WTH am I doing wrong?

I think patience is the key. I think to expect big changes in 10 days is a lot. Also, when you start a new exercise program you retain more water for up to a week or more. I think most people would agree to wait approx 4 weeks to see changes, then reassess at that time.

I'm 5'7'' and 230lbs (so, obese). I have a daily calorie goal of 1400 and I'm always around 200-300 under that. I'm never hungry bc I eat several smaller meals throughout the day. I have been busting my butt doing Jillian Michaels 30 Day Shred every morning (10 days straight) and additional cardio (elliptical 18 days straight) and strength training (bowflex). I haven't dropped a single ounce in a week. I also haven't lost any inches in my arms legs, or waist. I just looked at my Day 1 pics and my Day 10 pics and nothing has changed! Please help if you know what's going on!

One week is an insufficient amount of time in which to judge your progress. Your approach seems rather masochistic and uneccesarily harsh. If you are 230 pounds 1100 calories is way way to aggressive of a caloric deficit especially if you are exercising as much as you say. You should be eating something like 1800 calories not 1100 and even that is aggressive.

Why are you eating so little?

Please eat your whole 1400 calories - under eating that is not doing you or the new muscles you are trying to build any favours. The set calories you are given already has quite an aggressive calorie deficit built in to it if you are 5'7 (my height).

Weigh all your food.

When you are setting up your new eating and fitness routines, try to remember your weight gain took a fair chunk of time to progress. Your weight loss should also take you a fair and healthy amount of time to happen. Please try to set things in a way that is enjoyable and achievable, not something that you set yourself up for failure by going too hard and too fast and expecting to drop 10 kgs in a fortnight because you want it to be gone

Make your fitness regime something that you will be able to continue rather than something just to shred the weight off, then cry in your weetbix when you stop and it starts to creep back on again.

When you reduce your calories to such a low level, your body assumes that you are starving and starts shutting down functions. Net result is a plateau. Do some research and find out how many calories you should be eating to maintain weight. Probably in the 2300 calories per day weight. Then eat about 500 calories less per day. After 7 days x 500 calories = 1 lb. per week. Now, if you exercise on top of that, you have to eat more. You say that you are eating 1400 calories - 300 calories = 1100 calories. Definitely, your body thinks it is starving and your metabolism slows down. Believe me, I've been where you are. The best way to reset is to go off diet for about 3 days, eat normally then go back on the diet and eat enough calories to offset your exercise. I'm about the same size as you. I lose my weight best at around 1700 calories. If I go below 1600 calories, I plateau and stop losing. I found out a lot of this stuff on the internet. I did a lot of googling and read a lot of other people's stories before I clued in to what I was doing wrong. Good luck! I hope this helps you.
