I limit myself to 30g of total carbs (minus fiber) a day so it forces me to be more honest with myself. If I am at 25g for the day and I need to make dinner for instance, it basically forces me to always pick the low carb version of a meal (veggies + meat).
I hope to one day be able to transition to a diet with more healthy carbs, but in the process I am focusing on working on better habits and losing weight.
