Gaining Muscle - no fat loss

Bodybuilders typically have a cutting and a bulking phase. During bulking they know they need excess calories to build good muscle but with that comes adding fat. So they will then cycle to a cutting phase where they want to shed that fat and hold on to as much of the muscle at the same time.

To drop fat you need to be in a calorie deficit
To gain muscle you need to be near or over your TDEE.

Rather than simple loss mode or gain mode you can break it down further.

1. Concentrate on fat loss only - aim for 25-30% TDEE reduction and accept any minor muscle loss
2 - Concentrate on fat loss with minimal muscle loss - aim for 15-20% under TDEE with a solid macro ratio
3 - Concentrate on no fat gain and small muscle gains - aim for TDEE with solid macro ratio and adjust +250 cals on the daily TDEE and track and log the result
4 - Concentrated bulk with accepted fat gain with muscle - Solid macro split with +20% on TDEE

I am super frustrated.

I've been trying to loose weight for over 10 months, and little has happened. I am switching to a mostly vegetable diet, but with little results.

Anyway. I've begun weight lifting... and I have gained a lot of muscle... but I just feel like I'm not loosing any fat. The scale won't budge and my measurements are the same as nine months ago!

Nothing is changing despite muscle building. I am feeling myself just giving up on trying to loose weight. My thyroid is fine... and its just... the weight won't come off no matter what I do.

Edit: But I will say that my clothes ARE fitting much better... I'm just stumped.

If you are eating at a deficit you are not building any muscle outside a pound or two of newbie gains. You normally lose muscle when you try to lose weight. You need a calorie surplus to build muscle.

If you aren't having results... change what you are doing. Eat at maintance for a week or two and than drop back down. Change the exercise you are doing. Exercise longer... do a different exercise. etc.

Keep the weights
Keep cals constant
Introduce 30 minutes of any form of cardio you like 3-4 times a week if you are not doing any
Invest in a decent activity tracker and ensure you keep you daily activity (moving, walking, standing etc) as high as possible
Give it 4 weeks
Assess results
If it doesn't work or is slow drop cals by 10%
Repeat
Assess

You'll find your calorie sweet spot eventually....

I've lost over 20 pounds, my clothes fit much better but my waist/hip measurements haven't changed. I've lost a lot of fat all over and from my belly (in between hip and waist lol) so the difference is visible, which it might not be to you if you've lost 8lb. You probably need to be measuring fat with callipers or something to be sure of the difference.

You don't have a lot of weight to lose but also you're in calorie deficit a lot of time time - and bear in mind your calorie goal already has a deficit built in, so *you need to eat to it* or very close. If you feel more comfortable working to a deficit then set your weight goal to maintenance and then you can be short 500 cal a day without a problem. But this is likely why you're not losing weight or gaining much muscle.

The donut is really out of character for me. Sugar is in general. I usually eat fruits. I haven't touched fast food in over a month or so. The only packaged food I eat is some fiber snacks and frozen vegetables or fruits, but even those are rare.

And Monday (sunday?) It says I had to finish off 420 calories, I ate those later and forgot to log it in.

I will eat up to my limit, but if I exercise that day (usually burning 240-300 calories in cardio alone) I swear I start dying of starvation.

I am so lost and hopeless.

If you exercise then you should be eating back your exercise calories. That's why when you log x calories burned during exercise that amount is added to your total daily goal. Eat them back, it will help fuel your body so that you can keep doing exercise.
