Don't lose hope.... one day at a time. I'm on none of the special diets. No Keto, nothing. My dietitian told me to keep on eating what I am used to. Don't stop drinking Coke, just drink the no sugar version. I stay on a farm in the Karoo. No shopping malls and not a variety of food to choose from. I make our own double cream yoghurt of the cream of our goats milk and eat it with chia seeds and honey. Forgive yourself and just go on when you loose it sometime. I lost already 35kg of the 50kg I have to lose in 7 months. Don't make it difficult for yourself. Believe in yourself.
