Basically if you can see fat pads, the topline is indented at the spine, a cresty neck, etc they are definitely too fat. Often this is a problem with easy keepers as they age.. Like people developing Type 2 Diabetes, Insulin Resistance is a medical problem for some horses.
Removing them from grass, which may be too rich in sugars is a big plus. Feeding them a low fat LOW CARB diet is important. *no grain* The carbs being the most important. Often soaking their hay to remove any excess sugar possible will also speed the weight loss and help to prevent laminitis. Be sure to dump the water as waste as it is full of the sugar you are removing. ;) Hay can be soaked for 30-60 minutes then drained<shake off a bit> and feed. Prolonged soaking in hot weather can lead to sourness.
And don't forget exercise along with the diet.. :)
Do you have more info or a pic of this horse? Has she had any signs of laminitis? Hoof rings and/or abscesses are a big sign that there may be a problem. Been there.. ;)
