That’s the thing isn’t it. Our cravings, habits or emotional drives to eat are always with us. They don’t disappear as we lost our weight - unfortunately. It’s a constant battle to manage them & reduce their power over us.
Portion size & calories. I’m only 2 years out but that’s the key for me. And nutritionally dense food of course. As you know if you eat more calories than your body needs to function you’ll put on weight. If you eat less than your body needs you’ll lose. Sure you could go back to protein shakes temporarily as a kick start to reduce your calories & start to break your cravings. Or you could follow keto or other diet for a couple of weeks too. But it really comes down to reducing those calories & portion sizes & making nutritionally sound food choices that will be sustainable in your lifestyle.
Can you go back to your dietician/nutritionalist for some hints & tips to refocus you?
