Hi! Well my friend is having great success on this, like you she did not have much weight to lose, under 10 pounds but she's just about lost it!
Like you she also has NO time.
She is a professional therapist who works in people's homes so is in the go all day. Basically you eat little snacks throughout the day that are easy to fit into your breaks.
Stuff like seeds, nuts, chocolate (???) and fruit. So, pretty easy and portable. She just packs a little bag of stuff in the morning and that's it!
I've had some success just counting calories but my friend looks so great and the food on this diet and the food really appeals to me (I love avocados, sunflower seeds, olive oil and other "good" fats!)
TO DO LIST: Lose one pound. Keep it off.
