Great Source of Protein with 0 Fat, 0 Cholesterol, 0 Carb...Is there such a thing???

A healthy balanced nutrition is made up of lean protein, whole grains, vegetables, and healthy fats. Even though you might think you're doing all the right things--exercising and eating right--but you might be surprised...
Case in point: a friend of mine--in his early thirties, exercises 3-4 times a week, eats healthy--recently went for a physical check-up. His doctor told him that he has high cholesterol and that he needs to reduce his meat intake and eat more vegetables.
He wanted to maintain his protein intake and cut cholesterol, so my suggestion to him was to substitute some of his meat intake with lean protein sources like egg whites. Egg whites are affordable, easy-to-cook, and contain no fat, no cholesterol, and no carb. They contain full chain amino acids that form a complete protein. Compare that with chicken breasts and fish, which are significant sources of cholesterol. All in all, these are healthy meats compared to red meats and pork. I would just recommend that you substitute some of your meats with egg whites. You can incorporate egg whites into so many different recipes including omelets, scrambles, protein shakes, and more. If you use raw egg whites in protein shakes, I recommend buying pastured egg whites. For more details about nutrition and exercise go here.

What's the best way to do cardio: Treadmill or Elliptical?

I've been asked this question almost every day, so it's clear that most of you have grappled with this question at one time or another.
First and foremost, you should stick to the machine that you enjoy using--whether that's biking, treadmill, elliptical, or even rowing machine--and do it consistently. The most important thing to ensure that your cardio workout is effective is keeping your heart rate between 60 to 85 per cent of your maximum heart rate. The easiest way to determine your maximum heart rate is by subtracting your age from 220. For example, if you are 30 years old, your maximum heart rate would be 190, which means your optimum heart rate for cardio exercises would be between 114 and 161 bpm depending on your fitness level.
Last but not least, you should alternate your activities and change up your routine every 2-3 weeks to avoid reaching a plateau.

How to trim your grocery bill and eat healthier

Saving money on grocery and eating healthy sounds impossible, but it’s actually not as difficult as you might think. Here are a few simple tips that can help you save hundreds of dollars and eat healthier:
Get volume discount by buying things in bulk at discount supermarkets or wholesalers. Prepare meals in advance that you can grab and go quickly. For example, cut up fresh vegetables, cook brown rice or pasta, and grill chicken breasts. This will reduce the urge to buy unhealthy and expensive to-go foods.
Avoid buying processed foods (think frozen entrees). They are usually expensive and unhealthy (e.g. loaded with sodium and chemicals).
Substitute meats with other protein-rich foods such as egg whites, low-fat, low-salt cottage cheese, beans, and soybeans.
