why can I not loose.?!

Diary or it didn't happen.

Yes, if you want specific advice, you'll want to open your food diary.

I chart what i eat on mfp app on phone.

Yes, but your diary is private. We can't see what you are logging.

Are you gaining muscles with working out on weights? Do you have low metabolism? You should check your thyroid if you're not gaining muscles. But if you are gaining muscles and the amount of weight you can lift, bench keeps going higher, then maybe you need to measure other parts of your body to see if you are losing i.e. waist, hip, arms, neck. Sometimes, when you gain muscle and tone your body, you gain weight but lose inches.

Ok i opened up my diary. Does anyone have any answers. ?

What is your ht/wt, and how much do you exercise?

Unless you're under 5ft tall you're starving yourself. In the past 10 days (on the days you logged) you only reached 1000 calories twice, with one day at 604.

Something isn't right, if you are indeed eating that little (not knowing your ht/wt) you should have lost something....as dangerous as that low of caloric intake is.....

As others have said, gaining weight on that low of a calorie deficit isn't possible. Suggestion: be honest and log everything you put in your mouth EVERYDAY... even that multivitamin. Weigh/measure everything and decide if your goal will be net or tdee.

2. If you aren't already using one, get and use a food scale. Weigh all solids. Measuring cups/spoons are not accurate:

This.

It's all good advice. Follow this and you will lose weight.

I started on the suggested 1200 calories per day and found I had no energy to even live let alone work out! I;ve since adjusted my goals and eat back some exercise calories and I'm losing. I'm surprised you manage to exercise at all if you are eating so little.

Good luck.
