Archimedes always has excellent advice.
You need to do something about the blood pressure, right? You've got kids you need to be able to take care of. You won't be able to live life to the fullest with high blood pressure, will you?
Maybe life doesn't want you on a diet, but maybe it wants you to make healthy choices so that you can enjoy your life.
This isn't something that you are going to be able to do in a couple of weeks, and then go back to what you were doing before. So pick a couple of changes for this week. Start with some simple things. Play outside with the kids on the weekends. Drink water. Make sure you have a salad every day. Replace whatever snacks you are currently having for fresh fruit. Use the nutrition tracker. It almost doesn't matter what you chose. It takes 21 days to make a habit, so start right now, and make 2 or 3 changes. Maybe next week, you can start 2 or 3 more, and so on. That way, you might be able to sneak some positive changes in without getting bored or overwhelmed.
Another possibility to avoid boredom is to keep changing things up. Try new foods. Lots of ethnic cuisines use lots of vegetables and are low in fat. Try vegetables or fruits you've never tried before. Make it an adventure. You can view exercise the same way. Try something that you haven't done before. Cross country skiing. Orienteering. Kayaking. Work in fun family activity every week, whether it's a trip to the playground, or the pool, or a hike at the park, or a bike ride, or a kickball game.
Of course, make sure that your doctor has cleared you for exercise!
