A new study suggests that substituting whole grains for refined grains in the diet increases calorie loss by reducing calories retained during digestion and speeding up metabolism. This research is published in tandem with a study on the effect of whole grains on gut microbiota. Both studies are published in the American Journal of Clinical Nutrition.
Epidemiology studies have suggested health benefits of whole grains and high dietary fiber intake, including for glycemic control and insulin sensitivity. There has been controversy, however, about whether whole grains and fiber are beneficial for weight regulation, partially because there hasn’t been data from controlled metabolic studies. This new study provided food to participants for eight weeks and may help explain how whole grain consumption is beneficial for weight management.
Consumption of fast foods and processed foods took another hit today according to a couple of studies from Tufts.
In a clinical trial, adults who consumed a diet rich in whole grains rather than refined grains had modest improvements in healthy gut microbiota and certain immune responses. The research was conducted in tandem with a study that looked at the effects of a whole-grain diet on energy metabolism. Both studies are published online today in the American Journal of Clinical Nutrition.
Whole grain consumption has been associated with reduced risk of heart disease, type 2 diabetes, and some cancers. Researchers have speculated that whole grains lessen risk for diseases through reducing inflammation, but studies comparing the effects of whole grains versus refined grains consumption have not controlled the diets of study participants and have not evaluated cell-mediated immune responses to uncover the impact of whole grains on immune and inflammatory responses.
The research team analyzed the results from an eight-week randomized, controlled trial with 81 participants to see what effect a diet rich in whole grains, as opposed to a diet rich in refined grains, would have on immune and inflammatory responses, gut microbiota, and stool frequency in healthy adults. For the first two weeks, participants consumed the same weight-maintaining Western-style diet rich in refined grains. For the next six weeks, 40 of those participants stayed on that diet, while 41 participants consumed a diet rich in whole grains. Continue reading
Research has shown that the traditional Mediterranean diet reduces the risk of heart disease. In fact, an analysis of more than 1.5 million healthy adults demonstrated that following a Mediterranean diet was associated with a reduced risk of death from heart disease and cancer, as well as a reduced incidence of Parkinson’s and Alzheimer’s diseases.

The heart-healthy Mediterranean is a healthy eating plan based on typical foods and recipes of Mediterranean-style cooking. Here’s how to adopt the Mediterranean diet.
If you’re looking for a heart-healthy eating plan, the Mediterranean diet might be right for you. The Mediterranean diet incorporates the basics of healthy eating — plus a splash of flavorful olive oil and perhaps even a glass of red wine — among other components characterizing the traditional cooking style of countries bordering the Mediterranean Sea.
Most healthy diets include fruits, vegetables, fish and whole grains, and limit unhealthy fats. While these parts of a healthy diet remain tried-and-true, subtle variations or differences in proportions of certain foods may make a difference in your risk of heart disease.

I am a big fan of Drs. Oz and Roizon, the authors of the YOU books, YOU on a Diet, YOU Staying Young, etc. I have read them and recommend them. I saw an ad that described them as “Serious science presented to you in a highly digestible way.” I think that is exactly right.
YOU on a Diet was the first Dr. Oz Book I ever read
On the premise that Americans find filling out their tax forms easier than following dietary info, Dr. Oz offered several simple guidelines for losing weight and reducing belly fat.
1. Don’t eat foods with added sugars or added syrups. When possible, avoid artificial sweeteners, too. They lie to your appetite control system and can lead to weight gain.
2. Choose 100% whole grains. Your guts, immune system, and heart will thank you.
3. Eat slowly so you can tell when you’re full. Then stop.
4. Eat often (4 to 6 times a day) to prevent hunger. Hunger leads to overeating, which is bad for the heart and triggers weight gain.
5. Get nine servings of fruits and veggies a day. Think of it as nine fistfuls of goodness.
6. Opt for lean protein. Good sources include chicken (no skin), fish, beans, and whole grains. Spare your heart and brain the damage that too much saturated fat causes.
7. Get a blood test to check your levels of vitamin D and B12. Take supplements if you’re deficient.
I think these are a good supplement to my How to Lose Weight – And Keep it Off page.
