Not just protein, you need a high-protein diet to lose weight. Studies have confirmed that 0.8 g protein per kg body weight just maintains normal body functions (1). To shed pounds and tone up, you need an extra dose of protein. So, how does a high-protein diet aid weight loss? What foods to eat? Are there any side effects? Scroll down to find out.

In This Post, You Will Know…

How Does A High-Protein Diet Aid Weight Loss?

High-protein diets like Paleo, Dukan, South Beach, and Atkins aid weight loss by acting as a catalyst to switch the body to the fat burning mode. It happens in the following ways:

  • Boosts Metabolism

A slow, sluggish metabolism can prevent your body from burning fat and using it as energy. This ultimately leads to obesity and metabolic disorder. A diet rich in protein helps kick-start your metabolism.

Several studies have confirmed that people who load up on protein burn more calories and lose more weight as compared to those on a low-protein diet (2), (3), (4).

  • Increases Satiety

If you feel hungry all the time, it is because you do not include the right amount of protein in your diet. Protein is a macronutrient, just like carbs and fats. It is present in our muscles, hormones, enzymes, bone, hair, and cells. Increasing the amount of protein in your diet increases satiety, and you will feel full for a long duration.

Scientists have found that a high-protein diet increases the secretion of PPY and GLP-1, the appetite suppressing hormones, and reduces the secretion of ghrelin, the hunger hormone (5), (6).

A high-protein diet also decreases caloric intake (as you will be too full to consume more calories) and increases the thermic effect of food (7), (8).

  • Builds Lean Muscle

Muscles are made of protein. Hence, anyone interested in building muscle or becoming toned loads up on protein. Muscles are also where you find the most number of mitochondria. Mitochondria are cell organelles where metabolism (conversion of glucose or sugar to a usable form of energy) takes place. More the number of mitochondria, more the chances of burning fat.

As you age, muscle loss sets in. With muscle loss, you also lose mitochondria – resulting in slow metabolism. Research studies have confirmed that a high-protein diet prevents muscle loss, increases muscle tone, and prevents weight regain (9), (10).

So, a high-protein diet can clearly be a good way to start shedding the extra flab. But how much protein should you consume per day? Find out in the following section.

How Much Protein Do You Need To Lose Weight?

Scientific research findings suggest that you need to consume more than the Required Daily Intake (RDI) of 0.8 g protein per kg body weight to lose weight (1). Your protein intake is also directly proportional to your physical activity. The more you workout, the more protein you need to prevent muscle loss and build lean muscle mass (1).

Talk to your dietitian to get your customized daily protein intake amount. Your height, current weight, weight loss goal, activity level, genetics, and medical conditions must be taken into account before deciding how much extra protein you should consume per day to lose weight.

Once you know how many grams of protein you may consume per day, make a list of high-protein foods that will help you achieve that goal. Here are the best high-protein foods you can include in your grocery list. Take a look.

Plain egg whites or even whole eggs help you gain muscle mass and improve your strength. A University of Illinois at Urbana-Champaign study concludes that consuming 3 eggs daily helps increase your muscle mass. (11).

How To Consume Eggs

You may have them boiled, scrambled, soft boiled, or as omelet or frittata.

8. Fish

Fish like salmon, tuna, mackerel, carp, haddock, and basa are rich in protein. They are also great sources of omega-3 fatty acids. Omega-3 fatty acids help cure inflammation, boost immunity, and also may prevent the onset of certain types of cancer (12), (13). They are essential for many body functions and help you gain muscle due to the presence of essential amino acids (14). You can consume nuts like camu camu as these contain all the eight amino acids.

How To Consume Fish

Consume grilled, poached, and curried fish. If you like fried fish, shallow fry it in olive oil.

9. Soy Milk

You must have noticed that this diet chart does not include protein bars and powders. That’s because of the following reason.

Back To TOC

Should You Consume Protein Bars And Powders?

You may consume protein bars and powders if:

  • You do vigorous workout every day.
  • You do not get enough protein from whole foods.
  • You are always on the go and do not have the time to sit and eat a meal made of whole food sources of protein.
  • Your dietitian or doctor has recommended taking protein powder.

NOTE: Avoid eating protein bars available in the market as they contain other forms of low-calorie sugar that are harmful. Make your own protein bars or bombs using flaxseeds, melon seeds, jaggery, nuts, sesame seeds, honey, and granola.

To follow a diet that is high in protein, you must workout. If you don’t, the protein you consume will get converted to sugar (gluconeogenesis) and get stored in your body as fat. Here’s an exercise routine that you may follow.
