NEW YORK (Reuters Health) - Foods with a low-glycemic index, which are digested relatively slowly and cause smaller increases in blood sugar, may protect the heart and blood vessels better than low-fat fare, according to the findings of a small study.
Researchers in Boston found that when obese people consumed as many carbohydrates with a low-glycemic index as they wanted, they lost just as much weight in 12 months as people who stuck with a conventional, calorie-restricted low-fat diet.
Carbohydrates with a low-glycemic index include foods such as nonstarchy vegetables, fruit, legumes, nuts and diary products, according to the report in the American Journal of Clinical Nutrition.
Dieters who watched their glycemic indices also experienced a larger decrease in fatty substances in the blood linked to heart disease and had a drop in levels of a protein that interferes with the body's ability to break down blood clots. In contrast, low-fat dieters had an increase in levels of the same protein, which may put them at higher risk of heart attack.
"Reducing (glycemic index) may be more effective than cutting back on fat over the long-term, both for weight loss and also for reducing risk of heart disease," study author Dr. David S. Ludwig told Reuters Health.
"Based on our results, and several dozen other clinical trials and epidemiological studies, I would recommend" eating foods with a low-glycemic index, added Ludwig, who is based at Children's Hospital.
The glycemic index measures how efficiently the body can metabolize carbohydrates. It ranks carbohydrates by how much a person's blood sugar rises immediately after eating, and tends to favor high-fiber foods that take longer to digest.
Ludwig and his team asked 23 obese young adults to follow either a low-fat diet or a diet in which they ate low-glycemic index foods for one year. As part of the low-glycemic index diet, people could eat as much as they wanted of foods with a low index, and got roughly 45 to 50 percent of calories from carbohydrates, and 30 to 35 percent from fat.
Low-fat dieters cut their daily intake by 250 to 500 calories, limited fat to less than 30 percent of their total calories, and got between 55 and 60 percent of calories from carbohydrates.
Ludwig noted that even though low-glycemic index dieters had no calorie limits, they likely didn't overeat because they felt less hunger after eating foods that take longer to digest.
"Numerous previous studies by our group and by others have shown that individuals feel less hunger and greater (sense of fullness) after low-glycemic index compared to high-glycemic index meals," he added.

That's when life sucks on low-glycemic/low carb.
That said, a sugar-free chocolate fondue (with Splenda) and a shot of Bailey's is really nice for dipping strawberries...
Hmm, diary products. I don't know why this is such a novel idea, certainly nothing to wax poetic about.
Low fat milk is probably the most harmful product on your grocer's shelves.
Strawberries and Blueberries can be eaten in relatively large quantities.
Your Welcome and your thread on PCOS is a hot button for my wife. Her female problems went away after beginning Atkins, heartburn too.
Eliminate all manufactured food and boxed or canned food and potatoes and rice. With an active lifestyle the weight loss will start eventually.
My other real weakness is potatoes. Ain't nothing I can do about that. They are high carb/high glycemic. I don't suppose one every now and then would hurt that much.
That is the book my wife brought home - 8 years ago. It works.
CONGRATULATIONS!!!
bttt
Many thanks, and please add me to your ping list.
Thanks, and yes she is planning to breastfeed. We've heard that works as a great weight loss aid, but time will tell.
I'm glad the wait is about done.
Thank you and will do ...
see post number sixty two...
Our experience is just one data point. But for us it was black and white: she was in ketosis, mild, week after week, and lost 2'lbs of fat week after week. The bottom line was keeping track of the carbs and making sure overall calorie intake dipped under the keto trigger point. It was hard on her for a bit up front. The first few months cals were greater than 1000 a day, but eventually had to be cut to 800 a day. It was pretty much hell for awhile, but she simply learned to deal w/ the hunger and religiously avoid the carbs
Plus, she drank at least a gallon of water a day. It worked. Of course, 9 months later and a baby later, there is some ground to recover. But the trade is more than even...

Given you know what PCOS is, then you are likely aware of the thrall so many women who are afflicted by it are in by the medical establishment.
True, the doctors will say, 'lose weight'. They won't, ever, say use ketosis to be your helper. If we didn't have that, plus the ketostix, I don't think we could have done it. She lost 70 pounds before she got pregnant; but every morning leading up to that the ketostix was checked: light purple, good. Light Tan ... not good.. it was utterly effective as a feedback tool.
So yep, PCOS is a hot button for us too...
Aspartame has been linked to brain tumors and other potentially lethal medical conditions. Soft drink makers are catching on as people are leaving Diet Coke and other diet soft drinks on orders from enlightened health care advisers. Phenylalanine added to most Coke products is far worse than caffeine for keeping everyone up and "reving up your body" - harmful for kids too, giving symptoms of ADD and hyperactivity.
