Your diary isn't open so I cant actually see what you are eating to get 50% fat.

No, 50% fat isnt healthy. Mine is around 30%. Some days I go over but usually those days include some kind of processed or fried food. Fat is important to the diet but It largely depends on where you are getting those fats.

Are you eating fresh fruits and veggies? Do you eat legumes, quinoa and other gf Grains? Those should be balancing your fat intake and providing your other macro numbers. I think I have my carb set at 40%, protein for 30% and my fat is 30%. Its about balance. Set your macros at a ratio that works for you and try to hit them. My carb number is naturally low but not because I am restricting it, I eat gf carbs in moderation they just dont add up as quick as wheat products do. I try to eat variety to meet my micronutrient requirements too.

You might try adding a protein bar like Quest to up the protein without the fat.
