Avoid eating just before your bedtime, study recommends
Conclusions Previous research suggests we may be better off consuming more of our calories earlier on in the day, when we have a full, active day ahead of us to use up the energy. It's also been observed that people who consume large calorific meals late in the evening can have a higher body weight. In a sense, the results of this study seem plausible and don't really say anything different from what's already been observed. But as this is a cross-sectional study, it can't really prove very much. The study involved a small, select sample of US university students. Their results can't be applied to everyone, as they have di...

7 Steps To Round-The-Clock Energy

It should—according to science, we’re hardwired for those post-lunch energy dips, which stem from a drop in our core body temperature that naturally happens in the afternoon. The temperature drop then triggers the release of the sleep hormone melatonin. It’s a normal part of our body’s internal clock, known as our circadian rhythm.

10 Habits That Will Dramatically Improve Your Life
In Hans Christian Andersen’s fable The Red Shoes, a young girl longs for a pair of pretty red shoes. She ultimately tricks the blind woman who cares for her into buying her a pair. Her love for the red shoes causes her to give them priority over the more important things in her life, and, as often happens in fables, karma is not on her side. The shoes become firmly stuck to her feet and force her to dance non-stop, to the point where she almost dies from exhaustion and starvation. We can scoff at the little girl’s foolishness, but, in real life, we often do the same thing—we chase after the things that we...
