I've been thinking of going to a low-carb diet. Any advice on the best was to get started? For example, is it better to ease into it by slowly reducing carbs and adding fat or to dive right in and try to target 20-30 grams of carbs a day from the start? Any thoughts on why some people are successful at making the transition and others aren't? Is there an "adjustment" period where you might decide it's not working for you but it would have if you just stuck it out a little longer? Any tips or tricks to increase the chances of success?
