3. Consider buying a food scale if you don't already have one. They're about $10-$20 dollars in the US and easily found at places like Amazon, Target, and Walmart. Measuring cups and spoons are great, but they do come with some degree of inaccuracy. A food scale will be more accurate, and for some people it makes a big difference.

4. Logging accurately also means choosing accurate entries in the database. There are a lot of user-entered entries that are off. Double-check that you're using good entries and/or using the recipe builder instead of someone else's homemade entries.

5. Recalculate your goals if you haven't lately. As you lose weight your body requires fewer calories to run. Be sure you update your goals every ten pounds or so.

6. If you're eating back your exercise calories and you're relying on gym machine readouts or MFP's estimates, it might be best to eat back just 50-75% of those. Certain activities tend to be overestimated. If you're using an HRM or activity tracker, it might be a good idea to look into their accuracy and be sure that yours is calibrated properly.

7. If you're taking any cheat days that go over your calorie limits, it might be best to cut them out for a few weeks and see what happens. Some people go way over their calorie needs without realizing it when they don't track.

8. If you weigh yourself frequently, consider using a program like trendweight to even out the fluctuations. You could be losing weight but just don't see it because of the daily ups and downs.

9. Some people just burn fewer calories than the calculators predict. If you continue to have problems after 4-6 weeks, then it might be worth a trip to the doctor or a registered dietitian who can give you more specific advice.

I looked back through your diary and there are numerous days that you haven't logged a single thing. The first step is to make sure you are logging everything you eat. A food scale really does come in handy!
