Your ability to lose weight depends primarily on your body type and how it responds to different types of diets. This guide explains everything you need to know about fat protein efficient metabolism body type.

If you have an efficient metabolism, your body will use fat for energy and protein for repair and maintenance. When your body uses fat as energy, it is called ketogenic.
A person with a ketogenic metabolism has more lean muscle mass than someone who does not have this type of metabolism. This makes them look leaner than people without it. People with this type of metabolism also have less body fat because they’re using their fat to burn calories instead of just storing them in their bodies, as most people do!
The fat-protein efficient diet is a great way to lose weight, increase energy, and improve your health. The science behind it is pretty complicated, but we’ve simplified it here.
What is a Fat-Protein-Efficient Diet?
A fat-protein efficient diet (FPED) is a diet that is high in fat and protein while low in carbohydrates. This diet is meant to be consumed by people with fast metabolisms who want to lose weight.
Why would you want to try this kind of eating plan? Dr. William Wong created the FPED as a way for people with fast metabolisms to control their blood sugar levels since carbohydrates tend to raise them quickly. By emphasizing foods that aren’t easily digested or absorbed by the body—such as fats and proteins—you can avoid spikes in blood sugar levels that cause weight gain or make you hungry for longer periods than normal.
How does a fat-protein efficient diet work?

There are four basic phases of the fat-protein-efficient diet, which you can cycle through as you see fit.
- Phase 1: Eat more fats and fewer carbs. This is the traditional ketogenic diet that has become popular in recent years. Adherents to this diet believe that eating more fat leads to a healthier body and higher energy levels by increasing the production of ketones (byproducts of fat metabolism), which they claim help lower inflammation.
- Phase 2: Eat more protein and fewer carbs. This is a modification of phase 1, where instead of focusing on eating only low-carb foods, you focus on eating high-quality sources of protein—like grass-fed beef or wild fish—and eliminating processed foods from your diet altogether. Many people have found success with this method because it allows them to eat more meat without gaining weight (because the meat tends to be high in protein) while still feeling satisfied at mealtime due to its satiating effect (protein takes longer than carbohydrates or fat before it gets digested).
- Phase 3: Eat more fat while adding some carbs back into your diet to be used as fuel instead of being stored away as fat cells!
What is fat protein efficient metabolism?
The fat-protein-efficient metabolism is a diet designed to help you lose weight. It’s based on the idea that your body comprises three metabolic types, each with different caloric needs. The first type is “fat protein efficient,” which means that this person can eat fewer calories and still maintain weight. This type tends to burn more stored body fat while they sleep, thanks to their increased ability to process food into energy efficiently.
What Are the Metabolic Types?
In addition to the two metabolic types, each person has a “metabolic age.” This is determined by the average number of calories you burn per day. If your metabolic age is lower than your actual age, you’re more efficient at processing food—in other words, your body burns calories more quickly and efficiently.
When it comes to metabolism, there are also three different kinds of calories:
- Proteins: Proteins take longer to be broken down by your body and release their energy over time. When you eat protein-rich foods such as chicken breast or fish fillet with broccoli, for example, they’ll release energy slowly throughout the day rather than all at once like a carb-heavy meal would do—which is why it’s important to eat balanced meals with both carbs and protein if you want something that will keep cravings at bay!
- Carbohydrates (or starches) quickly break down into sugar (glucose) to provide energy for bodily functions like breathing and thinking.
What is the metabolic type diet?

The Metabolic Type Diet is a diet based on your metabolic type, determined by your genetic makeup and lifestyle. There’s no one-size-fits-all dieting solution, so it makes sense that we’d want to eat in a way that fits our biochemistry.
The three metabolic types are:
Fat Protein Efficient (FPS) – Fat-burning metabolism
The Fat Type (12% of the population)—this person burns fat for energy first and foremost. They have trouble gaining weight because they burn calories so quickly!
This is the ideal type of metabolism, and it’s what you want to have. FPS people do well on a low-carb diet because they’re naturally insulin-sensitive and can turn fat into fuel easily. In other words, they can use carbs as energy without storing them as fat. If you have an FPS metabolism, your body will burn more calories throughout the day—even while you sleep! The calories not burned off during digestion will be stored as glycogen in your muscles and liver. You’ll also produce fewer free radicals and less oxidative stress because fewer carbohydrates are available for them to feed on in the presence of antioxidants.
This type of metabolism burns mostly fat with some carbs (about 10 to 15 percent). It’s also called ketogenic or ketone-burning metabolism because it produces ketones, which are made up of molecules that result when your body breaks down fat for energy instead of glucose from carbohydrates.
Carbohydrate Sensitive (CS) – Carb-burning metabolism
The Carbohydrate Type (68% of the population)—this person burns carbohydrates for energy first and foremost, before fat or protein.
These people will stay lean with a high-carb diet but gain weight easily on a low-carb one. CS individuals tend to do better with exercise because it helps them burn excess glucose rather than store it as body fat.
This is the most common type of metabolism, and it burns primarily carbs (about 60 to 65 percent of total calories) with some fat. Because this kind of metabolism burns so many carbs, it’s also called carb-burning metabolism.
Balanced metabolism
The Protein Type (20% of the population) — this person burns protein for energy first and foremost, before carbohydrates or fat.
A balanced metabolism burns a mix of carbs and fats (about 40 to 45 percent each).

Fat protein efficient body type.
This type of metabolism is also known as a fat-burning metabolism, and it’s a slow one. If you have this type of metabolism, you will find it easier to lose weight than someone with a fast or normal metabolic rate.
Increased energy expenditure is characterized by an increase in energy expenditure due to the following factors:
- Insulin sensitivity
- Increased frequency and strength of muscle contraction (via regular exercise)
- Reduced calorie intake
Carbohydrate protein efficient metabolism
Carbohydrate protein efficient metabolism is a metabolism type that is characterized by a high level of protein and carbohydrate metabolism but low-fat metabolism. It is characterized by the following:
- With a low body fat percentage
- A low body weight
- A fast metabolism
Carbohydrate efficient Metabolism
Carbohydrate-efficient metabolism is the most common type of metabolism, and it’s also the least efficient. People who have carbohydrate-efficient metabolisms are often overweight or even obese. This is because their bodies have trouble regulating blood sugar.
Because carbohydrate-efficient metabolisms have so much difficulty controlling blood sugar levels, they’re also more likely to gain weight than other types of metabolisms. The reason for this has a lot to do with how carbohydrates are processed in the body; in particular, how quickly they’re broken down into glucose (blood sugar) and used as fuel by the cells in your body.
Eating for your metabolic type

- By knowing which type you are, you can learn how to eat and when to lose weight.
- You probably have a carbohydrate protein-efficient metabolism if your parents were thin, but you have the genes from both sides of your family. Or if your mom was skinny and your dad was heavy. Or vice versa.
- You might be a carbohydrate-efficient metabolic type if your mom was very skinny but also had diabetes or high blood pressure. Or if one of your grandmothers had diabetes or heart disease at a young age (50s or 60s),
- If neither parent has ever been overweight, no one in your family will likely become overweight!
What is the fat protein efficient body type?
There are three metabolic types: the lipotropic (fat-burning) type, the ketonic (ketone-producing) type, and the mixed type. Your genetic makeup determines your metabolic type. The fat protein efficient body is a specific body type with a high percentage of lean muscle mass. This means that your body composition contains more protein than fat but retains some of its ability to burn stored fat for energy.
What really matters when it comes to dieting? You might think it’s calories in versus calories out—that if you eat fewer calories than you burn through exercise or daily activity, then you’ll lose weight easily and vice versa; but according to numerous studies on metabolism—and especially those conducted over long periods—this isn’t necessarily true!
What’s the benefit of eating for your metabolic type?

- You will lose weight.
- You will feel better.
- You will have more energy.
- You will have more mental focus.
- You will have better sleep.
- You will have more muscle and endurance, which means you can do things you couldn’t do before (like run for a bus or lift heavy things) without feeling exhausted or sore afterward!
- Your digestion system will work better, so your body has less waste and fewer toxins in the bloodstream that make it hard for your cells to work properly (this includes both food-based toxins like pesticides from conventionally grown produce and environmental toxins from pollution). That’s why people who eat well and exercise regularly tend to live longer: not only because their metabolisms stay fast, so they don’t gain weight easily; but also because their bodies can cleanse themselves of toxic substances that build up over time and cause damage on a cellular level—especially when we’re exposed daily through our skin contact to polluted air filled with harmful chemicals like carbon monoxide released by fossil fuels.
Are there any cons to eating for your metabolic type?
So, what are the cons of eating for your metabolic type?
Eating for your metabolic type can be difficult if you have:
- A busy schedule.
- A family. For example, I try to cook at home as much as possible and ensure that our meals are balanced with proteins and healthy fats. Still, sometimes my kids don’t want chicken breast, salmon, or any other kind of fish—they want something like hamburgers, pizza, or Chinese food (which is pretty bad for them). And sometimes it just makes sense financially to go out instead of preparing food at home since we have three family members who need their meals prepared every time we eat. So when these situations arise, it can be hard for me because I’m trying my best to not only eat well but also buy organic products from the grocery store on top of it all!
How to Make a Fat Protein Efficient Diet Healthy
If you want to make your fat-protein efficient diet healthy, it’s important to eat various foods. This will help ensure you get the right nutrients and vitamins for optimal health.
While on your weight loss journey, remember to avoid processed foods as much as possible. If food is highly processed or has an ingredient list that reads like an encyclopedia (e.g., high fructose corn syrup), chances are it’s not very good for you.
In addition to eating healthy animal-based proteins like eggs and meat, you should also try incorporating plant-based proteins into your diets, such as soybeans or lentils, into soups and stews for extra flavor!
What Foods to Eat on a Healthy Fat Protein Efficient Diet
- Eat a wide variety of foods. Healthy fats, protein sources, carbohydrates, and vegetables are all important components of an HFPE diet. It’s important to know that each food type has its unique nutrient makeup—for example, some nuts contain more omega-3 fatty acids than others. It’s also great for your body if you eat a large variety of macronutrients (proteins, carbs, and fats), so try not to stick with just one food group or type of macronutrient!
- Variety is the key. Try not to get stuck in a rut by eating the same types of proteins daily; instead, mix it up so that your body gets all the nutrients it needs from different sources daily. If you’re looking for more protein options outside meat products such as poultry or fish (which are already great choices), consider other options such as beans, legumes, tofu; quinoa; eggs; nuts, and seeds—these can be added into dishes like salads, which makes them easier for people who may not have time during their busy schedules to prepare homemade meals each night before going out.
Example of a fat protein efficient meal plan
- Breakfast: Whole-grain cereal with milk and berries
- Lunch: tuna salad, whole-grain crackers
- Snack: Apple slices with peanut butter
- Dinner: grilled chicken with broccoli (or any other vegetable)
- Dessert: A small piece of chocolate cake
Conclusion
The fat-protein efficient diet is a great way to eat healthily and lose weight. It’s easy to follow, which makes it a great option for anyone who wants to change their lifestyle but doesn’t have time or energy for complicated diet plans. The best part is that even though you only eat three meals daily, they can be delicious! You’ll never get bored with these recipes because there’s so much variety within each meal type (protein-centric, carb-rich, or low-fiber).
FAQs about Fat-Protein Efficient Metabolism
Yes, eating proteins and fats at once is perfectly fine. Just keep them balanced.
The best way to calculate macrons are based on your body weight and height. For example, if you weigh 150 pounds and stand 5’10”, you would need about 2,000 calories daily. If you were 20 years old, this would translate into 1,500 calories.
Fat Protein Efficiency is an index used to measure how efficiently a person can convert dietary fats into muscle mass. The higher the number, the more efficiently the body converts fat into lean tissue.
Fat Protein Efficient Type Metabolism is a metabolic process where there is an increased conversion of fats into energy for use by the body. More calories will be burned than if only carbohydrates are used for fuel.
The Protein Efficient Body Type Diet is an eating plan designed for people looking to lose weight quickly while also improving their health.
The four main metabolic types are: slow metabolizers, fast metabolizers, intermediate metabolizers, and ultrarapid metabolizers.
The foods with high protein are chicken breast, turkey breast, tuna fish, salmon, eggs, milk, beans, nuts, lentils, soybeans, tofu, cheese, yogurt, and cottage cheese.
A metabolic diet is a way of eating which helps people lose weight by altering their metabolism. The idea behind this diet is to eat foods high in protein and fat while reducing carbohydrates.
