What am I doing wrong!?!

Honestly, I think your calories are too low. Sounds like your body could be starving and storing fat

No. That's now how it works.

If you eat too few calories, you lose weight.

OP, you are losing weight at a healthy rate. You probably need to be patient.

NO...your body will go into starvation mode and store fat, which will not go away easily.

Not exactly. If you eat too little, your body will lose fat AND muscle. Your total fat will not increase if you eat at a deficit, but your BF% will likely rise.

Thanks for the clarification! Like I said above, I am no medical professional...just going off what I have been told by my docs.

Eating too few calories will not make a person's body store fat. However, I do agree that the OP is not eating enough if she actually is netting as little as she says. OP, please make sure you are giving your body enough calories to fuel itself. Severe calorie restriction can cause nasty health problems.

Your body won't think you are starving unless you go days without eating anything. If you eat less calories than you burn, your body will use stores of fat to make up the difference.

3,500 calories = 1 lb of fat...

So, if you run a deficit of 500 calories per day, every day, in one week you will lose 1 lb of fat (500 cal x 7 days = 3,500 cal). Or, if you run 250 cal deficit every day, you will lose 0.5 lb of fat every week. Very simple, but the discipline is not easy. If I don't find myself a bit hungry at times during the day (I'm doing a 250 cal deficit/day), I know I'm eating too much to be losing weight.

I would also check your "Goals" tab and update it regularly. I've found that mine does not keep up with my weight loss the way I would expect it to. For example, as you lose weight, your daily caloric needs drop also. If the MFP does not update properly based on your check in weights, you'll keep eating the same calories you started at, which becomes too high for weight loss for the weight you are now at (it will be more like maintenance caloric needs, where you maintain where you are at).

It can be complex, but you are on the right track. There will be days where you don't see progress. The body works in mysterious ways. For example, I recently read a post by someone who wanted to drop some weight and could not. He changed his diet slightly (dropped certain types of carbs for a couple days, not sure which ones), and through exercise he used up a bunch of stored glycogen which made it easy to drop a bunch of water weight that was keeping his weight up. I can't explain any more than that, but the point is don't get discouraged.

Yeah, that net is crazy low. I know it's a "to each his or her own" thing, but I lost 21 pounds netting at least 1400-1500 a day.

I should say: EATING about 1800, but netting about 1500.

Per those numbers, your BMR is 1630 calories/day, if you do nothing but rest. At the least, MFP should have you at close to 1950 calories/day to maintain that weight. Assuming that, with no exercise, you should be eating 1,700 cal to lose 0.5 lb/week (0.25 kg), or 1450 cal to lose 1 lb/week (0.5 kg). The most I've seen recommended is 2 lb/week (1 kg), so that would be 950 cal/day that you could eat. I think you are doing fine.

If you find that after exercise your NET calories are consistently lower than 950 day, look at switching to some higher calorie foods (if you find you are not hungry)...

Drinking about 1.8 liters of water a day. Could I just do a less exercise and eat about the same or should I continue with the same exercise and up my cals? Or can I just continue with what I'm doing because I'm just not hungry enough to eat more. I actually eat a lot but it all low calorie foods. I've been doing measurements of hips, waist, chest, leg & arm and have lost cm on all except chest in the past week but no actual weight loss on the scales. I'm 168cm, 84kg & 29.

You should net atleat 1200 calories, whether that's by eating only 1200 calories with no exercise or exercising and eating back your exercise calories to net 1200.

Honestly, I think your calories are too low. Sounds like your body could be starving and storing fat. You may want to mix up your work-out routine and try some high intesity exercises like running, kickboxing, or cross training. This may confuse your body and take you off your plataeu.

Really? She has lost 6 pounds in the last 3 weeks. She is NOT on a plateau!

OP- Just be patient and keep doing what you are doing. Some weeks you lose, some you don't. And average of 1-2 pounds a week is great.

OP is netting 800 calories.

Telling her to "just keep on" is horrible advice.

I lost more than 60 eating more than that. Your body is not getting enough fuel.
