Tips for Healthy Living!

Alpharetta & Cumming Internal Medicine

We’re sure you keep hearing about healthy eating but what constitutes a healthy well balanced diet? What if were as simple as cutting out meat a few days a week and replacing it with plant based protein? A healthy diet is all about balancing diet and active lifestyle, and plant protein can help you maintain that balance and maybe help you shed a few pounds.

Can’t Seem to Lose Weight?

It has been reported that those who eat diets with reduced animal protein weigh 15% less than everyday meat eaters. Dr. Oz on the Today Show (Jan. 1, 2017) suggested that if you were having difficulty losing weight, even when cutting calories and carbs, that reducing meat intake and replacing with plant based protein could be the secret to finally shedding some pounds.

Other benefits found from consuming less animal based protein are lowering heart disease risk, lowered blood pressure, decreased risk of cancer and reducing the threat of type 2 diabetes.

Another benefit in helping to lose weight is the fact that plant based protein foods keep you feeling full longer so that you can consume less calories. Here are some of the best protein rich vegetables you could use to substitute for animal protein according to

  • Tofu
  • Lentils
  • Avocado
  • Steel cut Oatmeal
  • Broccoli
  • Brussels Sprouts
