I recently bought a food scale because I was having a hard time knowing what is considered a reasonable portion. I use it pretty much every day! I have found it very helpful because often times, we may think that we're eating the "right" amount of food but are usually over indulging. I use the scale to measure my nuts, fruits, rice/quinoa before eating.
Although most experts say to weigh yourself once a week, I weigh myself everyday. it keeps me on track and I can by tracking my food intake on Sparkpeople, I can analyze what works and what doesn't. How the food and calories affect my weight on a day to day basis.
Weigh and measure everything that you cook and eat! Most of us suffer from proportion distortion and underestimate what we eat.
When I weigh in for the week and the number on the scale isn't the one I wanted to see, I don't freak out over it, I don't beat myself up or decide to give up. Instead I take a good long look at myself in the mirror and find five things that I like about my body. Five things that I didn't like BEFORE I started eating and acting healthy and I remind myself that I'm happier than I've been in my life.
If I weigh 184 lbs I think to myself that I weigh 182 lbs. I tell myself over and over (in my head) that I weigh 182 lbs until I actually do weigh 182 lbs. Then I tell myself I weigh 180 lbs. etc. You get the idea. Sounds strange, but it works for me.
When I cook, I weigh the entire result in grams. I then divide by the number of servings. I enter that into SP as a new food. Say a serving is 100 gr. If I cut a slice & it is 80 or 125 grams, I change grams when I enter a food for that day, & it will recalculate nutrients accordingly.
Want to weigh less on weigh-in? First, eat at a reasonable time at night like 5-6PM, especially a low cal dinner like a piece of fish or meat & a small salad, & don't eat after that. Take an evening walk or do your exercising after dinner. In the morning, weigh yourself as soon as you get up, & naked.
