Recently my mother lost a significant amount of weight and really didn't put THAT much effort in. If you asked her she probably wouldn't even know what to tell you. She has gone through some big life changes but from my careful observation (which is easy to do when you are roommates) these are two of her tried and true rules that make a huge difference.
1. At restaurants she puts half of her entree in a to-go box before she even starts eating.
2. She drinks warm lemon water religiously.
My mother also does this at restaurants. I can just hear her, "I'll have a water, with lemon, no ice." Again your server will probably roll their eyes but who cares. Lemon water not only helps clean the toxins from your cells, aids digestion but the pectin fiber that lemons possess also helps bodies fight hunger and cravings.
For those of you who might be looking to loose a few pounds I hope you find this helpful. You are beautiful and your body deserves to be treated with respect so work on finding a way to do this, if loosing weights is a result of this new version of respect - well then wonderful.
