Whether you’re looking to reach a new PR or enhance your overall health, experts continue to show that building and maintaining muscle mass is one of the best ways to reach your goals. However, amidst the sea of conflicting information and trendy diets, finding a sustainable approach can feel overwhelming. So, how can you separate fact from fiction to find what actually works?

In this article, we are diving into the science to determine the best nutrition tactics for how to lose fat and gain muscle. But before we get started, let’s first understand what body composition is and why it’s important for health. 

Understanding body composition

Whether you’re looking to improve your health span or boost your quality of life, there are many reasons why body composition matters. Let’s take a closer look at how body fat and muscle mass contribute to your overall health. 

Body fat

Adipose tissue (or body fat) is a connective tissue that is found under the skin, between internal organs, and in bone marrow. It serves as an energy store, insulator, and active organ in the endocrine system. Adipose tissue is comprised of nerve cells and blood vessels, and communicates through hormone signals with other organs, playing a crucial role in overall health [

]. 

While we need a certain amount of body fat to survive, excess body fat has been shown to contribute to health problems, such as type 2 diabetes, high blood pressure, heart disease, stroke, some cancers, metabolic syndrome, osteoarthritis, and more [

]. 

What is muscle mass? 

By definition, muscle mass refers to the size of your muscles and how much you have in your body. These muscles are integral for a diverse amount of bodily functions, such as facilitating movement and maintaining posture [

Muscle mass is a vital component for overall health and wellness, as it plays a crucial role in enhancing functional strength and overall quality of life. It also helps with body composition, reduces the likelihood of chronic diseases, aids in mobility and balance, and fosters independence in day-to-day activities, especially as you age. Furthermore, studies have also found that muscle mass may help prevent injury, increase bone density, boost metabolic rate, and help maintain overall mental well-being and cognitive function [

5 nutrition tactics for how to lose fat and gain muscle

Science indicates that you can improve your health (and body composition) by what you put on your plate. Here are 5 nutrition tactics for how to lose fat and gain muscle.

#1: Prioritize protein

Protein is an essential macronutrient that plays a vital role in strength, lean muscle mass, post-workout recovery, and satiety [

8

,

9

]. 

Numerous studies continue to show that consuming a high protein diet can boost metabolism, assist in weight loss, and improve body composition, since it decreases fat mass while preserving fat-free mass [

10

,

11

]. 

Conversely, research suggests that a protein deficiency may lead to muscle atrophy, impaired muscle growth or regrowth, and functional decline [

12

]. 

Dosing recommendations

The current RDA is 0.8 g/kg/day for all adults over 18 years of age [

13

]. However, studies also indicate that people over 65 years old can consume between 1 to 1.2 g protein/kg of body weight/day [

14

]. 

If you are an athlete or highly active individual, research shows that you may need 1.2-2.0 g/kg of body weight/day, depending on training needs and goals [

15

]. Experts also suggest that 1.2-1.7 g of protein/kg of body weight/day can be beneficial to increase muscle mass [

16

]. 

Give Smart Protein a try

While you can get protein through numerous dietary sources (like lean meat, tofu, beans, and Greek yogurt), protein powders are a popular supplement for those looking to increase their protein intake.

Elo Smart Protein

is a personalized protein powder that is designed for anyone who wants to boost recovery and enhance performance. Unlike other custom protein products, Elo Smart Protein uses your goals, health history, workout data, and dietary preferences to craft the right protein blend for you and provide specific protein dosing recommendations after every workout. 

Elo Smart Protein is also backed by the latest science to help you recover faster and get the most out of every scoop of protein powder.

#2: Eat healthy fats

Research continues to show that consuming healthy fats (like omega-3 acids, monounsaturated fats and polyunsaturated fats) benefit your heart, as they help increase

HDL “good” cholesterol

and lower

LDL “bad” cholesterol

.

While these healthy fats play a crucial role in heart health, cellular growth, inflammatory markers, and energy levels, emerging evidence shows that an increase in muscle mass could also improve the ratio of HDL to LDL [

17

,

18

]. Furthermore, some studies suggest that taking fish oil omega-3s may reduce body fat, but these effects appear to be modest, and might not apply to everyone [

19

]. 

Some dietary sources of healthy fats include vegetable oils (like olive oil and canola oil), avocados, nuts, eggs, and fatty fish such as salmon, herring, sardines and trout. 

Dosing recommendations

While the amount of fat you need per day can vary, experts recommend that fat should make up 20 - 35% of your total calories [

20

].

#3: Be mindful of calories

Watching your caloric intake plays a crucial role in achieving a balance between burning fat and preserving muscle. If you’re looking to shed excess body fat, creating a caloric deficit will prompt your body to utilize stored fat as an energy source. However, it's crucial to strike the right balance, as an extremely low calorie intake can cause fatigue, nutritional deficiencies, and even muscle loss.

If you choose to create a calorie deficiency to help shed excess fat, it’s crucial to eat enough protein and do both endurance and resistance exercises to preserve muscle mass and enhance strength [

21

]. 

Talk with a dietitian or healthcare provider to learn more about the right caloric intake for you.

#4: Get more vitamin D

Often referred to as the “sunshine vitamin”, vitamin D is an essential nutrient that is vital for calcium absorption and immune function, as well as bone and heart health [

22

]. Vitamin D also plays a crucial role in muscle growth and development. A vitamin D deficiency has been associated with decreased muscle size and strength, and interestingly, studies have found that people who took vitamin D had greater overall strength compared to those who didn’t supplement [

23

]. 

Furthermore, emerging research has found a connection between vitamin D deficiency and weight, suggesting that excess body fat may prevent vitamin D absorption [

24

]. As such, experts theorize that people with normal vitamin D levels may lose weight compared to those with lower levels, which might make vitamin D a potential option for weight loss programs [

25

,

26

]. 

However, further studies are needed before more definitive solutions can be determined.

Dosing recommendations

For vitamin D, the recommended daily allowance for men and women 19-70 years old is 600 - 800 IU, but some evidence suggests that 2,000+ IU may be beneficial for certain people [

22

].

While your body can synthesize vitamin D from the sun, you can also obtain it in foods like mushrooms, cod liver oil, fortified foods, sardines, and eggs, or in supplements like

Elo Smart Gummies

.

#5: Consider intermittent fasting

Intermittent fasting

(IF) is a dietary approach centered around eating and fasting for specific periods of time throughout the day or week. It has long been praised for its health benefits, and for good reason - research shows that IF influences hormone levels, cell repair, and metabolic health [

27

]. 

Studies also suggest that fasting may enhance the secretion of growth hormone (which can be beneficial for both fat loss and muscle gain), as well as regenerate new cells and produce metabolic changes to switch from burning glucose to fatty acids [

28

,

29

]. 

Summary

Experts continue to show that building muscle and reducing fat mass can have a dramatic impact on your health, athletic performance, and mobility. While physical activity certainly plays a role in your body composition, science suggests that what you put on your plate can also make a difference. By focusing on protein, getting enough healthy fats, optimizing vitamin D levels, being mindful of your caloric intake, and experimenting with intermittent fasting, you can enhance your health, reduce fat, and improve muscle.
