Hi Karan,
to calculate your calorie intake, you ll have to first calculate the current calorie intake which you can calculate by tracking your diet on the lifemojo website, it will automatically calculate your current calorie intake, then you need to substract 500 cal per day to bring a weight loss of around 500 gm per week. if you do it succesfully you ll be able to lose the extra 5 kg in 10 weeks.
yes salt intake sure helps in losing weight. excessive salt intake leads to water accumulation in the body cells , it also increases the thirst and you intake more water, leading to further water retention and hence increases in the water weight content ! so decreasing salt will definately help you. all the best for your weight loss journey !
