Diet is the crucial element in the success of your sporting objective, whatever it may be. If you want to dry out, your objective will be to get rid of the fat around your muscles to give yourself a lean physique!
Bear in mind that what you're looking for is to reduce your calorie intake enough to melt your fat, but not too much to avoid losing muscle mass. I promise, you won't turn into an anaemic salad-eating rabbit during your lean period.
To get off to a good start, use a calorie needs calculator to estimate your daily energy expenditure (DEE) and reduce your calorie intake by 10-20%.
But don't deprive yourself to the extreme! A moderate deficit of 300 to 500 calories a day is generally enough to lose around 0.5 kg a week.
Don't forget to go gradually, i.e. start with 200 kcal less one week, then 350 kcal less the next, and so on...
