Starting my weight loss

I can't tell you how many times I've started a fitness journal. I write for a few days and then I completely stop thinking I'll catch up writing another day. Well I figured that since I am always at a computer, that I would keep a blog of my daily food, exercises and feelings for my weight loss. Some tips that I have learned from my sister are: to eat a protein and a carb at every meal, drink lots of water, stay away from sugar, lifting weights are just as important as cardio and to stay under your limit for calories.
