1️⃣ Start conservatively with your deficit. Going to the extreme right away isn’t something you should do. See how you respond then adjust.
2️⃣ Match your nutrition to your training needs. Make sure you are matching your carbohydrates to your training, supporting performance in workout and recovery. Keep performance high, burn more calories in workout and create better oxygen deficits in training.
3️⃣ Avoid excessive, over training. No need to try and kill yourself in a long, hard workout. Understand what you are trying to achieve with your workout and have a plan. More sets or reps should not be the goal.
