Dear.............,
The first and most important issue is not to reduce the food you eat daily. You can change the menu and the way you eat but if you start a diet by yourself, the first thing you’ll lose is your health.
You can find many good gyms and if you want I can send the names for you in another letter. However, you don’t need to go to a gym to stay fit. Some small changes to your life can make a big difference. For example, you can start by walking sometime in the morning or at lunchtime.
I hope you don’t have any health problem and it would be nice if you went to a doctor for a check up before starting any exercise.
Best regards,
.............
