Take a look at your food log and Identify the items that are higher in fat then try to eliminate or reduce these foods from your diet. (hope that doesn't sound like Im teaching you to suck eggs as they say
but it is that basic).
as others have said you don't wanna eliminate fat altogether as mono- and poly-unsaturated fats are good for you. Also be careful of foods labelled low-fat as these often have added sugar to compensate for the taste lost with the fat. Most low fat dairy is ok (ie milk, cheese)
Things I have done:
-switch to skimmed/semi-skimmed milk and lower fat butter/margarine
-Use LF greek yogurt in place of creamy substances, eg. over veg stir fry and pasta with a dry spice/herb mix. in salad dressings, in dips, use half yogurt & half mayo in mixed salads like coleslaw or egg mayo.
-Use salsa, herbs & spices to add flavor to foods.
-Make omelets with 1 whole egg and 2 egg whites.
-And of course cut out the obvious chips, chocolate and snacks.
-As im a veggie I use 'Quorn' a lot which is a meat substitute, tastes great and is very low in fat, (my carnivore husband likes it too which is saying a lot)
For good fats I add, seeds, nuts, avocado and olives to my diet sparingly. Also the yolk of an egg has good omega fats too.
