Healthy fats for active people are less about a special list of foods and more about planning: knowing where fat comes from in your meals, how much fits on the plate, and when to keep it lighter around training. At our Samford gym we see two patterns. Some members are still eating as if fat should be avoided, and others have swung so far the other way that every meal is heavy. Here is the middle ground we use.
Where healthy fats for active people come from
Most fat in a good diet arrives as part of whole foods rather than added on top. The common sources in an Australian kitchen:
| Food | Typical portion | Easy way to use it |
|---|---|---|
| Extra virgin olive oil | 1 tablespoon | Dressings, roasting vegetables |
| Avocado | 1/4 to 1/2 | On toast, in salads and wraps |
| Nuts and seeds | A small handful (30 g) | Snacks, porridge, salads |
| Oily fish such as salmon or sardines | 100 to 150 g | Two or three dinners a week |
| Eggs | 2 to 3 | Breakfast, lunch boxes |
| Full-fat yoghurt and cheese | A tub or a matchbox-sized piece | Snacks, breakfast bowls |
How much fat on the plate
We use a simple hand guide rather than counting grams. For most meals, one thumb-sized serve of added fat is enough: a tablespoon of oil, a quarter of an avocado, or a small handful of nuts. Bigger people training twice a day may need two. If you are cooking in oil and then adding cheese and avocado on top, that is three serves before you have noticed.
Fat is energy dense, so a meal can be satisfying and still leave room for the protein and carbohydrate your training needs. That balance is the goal.
Timing fat around training
Fat takes longer to leave the stomach than carbohydrate. That is fine at dinner, but a big, rich meal an hour before a run or a heavy lifting session often sits uncomfortably. As a rule of thumb:
- Two to three hours before training: a normal mixed meal is fine.
- Within an hour of training: keep it lower in fat and fibre, such as toast with honey or a banana.
- After training: back to normal meals, fat included.
Our pre workout snack guide has more options for that final hour.
Reading labels for fats
Ingredient lists can be confusing. Words like emulsifier, food additive numbers and plant-based oils appear on everything from bread to chocolate. One that comes up a lot is lecithin, a natural mix of fats found in sunflower seeds, soybeans and egg yolk, used in food to keep oil and water mixed. If you have seen it on a label and wondered, here is a plain explainer: what is lecithin.
For most active people, the bigger win is not decoding every additive but cooking more meals from whole ingredients, which takes care of the label question by itself.
A sample day
- Breakfast: porridge with milk, a spoon of nut butter and berries.
- Lunch: wrap with chicken, salad and a quarter of an avocado.
- Afternoon snack before training: yoghurt and fruit.
- Dinner: salmon, potatoes and greens with an olive oil dressing.
Nothing exotic, nothing counted, and every meal has a modest serve of fat. For the training side of the week, our strength training over 40 guide explains how we program for adults who want to keep getting stronger.
Common questions
Should active people eat a low-fat diet?
Not usually. Fat is part of a normal, balanced diet. The aim is sensible portions and keeping it lighter in the hour before training.
Is butter a healthy fat?
Butter is fine in modest amounts as part of a varied diet. Most of our clients use olive oil for everyday cooking and butter where flavour matters.
Do I need fish oil or other fat supplements?
Most people can get what they need from food. If you rarely eat fish, adding two fish dinners a week is the simplest first step.
Can fat fuel a long run?
Your body uses a mix of fat and carbohydrate during exercise. For long or hard sessions, carbohydrate before and during still matters.
When to get it checked
If your energy, recovery or body weight is moving in a direction you did not plan, talk to an exercise physiologist about your training load, and we can point you to an accredited dietitian for a full eating plan.
