The benefits of eating protein for healthy and achievable weight loss
- 6 Minutes Read
Protein, protein, protein seems to be everywhere; are there additional 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 that make up 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 a healthy body.
You can meet your daily protein needs from both plant and animal foods. Animal proteins (meat, fish, poultry, game, eggs, and dairy) are "complete," meaning they provide all the essential amino acids needed to build proteins.
Some animal proteins are also high in calories due to fat content. 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 typically rich in dietary fiber, vitamins, and minerals. Yet, they are low in one or more essential amino acids that make up a complete protein. Eat a variety of plant proteins throughout the day to ensure that you get enough of each essential amino acid. Also, eating small amounts of animal protein with plant protein makes a complete protein.
Plant sources of protein are typically high in either carbs (legumes, grains) or fats (nuts and seeds). If you are looking for a healthy protein choice for weight loss and follow a plant-based diet, plan your proteins to stay within your calorie budget. If you are watching carbs, note that some plant proteins will add to your carb intake.
Since most 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.
Macronutrient | DRI: Acceptable Macronutrient Distribution Ranges | MyNetDiary Goal |
---|---|---|
Fat | 20-35% of total calories | 35% of total calories |
Carbohydrate | 45-65% of total calories | 45% of total calories |
Protein | 10-35% of total calories | 20% of total calories |
If you prefer a different macronutrient target, customize your goals with a Premium MyNetDiary membership.
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 intake higher than the RDA. Read here for more information on starting a higher protein plan.
For certain kidney and liver conditions, you may need to limit your protein intake. Talk to your doctor or dietitian about your diet and follow their specific nutrition advice.
To achieve weight-loss success, you must meet your protein needs every day. Since protein takes longer to digest than carbohydrates, you will likely stay full longer if you eat protein at each meal. When you eat enough protein and implement a consistent strength-training routine, you have a better chance of preserving muscle mass as you lose weight.
It is possible to overeat protein. Make sure not to go overboard. If you exceed your calorie budget by eating too much protein, you may gain weight.
Tip: Aim for at least 60g/day of protein while on a reduced-calorie diet.
