Michigan mom of 2 young kids

I am from Michigan and I have a 6 year old son and a 3 year old daughter and I was about 15 pounds overweight when I had my son and it took me a year to get back just to that weight after I had him. Then after I had my daughter I had about 20 pounds extra I have never been able to lose. So in total that is 35 but my goal is to lose 30 lbs. I have tried hard for a long time. We are organic, clean eaters and I have cut sugar out completely several times. Right now I am doing that again including honey and maple syrup and most breads. This time I have not been using goody lookalikes that use stevia as a substitute either. What I really need to do is count calories, which I know is a main feature of this site, but I did that a lot in my lower 20s and it took forever, and with young kids and VERY active lives I just don't have the time.
I also do Zumba for 1 hour twice a week, lift weights 2-3 times/week, and then change up the rest of what I do between dune hikes, exercise bike, and swimming. Sometimes the kids and I jog (younger kid in the jogger, older kid on his bike), do exercise videos on tv, etc.

I want to get healthy for the kids and myself, but my kids are a bigger motivator. Everyone in my family has diabetes and high blood pressure and my numbers are creeping up in both. Prediabetic and prehypertension ranges.
