When Hrithik Roshan's trainer says four weeks is all it takes to transform your body, you better believe it

You will lose between eight to 10 kg of weight, and gain 1.5 to 2 kg lean muscle if you take his advice.

What to eatDr Rekha Sharma (in pic), president, Indian Dietetic Association, suggests a diet plan to match your workout. Fat gain and the onset of diabetes are largely due to skipping breakfast and irregularly eating patterns. To stay fit, you must eat something every 3 hours. Don't reach out for heavy meals. Nuts, fibre biscuits, fruit or a brown bread sandwich is enough to keep you going in between meals.

Eat a bowl of muesli or a peanut butter sandwich or a couple of bananas before your workout. Eat every 3 hours and continue with your regular diet for the first 10 days. But make sure you avoid foods made of maida (refined flour), fried snacks and white rice.

From the 11th day after the launch your new workout, start your day with two slices of brown bread, omelette/bhurji or 4 egg whites or soyabean bhurji, along with a glass of low fat milk. Snack on apples, papaya or oranges along with dates and nuts (almonds, walnuts, etc.) two hours after breakfast. Lunch must include a green salad, two chapatis, a vegetable, dal and chicken or fish. Cook all your food in minimal oil. Vegetarians can supplement their protein requirement with protein shakes. Make sure you read the ingredient make-up chart on the container to avoid those with steroids. For essential amino

acids, vegetarians can combine cereals and pulses to make multigrain dals and chapatis. 3 hours after lunch, have a sprout salad, bhel without fried sev or a brown bread sandwich. During the day, drink 4 litres of water and sip on coconut water and lime juice. Eat dinner by 8 pm. Cut down on carb intake — have 1 chapati and a vegetable soup, dal and sabzi. Eight hours of sleep is a must.

Maintaining your body after 30 daysOnce you have lost weight and gained muscle, work out for not more than four days a week. Following this 10-min routine daily will keep your body in shape for up to couple of months. Four minutes of skipping, fast walking or running, followed by one minute of squats, one min of push ups, half a min of chin ups, 1 min of plank and 45 secs of side planks each. "It'll make sure that blood reaches your muscles, preventing muscle loss. But do get back to working out, soon," says Chaurasia.
