S.H.
My mom has hypertension and before being put on meds for it, her doctor encouraged her to get more exercise, eat better food, and decrease her stress to try to lower the risks for her and her need for meds. My suggestion would be to get him in to the doctor to have a full physical. His doc will be able to better tell you what he needs to do to lower his risks and improve his health. There are some programs he can follow either at weight loss centers or even at a local gym where diet is an intregal part of training, but as always, you should consult your doctor first.
There are some common sense things that you can do in the meantime. I know my mom tried to eat pretty healthily, but she still needed to substitute portions of fruit for sweets, drink water instead of soda/soft drinks, tea, whatever. She also had to cut back more on chips and include more green foods into her meal plans. Breathing exercises or basic yoga can help lower stress and go take a walk nightly after your evening meal. Also, busy people tend to eat later at night. Maybe you could make a "food curfew" for yourselves generally 2 hours before going to bed (no one likes to be alone when they are doing this sort of thing). Ours is 7 pm. So, generally speaking, we have dinner at 6 pm, then we are completely done eating by 7 and in bed around 9 on a good night. Our bodies don't burn calaries at night as well as they do during the day. Also, to get that furnace burning in the morning, have something to eat to start your day. Just a yogurt or even a piece of toast is enough to wake up your sleepy stomach. I personally have lost a lot of weight and greatly improved my health by using these few tips as well as a few others. I balance and limit my portions both in size and in frequency and try not to eat starches at the same time as protiens... sometimes you just gotta have a sandwich, though... ;-}. I hope this is helpful. I know your focus is on his health, not his physique and I agree that THAT is the best focus. It sounds like you guys are a wonderful match and I wish you the best in your future marriage and congrats on your growing family!! Please let us know how things are in the future.
