Need a diet/exercise critique ... come on out experts!

Your food choices are poor, and your calories are too low most days.
Eat back your exercise calories or your metabolism will stifle.

MFP has calculated our total calories required each day WITHOUT exercise to lose 1lb per week.
And after we log in our exercises, our calorie limit goes up.
Why?
Because it's telling us to eat our exercise calories.
Large deficits are unhealthy, because while you will lose weight, what's the quality of the weight loss?
In many cases you'll lose lean body mass - MUSCLE - which LOWERS your metabolic rate, making weight loss harder.
Then you have to lower calories even more to compensate, and the cycle continues.
Be smart.
Exercise well both cardio and resistance, and eat back the calories.
The exercise will RAISE your metabolism and burn more fat at rest.

This exactly!

I would say no don't freak out (but I'm no expert! lol)... from the sounds of it your gaining muscle which weighs more! Give it time and that muscle will eat away at the fat and you'll see the numbers go down on the scale. As for your calories I'm not sure...

Very unlikely that she gained muscle weight in 2 weeks...

I took a peek at your diary also, need to take a real look at that if you are lifting, light of fruits and veggies, most of the weight lifters seem to recommend the 40C /30 P/ and 30F for lifters so you might want to research that. You need lots of different nutrients, and it's a life change switch so you have to find foods you like, balance your macros (Protein, carbs, fats, etc) if you have the app on your phone go to the nutrients page, it will show you super fast where your weaknesses are. Lifting is a high stress exercise for your body and can cause a lot of water retention at first as your body mends the micro damage to your muscles after the workouts so some of it might be water. I would say you have a bit of research to do on yourself. Have you calculated your BMR, BMI and your lean body mass, the protein levels you need are based on 0.7 * lean body mass not total weight. You might want to get all that done then make some decisions about your nutrients.
Anyway, there's some ideas.

I agree with the water retention. If you just started a new routine with the lifting, the muscles are holding onto the water. Keep doing it and give it a week or two for your body to adjust!

I'd agree with this and to answer your question about improving your diet I'd agree with the others and say stay away from prepackaged processed foods. They're convenient in a pinch but the majority of the time try to stick to fresh fruit and veg and things made from scratch from fresh ingredients. I usually cook extra at dinner so I can take some to work for lunch the next day. Or at the weekend cook a big batch of something and then freeze portions so that on the nights you can't be bothered cooking you have a healthy "ready-meal" good luck!

I haven't read everyone's reply but I would suggest checking and measuring your body composition and adding circumference measurements to your weigh-ins. Weight is only part of the story and I think you should gather as much information about how your body is responding to your training and nutritional program before you decide what course of action to take.

More protein and fiber? I'm suggesting these two things because this is what tends to help keep me full longer so that I'm not making terrible food choices and just grabbing whatever is convenient when I'm hungry.

My struggles are simmilar right now, I suggest(and this is just a suggestions I am not a doctor) get a heart rate monitor to track your exact calroie burn. plan you meals or entire day ahead. google a food guide or ask your GF nutritionist about healthy meal ideas. Add sodium to your tracking, you will be surprised how much salt can affect your weight and water retention. Tostitos are pretty high in salt. as everyone will say: eat more veggies, fruit and protiene are key to appetite control. and water, lots of water. Avoid caffeine in excess and dont drink or eat "diet" anything for 1 month and see if it helps by "diet" i mean diet coke or an y diet drink. or frozen weight control meals etc. some people actually gain weight when consuming fake sugars. google that too, there is plenty of university run studies regarding the consumption of artificial sweeterns and the effects ont he metabolism and body. but most importantly do some research, get some simple recipies, and try healty unprocessed foods, you will find what works by trial and error. Arm yourself with knowledge and all your hard work will pay off. nobodys perfect and treat foods have their place, but if your struggling or having a hard time asking questions and getting info is great, but what you do with it, thats what matters.

He always hits the nail on the head ... But one suggestion ... Get an HRM and use accurate calculations before you go eating everything MFP says you have ... They tend to grossly over estimate your exercise calories ! And if you begin strength training with weights ... You will initially see a gain ... But no worries, it will eventually turn cycle and you will notice a more leaner body. Don't rely on a scale to make you feel good ... If your all about numbers ... Start measuring inches !

Best of luck and stay focused ... You got this !
