This question is often asked by majority of the people, there are multiple answers to the question. Personally, I have been through this phase where I did not focus on my nutrition and the changes which were occurring to me. It is not felt at the very first because the process is internal and when it reaches its limit; you start to see the changes and they are terrible!
You must have had this conversation with your friends/family as to how can I stick to a particular nutrition plan and not get bored with it?? Well, human nature is designed in such a way that you cant stick to one activity throughout! Likewise, you have to bring changes in the food you eat and often add dishes which your taste buds love!
We all understand that it is difficult to be prompt or motivated towards something, distraction is always there! If we talk about our nutrition, we mess it up by eating in excess or the wrong combination of food available to us. What if you were asked to eat the food you like and still achieve the goals you have? Ask me how!
