Appetite And Energy Metabolism
Protein reduces appetite by increasing the levels of certain peptides, such as glucagon-like peptide 1 .
In addition, your body needs to expend 2030% of the caloric value of protein to metabolize and store it, compared to 510% for carbs and just 03% for fat. In other words, the thermic effect of food is highest for protein. Whether this makes a practical difference in human beings outside of a clinical setting is a much-debated topic, but diets high in protein have also been shown to mitigate the decline in resting energy expenditure caused by calorie-restricted diets, perhaps because protein promotes muscle retention.
A trial randomized 130 overweight people between a high-protein group and a low-protein group. Each day, the high-protein group consumed 1.6 grams of protein per kilogram of body weight and the low-protein group 0.8 g/kg . The trials 500 kcal daily deficit led to a weight loss of 9.911.2% over a year with no difference between groups, but the high-protein group lost more fat than the low-protein group , and men more fat than women.
Of course, adding exercise can help. In a 16-week trial, 90 overweight or obese women followed the same exercise regimen and were randomized to three groups: high protein, high dairy adequate protein, medium dairy and adequate protein, low dairy. The first group experienced greater fat loss and muscle gains.
What Is The Thermogenic Effect Of Protein
It takes energy to digest your food – commonly referred to as the thermic effect of food . And as it turns out, each macro requires a different amount of energy to digest.
Protein is thought to be the most thermogenic of all the macros – causing a small spike in metabolism to digest protein foods compared to fat and carbs . And it is commonly believed that eating more protein overall may lead to tiny increases in your daily metabolism and overall energy expenditure.
TEF only accounts for 10% of your total energy expenditure, but because dieting is associated with decreases in metabolism over time – due to prolonged caloric restriction and decreases in mass, this minor effect on metabolism may be worth considering .
How To Choose A Healthy Protein Powder
Be sure to read the packaging before purchasing. White warns that because protein powders are considered a dietary supplement, they do not need FDA approval before hitting the marketso its crucial to scan the label. Gradney suggests aiming for a lower-calorie, higher-protein pick, so aim for a powder that contains 150 calories or less and around 20 grams of protein per serving.
Bottom line: Remember to keep your goals in mindand that the number on the scale doesnt necessarily paint the whole picture. If youre using protein as part of your weight-loss journey, just be sure to account for the added calories throughout your day and adjust your remaining meals accordingly.

How Does Protein Help With Weight Loss
In decades past, low fat and low calorie diets were often recommended for anyone who wanted to lose weight. More recently, however, the advice shifted. Recognizing that these diets were often unsustainable, nutrition experts began recommending diets that were higher in protein and dropped the focus on calories and fat.
A high protein diet has been shown to help people lose weight and belly fat while increasing both muscle mass and strength. There are several reasons why protein is considered the most important nutrient for weight loss.
First, protein can help to change the levels of some of the hormones that regulate your weight. It has been shown to increase the levels of the appetite reducing hormones GLP-1, peptide YY and cholecystokinin while simultaneously reducing the hunger hormone ghrelin. These hormones send signals to your brain for it to determine when and how much to eat. When you replace the carbohydrates and unhealthy fats in your diet with protein, you will experience less hunger and typically lose weight as a result.
Second, your body must burn calories in order to digest and metabolize protein. This is known as the thermic effect of food. Compared to the thermic effect of carbs and fat , protein has a much higher thermic effect of 20 to 30%. The end result is that when you focus on protein-rich foods, your body will burn more calories automatically.
Protein Helps You Feel Full Longer
One of the biggest things that impedes weight loss is hunger.
People are far less likely to stick with a nutrition or diet plan if they experience high levels of hunger.
Protein is the most satiating of all the macronutrients .
Several different lines of research have all pointed to the same thing: higher protein intakes tend to provide more satiety and less hunger.
For example, in one study, high protein snacks allowed people to go longer between eating and also caused them to eat less at subsequent meals .
Another study showed that including protein into a glass of water decreased hunger compared to water alone .
Depending on the source of protein, there does appear to be minor differences in the exact amount of satiety that protein provides, however these differences are minor and dont really make a meaningful impact for most people .
Currently, there is no consensus on the optimal level of daily protein intake in ones diet with regard to stay full. However, roughly 1.8 – 2.9 grams of protein per kilogram daily appears to provide substantial benefit on satiety .
Should You Eat Breakfast
In the past, skipping breakfast has been associated with weight gain.
We now have good evidence showing that recommendations to eat or skip breakfast have no effect on weight gain or loss. You can read more about that in this article .
However, eating breakfast may be a good idea for other reasons. For example, it may improve mental performance in school children, teenagers and certain patient groups .
This may also depend on the quality of the breakfast. Even if the stereotypical breakfast has no effect on weight, a breakfast that is high in weight loss friendly protein may have different effects.
Recommendations to eat or skip breakfast have no effect on weight. However, the same may not apply to a high-protein breakfast.
Protein Can Help Satisfy Your Hunger
While it’s essential to remember carbohydrates are not the enemy, it’s also true that some are better than others. When trying to lose weight, many people cut back on carbs, particularly those in the form of desserts or other sweet treats. Though this is positive, it requires our bodies to adjust to a new way of digesting, explains Keith-Thomas Ayoob, EdD, RD, FAND, an associate clinical professor emeritus at the Albert Einstein College of Medicine. In other words: you may get hungrier faster, but you can fight against this by upping your protein intake. How come? Protein takes longer to digest than carbs, so it stays in your stomach longer, keeping you feeling full.
“Hunger isn’t the only reason people eat, of course, but it’s a major one, and when you’re on a weight loss diet, you’re eating fewer calories than you’re used to, so it’s common to feel hungry,” says Ayoob. “The extra protein can help out here.”

Eat Your Protein First
When eating a meal, eat the protein source first, especially before you get to the starches.
Protein increases the production of peptide YY , a gut hormone that makes you feel full and satisfied .
In addition, a high protein intake decreases levels of ghrelin, the hunger hormone, and increases your metabolic rate after eating and during sleep .
Whats more, eating protein first can help keep your blood sugar and insulin levels from rising too high after a meal.
In one small study, people with type 2 diabetes were served identical meals on different days. Blood sugar and insulin rose significantly less when they consumed protein and vegetables before eating high carb foods, compared with when the order was reversed .
Eating protein first at meals can help you feel full and keep your blood sugar and insulin levels from rising too high.
Can Protein Help You Lose Weight
Increasing your protein intake beyond that might be helpful for those looking to shed some pounds as long as it does not mean excess calories. “It can help with weight in that it can balance satiety, or our fullness factor,” says Melissa Majumdar, M.S., a registered dietitian at Emory University Hospital and a spokesperson for the Academy of Nutrition and Dietetics. While calorie restriction is typically required for weight loss, loading up on protein-rich foods can help you feel satisfied even within those caloric constraints.
This relates to hormones, which can trigger the body’s cues for both hunger and fullness. “When we eat a meal and it gets into our small intestines, we release hormones to tell us to stop eatingand protein is the best at ,” explains Fujioka. To be specific, protein is better as a satiety signal than its fellow macronutrients, fat and carbohydrates.
Moreover, that fullness factor isn’t fleeting. “Studies show that it’s both with a single mealso if your meal contained protein, then it would create more fullnessbut also a 24-hour period,” says Majumdar. “So, over the course of the day, if there was more protein incorporated, that can control hunger better.”
Then there’s the fact that protein is a key player for creating muscle mass. “Whenever we lose weight, we naturally lose some of our lean muscle mass, and protein can help preserve that,” says Majumdar.

How Much Protein Should I Be Eating For Weight Loss
Experts advise consuming between 0.5 grams and 1.0 grams of protein per pound of your body weight. That’s 70 grams to 140 grams a day for a 140-pound woman. Skew on the high end if you’re very active, and on the low end if you’re trying to lose weight. If both apply, shoot for an amount somewhere in the middlearound 130 grams.
Aim to get at least 30 of those grams at breakfast, says Donald Layman, PhD, a professor emeritus of nutrition at the University of Illinois. After fasting all night, your body is running on empty and may start drawing on muscle tissue for fuel if you don’t replenish its protein stores first thing in the a.m. Plus, studies have found that protein-rich breakfasts can help regulate your appetite all day.
But not all proteins are created equal. While nuts, whole grains, and veggies technically count, they don’t contain all nine of the amino acids your body needs in order to build lean muscle. Those that doknown as complete proteinsare typically found in animal products. Your best bets are skinless white chicken or turkey, seafood, low-fat dairy, pork tenderloin, and lean beef. All of these foods have just one to three grams of fat per 50-calorie serving.
Developing A Workout Routine
While drinking protein shakes can certainly help you to meet your goals of losing weight, just incorporating shakes into your diet is not enoughexercise is key to losing weight. Because you must burn more calories than you consume in order to drop pounds, you may want to focus on high-intensity workouts. Cardio is one of the best ways to burn a lot of calories quickly. Running or cycling are popular cardio workouts that will help you to work up a sweat, burn calories and strengthen other parts of your body like your core and legs.
Most people who are trying to lose weight will focus on building up muscles in their core, but your initial goal should be to burn off excess fat before trying to build the lean muscle underneath. Swimming, rowing, using the elliptical and jumping rope are other great calorie-burning workouts. As you notice your weight beginning to drop, you can start to integrate more strength-building exercises into your routine.

Protein Makes You Burn More Calories
Due to the high thermic effect and several other factors, a high protein intake tends to boost metabolism.
It makes you burn more calories around the clock, including during sleep (
This effect is particularly pronounced during overfeeding, or while eating at a caloric surplus. In one study, overfeeding with a high protein diet increased calories burned by 260 per day .
A high protein intake can make you burn 80-100 more calories per day, with one study showing an increase of 260 calories during overfeeding.
How Can I Make Sure I’m Eating A Healthy Amount Of Protein And Not Going Overboard
Okay so, now that you know the risks and symptoms associated with eating too much protein, its time to focus on how you can keep protein in your daily diet without going overboard. Here are some tips for eating protein in a healthy way, according to dietitians.

Top Your Food With Chopped Almonds
Almonds are incredibly healthy.
Theyre high in magnesium, fiber, and heart-healthy monounsaturated fat, yet low in digestible carbs.
Almonds also contain 6 grams of protein in a 1-ounce serving, which makes them a better source of protein than most nuts .
And although a serving of almonds contains around 170 calories, studies have shown that your body absorbs only about 133 of those calories because some of the fat isnt digested .
So sprinkle a few tablespoons of chopped almonds over yogurt, cottage cheese, salads, or oatmeal to increase your protein intake and add a bit of flavor and crunch.
Almonds are high in several nutrients and can boost the protein content of a meal or snack.

Beans Lentils Peas & Soy
Legumes beans, lentils, peas, seeds, and soy are a good source of protein and provide other essential nutrients. Yes, most are higher in carbs than the other foods on this list. However, theyre also high in fiber. Plus, as an excellent source of plant-based protein, legumes are perfect for vegetarian and vegan weight-loss diets.
One review of 21 trials found that people who included beans, lentils, and other legumes in their diet lost a small amount of weight without deliberately restricting calories.16
While soy is considered a complete protein, beans and legumes are low in one or more of the essential amino acids that you need to eat to stay healthy.18 The good news is, combining different plant proteins, such as beans and nuts, can provide adequate amounts of all the essential amino acids your body needs.19
Plant protein powder supplements are processed, so they lack the fiber found in whole foods. However, they are a good option for getting more protein with fewer carbs. For this reason, you may want to consider occasionally including plant protein powders if youre a vegetarian or vegan who eats keto or low carb.
Protein percentage range: 80% to 26%
Animal Versus Plant Protein
Is all protein the same? No, not really.
Animal proteins are considered complete sources of protein meaning they supply all nine essential amino acids whereas all plant sources aside from soy are incomplete.30 This doesnt mean you cant get all essential amino acids from plant sources. It simply means you will need to combine different sources, such as beans with nuts or whole grains.
Your body also absorbs animal proteins much better than most plant proteins, meaning you can eat less for the same effective amount of protein. Again, that doesnt mean you cant get adequate protein from plant sources. But it does mean you may need to increase your intake goals by 20% or more.31
Lastly, plant sources of protein tend to be higher in carbohydrates than animal sources. If you follow a very low-carb or keto diet, this can make meeting all your goals challenging.
Soy is unique among plant proteins since it is a complete protein and appears to have similar bioavailability, muscle-building effects, and weight loss benefits as animal proteins.32
However, aside from soy, evidence suggests animal protein may be more beneficial for strength and muscle maintenance and may provide a better source of micronutrients, especially from red meat. 33

Protein Preserves Lean Body Mass
In addition, protein has another benefit on weight loss: it helps preserve lean body mass during periods of caloric restriction.
One study compared the effect of low protein intake to high protein intake on lean body mass over a short term caloric deficit. On average, the low protein group lost about 1.6 kilograms of muscle mass while the high protein group only lost 0.3 kg of muscle mass .
Another similar study compared 0.8 g/kg per day against 1.6 g/kg per day and 2.4 g/kg per day and found that the two higher intakes spared more lean body mass than the 0.8 g/kg per day diet. They also found that there was no real benefit to 2.4 g/kg per day over 1.6 g/kg per day .
Currently, most evidence suggests that ~1.6 grams of protein per kilogram, or .73 grams of protein per pound is a recommended daily target for protein intake to spare lean body mass loss during periods of weight loss.
