Yes, it is a series of ups and downs. But only you can make it go one way or the other. I have been struggling with my weight for years, like most people here. We just need to ask ourselves "what do I want more?". The answer for me is easy. I want to be healthy and fit. Nothing is easy, but we can do anything we set our minds to. Every day, month, year we put this off, only makes it harder on ourselves. We are not getting any younger, as you grow older, the more difficult it will be. We need to decide what we want and commit to doing it. The answer is in the foods we eat. If you get the right nutrients, your body will stay fuller longer. I eat whole grains, lean meat, fruit, veggies, and beans. I season my food with herbs and spices. I do not feel hungry, nor do I go off plan.
Sorry, your day isn't going well. I hope you can pick yourself up and just move forward. You can do this!
