Hi KathyKat,
I completely relate. I think it is so important to follow a great eating regimen--like Kind Diet Superhero or Vegan. I had a personal trainer who told me that if you eat too little your body will freak out and store fat--so you need the good kinds of fats. And, if you eat too much, well, that is obvious, right? My trainer also told me it is important to do cardio at least 2-3 times a week at a fat burning level. This means that you would do a special calculation to find at what number you need to get your heart rate up enough so that you are burning fat. I believe that there are probably many websites to take your through this calculation and some cardio machines have this information on them.
Now, as for spot areas, well, there is a way to spot treat them. My trainer suggested that I see a Chiropractor that practices kinesiology. This kind of chiropractor can help you straighten your spine and make your workouts more efficient, and can help your posture which will make your body look longer and leaner and more balanced. Also, you can do certain exercises that target your thighs. My favorite ones are from Jillian Michael's video, "No More Trouble Zones". These exercises seriously tone and firm those areas. Another thing is exfoliate your skin. Using coffee grinds will diminish cellulite and firm up trouble areas, at least temporarily. Also, there are many citrus oils and scrubs that will help.
So, there are many things you can do to eliminate this area that is troublesome for you. My trainer also made a fabulous suggestion of visualizing my body the way I envision perfection while taking steps towards this goal, and to appreciate all the assets I have.
I hope these suggestions will help.
Good Luck!
