Oxidative Priority And Thermic Effect Of Food
The table below shows:
- the order in which the different components of our food are used in your body ,
- what they are used for,
- their storage capacity, and
- their thermic effect.
Because we have negligible storage capacity for them in our bloodstream, alcohol and ketones are used for energy first, followed by excess protein, then by carbs and fat.
If you have plenty of fat and carbs available, your body may even use those easier energy sources first and excrete some protein in the urine because its harder to convert to ATP.
Although carbs and protein can be converted to fat, it is usually the dietary fat that is stored on your body because it is last in line to be burned. Fat also requires less insulin to hold in storage, so it can easily be stored easily.
The thermic effect of food is the amount of energy that is lost to heat in converting that particular food to usable energy in your body . Protein has a more complex chemical structure than carbs or fat, so it takes more energy to break the carbon bonds to unlock the energy to be used in your body. This thermic effect of food contributes to keeping you warm, but some people can even experience meat sweats when they eat a lot of protein.
Its important to note that there is a range of thermic effect of protein-containing foods. A protein powder that is easy to digest may have a thermic effect of 20%, while a piece of raw liver or kidney which is more complex may incur 35% losses in conversion to usable energy.
How Much Protein Per Day To Lose Weight
If you want to lose weight, aim for a daily protein intake between 1.6 and 2.2 grams of protein per kilogram of body weight . Athletes and heavy exercisers should consume 2.2-3.4 grams of protein per kilogram if aiming for weight loss.
My practical recommendation to people is that if you carry a BMI of over 30 or a body fat percentage above 25-30% it makes more sense to base your protein recommendations off of your goal weight.

- Afternoon snack: Plain Greek yogurt with ½ cup of berries
- Dinner: 6 oz. grilled salmon with roasted or sautéed veggies

How Much Protein Is Optimal
The DRI for protein is only 46 and 56 grams for the average woman and man, respectively.
This amount may be enough to prevent deficiency, but it is far from optimal if you are trying to lose weight .
Most of the studies on protein and weight loss expressed protein intake as a percentage of calories.
According to these studies, aiming for protein at 30% of calories seems to be very effective for weight loss.
You can find the number of grams by multiplying your calorie intake by 0.075. For example, on a 2000 calorie diet you would eat 2000 * 0.075 = 150 grams of protein.
You can also aim for a certain number based on your weight. For example, aiming for 0.7-1 gram of protein per pound of lean mass is a common recommendation .
It is best to spread your protein intake throughout the day by eating protein with every meal.
Keep in mind that these numbers dont need to be exact, anything in the range of 25-35% of calories should be effective.
More details in this article: How Much Protein Should You Eat Per Day?
In order to lose weight, aiming for 25-35% of calories as protein may be optimal. 30% of calories amounts to 150 grams of protein on a 2000 calorie diet.
Protein Cuts Cravings And Reduces Desire For Late
Cravings are the dieters worst enemy.
They are one of the biggest reasons why people tend to fail on their diets.
Another major problem is late-night snacking. Many people who have a tendency to gain weight get cravings at night, so they snack in the evening. These calories are added on top of all the calories they ate during the day.
Interestingly, protein can have a powerful effect on both cravings and the desire to snack at night.
This graph is from a study comparing a high-protein diet and a normal-protein diet in overweight men (
The high-protein group is the blue bar, while the normal-protein group is the red bar.
In this study, protein at 25% of calories reduced cravings by 60% and cut the desire for late-night snacking by half!
Breakfast may be the most important meal to load up on the protein. In one study in teenage girls, a high-protein breakfast significantly reduced cravings .
Eating more protein can lead to major reductions in cravings and the desire to snack late at night. These changes should make it much easier to stick to a healthy diet.

Scientific Research On Whey
Whey protein supplementation has a lot of potential to help with weight loss, based on scientific research. For instance:
- In a placebo-controlled study on whey protein and dieting, one group of dieters was given a whey protein supplement, and the other group was given a placebo. The whey protein group lost more fat than the control group, and kept more muscle mass.
- Another study in 2006 found that adding 60 grams of whey protein per day, in comparison to 60 grams of soy protein or 60 grams of carbohydrate, led to decreases in body fat and weight after 6 months.

Protein Reduces Cravings And The Desire To Snack At Night
Cravings are one of the main reasons why people fail on a diet.
Another big issue is nighttime snacking. A lot of people who are genetically more disposed to put on weight have cravings at night, which makes them take snacks. These are additional calories to those consumed during the day.
Fortunately, protein has a positive impact on both cravings and desire for late-night snacking. Below is a graph from a study that compared a protein-rich diet to a normal-protein diet in overweight men.
The blue bar represents the high-protein group, while the red bar stands for the normal-protein group.According to this study, protein at 25% of the total calories decreased cravings by 60% and lowered the desire to snack at night by 50%!
Breakfast might be the best meal to load up on high-quality protein. A study conducted on teenage girls found that a high-protein breakfast decreased cravings to a large extent.
Reduces Cravings And Desire For Late
A food craving is different from normal hunger.
It is not just about your body needing energy or nutrients but your brain needing a reward .
Yet, cravings can be incredibly hard to control. The best way to overcome them may be to prevent them from occurring in the first place.
One of the best prevention methods is to increase your protein intake.
One study in overweight men showed that increasing protein to 25% of calories reduced cravings by 60% and the desire to snack at night by half .
Likewise, a study in overweight adolescent girls found that eating a high-protein breakfast reduced cravings and late-night snacking.
This may be mediated by an improvement in the function of dopamine, one of the main brain hormones involved in cravings and addiction (
more protein may reduce cravings and desire for late-night snacking. Merely having a high-protein breakfast may have a powerful effect.

Protein Carbs And Weight Loss
How might a high-protein, low-carb diet lead to weight loss more quickly than a low-fat, high-carb diet, at least in the short run?
- First, chicken, beef, fish, beans, and other high-protein foods move more slowly from the stomach to the intestine. Slower stomach emptying means you feel full for longer and get hungrier later.
- Second, proteins gentle, steady effect on blood sugar prevents the sharp blood sugar dips that often occur after eating rapidly digested carbohydrate, like white bread or baked potato.
- Third, the body uses more calories to digest protein than it does to digest fat or carbohydrate.
- Eating higher amounts of protein also seems to help dieters preserve lean muscle during weight loss, and this, too, can help boost the amount of energy they burn.
If you do decide to follow a higher-protein, lower-carbohydrate eating plan, choose the healthiest sources of protein possible. Remember that limiting red meat and avoiding processed meatand choosing healthier high-protein foods in their place, such as fish, chicken, beans, or nutswill help the heart and the waistline.

Does Protein Help You Lose Weight
Weight loss is an extremely common fitness goal, especially as the weather starts to get colder entering into the final stretch of the year. More time indoors and shorter days generally mean people get less active, not to mention the increased availability of holiday snacks and desserts! Between 2013 and 2016, the CDC reported that nearly half of all American adults attempted to lose weight at some point in the last 12 months.
Yet despite how prevalent the desire to lose weight is, there are many misconceptions about what it takes to shed pounds. Some people engage in endless amounts of cardio while neglecting strength training. Others increase their activity level but fail to properly manage their diet.
In reality, losing weight requires a holistic approach. You need to reduce your total calories consumed, increase your activity level, and make sure youre eating the kinds of foods that will keep you energized throughout the day. If you want to lose weight efficiently, protein should play a significant role in your diet. Not only will it help you control your appetite and keep hunger in check, increasing your protein intake can also help you improve muscle mass, which can be important for achieving and sustaining weight loss.
It Can Help You Balance Hormones
If you’re struggling to see a difference on the scale, there could be many aspects at play. One of the most significantand yet, often overlookedare our hormones. When these are off-kilter, it can impact our mood and our ability to lose weight.
“An imbalance in your hormone levels can affect hunger and fat storage,” says nutritionist and celebrity chef Serena Poon. “A protein-rich diet has been shown to increase the activity of leptin, a hormone that regulates body weight, fat mass, and appetite.”
Plus, she explains high-protein meals have also been shown to suppress another hormone, ghrelin , which increases feelings of satiety.
Just How Important Is Protein In Your Diet
A constant battle I seem to have with my clients is getting them to eat more protein! I tend to prescribe around 1.2 grams of protein per lb of lean muscle mass which, I know is a lot! This tends to be around 120g-180g of protein a day! BUT protein is so important! The health effects of fat and carbs are controversial and often debated in health circles, with popular restriction diets that include high fat, low carb or no carb. Yet, independent of where you stand, almost everyone agrees that protein is important.
Numerous studies suggest that a high-protein diet has major benefits for weight loss, muscle gain and metabolic health. Therefore, in this blog I will discuss 8 science-based reasons that you should eat more protein.
- Reduces Appetite and Hunger Levels
- Increases Muscle Mass and Strength
Muscle is made primarily of protein. High protein intake can help you gain muscle mass and strength while reducing muscle loss during weight loss. Protein is the building block of your muscles. Therefore, eating adequate amounts of protein helps you maintain your muscle mass and promotes muscle growth when you do strength training. Numerous studies show that eating plenty of protein can help increase muscle mass and strength. If youre physically active, lifting weights, or trying to gain muscle, you need to make sure youre getting enough protein.

How Much Weight Can I Lose On A High
A high-protein diet can be great for weight loss since it naturally allows you to cut back on other items, like swapping in a salmon dish instead of pasta for dinner, according to Brigitte Zeitlin, a registered dietitian and owner of BZ Nutrition in New York City.
The amount of weight you may lose, though, will depend on various factors, including age, gender, what your initial diet looks like, and which types of protein youre adding to your diet .
One thing to keep in mind is that bodies absorb protein better when it comes with some carbohydrates, so pair your proteins with a vegetable or fruit to get the most out of it, says Zeitlin.

Quarantine 15 How Protein Can Help With Weight Loss
Are you looking to lose some of the weight you put on during quarantine? One habit that can help you reach your goals is to eat foods that are high in protein.
Protein metabolizes slowly in your body. That means your body uses it for energy at a steadier rate. As a result, protein helps you to feel full longer.
Protein comes in many forms, including meat, fish, poultry, dairy, beans and protein powders and shakes. Learn more about sources of protein and how you can integrate this important nutrient into a weight-loss plan.

Weight Loss And Body Composition
Not surprisingly, proteins ability to suppress appetite, promote fullness and increase metabolism can help you lose weight.
Several high-quality studies have found that increasing protein intake promotes weight and fat loss .
In a six-month diet study including 65 overweight and obese women, the high-protein group lost an average of 43% more fat than the high-carb group. Whats more, 35% of women in the high-protein group lost at least 22 pounds .
Typically, when you reduce your calorie intake, your metabolism slows down. This is partly due to muscle loss.
However, research suggests that a higher protein intake can help protect against muscle loss and keep your metabolic rate up .
In one large review of 24 studies that included over 1,000 people, high-protein diets were found to be more effective than standard-protein diets for losing weight, preserving muscle mass and preventing metabolic slowdown during weight loss .
Importantly, standard or high-protein diets can be effective for everyone.
But interestingly, one European study concluded that based on different gene types, high-protein diets would be especially effective for weight loss and maintenance in 67% of the population .
The ability of high-protein diets to decrease hunger, increase feelings of fullness, boost metabolic rate and protect muscle makes them effective for losing weight and improving body composition.
