I have just started lifting again after a long break. I am 45, 6'2" and 210. I have always preferred being a little more on the lean side than too bulked up. I was rail thin as a kid.
My diet and drinking habits have not been too good over the last couple of years and I am thinking about trying a cleansing fast that a friend has done. It is three weeks long. Mostly herbal supplements and a colon cleanse for the first week with liquids only. The second week is small protein,(beans nuts) lots of leafy vegetables. Last week is working back into a normal diet but more with whole grain pasta & rice. I eat a mostly vegetarian diet anyway. A little chicken and fish. Most of my protein comes from eggs, beans, cheese and nuts.
Can anybody tell me what they think would happen to my muscle? I haven't been doing too much cardio. Mostly lifting and a couple of yoga classes a week to maintain flexibility.
