Low-fat Diet Sheet

A diet that is generally low in fat can help you to lose weight, or to maintain a healthy weight. Maintaining a healthy weight will reduce your risk of heart disease and stroke, diabetes and certain types of cancer. There are other conditions in which a low-fat diet is of use, such as gallstones.

If you want to lose weight, you need to eat fewer calories per day than you burn off in exercise. Foods which are high in fat contain a lot of calories, so cutting down on fatty foods is one way of losing weight. Very sugary foods also contain quite a lot of calories, but fat contains about twice as many calories as sugar per 100 g.

See separate leaflets called Healthy Eating for a more general overview of food and health, and Weight Reduction - How to Lose Weight which gives advice if you are planning to lose weight.

Not all fat is bad. Although all fats are high in calories, we need some fat in our diet, and some types of fat are actually good for our health. The different types of fat include the following:

Saturated fats

These are mainly found in animal products such as the fat on meat, in lard, and the fat in dairy products such as butter, full-cream milk, etc. Meat and dairy products have a useful role in a healthy diet, but try to avoid the fattier cuts of meat and use semi-skimmed or skimmed milk if you are trying to cut down on fat. Eating less saturated fat may reduce your risk of having a heart attack.

Trans fats

These are oils which have come from vegetables but have been processed to make them hard, so that they are easier to use in food. They are often used in processed foods, and in commercially made cakes, biscuits and pastries. Trans fats are generally bad for you and there is no place for them in a healthy diet.

Unsaturated fats

These mainly come from vegetables, nuts and fruits. They are divided into:

  • Polyunsaturated fats such as sunflower oil, and corn oil.
  • Mono-unsaturated fats such as olive oil and rapeseed oil.
  • Omega-3 fatty acids. These come mainly from oily fish such as pilchards, sardines, salmon, mackerel and fresh (not tinned) tuna. Omega 3 fatty acids are also present in some nuts and seeds, especially linseeds.

Omega-3 fatty acids may help prevent heart disease and improve our health in other ways. See separate leaflet called Cholesterol which gives more details about reducing your cholesterol level.

Unsaturated fats contain as many calories as saturated fats, but can form part of a healthy diet. If you are trying to lose weight, make sure that you are not eating too much unsaturated fat.

Foods that contain fat often contain a mixture of saturated and unsaturated fats. Food labels often list the amounts of each type of fat in the food (or at least how much of the fat in the food is saturated). As a rule, we should aim to limit our intake of saturated fats, and when we use fats and oils, mainly to choose those high in unsaturates. Food labels also show how many calories are in the food. So, it may be a good idea to get into the habit of reading food labels when you shop.
