Reducing Carbohydrate Intake Results in Weight Loss
Here is the abstract of a recent study looking at the results of restricted carbohydrates on health. Results indicate a 30 percent reduction in calories, an increase in protein intake, a reduction in trans fatty acid consumption, a loss of weight (mostly as fat), lower LDL cholesterol, and an overall reduction of cardiovascular disease risk.
I've been a fan of a reduced-carb lifestyle for years, and this is another study in a growing pile that supports that pointof view.

Background
Increasing evidence supports carbohydrate restricted diets (CRD) for weight loss and improvement in traditional markers for cardiovascular disease (CVD); less is known regarding emerging CVD risk factors. We previously reported that a weight loss intervention based on a CRD (% carbohydrate:fat:protein = 13:60:27) led to a mean weight loss of 7.5 kg and a 20% reduction of abdominal fat in 29 overweight men. This group showed reduction in plasma LDL-cholesterol and triglycerides and elevations in HDL-cholesterol as well as reductions in large and medium VLDL particles and increases in LDL particle size. In this study we report on the effect of this intervention with and without fiber supplementation on plasma homocysteine, lipoprotein (a) [Lp(a)], C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-alpha).
Methods
Twenty nine overweight men [body mass index (BMI) 25-35 kg/m2] aged 20-69 years consumed an ad libitum CRD (% carbohydrate:fat:protein = 13:60:27) including a standard multivitamin every other day for 12 wk. Subjects were matched by age and BMI and randomly assigned to consume 3 g/d of either a soluble fiber supplement (n = 14) or placebo (n =15).
Results
There were no group or interaction (fiber x time) main effects, but significant time effects were observed for several variables. Energy intake was spontaneously reduced (-30.5%). This was accompanied by an increase in protein intake (96.2 29.8g/d to 107.3 29.7 g/d) and methionine intake (2.25 0.7g/d, to 2.71 0.78 g/d; P < r =" .436," r =" .385,">Conclusions
A diet based on restricting carbohydrates leads to spontaneous caloric reduction and subsequent improvement in emerging markers of CVD in overweight/obese men who are otherwise healthy.

Thanks for the link!
Interesting but I not sure this adds a lot of weight to CRDs. It is a very small study of only 29 men who reduced their calories and lost weight.
The CVD risk markers they tested were very good though, but losing weight has benefits regardless of how you do it on a macronutrient level. Plus this put them into spilling ketones, this is not healthy and very people can ever stay on this restricted of a diet. Plus you have to eat a lot meat on this program. The meat we eat now days is factory farmed and Gods knows how many antibiotics and steroids are pumped into these scared animals. (Off topic but I personally feel this contributes to Americans being very aggressive and violent, but it is just a feeling, I have data to back this up)
There are many ways to eat healthy and manage weight, imo, and there many excellent studies have shown other combinations of macronutrients (that are low cal) to be effective at reducing CVD.
Do we as a society (in the US) eat too much refined carbs, YES. And some people are more carb sensitive than others, but healthy carbs in moderation can be well… healthy!
people focus on the issue of processing in meat as unhealthy while avoiding the simple truth that the majority of carbohydrates are processed. pastas, cereals and breads are manufactured products with shelf-life as a critical element. dietarily we are the victims of a media war designed to promote volumes of sales, not health. the levels of propaganda and disiformation in the media is staggering...........considering that the general public educated themselves via advertising and editorials and articles in popular publications designed to support those same ads, it`s not surprising that people are fat, malnourished and toxic.
