Nutrition periodisation means matching food intake to your training goals and workload. Adjustments can support training and recovery without requiring a different diet every day. 1
Macrocycles and Nutrition
A macrocycle is the longer training plan, often a season or year. It can contain blocks focused on muscle growth, strength, competition and recovery. Nutrition should follow the purpose of each block. 1
Hypertrophy or bulking: consider a modest energy surplus, then adjust to progress. A fixed 200 to 400 kcal surplus is not a requirement for everyone. 2
In a small eight-week study, faster weight gain was more clearly linked to increased skinfold thickness than extra strength or muscle growth. Bigger surpluses are not automatically better. 2
Strength: fuel the actual session workload. A lower-volume strength block does not automatically need more carbohydrate than a high-volume hypertrophy block. 1
Cutting Without Neglecting Training
Use a manageable deficit, keep resistance training and prioritise protein. Retain carbohydrate for demanding sessions rather than simply removing it from the diet. 1
A four-week trial in young men found better lean-mass outcomes with 2.4 versus 1.2 g protein/kg bodyweight/day during a large deficit and intensive exercise. 3
That supports higher protein during restriction, not a universal 2.0 to 2.4 g/kg prescription. The study measured lean mass, which includes more than skeletal muscle. 3
For meal planning, keep a protein food such as fish, eggs, yoghurt, tofu or beans in your main meals. Adjust other portions rather than routinely shrinking the protein serving.
Caloric Cycling
Eating more on demanding training days can help match fuel to workload. But rest days may still require substantial food for recovery and preparation for the next session. 1
Try an extra rice portion or a banana before a demanding session. On an easier day, omit the extra if it is not needed. There is no automatic need to replace carbohydrate with more fat.
Do not assume cycling provides a metabolic advantage. ICECAP found similar fat loss and fat-free-mass retention with continuous restriction and diet breaks. 4
Those breaks lasted a week, so the trial does not directly answer whether alternating training-day and rest-day calories improves outcomes. 4
Deloads and Competition Preparation
During a deload, adjust intake to reduced workload without treating recovery as a crash-diet opportunity. Maintenance is a useful option, not a compulsory calorie target. 1
Before competition, rehearse familiar meals, fluids and event-specific fuelling. Plan any fat-loss phase well ahead rather than adding aggressive restriction near the event. 1

Tracking and Changing Phases
Set a review date rather than assuming every block must last 4 to 12 weeks. At review, consider your programme, goals, performance, recovery and weight trend together.
Start with consistent meals and portions. If progress is unclear, try a short food record to identify adjustments rather than assuming permanent, precise calorie counting is necessary.
BIA estimates body composition; hydration affects interpretation. It cannot confirm whether a short-term change represents muscle loss, so do not let one scan dictate a phase change. 5
See how to read a body composition scan.
Persistent fatigue, missed periods, recurrent injuries or distress around food warrant assessment by a GP and a sports dietitian. Under-fuelling is one possible cause, not a diagnosis from symptoms alone. 6
