Started tracking calories again

I really need to lose weight by this October - when my sister is getting married. I am the matron of honor, and because my sister loves photography, I'll be in a lot of photos she is going to share. I want to lose about 25 pounds and the wedding is in roughly 25 weeks! I need to have a 500 calorie deficit every day! I started counting calories again today. I forgot how little I can eat to lose weight:( But it's good to make me think twice when I eat. For example, normally I would have 2 chicken patties which would be...

2 chicken patties: 400 calories
2 buns: 220 calories
Mayo: 100 calories (assuming I split 1 tablespoon over the two)
Total: 720 calories

What I did tonight:
1 chicken patty: 200 calories
1 bun: 110 calories
Light sour cream with seasoned salt: 40 calories
Total: 350 calories

Saved 370 calories

So, already I am making better decisions. I just have to be motivated to track.

Do high protein diets make you more thirsty?

I've noticed something a little odd the last two weekends: I have been really thirsty. At first I wondered if there was something different with the water in our city since there is a water cooler at work and I get most of my day's water from that source during the week. Or I thought maybe it's just more humid at work. But then I happened to think during the week when I'm working I go for simple carbs and don't eat as much protein. My plan a couple weeks ago was to start a high protein diet, but the only days I've been able to stick to it were on the weekends because I have more time to prepare my food and I'm not reaching for carbs just to "get through the day". So I looked it up and sure enough, a side effect of a high protein diet is dehydration. Researchers from University of Connecticut tested the hydration levels of athletes on diets containing low, medium, and high levels of protein. It was reported in an article by Web MD, that "although all the athletes drank about the same amount of fluids, their hydration level went down significantly as their protein intake went up."

I researched this a bit more and found several articles saying high protein diets, especially from animal sources, may cause kidney damage. However, most of the research was inconclusive. So I guess for now, I just need to drink extra water, maybe try to find protein sources not from animals, and proceed with caution.
