Key Takeaways

Volume eating — maximising food volume per calorie — is the most effective hunger management strategy
Non-starchy vegetables provide the most food volume at the lowest calorie density
Protein at 30g+ per meal is the single most effective appetite-suppressing strategy
Water-rich foods (cucumbers, soups, salads) increase satiety 30–40% more than dry foods
Calorie-dense foods do not fill you up — nuts, oils, and cheese are nutritious but not satiating

The Calorie Density Principle

Different foods provide vastly different amounts of calories for the same volume. By prioritising foods with low calorie density (high water and fibre content), you can eat satisfying, filling meals while maintaining a calorie deficit.

Food Category	Calories per 100g	Volume for 200 cal
Cucumber / lettuce	12–15	1.3–1.7 kg
Broccoli / courgette	25–35	570–800g
Strawberries / watermelon	30–32	625–660g
Chicken breast (cooked)	165	121g
Brown rice (cooked)	130	154g
Almonds / nuts	580–650	only 31–35g
Olive oil	900	only 22g (1.5 tbsp)

12 cal

Per 100g of cucumber — maximum food volume, minimum calories

30–40%

More satiety from water-rich vs dry foods at same calories

200g

Greek yoghurt — 17g protein for only 97 calories

High-Volume Low-Calorie Meal Ideas

Breakfast (Under 400 cal, 30g+ protein)

3 egg white + 1 whole egg omelette + 200g spinach + tomatoes + 100g Greek yoghurt = 38g protein, 350 cal
200g plain Greek yoghurt + 150g berries + 30g oats = 22g protein, 300 cal

Lunch (Under 450 cal, 35g+ protein)

200g chicken breast + 300g mixed salad + olive oil spray + lemon = 46g protein, 380 cal
185g canned tuna + 200g cucumber + tomatoes + light dressing = 44g protein, 290 cal

Dinner (Under 500 cal, 30g+ protein)

150g salmon + 400g roasted broccoli/cauliflower + lemon = 42g protein, 420 cal
200g lean mince (5% fat) + courgette noodles + tomato sauce = 38g protein, 380 cal

✅ Volume Eating Rules

Fill half the plate with non-starchy vegetables first. Include 30g+ protein at every meal. Add water-rich foods (soups, cucumbers, celery, tomatoes) to increase volume. Measure calorie-dense foods (oils, nuts, cheese, grains) — these are where deficits disappear. Start meals with a large salad or broth soup to reduce total intake.

Frequently Asked Questions

How can I feel full on a calorie deficit?▼

Protein first (30g+ per meal), then fill the rest of the plate with non-starchy vegetables. Drink water before and with meals. Start with soup or salad. Eat slowly (20 minutes for fullness signal to reach brain). Prioritise whole foods over processed — they provide more satiety per calorie.

What foods have the most volume for fewest calories?▼

Non-starchy vegetables: cucumber (12 cal/100g), iceberg lettuce (14), celery (16), courgette (17), spinach (23), broccoli (34). Fruits: watermelon (30), strawberries (32), grapefruit (42). These foods allow you to eat large volumes while staying within your calorie target.

Is it healthy to eat a very low calorie diet?▼

Very low calorie diets (under 800 calories) require medical supervision. Eating too little increases muscle loss, nutrient deficiency, hormonal disruption, and metabolic adaptation — making long-term weight loss harder. A moderate deficit of 300–500 calories below your TDEE is safer and more sustainable.
