I'm Over 200 lbs and CANNOT lose weight!!

First of all, congrats on your progress so far!

Second, you absolutely CAN be gaining muscle since you joined the gym. I am in pretty much the same boat. Lots of weight came off with minimal effort, then nothing, even though I started working even harder at it and joined a gym. My suggestion would be to see if your gym offers an assessment that includes body fat %. I was stunned to see that I had gained a pound (I still have 60+ lbs to lose) but, according to the machine, I had lost 8 lbs of fat, gained 4 lbs of muscle, and the rest was water -- which is now gone since I'm staying hydrated. So, it is possible.

That being said -- stay hydrated! Keep a close eye on your calories. Eat enough (within your range) but not too much. Everyone here has offered good advice, just experiment with it. Try slowly upping the calories one week and see what happens, be sure to track your exercises (highly recommend a heart rate monitor!) so those calories are factored in. If that doesn't work, try lowering your carb count -- eat more protein and veggies. Experiment with it. We are all different so there is no one-size-fits-all solution. Most importantly, never give up! You're doing great.

You are not losing because you are not in a deficit. I agree with all the others who said get a food scale.

At first you tend to lose a good amount of weight and yes it does slow down after a while, this is NORMAL. You need to change up your exercises. I also see you are not having enough protein in your diet, its very important as it helps your muscles stay healthy and strong. Having low or no protein in your daily lifestyle over time isn't a good thing. You will lose weight even if you don't eat much protein obviously but some of this will be muscle not just fat and water. Make sure as the others have said to measure and weigh your food and even oils, butters ect Keeping your muscles strong by eating enough protein and doing what you are doing by the strength training will help with those stubborn lbs Good luck

My ideas of enough exercise and weight are different than most peoples because I run marathons (I've run 8), so for me, an hour of exercise should be normal or minimum, plus a minimum1.5-2hour long run on weekends (about 13 miles). That being said, If I look at it from the perspective of someone not training but just getting into shape, I would say you need to do more cardio. 25-30 min a day won't cut it. Try for AT LEAST 45 MINS. Even at my heaviest (which was 180,I am 155 now--i am only 5'3) I would do at least an hour- and I was just getting started. I am 36 now---older than you--- and 25-30 mins for me is just a warm up. Granted, this is after years of training.
Still, 30 mins is below recommended daily levels for exercise anyway by the govt standards--but it is a GREAT start, esp if you were inactive before. Now try to challenge yourself and push it. Also try to really be accurate in your food diary as others have already mentioned.

bump for future reference. Thanks

I would say Weigh your food for example I was logging a apple as a medium apple at about 55 calories and when I got my scale it was actually 102 calories and the apples are pretty small. It is impossible to determine how many calories your eating without a food Scale. And congratulations on your loss so far!
