Most people know that adding a good source of protein at meal and snack times helps keep you fuller longer. Protein takes longer to breakdown in the stomach and helps stabilize blood sugars so the empty stomach feeling and hormones that signal hunger are delayed. Including a regular serving of protein at each meal and snack is a smart strategy to reach and maintain a healthy weight.
Not many people are aware that eating a consistent amount of protein regularly throughout the day is important for muscle strength. The research studies while relatively new, have similar results. They each suggest that the average American’s dietary habit of eating too little protein at breakfast and lunch and then eating far too much at dinner is not an efficient method for building muscle during the early hours and is wasteful at the end of the day. If you are a young person home for the summer with the goal of bulking up for fall athletics, middle age and concerned that your muscles are converting to fat as you embrace your desk all day or an older adult who desires continued strength and independence, listen up to the following findings.
The University of Texas released a study where healthy adults were fed 90 grams of protein differently throughout the day.
Group 1: 30 gms protein breakfast, 30 gms protein lunch, 30 gms protein dinner
Group 2: 10 gms protein breakfast, 15 gms protein lunch, 65 gms protein dinner
Group 1 experienced 25% more muscle synthesis by providing the right mix of nutrition to promote muscle growth and repair during the earlier hours.
Finally, many of us eat far too much protein to be beneficial. Recommended daily protein intakes are:
- Healthy adult: 0.8 grams/kg
- Endurance athlete: 1.2-1.4 grams/kg
- Resistance athlete: 1.6-1.7 grams/kg
A healthy adult weighing 160 pounds requires 58 grams of daily protein.
160 pounds divided by 2.2 pounds/kilograms x 0.8 grams/kg = 58
The average American consumes 90 grams of protein per day and would be better off balancing ½ their plate with more cost-effective fruits and vegetables. Just as a cup can hold only so much water, the same is true of muscle and protein. Too much protein may be burned as energy or worse, converted into fat when consumed in conjunction with too many calories.
