If you are new to exercise, it’s important to watch what you eat to achieve your best results. Oftentimes I see people begin getting in shape, but they eat like a rabbit. Substituting a salad for a beautifully grilled ribeye is a mistake!
Protein provides the building blocks to build muscle. If you rob your body of protein, your body will turn on you. It requires you to feed it what it needs.
A word of caution: there are people who swear by an all-beef diet. You should find what is best for you. A diet without fresh vegetables might not be optimal. Do some research. Consult a nutritionist. Your body is a machine. Treat it right and it will last a long time.
Lifting weights, Pilates and walking are a nice combination. Try them, but don’t forget the protein!
