If you are thinking of starting the LCHF/ketogenic lifestyle, I have to warn you of one thing. The LCHF/Ketogenic lifestyle is nothing you can do half assed. Either you do it or you don't. If you eat low carb high fat most of the time but continue eating some bread or other carbs most of the days, you will gain weight instead of losing weight. So make up your mind. Either you in or you out! A smart person would be in. Just saying ;)
