Take QuizFact checked by Andrew Lenau, ISSA CPT & Sports Nutritionist
FACT CHECKEDIt's natural to want it all. As humans, we like to have our cake and eat it too. In fitness, this leads to a desire to lose fat and build muscle at the same time. Yet, the problem is whether it's even possible.
The answer lies not just in rigorous workouts but also in the kitchen, as the right dietary approach plays a pivotal role in achieving this delicate balance. Unfortunately, in this scenario, little cake is allowed. But that's okay because the results taste better than a piece of cake ever could.
In this article, we delve into body recomposition and unveil the most effective diets tailored to help you achieve the seemingly contradictory goals of fat loss and muscle gain. From unlocking the secrets of our ancestors to macronutrient manipulation, get ready to sculpt the physique you've always dreamed of.

Let's start with the big question. Is this even possible? The quick answer is yes, it is possible to lose fat and build muscle simultaneously.
In fitness circles, this process is called body recomposition, or "recomp" for short. For people new to resistance training or overweight, body recomposition is possible and highly likely with proper weight training and nutrition.
But what about trained lifters who are already in pretty good shape?
For years, this group was not in the conversation. However, a recent narrative review by Barakat and colleagues provides evidence indicating body composition is possible in trained individuals1. The review shows a multitude of studies that indicate that trained people can lose body fat and build muscle at the same time. The key is playing your cards right.
A good diet for losing fat and building muscle balances a slight calorie deficit with sufficient protein intake. To shed fat, you need to consume fewer calories than your body expends, but it's crucial to maintain a diet rich in protein to support muscle growth and repair.
I created a rating system to find the best diet for body recomposition.
Each diet is rated based on:
In this system, each diet is scored between one and ten for each category, with ten being a perfect score. Only four diets made the cut. Let's find out which are best for your body recomp goals.
Take a walk down a nutrition section in any major bookstore, and you will quickly realize there are a lot of diets. With that in mind, we have plenty of options to find the best diet to lose fat and build muscle.
The four best diets, in order from best to worst, for losing fat and building muscle at the same time are:
Any of the diets listed can work. However, some are better than others, which you'll see below as I discuss each in detail.
The #1 best diet for losing fat and building muscle at the same time is flexible dieting, a dietary approach that prioritizes overall caloric intake and macronutrient distribution rather than rigid food restrictions. Instead of focusing on specific foods, flexible dieters concentrate on daily macronutrient goals - protein, carbohydrates, and fats - tailored to their needs.
The counting macros method allows for diverse food choices, including those often considered indulgent or less traditional in conventional diets.
The key is to balance and hit the targeted macronutrient ratios while staying within the overall calorie limit. By emphasizing the importance of moderation and individual preferences, flexible dieting offers a sustainable and adaptable way to achieve fitness and nutrition goals without feeling deprived or constrained by arbitrary food rules.
Comments: Including flexible dieting on the list feels like cheating. Flexible dieting is not really a diet. It is a dieting strategy. That said, it's an approach that allows you complete control to customize your diet to the specifications you need.
Plus, with the ability to fit in some of your favorite foods, you are more likely to stick it out for the long term, which is needed to lose fat and gain muscle at the same time. Keep in mind that flexible dieting is not an excuse to fit in as many fun foods as possible.
You still need structure to be successful, but no worries, as I've got you covered. After I discuss the remaining diets, I'll provide a flexible diet meal plan you can follow.
A carb-cycling diet alternates between periods of high and low carbohydrate intake throughout the week. Rather than consistently consuming the same amount of carbs (and calories) daily, this approach tailors carbohydrate intake to match specific energy needs.
Typically used by athletes, bodybuilders, or those seeking to lose weight while preserving muscle mass, carb cycling involves higher carb intake on intense workouts to fuel energy needs and support muscle hypertrophy. On rest or low-activity days, carbohydrate intake is reduced to encourage the body to use stored fat for energy, promoting fat loss. This dynamic approach allows individuals to adapt their diet to their activity levels, promoting better energy utilization and potential improvements in body composition.
Another example of carb cycling is using refeeds. A typical way to set up a carb cycling refeed diet is to follow a standard calorie-restricted diet for five days, followed by two consecutive days with higher calories and carbohydrates. An example would be following a low-carb diet Monday through Friday, with high-carb days on the weekend. A 2020 study looking at this carb-cycling diet found it leads to similar weight loss as traditional dieting but allows you to maintain more lean body mass2.
Comments: Carb cycling diets are great for body recomposition. The only downside is having different calorie and carbohydrate goals throughout the week can make consistency difficult. For those interested in this eating style, our 7 Day Bodybuilding Carb Cycling Meal Plan can help you stay on track.
Intermittent fasting alternates between eating and fasting periods. It's all about when you eat rather than what foods you eat or avoid. During fasting, you abstain from consuming calories, giving your body a break from constant digestion. This method allows your body to tap into stored fat for energy, promoting fat loss.
The most popular intermittent fasting method for body recomposition is the 16/8 method. As the name implies, with this fasting schedule, you limit your eating window to only eight hours daily. Overall, it's a flexible and practical approach that not only aids in weight management but may also offer various health benefits.
Comments: A 16/8 intermittent fasting (IF) diet is excellent if it fits your lifestyle. Many people have success setting up their fasting window in the morning. For example, they start their day with coffee and skip breakfast. In this scenario, the eating window would start with lunch around noon and continue until 8 pm, getting in 2-3 meals.
The challenge is protein intake. With only two or three meals, each one will have to have a lot of protein. Leaning on a protein powder can make it easier. IF is also better for losing body fat than it is for muscle building. Check out our 7 Day 16/8 Intermittent Fasting 7 Day Meal Plan for some help getting started.
The Paleo Diet, short for the Paleolithic diet, takes inspiration from the eating habits of our ancient ancestors during the Paleolithic era. The core idea is to consume foods our hunter-gatherer predecessors would have access to. The Paleo Diet is rich in lean meat, fish, vegetables, nuts, and seeds while avoiding grains, legumes, dairy, and processed foods.
The rationale is rooted in the belief that our bodies are better adapted to the nutritional profile of foods available before the advent of agriculture. By following the paleo diet, proponents aim to support overall health, promote weight loss, and reduce inflammation by embracing a more natural and ancestral approach to eating.
Comments: Overall, the Paleo diet does a lot of things right when it comes to decreasing body fat and increasing lean muscle. It's high in protein, and with the restriction of many carbohydrates and processed foods, it's easy to set it up for fat loss. The biggest weakness of the Paleo diet is the ease of consistency.
The Paleo diet is highly restrictive, making it hard to adhere to over the long haul. Make sure to pick up one of these 7 Best Paleo Protein Powders if you're planning on following this diet.
I hear your first reaction: "Isn't flexible dieting anti-meal plan?"
Not exactly. Flexible dieting has certain degrees of control when you're losing weight. It's not a free-for-all. The best flexible dieters have parameters in place to help them be consistent. Most follow a meal plan.
The only difference is they sprinkle in some treats here and there to support sustainability. If 90% of your diet is healthy, unprocessed foods, the other 10% can come from foods you enjoy. You will notice some treats sprinkled throughout the meal plan. These should be items you love. Feel free to substitute different treats with similar calorie and macronutrient profiles.

If losing fat and gaining muscle at the same time is possible, how do we do it? Here are six tips to move you in the right direction.
Eating a high-protein diet is crucial for simultaneously losing fat and building muscle because protein is essential for muscle repair, growth, and maintenance. When following a calorie-restricted diet for fat loss, a higher protein intake helps preserve lean muscle mass, ensuring that weight loss comes primarily from fat stores rather than muscle.
Additionally, sufficient protein provides the amino acids to synthesize new muscle tissue during muscle-building efforts. In essence, a high-protein diet is a foundation that supports both weight loss and muscle gain. Aiming for around a gram of protein per pound of body weight is sufficient.
However, there is some evidence that even higher protein intakes, upwards of 1.36g per pound, are more favorable to body composition changes3.
Body recomposition is about more than just weight loss. Striving for fat loss, not just to lose weight, is crucial to cut body fat and build muscle simultaneously. Focusing on fat loss ensures the weight you shed comes primarily from excess fat stores rather than valuable muscle tissue.
By preserving lean muscle mass, you create an environment conducive to effective muscle building during strength training. Weight loss alone may involve losing water weight or muscle, hindering the goal of achieving a lean and muscular physique. Prioritizing fat loss enhances the likelihood of successful body recomposition.

I cannot stress enough the importance of sleep quality and quantity for simultaneous fat loss and muscle building. During deep REM sleep, the body releases growth hormones essential for muscle repair and growth.
Additionally, adequate sleep supports hormonal balance, including regulating cortisol levels, which can influence fat storage and muscle breakdown. Research shows that insufficient sleep may increase hunger and cravings, making it harder to adhere to a calorie-controlled diet essential for fat loss4.
Particularly important to recomposition, people trying to lose weight who are sleep deprived lose less fat despite losing a similar amount of weight5. Ultimately, prioritizing good sleep enhances the body's ability to recover, optimize hormone function, and contribute to the success of both fat loss and muscle-building goals.
In a surprise to no one, regularly lifting weights is a critical component of body recomposition. Resistance training benefits in this context are twofold. One, lifting weights stimulates muscle growth, and two, it helps you maintain muscle mass while dieting.
Additionally, muscle tissue requires more energy to maintain than fat, contributing to calorie expenditure even at rest. The bottom line is this: regular weight training creates the ideal conditions for body recomposition, allowing you to achieve a better physique by losing fat and gaining muscle mass.

To build mass and drop fat at the same time, it's not enough to just lift weights. You need to stimulate muscle growth through resistance training and utilize progressive overload.
Progressive overload is the incremental increase in stress placed on the body during exercise, encouraging adaptations such as muscle growth and strength gains over time.
Pay attention to training performance in the gym and write down your sets, reps, and weights in a logbook. Before each workout, peek at your past performances and try to beat your prior numbers.
Be patient. Body recomposition is a long game. Refraining from rushing the process is critical because these transformations take time and consistency. Sustainable changes in body composition require a gradual approach to avoid extreme diets, allowing the body to adapt and minimize the risk of muscle loss.
Patience ensures better habits, reducing the likelihood of setbacks and promoting long-term success in achieving a balanced and sustainable physique. Unlike traditional cutting or bulking, aiming for body recomposition will have subtle changes, often unmeasurable on the scale.
A well-rounded approach that combines proper nutrition, exercise, and select supplements can be beneficial when aiming to lose body fat and build muscle simultaneously. While individual needs vary, here are some evidence-based supplements for those pursuing both muscle gain and fat loss. I've started with my product recommendations, and then dig into why you need them.
Protein intake is crucial for muscle building and repair. Any high-quality protein supplements will do. Whey protein, casein protein, or plant-based options can all help you meet your protein requirements conveniently.

Omega-3s contribute to overall health and can help manage inflammation. Fish oil or algae-based supplements provide essential fatty acids that may aid in fat loss and muscle recovery.
Head to our round-up of the 11 Best Omega-3 Supplements.
Vitamin D is a popular fat-soluble vitamin essential for bone health and may affect muscle function. Adequate vitamin D levels can support overall well-being and potentially aid in fat loss. Consider supplementing with vitamin D, mainly if you don't get a lot of sunlight.
There's no shortage of great options, including any of these 13 Best Vitamin D Supplements.
Have more questions about how to drop body fat and build muscle at the same time? Here are a few answers before you go.
Diets that prioritize a balanced mix of macronutrients, sufficient protein intake, and a small to moderate calorie deficit are effective for fat loss and muscle gain. In my opinion, a flexible dieting approach offers the best strategy for body recomposition.
Body composition refers to the proportion of fat and non-fat mass (muscle, bones, organs, etc.) in the body. Improving body composition means improving your physique by losing fat, building muscle, or both.
Any diet high in protein and rich in whole foods can work to reduce body fat. Emphasize high protein low fat foods, fruits, vegetables, healthy fats, and whole grains while managing calorie intake.
While there's no instant solution, a balanced approach combining a sustainable calorie deficit, regular strength training, and sufficient protein intake offers an effective way to burn fat and gain muscle mass over time.
Eating frequency is flexible, but spreading protein intake across 3-5 meals and snacks throughout the day can support muscle protein synthesis and aid body recomposition.
The best diet for losing fat and increasing muscle mass is a fluid concept. Everyone is entitled to an opinion. While various diets offer effective strategies, choosing a nutrition strategy that aligns with your lifestyle and preferences is critical.
A body recomposition diet needs to be high in protein, but more importantly, it must be something you can stick to. Sustainable progress takes time. You can reach the body you have always wanted by following a flexible diet, staying consistent with workouts, sleeping a little more, and embracing a patient mindset.
All that is left is to do it. Good luck!
