As one transitions to the raw/vegan lifestyle, the tendency to overeat fats, mostly in the form of nuts is quite common.
It's understandable to eat large amounts of nuts when transitioning... they are more "filling" than fruits and vegetables and satisfy the hunger as your body adjusts.
In the long term, this can lead to many problems. In his book, The Raw Secrets, Frederic Patenaude describes this in detail and offers alternatives to avoid the difficulties and make the necessary adjustments. A full review of his book is coming up.
Many leading raw food proponents recommend a 80/10/10 ratio... 80% carbs, 10% protein and 10% fats.
In my experience, the urge to eat larger amounts of fat diminishes over time. Eating an adequate amount of fruits and vegetables along with seeds makes up most of your daily intake, satisfies you and lets you happily keep your intake of nuts to a minimum.
Keep it healthy and raw!
