Comer pasteles en el desayuno podría ayudar a bajar de peso. Un estudio liderado por Daniela Jakubowicz de la Universidad de Tel Aviv y recogido por The New York Times, demostró que una dieta baja en calorías, pero que incluye postre o pasteles en el desayuno, es efectiva para bajar de peso. Para llegar a esta conclusión, se escogieron al azar a 144 personas obesas, de entre 20 y 65 años, a quienes se sometió a una dieta baja en carbohidratos y de 1.400 calorías diarias para las mujeres y 1.600 para los hombres. Eso sí, a un grupo de individuos se les incluyó una selección de galletas, chocolate, torta o helado.
A lo largo del tratamiento, se evaluó a los participantes periódicamente, midiendo los niveles sanguíneos de insulina, glucosa, lípidos y grelina, hormona que estimula el apetito. Transcurrido un periodo de 4 meses, se determinó que la pérdida de peso promedio en ambos grupo era la misma- cerca de 14,5 kilos. Can Eating Breakfast Make You Fat? My early morning trek to the gym takes me past a Dunkin Donut shop and a long line of sleepy commuters waiting to buy breakfast. The shelves of this franchise coffee shop are stocked with varieties of doughnuts, muffins, bagels and breakfast sandwiches of an egg with cheese and fatty meat. As I continue down the block, people are standing in long lines at MacDonald’s so they can eat a hot meal of scrambled egg and hashbrowned potatoes, or cream saturated oatmeal, pancakes and syrup, or egg, ham and cheese breakfast sandwiches, along with their coffee.
Two blocks away, an up-scale neighborhood bakery-coffee shop sells fatty, chocolate filled croissants or butter laden, gigantic cranberry scones and gourmet coffee to people working at a nearby hospital. And at a convenience store across the street from my gym, high school students filter in to buy a bottle of soda and bag of Doritos to eat on the way to school. Of course the answer is that it depends on what is eaten. Eat Early to Stay Healthy and Sleep Better. Is there a good time of day to eat anything you like? Anything at all? Possibly, yes. The answer is based upon how our body is influenced by our daily rhythms of eating and sleeping . For example, numerous studies have shown that shiftwork and the odd patterns of sleeping and waking that this lifestyle involves, has many negative health consequences, including obesity , diabetes and metabolic syndrome as well as insomnia .
Very little is known about how alterations in the rhythms of eating and sleeping affect overall health. Scientists at the Salk Institute for Biological Studies in California recently published a study in the journal that investigated one important aspect of this problem. Their question: which is more important—what you eat or when you eat? Mice were given free access to either a standard, nutritionally-balanced chow or a chow that was high (61% of calories) in fat. Now for the good news! © Gary L. 'Junk food' moms have 'junk food' babies. A new research report published online in The FASEB Journal suggests that pregnant mothers who eat high sugar and high fat diets have babies who are likely to become junk food junkies themselves. According to the report, which used rats, this happens because the high fat and high sugar diet leads to changes in the fetal brain's reward pathway, altering food preferences.
Not only does this offer insight into the ever-increasing rate of human obesity, but it may also explain why some people easily resist fatty and sugary foods, while others seem hopelessly addicted. "These results will help us to better help women about diet during pregnancy and breastfeeding for giving their infants the best start in life," said Beverly Muhlhausler, Ph.D., co-author of the study from the FOODplus Research Centre in the School of Agriculture Food and Wine at the University of Adelaide in Adelaide, Australia.
What Caffeine Really Does to Your Brain. I recently stopped drinking coffee. Yeah, I know, why would anybody do that? For me it was a combination of health-related reasons, and overall I can say I’m happy I did. If you had asked me a few days after I kicked it, though, I would have told you it was one of the dumbest things I ever even thought of doing — that is, if my head stopped pounding long enough to answer you in a complete sentence. This radical life adjustment made me curious about caffeine and its effects on the brain , so I did some research. The most surprising thing I found was that caffeine doesn’t really jack up the volume in our brain the way most of us think it does — the story about how our favorite drug works isn't nearly so straightforward. First, what caffeine does not do. Caffeine does not, by itself, make you a super productive, super fast, super talky jitter machine.
What caffeine does do is one heck of an impersonation. In other words, it’s not the caffeine that’s doing the stimulating. Lose weight: healthy diet and weight loss information from NutritionData.com. Nutrition: How Much Protein Do You Need? Carmen Castanada Sceppa, M.D, Ph.D., is a scientist working at the Jean Mayer USDA/Human Nutrition Research Center on Aging at Tufts University School of Medicine. Carmen's research emphasizes protein nutrition and physiological function of healthy older individuals and those with chronic illnesses. How does the average intake in the United States measure up against the Recommended Dietary Allowance (RDA) for protein? The typical American diet provides plenty of protein — more than the RDA in most instances. The RDA represents the minimum amount of protein needed to fulfill protein needs in 97.5% of the population. This value is equal to 0.8 g of protein per kg body weight per day. Muscles are built from protein.
Carmen, we hear a lot in the media about balancing different types of proteins. Plant protein sources, although good for certain essential amino acids, do not always offer all nine essential amino acids in a single given food. . (49) Comments have been made ResponsetoMZMAKZ Janice.
