About staying trim: Its a combination of both my genetics and lifestyle. Ive always been naturally underweight my whole life. Its difficult for me to gain weight unless I try really hard.
My diet is relatively healthy too, like fruits, cereal, meat, whole grains, anything that is filling nutritionally. When it comes to liquids, I only drink water or fruit juice. Besides that, I try to avoid eating too much sweets
Cycling is an excellent way to stay lean! Did you know that was my hobby? As far as genetics, I used to be trim and lean, I changed after my sister passed and I am on my way back to health after a rocky 5 years. Even my blood pressure is normal now! I sound like an old dude, but it is true, stress can cause all sorts of health problems.
