I am fascinated by the scales ! and look at them as a positive learning experience instead of something to be discouraged about.
When I weigh myself during the day, I note what I've eaten that has made me put on those lbs, then if they're gone the next a.m, no worries.
I have a problem with grains and if I eat them, I gain and the lbs can stay but if I eat tons of veggies and good foods and I gain in one day, it's gone the next morning. So I learn what hinders me and what gets used.
Don't look at them as the enemy rather use them as a tool to learn how your body reacts to what foods you consume.
and if you still are discouraged, then stop. Use your clothes as a guide to how you're doing.
If it is a plant, eat it, if it comes from a plant, don't!
