This is around 8 o'clock. I add a handful of seasonal fruit to my breakfast. Then in he evening around 18-19:00 I eat, nuts (mainly walnut and hazelnut), green salad mix with yogurt. Sometimes I eat canned salmon, dried meat etc. sometimes I make small breakfast and eat boiled beef meat, organ meat soup (they are locally traditional in Turkey) sometimes I eat liver, steak and similar meat foods, if so, next morning I eat less. i bought a bicycle 3-4times per week, I am driving 32km I 1.5,hour, this is after work day at around 16:00 - 17:00. well no after 4months, I am 66kg. tension is around 11-12 (high), 6-7(low), resting pulse is 58-66/min.
