Do I have to eat all of my fat target?

No! The figure on the website is based on the recommendation that no more than 35% of your total daily calories should come from fat. It's not a requirement that you must eat all the amount stated – treat the figure as a maximum limit that you should not exceed.

If you do find yourself eating less, that's fine but stick to around two-thirds of the target, don't eat less than half as fat (especially the good type) is essential for the healthy functioning of your body.

Diets that are classed as 'low fat' tend to reduce fat intake to between 20-25% of total daily calories. So based on a daily target of 1,400 calories, this equates to 31-39g fat per day. There is no official minimum figure, but it is not recommended to go below 25g fat per day as this starts to restrict you from having a balanced diet.

Try to choose good fats – these are found in vegetable sources such as nuts and seeds and avoid unhealthy saturated fats – these tend to be found in higher fat dairy products, the visible fat on meat and processed meat products such as sausages, pies and pates. Also steer clear of unhealthy trans fats – found in many processed products and take away foods.

Fat is the most concentrated source of calories at 9 cals per gram – that's twice the number of calories in 1 gram of carbs and protein. So it makes sense that sensibly reducing your total fat intake, is a very effective way of lowering the number of calories in your diet.
