I try running, stair climbing and stretching every day and I try not to eat to feel full up. I don’t know if this is a stupid idea, but I’m sure dieting involves feeling moderately hungry, which is what I do now.
Sometimes, after a long hard workday I feel so hungry I eat a lot for dinner, meaning I don’t have to have breakfast before I start working out. I don’t know if this is also a stupid idea. Do you have a small breakfast before starting your work out in the morning before going to work?
A variation of this involves eating only whole grains at night before going to sleep because sometimes that’s the only thing at hand.
Should I change anything?
This is too vague to give an in depth answer as we don’t know your ultimate goals or your diet as a whole but not eating before working out isnt bad. Some diets such as intermittent fasting involves fasted work outs.
Changing both your diet and work out habits can be hard, especially if you do it all at once which can become demoralising and hard to maintain over the long term.
I encourage you to research different approaches towards your ultimate goal and make smaller changes over time with a view of changing your outlook on food and exercise for the long term and making it stick.
