Let's face it, there is no "secret" to losing weight. It's simple -- bank less calories than you spend and the weight will come off. You don't need to take pills or buy into the latest diet craze. Common sense is all you need.

I spoke with my oncologist the other day about my own weight loss -- I have lost nearly 14 pounds since the beginning of May, thanks to a no-sweets, low-sugar, low-fat, water-only diet with an emphasis on high fruit and veggie intake. Now this is no temporary diet. This is for life. My goal was never to lose a bunch of weight and then go back to eating junk -- I just wanted to shed a few cancer treatment-induced pounds while embracing a brand new healthy lifestyle.

My doctor was proud of my progress and shared his too -- he's lost eight pounds by cutting 500 calories from his diet each day. It sounds like a lot but this can be accomplished by cutting down on portions, giving up soda, and ditching high-calorie snacks. Observing the physical changes we both had made, he announced to the medical students in the room with us at the time that weight loss is not so hard -- well, maybe mentally hard, but not physically. He talked with his students about how to advise overweight patients -- surely a large percentage of people they see -- and reminded them of this formula: take in less than you spend. They nodded in agreement. And we moved on to other topics. There really was nothing more to say. Simple, I tell you. Give it a try.

When it comes to portion control and weight gain, you would think that 85 food and nutritionist experts would know better than to serve themselves heaping bowls of ice cream. One of the common sense theories that links the continuing increase of weight gain in this country has been the tendency of Americans to super-size meals.

Cornell University researchers held an ice cream social and invited 85 food and nutritionist experts to the serve yourself function. The guests were given a choice of bowl and spoon size. The ones that chose the bigger bowls and bigger spoons served themselves over 50 percent more ice cream than the guests who chose the smaller bowls and spoons.

Based on the experiment, the researchers recommend anyone interested in losing weight to downsize their plates, bowls, forks and spoons. It might be as simple as that -- smaller portions on smaller plates looks like more food. Smaller portions on larger plates looks like deprivation and not exactly a motivator to eating less. Perception is everything.

When my treatment for breast cancer was just around the corner, I asked a nurse about a dietitian on staff who I might talk to -- or a nutritionist or anyone who could help me wrap my head around eating right and staying healthy and maintaining my weight during treatment. I was told that I didn't need to talk to anyone -- that I would likely not lose any weight and would be fine. I was aware at the time that a referral to a dietitian often occurs with weight loss associated with treatment -- but it seemed that a referral for merely staying on track was just as important. Yet this seemed not to be an issue.  And I never was referred to anyone. So I found someone on my own -- and independent nutritionist who came to my house just after my first dose of chemotherapy, on a day when I felt nauseated and foggy and sick. It was a perfect time to talk to someone about how to eat during this difficult time, and the wisdom that was shared with me is as fresh in my mind today as it was 18 months ago -- when I sat at my dining room table with my mom and a young woman who knew exactly what I wanted to know.
