My daughter started cutting down March 1 for a meet that was yesterday. She just cut out the processed carbs and ate basically a ton of veggies and lean meats with a few small portions of rice here and there, fat free greek yogurt and hard cheese for dairy, fruits for the sweet tooth and no other liquids than water. She went from 66.5kg to 62.6kg at her weigh in, fully clothed at that. We didn't count macros at all because I didn't want her to get obsessive about it and it's a pain to do anyways. She trains 3 nights a week. Just keep it clean, if you need a carb up do it with oats, rice quinoa etc.
All month her lifts improved, and she finished with a 95kg total (42 snatch, 53 C&J) yesterday, 7 kg less than she has ever done in the gym. So I think it was a good success. She has another meet in 2 weeks and then a third mid May, so she will continue to maintain at this weight and we'll see how the lifts go.
