Whenever I buy a 'snackable' food (carrots, crisps, pretzels, cookies, ect) I immediately repackage it into serving size baggies with the calories written directly on the package. That way everytime I reach for a snack I'm reminded of exactly what I'm eating!
Encourage serving sizes, particularly with treats, by using cute, elegant, or personalized serving sized dessert dishes.
When I am cooking if I cook more servings than I need to eat it is just too tempting for me and I end up eating more than I should, even if I try to separate it out for the week and put it in the refridgerator, so instead I just cook one serving (Unless of course I am cooking for others as well.) This removes the temptation of eating extra food.
I always take a container to restaurants. The portion sizes they serve are huge. I immediately take half of the meal and put it into my plastic container as a doggy bag....out of sight, out of mind. If you wait until the end to ask for a doggy bag, you've probably eaten too much already. It's a great way to have lunch or another dinner for the next day.
When I bring something home from the store that has more than one serving to a box (snacks/cereals/etc.), I get out my zipper bags & measuring cups and pre-measure individual servings into bags. I keep the bags in the original box, so they're easy to grab, use AND stick to your portion control!
I hate water, but I love my family. I've got a 32 oz. Breast Cancer Awareness mug that I use everyday. I have an aunt who is in remission, and every day I tell myself to drink 64 oz. of water to stay healthy. 32 oz I drink for me, and 32oz is for her. That's my eight cups of water a day, cheers!
Sometimes it's hard for me to make sure I'm getting enough fruit & vegetable servings each day. I found that beverages such as low-sodium V8 juice or V-8 Fusion are a good way to increase my intake. Watch the calories, though, and use this as a supplement rather than your sole "produce" option!
