Pakistani actor Nimra Khan has revealed she lost a whopping 8 kg following a crash diet for a week. The 34-year-old revealed she ate just green apples, green tea, and egg whites to sustain her day, a regime Nimra found extremely tough to follow. According to experts, such crash diets temporarily fulfil your weight loss goals but come with extreme side effects like heart issues, hair fall, mood swings, and slow metabolism.
