Change can be hard. Changing your diet can be doubly tough and America’s favorite foods don’t exactly help matters. Dr. Fuhrman explains in Eat For Health
Modern foods are designed to seduce your taste buds. You have been manipulated by profit motivated food manufacturers. We all have. The artificially concentrated flavors that the processed food industry uses to stimulate the brain’s pleasure center are designed to increase and retain sales. Tragically, the result is that they lead people’s taste buds astray. Artificial, intense flavors cause us to enjoy natural flavors less. Our taste buds become desensitized, and the more we succumb to the heightened, artificial flavors, the less appealing natural, whole foods become.
Now, Shari Roan of The Los Angeles Times
asks the question, “Why it's hard to maintain weight loss?
” Here’s an excerpt:
"There is a big shift toward understanding long-term weight maintenance," says Paul MacLean, associate professor of medicine at the University of Colorado, Denver. "We have a huge number of diet books and diet programs, and if you do them, you can lose weight. The big problem is keeping it off. The recent estimates are that 5% to 10% of people are successful at keeping weight off on a long-term basis."
But before you throw up your hands and reach for the Twinkies, consider this: Scientists think the truth will set us free -- that understanding the stubborn biological processes at work will lead to ways to fight back and outsmart them.
Exercise, it's known, buffers the post-diet body against regaining weight, in ways that researchers are just starting to comprehend. Certain foods, scientists believe, may help stave off weight regain too. And medications now in development target some of the biochemistry thought to be linked to packing the pounds back on…
…Appetite hormones change too. The hormone leptin, for example, is a major appetite regulator -- it tells the body to stop eating and store fat after meals. Some people may be genetically prone to having lower leptin levels, making them more prone to obesity. But studies also show that, after a weight loss, leptin levels are lower than what they used to be. That means appetite is less easily quelled. It's like a car that has suddenly lost its brakes.
Another hormone, ghrelin, stimulates food intake -- levels in the brain fall lower after a meal. However, after a weight loss, ghrelin levels in the blood generally increase, and the fall-off after mealtimes isn't as marked.
"You lose 10% of your body weight. All of a sudden all these systems kick in to try to keep you from losing weight," says Dr. Ken Fujioka, director of nutrition and metabolic research at the Scripps Clinic in San Diego. "People are mad at themselves or depressed after they regain the weight. But I explain: It's not you. Biology has kicked in now. . . . You are hungry all the time. You think about food all the time."
This is all well and good, but staying determined and keeping your eyes on the prize is a great way to buck to the trend. More from Dr. Fuhrman:
It is not easy to develop new habits, and there is no such thing as a quick shortcut to developing new skills and expertise. When you do something over and over, it creates a pathway in the brain that makes it easier and more comfortable to repeat again. That is one reason why it is so hard to change bad habits. However, if you are motivated to persevere and keep trying, the change becomes considerably easier. The more you make healthful meals and the more days you link together eating healthful foods, the more your brain will naturally prefer to eat that way. Of course, feeling better and losing weight is a great motivator, but through this process, your taste for a different way of eating can be established. It has been shown that a new food needs to be eaten about 15 times for it to become a preferred food. Keep in mind that the more days you eat healthfully, the more you will lose your addiction to unhealthful, stimulating substances, and, with time, you will look forward to, and prefer, a healthy diet. Don’t give up. The only failure is to stop trying.
I’m not an expert, but I think eating and living healthfully gets easier the longer you do it. For me, its as if my instincts changed—know what I mean?
