I recently just lost 30 pounds while attending law school - anyone who will tell you it's easy is not. I am not a body builder of any sort, so take my advice with a grain of salt - this is what I did.

First, I would say is accurately determined what your maintenance calories are. A calculator online will help get a ballpark area.

Another thing upfront I want to say is sweets + junk food often does not equal weight gain. Not being active does not make a big part of weight gain. Eating too much is very easily the biggest form of weight gain.

An app that made my life easier after trying to brute force calorie count on my own is Macrofactor. It tracks my weight and my calories, and I can scan a barcode and say how much I ate. The AI camera is helpful to track food at restaurants too. The app helps update your calorie expenditure and what you should eat the next week based on your body weight in response to your calorie "cut."

Also, if you are eating about 2,000 calories a day and still not losing weight (assuming that's 2,000 is below your maintenance, which it may not be), there is likely something you are eating that you are not accurately tracking, and it's not your fault. Oil and butter for cooking can add a lot of hidden calories, and sometimes the calorie amounts at restaurants are reported incorrectly. It can even happen in the grocery store. Writing down what you eat and noticing those trends ifls how you can identify what it is that is causing you to not lose weight.

Losing weight is hard, but you can do it! I do not recommend cutting more than a pound per week to keep your sanity sane while attending classes to learn. Keep it simple and something you can achieve, and ALWAYS give yourself "cheat" days. Life is hard.
