Healthy Eating for Your Active Lifestyle

Nourish Move Thrive

Most people don’t worry about their protein intake because they assume they are getting enough during the day. Chances are that you follow a typical dietary pattern of a low protein breakfast and lunch, and a much higher protein supper. If you are trying to build muscle, you may be sabotaging your best efforts. Did you know that the timing of protein intake is as important as how much protein you consume in a day?

Timing Your Protein Intake

How much protein are Canadians eating?

According to the Canadian Community Health Survey, Canadian adults get about 16% of their energy from protein. This is within the recommended range of 10-35%. To maximize the potential of protein, it is important to get enough at each meal and distribute it evenly throughout the day.

Traditional eating patterns

The typical pattern of eating is having a low protein breakfast (for example, a bowl of cereal with milk or a piece of toast with peanut butter). Lunch usually includes a moderate intake of protein (for example, a chicken salad sandwich). Dinner tends to be the high protein meal, with a piece of meat (for example, chicken, beef or fish). This pattern of eating results in about 12 grams of protein for breakfast, 20 grams for lunch and 60 grams for dinner.

Distribute protein throughout the day

Dr. Donald Layman, Professor of Nutrition, University of Illinois, is an expert in protein research in diet and exercise. He explains that the body does not store protein; it can only use a certain amount of protein at one time or at each meal. If you don’t eat enough protein, you run out of amino acids which are the building blocks of protein. Your body then has to break down muscle to make hormones, enzymes, hair, teeth and nails. In fact, every cell in your body needs protein for growth and repair. Eating protein throughout the day is better for building muscle and minimizes its breakdown.

Protein helps with snacking and cravings, too

Protein slows digestion and suppresses appetite. A recent study found that women who ate higher-protein breakfasts (35 grams) had more control over food cravings and appetite during the day and reduced their evening snacking.

In another study, 43% of middle-aged women who were followed over a two-year period said they ate more protein as a way to prevent weight gain. Those who reported eating more protein lost more weight.

Aim for 20-30 grams of protein at each meal

Optimize your protein intake by spacing your meals four to six hours apart and including 20-30 grams of protein at each meal. That translates into filling one quarter of your plate with a quality protein at breakfast, lunch and supper. Choose your protein sources from the food groups with the greatest amount and highest quality of protein: Milk and Alternatives and Meat and Alternatives.
