Last week, I wrote about my resolve to become a better role model for my children when it comes to nutrition and exercise. Your response has been GREAT! So many of you have written in with the stories of your struggles with weight, your tips on weight loss, and the encouragement I need as I face the next step in my diet and exercise program.

Please keep reading the blog and watching "FOX & Friends." We’ll be mapping out a plan soon, and I want everyone to join me on this journey to health.

I’ve posted some of your e-mails below. Please keep writing, we can do this together!

"How right you are! It is so easy to know something but when it comes to doing it we postpone, procrastinate, make excuses, and easily forget. If we could make ourselves treat every meal as a prescription instead of a party, we would all be a lot better off. I have written more about this in my blog — www.familychowhall.com. My husband and I have been flirting with obesity for a while now and have both decided to put our knowledge where our dinner table is. For nearly six months, he has been packing lunch instead of eating restaurant food at the office — with the result of losing 30 lbs. Besides that, we have shifted from white breads and pastas to wheat, which helped our daughter go from a plus size to a regular. After our fifth child was born, I weighed 145 lbs. That doesn't sound like much but I am rather short. Right now, I weigh in at 135, and my goal is to shrink myself by 10 more pounds. I will be watching your blog for good exercise and nutrition tips. Thanks!" — Cheryl

"I am 51 and have been overweight for the majority of my life. I smoke cigars even though I know I shouldn’t (I am a nationally certified massage therapist) and don’t get much exercise. My son is in Iraq and I would like to surprise him when he gets back next November. I will be watching you on FNC and doing my part. Thank you." — Bruce (Centennial, CO)

"This Kansas nurse says: Good Luck Dr. Manny. You're obviously a Great Dad, too." — Anonymous

"I read your story about losing weight and being a good role model for nutrition and fitness and it inspired me. I too am a physician — I've been in practice for 10 years and have three kids aged 11, 9, and 7 — so I identify well with your quandary. I plan on joining you in your fitness bid in order to improve the ‘practice what you preach’ motif for us docs. I am going to the gym tomorrow! Way to go! I listen to you in my car on XM every morning as I go to my office." —Thomas MD

"Hallelujah! The incentive I needed! As a (barely) over 50 woman with high blood pressure and high cholesterol levels, and, I hate to admit, more than just a little overweight, I have been saying for months (years) now, that it's time to lose weight, eat right and exercise. Though my children are grown, I have always tried to set a good example for them. Looking in the mirror, it's obvious that I've slipped. Yeah, I love what a friend sent me about getting older: Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, chocolate in one hand, wine (martini) in the other, body thoroughly used up, totally worn out and screaming, 'WOO HOO! What a ride!' Why can't I have it both ways? What I'm saying is, I will join you in your journey and I look forward to the (WOO HOO) ride! — Susan (Richmond, VA)

"I watch you every morning. I work for the Navajo County Public Health Services in Arizona with two programs — Promoting Lifetime Activity for Youth and Walk Everyday Live Longer, Arizona. I understand fully what you are saying. What keeps me 'in line' is that I have met so many people through the programs and I need to practice what I preach. There are eyes watching me every step. Good luck!" — Anonymous

"I was very happy to read your blog. You are correct in that we, as parents, don't often set good examples for our children. We tell them not to smoke while we puff a pack a day. We tell them to go outside and get some exercise so we can have some peace and quiet in front of the TV. We tell them not to curse and have respect for their elders, while we slew profanities at the little old man in front of us who's driving too slow! It's a sad state of affairs. I admire that you will be proactive in ensuring that your kids stay healthy. I enjoy exercise but variety is the key. Eventually I get bored so I have to keep challenging myself and changing things up. As far as diet goes, I would recommend that you find the eating plan that works best for you. My friend at work does Weight Watchers and loves it! That doesn't work for me. I do South Beach and it's a lifestyle change, not a diet — at least for me it's not. I have to make a decision at every meal as to what I'm putting into my body. It was not easy at first, but I lost nine lbs in one month by not having cake every time it's put in front of me and making sure I got in some exercise about five days a week. Good luck to you! I look forward to hearing about your success!" — Mary
