Your emotional state has a lot to do with your weight. If you are happy — really happy, not just on-the-surface, pretend happy — you are more likely to be leaner.As people lose weight, their mood improves.As their mood improves they cut their risk in half for everything from heart disease to diabetes, because they are more motivated to take better care of themselves. Happiness lowers our stress hormones, such as cortisol. Lower stress means we sleep better, think more clearly and have more energy, which are all factors that help with weight loss and happiness.Additionally, people with sunny outlooks are more likely to choose healthy foods which in turn fuels their good mood.They are less likely to get sick, they recover quickly if they do get sick and they live longer than people who are either depressed and/or overweight.It works in reverse too. People who choose foods known to improve their mood find it easier to lose weight, cope with stress and sleep better.However, when people are overweight, they may feel sluggish, unattractive, tired and depressed.They turn to unhealthy foods to soothe the dark clouds, which adds more weight and stress and disrupts their sleep and mood even further.Studies have shown that poor sleep habits also increase the risk for being overweight by up to 70 per cent.The foods we eat can do much more than nourish the body.
