The benefits of eating protein for healthy and achievable weight loss
- 5 Minutes Read
Claims about protein are everywhere, but what are the benefits of eating protein as part of a healthy diet? Read about how protein is vital for weight loss. Learn how MyNetDiary calculates your protein needs and discover rich protein sources to add to your diet.
Dietary protein is critical to health because of the amino acids or building blocks of proteins. We use amino acids for growth and development, cell generation, hormone and enzyme building, and other functions like supporting a healthy immune system! Eating protein daily is vital for ensuring health.
You can meet your daily protein needs from both plant and animal foods
Some animal proteins are higher in calories because of fat. Choose lean cuts, trim excess fat, and avoid deep-fat frying to ensure you reap the benefits of protein-rich foods without the extra calories.
Plant-based proteins, such as dried beans and peas (legumes), soybeans, nuts, seeds, and grains, are t
To achieve weight-loss success, you must meet your protein needs daily. Since protein takes longer to digest than carbohydrates, you may stay full longer by eating protein at each meal. Eating enough protein combined with a strength-training routine helps preserve muscle mass as you lose weight.
More protein isn’t necessarily better and excess protein won’t increase muscle growth. You may gain weight if you exceed your calorie budget by overeating protein.
Tip: Aim for at least 60g/day of protein on a reduced-calorie diet.
Since many MyNetDiary members are trying to lose weight or manage blood sugar, we use a macronutrient target to encourage healthy proteins and fats while controlling carbs.
MyNetDiary’s default recommendation for protein is 20% of total daily calories, within the Acceptable Macronutrient Distribution Range of 10-35% of total calories.
If you prefer a different protein target, customize your goals with a Premium MyNetDiary membership, as seen below:
You can also plan your protein needs based on your body weight. The US Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram (or about .36 g per pound) daily.
For example, for someone weighing 180 lbs. (82 kg), their RDA for protein is 65 grams (82 kg x 0.8 g/kg).
Tip: Divide pounds by 2.2 to get kg.
The modest RDA target may be too low for some. Many reduced-calorie weight-loss plans suggest 1.2-1.5 g per kg. Athletes, older adults, and those trying to build muscle may also benefit from a higher intake than the RDA. Read here for more information on starting a higher-protein plan.
Those with certain kidney and liver conditions may need to limit protein intake. Follow the advice of your doctor or dietitian.
The human body uses 20 amino acids, nine of which are considered “essential,” meaning they must come strictly from the diet. Animal proteins (meat, fish, poultry, game, eggs, and dairy) are “complete,” so they provide all the essential amino acids needed to build proteins. Since plant proteins are often low in one or more essential amino acids, eating a variety of plant proteins throughout the day will ensure you get enough of each essential amino acid.
Athletes may pay special attention to such amino acids as leucine, isoleucine, and valine (the “branch-chained amino acids”) to help in muscle recovery and repair.
You can now track amino acids with a MyNetDiary Premium membership.
