It's important to choose nutritious food rather than gimmicks. Just because a product boast "low fat, sugar free, low carb, gluten free, non-gmo, all natural," etc. does not mean it is a healthy choice. It may be... but it could be just the opposite. Also don't assume a lower calorie food is always the best option. Many low calorie foods have very little nutritonal value and may be filled with unwanted chemicals.
Healthy eating does not require that you consume protein shakes, magic energy drinks, or live on nutrition bars. A healthy food plan should instead have a very high percentage of fresh fruits and vegetables, lean meats, and whole grains. The closer the food is to it's natural state the better.
Be sure to combine your healthy eating plan with well balanced exericse program. Making healthier choices is not just good for your waist line. It's good for your overall health and reduces your risk of many diseases.
