Hi and Congrats on your weight loss and getting started! Just my opinion - but I wouldn't add any extra fiber to your diet right now. It is normal to go through these changes as our bodies adjust to an entirely new way of eating. The body has its own wisdom and will "go" when it needs to. Make sure you are getting your veggies in, drink more water, and walking is good too. Being regular is really our thing and the body does a good job of taking care of itself. And it will adjust! Good Luck!
