Hello XXXXXXX welcome back to HCM..

I've gone through your query and appreciate your concern for your mother..

First of all let me know her approximate height so that her obesity parameters can get calculated..

Secondly please upload the list of medications that she's taking (both for Diabetes and hypertension)..

When was her last health check up was done ? if possible please upload them so that I can obtain a detailed look at them to help you in a more specific direction..

The first and foremost step for controlling weight gain is physical activity, so tell her to start at least 40-45 min of daily mild-moderate exercises..(staring from brisk walking), after obtaining fitness from her treating Cardiologist..

Second thing is lifestyle modification, it's a broad term , means right from day to day routine activities to diet, sleep , habits etc.

Avoidance of junk foods/ processed foods/ sweetened fizzy beverages are of extreme importance..

Include a lot of green vegetables in the diet, avoid too much of dairy products, take whole grain foods instead of processed polished grains , drink a lot of water, maintain a strict 8 hrs sleep routine, avoid sitting too long in the couches , avoid fatty foods as well as red meat, include fish and mediterranean diet plans are of highly importance..

Next step is to consult a Dietitian for preparation of a comprehensive diet chart for her so that she can maintain them in a day to day basis(with emphasis on weight loss)..

With all these , she'll start loosing weight over a period of time ..

Let me know if any thing is not clear, I'll be glad to clarify..

Take Care
Kind Regards
