Hello!  I am a registered dietitian and I thought I would try to answer some of your questions.

Assuming your resting metabolic rate (the amount of calories your body burns at rest, just to live, breathe, and function) is 1379 per day (based on your height, weight, and age) and your basal metabolic rate (calories burned per day when you include walking around and normal daily living into your resting rate) is 1763 (calculated).  You are probably burning around 700 calories per day (give or take) with 1 hour of cardio and 30 min of strength depending on intensity.  So you are burning 1763 + 700 = 2463 calories per day.  You are eating 800 per day which gives you a total deficit of about -1663 calories per day. 

To burn 1 pound of fat is 3500 calories.  You want to lose 30 pounds which equals 105,000 calories.  105,000 divided by 1663 calories burned daily is 63 days which is about 2 months.  Unfortunately it isn’t always so mathematical and you can hit plateaus or slow your metabolism, etc.  But I think it could take 2-3 months to lose 30 pounds doing your current regime.

Now the dietitian in me ๐Ÿ˜‰ Be careful since 800 cals per day isn’t always maintainable and can seriously slow your metabolism.  I would try to add healthy calories (lean meats, whole grains, healthy fats) in once you reach your goal and maintain your weight at about 1100-1200 calories. 

Good luck and I hope my rambling helped a little bit!  Let me know if you have any other questions ๐Ÿ™‚

You look great!  Don’t get set into a goal number – when you feel good about yourself, that’s the weight that matters.

The quick loss you have won’t stay quick.  You’ll get down to 1-2 pounds a week, which is healthy.  Make sure you lift weights in the gym, because thats what will tone up any fat, and also metabolizes fat faster. 

Good luck!

Unfortunately it isn’t always so mathematical and you can hit plateaus or slow your metabolism, etc. 

That is a really important consideration. As OP loses weight, her resting metabolism is going to slow down and would have to be recalculated. Not to mention, if she is continually feeding her body only 800 calories a day, her body is going to adjust to the lesser calories and slow itself down- which means she’d have to drop her intake even lower. Not to mention I don’t think you can, under even the best of circumstances consider weight loss a completely linear model, where a a daily 500 deficit equals 1 pound of weight loss per week.

Exactly…weight loss is ALL an estimation game.  Everyone’s body is different and will react differently.  She didn’t want a lecture so I just gave straight numbers to put it in perspective.  Can you lose weight doing what she is doing? heck yeah.  Is it long term maintainable? usually not.  But that’s not what she asked.

I really don’t notice a difference in weight between the two photos. Especially since you’re wearing the same top and there’s no difference in how it fits.

If you’re only eat 800 calories a day, then make sure you are eating real food that is well-balanced. You should also probably take a multi-vitamin.

Have you looked into Intermittent Fasting.  I’ve read a LOT of good things about it and its many health advantage, not to mention weight loss.  So far the research I’ve done on it shows that this is a more healthy way to lose weight and a more successful way.

For women, they recommend a 14/10 fasting schedule, which would be 14 hours of fasting, and then a ten hour window for eating–sleeping hours count as fasting. They say it takes about 4 days for your body to get used to this method of eating  

Of course, as with everything, you have to listen to your own body. If you feel stressed or exceptionally tired or any unusualy symptoms while doing intermittent fasting, STOP! and get something to eat! Just make sure it’s real food–none of this low-fat, low-calorie plastic health food. 

I’m giving this a try this week to see if it will help me get past my current plateau.

Good luck!  

And By The Way, I think you look fantastic in both pictures!

I honestly believe you would lose more weight, or at the very least, keep it off longer if you ate more calories. If you don’t eat enough to cover your day-to-day activities your body will slow down your metabolism to compensate for it.

I’m still learning the ins and outs of weight loss myself so I can’t really provide any good advice. But, I want to say that you look great in both photos! And…when I was on Depo, I had the same horrid results. Ugh!

Considering the different angles of the pictures and the big hair in the first one… I really can’t see much of a difference. I think you are more likely to feel it and see it then other people, so if you want to lose weight then I won’t tell you not to do it, but from an outsiders point of view you don’t actually look any better at the lighter weight.

That out of the way (and i am refraining from JESUS CHRIST YOUR DIET IS PAINFUL TO EVEN IMAGINE) i’m just going to say that once you start going back to eating KFC and all of that you will gain the weight back. You are effectively starving your body and when you return to eating a normal amount of food (once you hit your goal weight) you are just going to put the weight back on. I’m going to echo PP and say you should try and have 1200 calories of good food such as lean meat, vegetables and whole grains if you really want to reach your target and keep yourself there.

I would up the diet from 800 to 1000 calories because at 800 calories you’re probably going to slow your metabolism down. 

To compensate, I would increase your workouts.  I know you’re already doing cardio for an hour and weights for 30 minutes, but you just need to burn 200 more calories a day to make up for the extra 200 calories, so add some cardio to that. 

I would also split the workout.  Do half in the morning and half at night.  This will keep your metabolism pumping all day long.  You can probably do 30 mins of cardio and 30 mins of weight training in the morning followed by an hour of cardio at night, or the other way around.

If you work out in the morning and do cardio, eat a casein protein (eg, cottage cheese) at night and don’t eat anything for breakfast.  This will have your body target fat instead of muscle. 

Drink a protein shake after your weights workout to make sure you build the muscle. 

If you build your muscle, you will probably look like you did at 110 but it will be at 115-120.  Muscle weighs more than fat and thus takes up less space. 

And, since you’re working out and building muscle, your weight loss on the scale might slow down.  That’s not because you’re not losing weight, it’s because you’re building muscle.  You should really only measure your weight loss by measuring yourself with a tape measure in inches at your arms, waist, hips and thighs, and maybe by looking at a body fat scale.  You can use a regular scale, but it won’t be as telling.

ETA:  Also, are you using the same scale now at 140 as you did at 110?  Because I am trying to get back to what I looked like when I was 108 (I’m 5’2) and right now I’m about 135 and I definitely look heavier than you by a LOT.  You don’t look anywhere near 140lbs, I wouldn’t have thought more than 125.  If you’re using a different scale, that might be a factor, too.  All scales weigh you a bit differently, even 5+ lbs different.  I know my friend used to weigh herself at the gym and she would be 111, but at home she was 103. 

ETA2:  Finally, if you really want to know how much you’re burning (no offense to PP, but 700 for 90 mins of workout seems like a lot, especially since you didn’t specify what type of cardio or your intensity), you can get one of those heart rate monitors that have a calorie calculator thing.  They’re expensive, but if you really want to know how much you’re burning in your workouts, that would be the way to go.  You can also google an activity calculator and have it tell you.  Running at 5mph steady for 60 mins on a 140lb person burns 500 calories according to one I found online.  So, once you start to lose weight, you’ll be burning less calories for the same workout.
