A 1,000 calorie diet is at the lower end of what health writers consider medically appropriate without general supervision. From an informational perspective, I want to be clear about both what this approach can achieve and its limitations. The key to making a VLCD as safe and effective as possible is prioritising protein, keeping meals nutrient-dense, and understanding this is a short-term tool — not a long-term eating pattern.

How to Allocate 1,000 Calories for Maximum Nutrition
7-Day 1,000 Calorie Meal Plan
Each day below targets approximately 1,000 kcal with at least 100 g protein. A daily multivitamin and mineral supplement is strongly recommended at this calorie level. Drink at least 2 litres of water daily.
| Day | Breakfast (~250 kcal) | Lunch (~300 kcal) | Dinner (~350 kcal) | Snack (~100 kcal) |
|---|---|---|---|---|
| Mon | Greek yoghurt (150 g, 0%) + berries | Grilled chicken breast (120 g) + salad | Baked salmon (120 g) + steamed broccoli | Boiled egg |
| Tue | 2 eggs scrambled + spinach | Tuna (130 g) + cucumber + 1 rice cake | Turkey mince (120 g) + courgette noodles | Apple |
| Wed | Protein shake (whey 25 g) + handful berries | Lentil soup (250 ml, homemade) | Cod fillet (140 g) + roasted asparagus | Cottage cheese (80 g) |
| Thu | Overnight oats (30 g) + soya milk + berries | Chicken salad (120 g chicken) + balsamic | Prawn stir-fry (150 g) + pak choi | Carrot sticks |
| Fri | 2 poached eggs + 1 slice wholegrain toast | Turkey wrap (half) + large salad | Grilled mackerel (120 g) + steamed spinach | Handful mixed nuts (15 g) |
| Sat | Smoothie: pea protein 25 g + almond milk + banana (half) | Chickpea salad (100 g chickpeas) + veg | Chicken breast (120 g) + roasted peppers | Celery + 1 tbsp hummus |
| Sun | Greek yoghurt (150 g) + 1 tbsp chia seeds | Smoked salmon (80 g) + rocket + lemon | Lean beef mince (120 g) + stewed tomatoes | Boiled egg |
What to Do After the 1,000 Calorie Phase
Abruptly increasing calories after a VLCD can lead to rapid weight regain and metabolic disruption. A structured transition is important:
- Weeks 1–2 post-VLCD: Increase to 1,200–1,300 kcal with additional complex carbohydrates and healthy fats
- Weeks 3–4: Increase to 1,400–1,500 kcal and introduce structured resistance training
- Ongoing: Settle at a moderate deficit (300–500 kcal below TDEE) for continued, sustainable fat loss
