Wife= mate lose wt. If you feel that you are being affected in a negative way---med conditions, high blood pressure, diabetes, can't exercise, short of breath, don't sleep well, don't like the way you appear, the weight affects your relationship; you may want to change. But, you, not your wife, need to want to make the changes. If you are not ready to make the changes necessary; no one else can. I hope you are ready.
Obesity initial tx. I recommend a patient try to change her environment as much as possible. Get support for childcare--so there is time to walk. Get an active job--or volunteer; helps you get out of the house. Find a group of friends who are also trying to lose weight. Enlist the help of a supportive spouse-or committ to working together to change your lifestyle. Eat healthy. Don't deprive yourself completely.
Stepwise approach. To tackle obesity, lasting change has to occur in how you eat, what you eat and whom you eat with. Making a single impactful change at a time, guided by your doctor, is a good way to start. Our drive for eating is very powerful so these changes are difficult. Some new medications may help with behavior change.
Healthy lifestyle. I recommend moderation, variety and balance. Portion control is a good start, learning what a portion size is and placing that into action. Increasing daily activity is also an important part of lifestyle changes. Try to be active most days of the week. In summary, eat less, move more is the general recommendation for someone with obesity.
