If you have a bowl of ice cream and feel, "This is bad food for me. I am weak and have no will power to not eat this...", and continue to eat, you have just made yourself weaker. You have confirmed to yourself you are weak in will power, and you have weakened your body's physical health. Perhaps this is because the ice-cream is not a good choice for your well being, and/or because you've condemned it and yourself. So now maybe you feel bloated, irritable, tired, or fatigued. Notice yourself. Your feelings of weakness will continue to manifest in you as you continue to offer them.
Now, if you take that same ice cream and say "I love myself. Is this the right choice for my well being?" You might actually put the ice cream down, or you might eat it. Be mindful and loving in whatever decision you make.
If you do eat it, decide to be mindful while eating it. Love yourself, observe yourself, and be non-judgmental. Ask what is the purpose of eating it? Are you actually hungry? Is there a feeling you are trying to gain, loose, or move? Feel the temperature and texture in your mouth. How do you feel with each bite? How does your mind and heart feel? How does your body feel? Is the food satisfying you? How do you feel after you've eaten it?
Embrace the moment for what it is and the gems of love and wisdom it has given you.
