Drinking a casein shake just before overnight sleep increases gains in muscle mass and strength in response to resistance exercise. But to date, no study has directly addressed whether this effect is due to increased total protein intake only, or if a bedtime beverage is better. According to a review published in Frontiers in Nutrition, existing findings nevertheless suggest that overnight sleep is a unique nutritional window for boosting muscle gains -- while late-night protein calories needn't increase body fat. Casein point: Snijders' seminal study "Several one-night studies have shown that pre-sleep protein intake increases muscle protein synthesis during overnight sleep in young adults" says lead author Dr. Tim Snijders, Assistant Professor at Maastricht University. "These have fueled the idea that over a longer period, a pre-sleep protein supplement can maximize the strength and muscle mass gains during regular resistance exercise training." Snijders&…

In a new study, researchers at Uppsala University now demonstrate that one night of sleep loss has a tissue-specific impact on the regulation of gene expression and metabolism in humans. This may explain how shift work and chronic sleep loss impairs our metabolism and adversely affects our body composition. The study is published in the scientific journal Science Advances. Epidemiological studies have shown that the risk for obesity and type 2 diabetes is elevated in those who suffer from chronic sleep loss or who carry out shift work. Other studies have shown an association between disrupted sleep and adverse weight gain, in which fat accumulation is increased at the same time as the muscle mass is reduced -- a combination that in and of itself has been associated with numerous adverse health consequences. Researchers from Uppsala and other groups have in earlier studies shown that metabolic functions that are regulated by e.g. skeletal muscle and adipose tissue are adversely affect…

Physical inactivity is a common factor in lifestyle diseases -- and one that is often linked to the excessive consumption of fatty and/or sugary foods. The opposite scenario of excessive physical activity at the expense of caloric intake can also be harmful, as cases of anorexia nervosa illustrate. These data therefore point to the crucial need to research the neurobiological processes that control the respective motivations for exercise and food intake. A study by Inserm and CNRS researchers published on March 7, 2019 in JCI Insight reveals that the cannabinoid type 1 (CB1) receptors play an essential role in the choice between running and eating chocolatey food. The authors of this paper had previously reported that the cannabinoid type-1 (CB1) receptors, present on several types of neurons, play a key role in performance during physical activity in mice. A conclusion based on the performances achieved by animals with free access to an exercise wheel -- a model in which it was not …

Elite performers had an 80 percent reduction in mortality risk when compared to lower performers.
Cleveland Clinic researchers have found that better cardiorespiratory fitness leads to longer life, with no limit to the benefit of aerobic fitness. Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing at Cleveland Clinic between Jan. 1, 1991, and Dec. 31, 2014, to measure all-cause mortality relating to the benefits of exercise and fitness. The paper was published today in the Journal of the American Medical Association Network Open. The study found that increased cardiorespiratory fitness was directly associated with reduced long-term mortality, with no limit on the positive effects of aerobic fitness. Extreme aerobic fitness was associated with the greatest benefit, particularly in older patients (70 and older) and in those with hypertension. "Aerobic fitness is something that most patients can control. And we found in our study there is n…

You Need to Make a Big Decision...For more click http://bit.ly/2XN6e9I
I'm not sure if you've ever felt the same way, but I used to believe there was a "secret trick" to losing weight. One week, I would try some special "fat-burning" exercises, and then the next week, I'd try taking a weird new supplement. I constantly struggled, and I hated every minute of it. I felt like I was trying so hard, and even worse, I thought my failure to shed pounds was due to my lack of mental determination. But then I made a decision... I decided that I was going to respect and heal my body. I was going to stop looking for the "secret" tip or trick, and I was going to find a natural way to lose weight and feel great. And - as it turns out - being slim and lean is part of our natural biology. You simply need to activate your body's built-in mechanisms for burning fat. When I discovered how to do this, I was hooked... ...My excess fat (especially around my belly…
