According to yog and aayurved, the recommendation is to limit(not avoid) fibre-based, protein-based and fat-based food. Too much fibre and protein is bad for the digestion system and too much fat is bad for the body. Two tablespoon of Ghee(i.e. pure butter) everyday is recommended and is enough for the body. Also, the recommendation is to wake up at 4:00 am, mediate and/or exercise, drink a glass of warm(not cold) water before lunch, have lunch before 7:00 am, stomach should be max 2/3 filled after lunch, eat fruits and dry fruits the rest of the day whenever you feel hungry, drink warm water whenever you feel thirsty, have lite dinner before 5:00 pm, and sleep at 8:00 pm before doing some meditation.

That is the recommendation for a calm, refreshing and healthy life.
