Hey I’m also doing keto!! What you’re describing as far as going back and fourth on the diet can be called a “carb cycle”. Google it. You do low card for a few days, high carb for a few. It’s especially good if you work out. I think you may be losing control because you may be restricting too much. When I first started this diet, I was cranky and i have binged a few times but only on low carb foods. Never gained weight from that either. Perhaps the lack of carbs is a shock and your body just wants to eat everything in sight after awhile. It’s not uncommon. Let yourself have a relax/cheat day. Don’t be so hard on yourself. It sounds like you may be getting depressed though during your binge days. It could be a bit of clinical depression or self doubt. People don’t understand that diets also effect us mentally. Good luck and don’t be so tough on yourself. ((Hugs))
