I am in the same boat, and have had 3 personal trainers, not to mention tried everything fad. My problem is self descipline, or the lack there of :-) Not to mention I am a professional baker.
In any case here is my advice-- you can go practical/healthy (which is slow/difficult, but sure to work) or try fads that may work temporarily (sometimes quickly)
Practical--Walking with body weights are great, but you have to keep at it and do it daily for at least an hour. Also having a workout buddy, someone to help hold you accountable/motivate you. In addition to these, have set meals for each day of the week.. write it down! This way you know what you will have, what you have had. No guessing, no room for changing. (boiled eggs, black coffee for breakfast, red grapefruit for snack, salad for lunch-fat free french dressing, protein bar for snack, broiled steak/fish for dinner with another salad- AS MUCH WATER AS YOU CAN STAND ALL DAY) My father lost 20lbs in 2 weeks on that diet.
Latest Fad version, you can try HCG drops I heard are the newest thing (Vitamin stores). There are a million fads I could recommend, however I dont know what your weakness/strengths are. 10 lbs is relatively easy to lose, just be careful with the starvation diets because you will get week at the end or after your goal is reached and gorge yourself. Thus putting back on the weight and maybe then some.
That's my 2 Cents worth M'am......
