Salve, I am 40 years old and my weight is 180 pounds. I am not much conscious about my health as I do regular exercise in the morning like, push-ups, bench press and walking on the treadmill. I am a non-vegetarian and try experimenting with different non veg items. I have never had beef but now I am really looking forward to eat it. I have no idea about the amount of calorie in beef, I think it is full of fat and can be dangerous for health. Is it true? By the way, tell me about the calories in 140gm of beef?
