As I say...everyone is different. Protein seems to be my main requirement...too many carbs in nuts so I cut back to pumpkin seeds only...I am playing around with my diet again. I do know as we age we need LESS calories. :*))
We sure are all different. For weight control, the primary consideration is total calories per day. For me, at 1000 calories per day, I really don't worry about fats, sweets, or carbs solely for weight control. I certainly am concerned about nutrition, and my primarily veggie and nut diet seems to do the trick.
By the way, my nuts are almonds, and a generous handful is less than 2 gms. So, no big impact.
Along with the many doctors I see, I'm a firm believer that exercise and diet are the keys to a healthy life and aging well. The older we get the more important it becomes.
