High Calorie Meals: What They Are and How to Build One

Quick answer: A high calorie meal is one made mostly of calorie-dense foods, so a smaller portion carries more calories. The principle is the same at every meal: start with a calorie-dense base, build calories in with fat such as oil, butter, cheese or nut butter, then finish with a rich topping or a drink. Done this way, a normal-sized meal reaches 700 to 1,000 calories and still fits on an ordinary plate. For the foods this is built on, see calorie-dense foods.

This page is the overview. It covers the one idea that runs through every high calorie meal, then points you to the right guide for each meal of the day, where the specifics live. If you are eating more to put on weight, start with how to gain weight.

I have spent years working out the smallest, easiest way to get more calories into a meal, and across breakfast, lunch and dinner it always comes back to the same lever: fat, added during cooking or assembly, where it adds calories without adding bulk.

What makes a meal high in calories?

Calorie density. That is how many calories a food holds for its weight. A meal is high in calories not because there is more of it, but because what is in it is concentrated.

Fat is the reason. Gram for gram it carries 9 calories against 4 for carbohydrate or protein, so a spoonful of oil, a slice of cheese or a dollop of nut butter changes the calorie total far more than another serving of vegetables would. This is why a small, rich meal can carry as many calories as a large, plain one.

How do you make any meal higher in calories?

Three moves cover almost every meal. The ingredients change by meal, but the method does not.

Start with a calorie-dense base. Bread, pasta, rice, potatoes or oats give you a solid floor to build on, rather than starting from salad leaves.

Build the calories in with fat. This is the big one. Cook in oil or butter, choose a creamy or oily sauce, spread it thickly, or stir in nut butter. A tablespoon of olive oil is roughly 120 calories, 30g of cheese around 125, and two tablespoons of peanut butter about 190, none of which adds much bulk.

Finish with a rich topping or a drink. Nuts, seeds, cheese, a drizzle of oil, or a calorie-dense drink alongside top the meal up. A glass of whole milk adds about 130 calories on its own.

The specifics differ by meal, which is what the guides below are for.

What does a high calorie day look like?

Here is how the meals fit together across a day, with a rough figure for each. Follow the links for the detailed version of each one.

Breakfast sets the tone, and it is easy to make dense with oats, whole milk and nut butter. A bowl of overnight oats lands around 650 calories. See high calorie breakfast ideas.

Lunch is the meal that has to travel, so it pays to make it compact. A loaded sandwich with avocado and cheese is around 800 calories. See high calorie lunch ideas.

A snack or two between meals does quiet, steady work. A Phoenix Bar is up to 557 calories with nothing to prepare, and a yoghurt pot with granola and nuts is around 400. See high calorie snacks.

Dinner is the easiest meal to add calories to, because you are cooking it and can build the fat in. A coconut chickpea curry with rice is around 850 calories. See high calorie dinner ideas.

Dessert is the simplest and most pleasant top-up, already built around fat and sugar. A rich pudding or a milkshake is around 500 calories. See high calorie desserts.

That comfortably passes 3,000 calories across the day without any meal being enormous. If you want a structured plan built around a daily figure, see the 3,000 calorie meal plan. For liquid calories at any point, see high calorie drinks and smoothies.

What if a full meal is too much?

If a full plate is too much, the answer across every meal is the same: shrink the volume rather than forcing down more food. Keep a Phoenix Bar to hand, with up to 557 calories in only 120g; otherwise, eat the densest part of the meal first or swap a plate for a drink. The best meal replacement bars guide explains how a meal-sized bar differs from a diet bar.

This is the harder version of the problem, and it has its own guide on what to eat when you fill up after a few bites.

It is also the problem Phoenix Bars were built for. Each bar holds up to 557 calories in only 120g, is vegan and gluten-free, and mixes into porridge with water or milk. Our high calorie bars follow the same idea as every meal on this page: maximum calories in the smallest, easiest format.

Are high calorie meals unhealthy?

Not by definition. Calorie density tells you how many calories a meal holds for its weight and nothing about its quality. Plenty of calorie-dense meals are built from whole foods: oats, nuts, nut butter, olive oil, full-fat dairy, eggs, beans and wholegrains.

A lot of advice online treats high calorie and unhealthy as the same thing and steers you towards lighter options. If your aim is the opposite, to take in more calories, then rich meals made from real ingredients are the straightforward way to do it.

Frequently asked questions

What is a high calorie meal?

A high calorie meal is one made mostly of calorie-dense foods, which lets a normal-sized portion carry a lot of calories. It usually means roughly 700 calories or more for a main meal. The calories come mainly from fat: oil, butter, cheese, cream, nut butter, nuts and full-fat dairy.

How do I make my meals higher in calories?

Add fat. Cook in oil or butter, make sauces creamy, spread things thickly, stir in nut butter, and top with grated cheese, a handful of nuts or a swirl of oil. Each of these adds 100 to 200 calories with very little extra volume, so the portion stays the same size.

What are some high calorie meal ideas?

Overnight oats with peanut butter for breakfast, a loaded sandwich for lunch, a coconut curry or pasta bake for dinner, and a rich pudding for dessert. Each leans on a calorie-dense base plus added fat. The meal-by-meal guides on this page cover each in detail.

What are cheap high calorie meals?

The cheapest calorie-dense staples are oats, rice, pasta, potatoes, eggs, beans, lentils, peanut butter and whole milk. Build meals on these, add oil for extra calories, and batch cook to save time and money. A rice bowl with beans, cheese and olive oil is filling, cheap and calorie-dense.

How can I do high calorie meal prep?

Batch cook calorie-dense bases like rice, pasta and curries, then portion and freeze them. Keep quick add-ons to hand, such as cheese, nut butter, oil and nuts, so you can lift the calories of any reheated meal. Curries, stews and pasta bakes all freeze and reheat well.

What is a high calorie vegan meal?

Plenty of plant foods are dense in calories: olive oil, coconut milk, nut butters, tahini, avocado, nuts, seeds and dried fruit. A vegan high calorie meal could be a coconut chickpea curry, a bowl of peanut noodles, or an olive-oil pasta, any of which can reach 700 to 850 calories.
