The doctor is in

Till now, the available medical literature and research conducted shows no link between bites of mosquitoes, ticks or bugs—including bed bugs—for transmitting HIV infection. Thank God for that.

• I am 48, height 157 cm. At 78 kgs, I think I’m grossly overweight. When I climb the stairs, for instance, I feel a mild pain in the knee. I’m doing yoga for 30 minutes daily. Is there anything else I should do? — Ramesh Patel

Ishi Khosla, Clinical Nutritionist, says:

Try a combination of diet and exercise. Eat a low calorie, high fibre diet. Include whole grains and a lot of veggies as filler. Avoid food which has a high glycemic index—sugar, potatoes, rice flour, excess fruit sugar and fruit juices. Pulses in moderation and low fat dairy is fine. Use olive and sesame oil as cooking medium.
