Do you prefer to satisfy your taste or manage your waist? What’s more important to you? If I look, I will be able to see which you prefer.
There may not be a right or wrong. However, if you want one but focus on the other, happiness will elude you.
If you let yourself drift along, it will be harder for you. Being determined, committed and following through will give you a feeling of having a super power. You will love it!
Think of sugar as poison. Eating poison, or items with poison in them, would be terrible for you. Stop thinking sugary items are a treat. They are more of a threat to your health.
Focus on your waist but allow moments of taste to be fully enjoyed. Enjoy and even savour the taste of all food and drink you consume. Linger on it. Enjoy!
