What am I doing wrong?

It'll help if you open your diary-- if you're under your goal by 300 often you might not be eating enough. Most likely though-- you're doing P90x, which means your muscles are tired and retaining water to repair themselves. And also it's only been a week. Be patient, and open your diary if you'd like some more specific comments.

edited for grammar :blushing:

You're not alone...it's sooo frustrating:( I'm going to check my inches too as suggested maybe that will keep me motivated...

You should try to eat your calories. Your body is probably going into starvation mode and holding onto fat. I heard p90x is a great workout program(thinking about trying it myself) . I heard it burns a ton of calories, I bet if you start eating more, as your muscles recover the weight will start falling off! Let me know how it goes. Keep up the good work, and don't get discouraged!

How long have you been doing P90X? I am a grad of it and can help with any questions you have. What are your calories set at right now?

I was stalled at 170lbs for a year! I worked out 5 days a week, doing cardiovascular, weight training, the elliptical 4 miles in 40 minutes and on top of that was doing the Insanity workout 3 days a week. My problem turned out to be my birth control. I finally stopped the depo shot, and it took a few months to completely wear off, but once it did I lost 30 lbs in 2 months without doing anything more than walking my children to school. I don't know if this might be an issue for you, but if you are on birth control you might want to find out if it can affect your weight and maybe find a better alternative.
Also, try eating a bunch of small meals a day. Try high protein meals for breakfast. Egg white omelets for broccoli, onion and cheese. And you should be taking in a lot of calories to support your workout burn. Its ok to go over. Whats more important is where you get the calories that cause you to go over. Like, going over with 200 calories of salad is a lot better than going over with 200 calories of ice cream. There are good calories and bad calories.
And also, I would start charting your measurments. Although I didn't lose any weight, I did lose inches and notice a difference in my body shape. Good luck! It'll happen. Be patient. One day at a time!

Thank you for that! I am not hungry at all, so when I hear that I need to eat more, I simply can't do it!

If you have more to lose, a larger deficit might be ok. But if you're netting less than your BMR, then you should try to increase it unless your Dr is monitoring you. That program is pretty hard core-- your body needs fuel. But if you've got larger fat reserves then a larger deficit won't hurt you until you get smaller.

You should take your measurements. Muscle weight more than fat. If you are not losing inches or your clothes not starting to hang on you then you can say you are doing something wrong. I hardly ever gauge my weight lost by the scale

when are you weighing yourself, if you are doing it after a workout your muscles could be retaining water making you weigh more. Try to weigh yourself when you first wake up not after eating or drinking anything. Don't give up, it may take some time, but will be worth it in the end.

Staying under your dally calories is not the answer. Your body needs the calories in order to lose the weight effectively.

P90X is designed to build muscle, which is more dense than fat. There's a good chance you're losing fat and replacing it pound-for-pound with muscle. If your measurements have gone down, then that's probably what happened. As for your calories, unless your 300 kcal deficit puts you in the 1200-1500 kcals/day or less range, you're probably fine. Anything below that and you might be starving yourself, which will hinder weight loss.

I agree with the others....you need to try to eat closer to your calorie allowance. OTherwise, your body will think it's going into starvation mode and hold on to weight. You say you don't want to eat more because you're not hungry. But perhaps try adding just a bit more to each meal? (IE add 1/2 serving more cereal in the morning or an extra piece of fruit in the afternoon.) Don't aim to add the extra 300 in one sitting but just spread it out a bit more? Also, muscle weighs 2x the amount of fat so you could be adding muscle. Using your measurements will help you see the difference, I'm sure!

You're doing great!!!

your body will take longer then a week to change. i promise, just keep it up, and you will see a difference/.

You should try to stay under your goal by about 100, not 300. It seems paradoxical because weight loss is founded on the theory that you need to burn more calories than you consume, but your body is more complex than that. If it's not getting what it needs, it will save more and use more energy coming from lean body mass (since our body likes fat more than muscle) to burn energy, which is exactly what you DON'T want. You want your body to burn fat, and to do that you need to be careful - stay on a reasonable caloric deficit. MFP already factors in a deficit percentage (if you ate exactly the amount of calories it sets your goal at, you would still be burning a good amount more than consuming - around 10-15% I believe).

There are also other factors that go into your weight...as said before, water retention (high sodium leads to water retention, as does the beginning stages of intense weight lifting)...you can also be putting on muscle mass, which weighs more by density than fat. You have to look at your progress by month rather than by week, which is annoying but necessary.

Thank you for that! I am not hungry at all, so when I hear that I need to eat more, I simply can't do it!

Try a handful of nuts after exercise. Or a protein shake. Or a spoonful of nut butter.
