One of the most often overlooked things in a person’s life is what they put in their body. It seems simple, but it can be last place a person will look into order to improve their lives. And it all starts with water. If you are not hydrated, your body and mind will have a difficult time operating.
It is important to listen to your body shortly after eating. That is the best indicator a person can get. Are you feeling lazy and finding it hard to focus after lunch? It may well be that what you ate had a negative effect on your body and mind.
Although everyone is different, I have found that the less carbs I eat at lunch, the better I feel. For some reason I tend to perform optimally after eating sushi. So I try and eat sushi or even some sort of chicken or beef teriyaki for lunch when I know I still have a lot of important work to do in the afternoon.
So stay mindful of what you put in your body and the effect that it has on you. You may even find it helpful to keep a food journal. That is the easiest way to track what you are eating and whether the food is having a positive or negative impact.
