This 1800 calorie meal plan lays out a full day of eating — breakfast, lunch, a snack and dinner — that adds up to about 1,800 calories, with around 130 grams of protein. There is nothing to calculate and nothing to guess: every meal is spelled out with portions and calories, so you can follow it exactly as written or use the swaps further down to make it your own.
If you have been looking for a diet plan at 1800 calories that is built around normal food rather than supplements or tiny portions, this is it. The meals are filling, they use ingredients you can buy in any supermarket, and the whole day can be prepped in under an hour.
Who an 1,800-calorie plan suits — and who it does not suit
1,800 calories is a moderate intake. It tends to suit adults who are lightly to moderately active and want to lose weight gradually, or people maintaining their weight on a smaller frame. It is also a sensible starting point if your maintenance calories sit around 2,100 to 2,300 and you want a gentle deficit of roughly 300 to 500 calories a day.
Before you commit to a number, it is worth checking your own figures. Our Maintenance Calories Calculator estimates how many calories you burn in a day, and our guide to how many calories you should eat to lose weight explains how to turn that number into a daily target.
An 1,800-calorie plan is not right for everyone. It is probably too little if you are very active, do heavy physical work, are pregnant or breastfeeding, are under 18, or have a history of disordered eating. If you are a larger, very active man, your maintenance level may be well above 2,500 calories, and 1,800 would be an unnecessarily steep deficit. In any of those cases, use the calculators above to find a target that fits you, and talk to a doctor or dietitian if you are unsure.
The full day: 1,800 calories, meal by meal
Here is the day at a glance. All calorie counts are approximate — natural foods vary, and the totals are rounded to the nearest 5 calories.
| Meal | What you eat | Calories | Protein |
|---|---|---|---|
| Breakfast | Oats with Greek yogurt, blueberries, chia seeds and honey | 455 | 28 g |
| Lunch | Grilled chicken, quinoa, salad and feta | 575 | 53 g |
| Snack | Apple and almonds | 155 | 3 g |
| Dinner | Baked salmon, brown rice and broccoli | 600 | 46 g |
| Day total | 1,785 (about 1,800) | 130 g |
That is 455 + 575 + 155 + 600 = 1,785 calories, which we round to about 1,800 for the day. Protein comes to 28 + 53 + 3 + 46 = 130 grams.
Breakfast: 455 calories
- Rolled oats, 50 g (190 calories)
- Nonfat Greek yogurt, 150 g (85 calories)
- Blueberries, 100 g (55 calories)
- Chia seeds, 12 g (60 calories)
- Honey, 1 teaspoon (20 calories)
- Semi-skimmed milk, 100 ml (45 calories)
Make the oats with the milk, then top with the yogurt, blueberries, chia seeds and a drizzle of honey. It takes five minutes, keeps well overnight as overnight oats, and the combination of fiber, protein and healthy fat is what keeps you full until lunch.
Lunch: 575 calories
- Grilled chicken breast, 130 g (215 calories)
- Cooked quinoa, 180 g (215 calories)
- Mixed salad vegetables (30 calories)
- Olive oil, 1 teaspoon (45 calories)
- Feta cheese, 25 g (70 calories)
Grill the chicken in batches on Sunday and this lunch becomes a two-minute assembly job all week. Dress the salad with the olive oil and a squeeze of lemon, and crumble the feta over the top.
Snack: 155 calories
- Medium apple (95 calories)
- Almonds, 10 g (60 calories)
Simple on purpose. The crunch and sweetness break up the afternoon, and the almonds add just enough fat and protein to stop the apple from leaving you hungry again in half an hour.
Dinner: 600 calories
- Baked salmon fillet, 140 g (290 calories)
- Cooked brown rice, 180 g (200 calories)
- Broccoli, 200 g (65 calories)
- Olive oil, 1 teaspoon (45 calories)
Roast the broccoli with the olive oil while the salmon bakes — one tray, one pan, dinner in about 20 minutes. If salmon is not your thing, the swaps table below gives a cod version that saves about 140 calories.
Macros for the day
Across the whole day, the plan works out at roughly:
- Protein: about 130 g (29%) — comfortably inside the 120–135 g range that suits most people at this calorie level, and enough to protect muscle while you lose weight.
- Carbohydrates: about 190 g (42%) — mostly from oats, quinoa, rice, fruit and vegetables.
- Fat: about 59 g (29%) — from olive oil, salmon, chia seeds, almonds and feta.
Percentages are shares of the day’s energy from each macro, and all figures are approximate. If you prefer more carbs and less fat, or the other way around, the swaps below let you shift the balance without moving the total far from 1,800.
Easy swaps that keep the day at 1,800 calories
Use these swaps to adjust the day to your taste, budget or what is in the fridge. Each saving is approximate and applies to one meal, not the whole day.
| Swap | You save (approx.) |
|---|---|
| Feta 25 g (70 calories) → cottage cheese 50 g (50 calories) | 20 calories |
| Honey 1 teaspoon (20 calories) → extra berries | 20 calories |
| Olive oil 1 teaspoon (45 calories) → cooking spray | about 40 calories |
| Chicken breast 130 g (215 calories) → tofu 150 g (130 calories) | 85 calories |
| Brown rice 180 g (200 calories) → cauliflower rice (60 calories) | 140 calories |
| Salmon 140 g (290 calories) → cod 140 g (150 calories) | 140 calories |
| Almonds 10 g (60 calories) → carrot sticks (20 calories) | 40 calories |
If a swap takes you under 1,800, add the difference back with something you enjoy — an extra piece of fruit, a larger portion of vegetables, or a square of dark chocolate. A plan you enjoy is a plan you will actually follow.
The full vegetarian version of the day
Here is the whole day rebuilt without meat or fish. Breakfast and the snack stay the same; lunch and dinner change.
| Meal | Vegetarian menu | Calories |
|---|---|---|
| Breakfast | Oats with Greek yogurt, blueberries, chia seeds and honey | 455 |
| Lunch | Chickpea and quinoa bowl: chickpeas 200 g, cooked quinoa 180 g, salad vegetables, olive oil 1 teaspoon, feta 25 g | 600 |
| Snack | Apple and almonds | 155 |
| Dinner | Lentil and feta stuffed peppers: cooked lentils 200 g, brown rice 150 g, feta 40 g, olive oil 1 teaspoon, peppers and tomato | 600 |
| Day total | 1,810 (about 1,800) |
One honest note: the vegetarian day runs lower on protein, at roughly 85 grams. If you want to match the main plan’s 130 grams, add a protein shake, an extra serving of Greek yogurt, or a portion of tofu at lunch — each adds 15 to 25 grams without pushing the day far past 1,800 calories.
How to stay full on 1,800 calories
- Front-load your protein. A high-protein breakfast makes the rest of the day noticeably easier.
- Keep the volume up. Vegetables, salad and broth-based soups add bulk for very few calories — use them to pad any meal that feels small.
- Do not drink your calories. Water, tea and black coffee are free; juice, lattes and alcohol can quietly eat a quarter of the day’s budget.
- Eat on a schedule. Three meals and one planned snack beats grazing, because grazing rarely registers as eating.
- Sleep and steps count. Poor sleep raises hunger hormones, and a daily walk makes a modest deficit feel easier than sitting all day.
One-day shopping list
Everything you need for one day of the main (non-vegetarian) plan:
- Rolled oats, nonfat Greek yogurt, blueberries, chia seeds, honey, semi-skimmed milk
- Chicken breast, quinoa, mixed salad leaves, cucumber, tomato, feta cheese, olive oil, lemons
- Apples, almonds
- Salmon fillet, brown rice, broccoli
For the vegetarian version, swap the chicken and salmon for chickpeas, lentils and peppers, and add an extra block of feta.
If 1,800 calories turns out to be slightly too much or too little for you, our 1700 Calorie Meal Plan and 1400 Calorie Meal Plan follow the same simple format at lower calorie levels. And remember: every total in this plan is approximate, so weigh portions for a week or two if you want accuracy, then relax into the routine once you know what the portions look like.
Is 1,800 calories enough to lose weight?
For many people, yes, as long as 1,800 calories is below what you burn in a day. Weight loss comes from a sustained calorie deficit, so the real question is how 1,800 compares with your maintenance level. If your maintenance is around 2,100 to 2,300 calories, 1,800 gives a gentle deficit and steady loss.
How much protein on an 1800 calorie meal plan?
This plan provides about 130 grams of protein a day, which sits inside the 120 to 135 gram range that works well for most people at 1,800 calories. That is roughly 29 percent of daily energy. Spreading it across meals, about 28 grams at breakfast, 53 at lunch, 3 at snack and 46 at dinner, helps with fullness and protects muscle while you lose weight.
Can I meal prep this plan?
Yes, this plan meal preps very well. Cook the quinoa, brown rice, chicken and salmon in batches, and store them in separate containers for up to four days. The oats bowl can be made as overnight oats, and the snack needs no prep at all. Keep dressings and the feta separate until serving so salads stay crisp.
What if I am still hungry on 1,800 calories?
First, add volume rather than calories: extra vegetables, a big salad or a broth soup will fill the plate for very few calories. Next, check that protein is spread across the day, since a low protein meal leaves you hungry again quickly. Drink a glass of water and wait 20 minutes before deciding you need more food. If hunger is constant after a week or two on the plan, 1,800 calories may simply be too low for you: check your maintenance level and consider a smaller deficit instead of pushing through.
Is an 1800 calorie diet safe long term?
For most healthy adults, yes, provided meals stay varied and nutrient dense like the meals in this plan. At 1,800 calories there is room for protein, fiber, fruit, vegetables and whole grains every day, which is what makes a plan sustainable. It is not suitable for under 18s, during pregnancy or breastfeeding, or for anyone with a history of disordered eating. If you feel persistently tired, dizzy or unwell, eat more and speak to a doctor or dietitian.
