I keep a small journal style notebook in my kitchen. When I fix a quick, easy meal I jot down the ingredients and instructions in the notebook. When I am in a hurry and can't decide what to cook, I can just flip through the notebook to remind myself of quick easy meals
I like to be able to make a meal in less than 10 minutes... so to speed things up I store all my salad makins (lettuce, green onion, tomato, nuts, etc) in a bin in the refrigerator crisper. When I make a salad, I just take out the bin and it saves a lot of time. I use the same method for sandwiches
I cook up several pounds of ground beef and keep a supply in the freezer. After cooking, freeze on a cookie sheet so you don't get a big frozen lump LOL and then transfer to a freezer bag or container. Having pre-cooked ground beef on hand makes spagetti, tacos, etc a snap to make!
I keep those pesky plastic bags in my reusable grocery tote... then when I go to the grocery store I always have them with me to toss into their recycling bin.
I buy a big stack of paper coffee filters at the $1 store and use them for microwave cooking. They work great as dish covers and also as coasters for microwaving small foods like rolls or muffins when you don't want to get a plate dirty. Way cheaper than using paper towels!
I used to have trouble staying on track and came to realize that it typically was when I didn't have the right foods in the house. Make sure you always stay well stocked with healthy nutritious foods that are easy to prepare. I keep a list of "essentials" and have it with me when I goto the store.
I use the plastic tops from margarine tubs and the like as coasters for items in my pantry and bathroom. The plastic coasters will keep drips from syrup bottles, bathroom cleaners, etc from staining the shelf and they are easy to rinse off!
Skinny people eat in moderation, exercise and are active. It isn't about depriving yourself of every pleasure in life... live your life like a skinny person and you will soon be one!
I keep a pocket calendar in the bathroom and record my weight every week and then jot a monthly total at the bottom of the page. It keeps me focused and I can see at a glance the progress I have made. I lost 3-4 pounds a month, but was motivated by seeing how much progress I made in a year!
