There was no weight gain,” says Dr Siddhant Bhargava, addressing a recent photo uploaded by Sara Ali Khan that suggested she had piled on a few kilos. “She had simply taken a break, and had gone to London. When she came back, she had to shoot for [a chat show], and had other commitments. She also had to walk the ramp. So she wanted to [get back into shape],” says the nutritionist, who has been monitoring Khan’s fitness and diet for several years.

Ever since Khan shared the image on social media, and revealed that she became ramp-ready in two weeks, netizens have been eager to know her process. While Dr Bhargava admits that losing a large amount of weight in a short period is not advocated, he says Khan had to adhere to the regimen owing to her professional commitments. “She was on a largely calorie-restricted diet. Usually, she consumes 1,700 calories, but we brought it down to 1,200. While cutting calories, we ensured she was put on an extremely  high protein diet. Also, since fibre is needed to [digest] protein, we added an adequate amount of it to her plate. Carbohydrates were limited to one meal alone. She was on 100 grams of protein, 70 grams of carbs and about 40 grams of fats. She was also working out like a beast.”
