Are you tired of chasing quick fixes and extreme diets that promise rapid fat loss but leave you feeling frustrated and defeated? You're not alone. One of the most common misconceptions about fat loss is that it requires severe calorie restriction or cutting out entire food groups. (In fact, extreme dieting and severe calorie cutting can backfire on you by slowing down your metabolism.) But what if there was a better way—one that not only delivers sustainable results but empowers you to feel stronger and healthier?

‍

Sustainable fat loss isn't about depriving yourself or engaging in yo-yo dieting; it's about making smart, lasting changes that support your body. Imagine freeing yourself from the cycle of crash diets and instead embracing habits that promote long-term success, boost your metabolism, and enhance your overall well-being. Sustainable fat loss is not only achievable but can also transform the way you approach your health.

‍

Before diving into the natural methods of fat loss, it's important to understand a foundational principle: to lose fat, you must be in a caloric deficit. This means consuming fewer calories than your body uses in a day. Your body burns calories through two main components—Basal Metabolic Rate (BMR) and Active Metabolic Rate (AMR). BMR represents the calories your body needs to maintain basic functions like breathing and digestion, even when at rest. AMR includes the additional calories burned through physical activity. Increasing your muscle mass is one of the most effective ways to boost your BMR, as muscle tissue burns more calories at rest than fat tissue. By building more muscle, you can naturally increase your metabolism, making it easier to maintain a caloric deficit and achieve sustainable fat loss.

‍

Now, let’s explore natural, science-backed methods that will help you burn fat more efficiently, without resorting to extreme diets or unsustainable quick fixes. These strategies will not only promote long-term fat loss but also support your overall health and well-being.

‍

1. Increase Protein Intake for Fat Loss (and Muscle Building)

‍

Yes- it’s true! Increasing protein intake is the first thing you should consider when trying to lose body fat and create more lean muscle mass.  

‍

But why is protein essential when it comes to fat loss?

‍

Firstly, protein increases satiety, aka helps you feel fuller for longer, which can reduce overall calorie intake. By consuming fewer calories, your insulin levels may lower, promoting fat loss as the body taps into stored fat for energy rather than relying on frequent insulin spikes from food intake (1,2). This paired with high-intensity exercise which also lowers fasting insulin and post-meal insulin levels, and increases insulin sensitivity of exercised muscle, explains increases in muscle mass among trained individuals who consume enough protein. (1)

Protein not only keeps you full and reduce cravings (increases satiety), but it also supports muscle growth, which is crucial for burning fat (more on this below). Muscles are metabolically active tissues, meaning they burn calories even at rest (much more compared to fat tissue). Maintaining muscle mass is key to keeping metabolic rates high (6) during weight and particularly fat loss. By increasing muscle mass, you naturally enhance your body's ability to burn fat.  

‍

Furthermore, this higher resting energy expenditure increases overall calorie burn, contributing to thermogenesis. As a result, having more muscle mass boosts your metabolism, leading to greater calorie consumption even when you're not exercising, which can support fat loss over time.  

‍

And protein specifically helps decrease belly fat (the harmful fat that builds up around organs and is a risk factor for many diseases). A higher protein intake (1.3g/kg/day or 0.6g/lb/day was used in this study) can specifically decrease abdominal fat even in men who were limited functionally (unable to exercise). (7)  

‍

How much protein should you have per day to lose fat?

‍

For fat loss, it’s recommended to consume between 0.7 to 1 gram of protein per pound of body weight per day (or 1.2 to 2.20 grams per kilogram of body weight per day) (8), depending on your activity level and muscle-building goals. Focus on high-quality sources like lean meats (lean chicken breast, steak), fish, eggs, and plant-based proteins such as lentils, beans, and tofu (high quality “complete” proteins that have all essential amino acids).

‍

For example, a 180 lb person aiming to consume between 0.7 and 1 gram of protein per pound of body weight per day, the daily protein intake would range from 126 grams (minimum) to 180 grams (maximum). Here's an example of how that daily intake could look, aiming for an average, 150g of protein, spread across three meals and snacks:

‍

Breakfast:

• 3 eggs (18 grams of protein)

• 1 cup of Greek yogurt (20 grams of protein)

• 1 slice of whole grain toast with 1 tbsp peanut butter (8 grams of protein)

Total for breakfast: 46 grams of protein

‍

Lunch:

• 5 oz grilled chicken breast (43 grams of protein)

• 1 cup quinoa (8 grams of protein)

• 1 cup of steamed broccoli (3 grams of protein)

Total for lunch: 54 grams of protein

‍

Snack:

• 1 whey protein shake (25 grams of protein)

Total for snack: 25 grams of protein

‍

Dinner:

• 6 oz salmon fillet (40 grams of protein)

• 1 cup cooked lentils (18 grams of protein)

• 1 cup mixed vegetables (5 grams of protein)

Total for dinner: 63 grams of protein

‍

Total for the day: 150 grams of protein

‍

If you are wondering how you are going to eat that much protein every single day, while remaining in a calorie deficit, you are not alone. This is a difficult feat for most people.  

‍

So, if fat loss is your goal and it’s hard to meet your daily protein intake through food alone, consider supplementing it with a whey protein or plant-based protein powder. Whey isolate protein is easily absorbed and provides a complete amino acid profile, supporting muscle repair and fat loss!

‍

It’s common for women to worry that strength training and increasing protein intake will lead to a "bulky" or overly muscular appearance. However, building lean muscle is a key part of fat loss and will actually help you achieve a toned, sculpted physique rather than a bulky one. Instead, strength training combined with proper protein intake will help you increase metabolism, burn fat more efficiently, and develop a lean, strong body that supports your health and fitness goals.

‍

Bottom line: Protein not only boosts satiety and curbs cravings, but it also supports muscle growth and increases metabolism and thermogenesis, making it a powerful tool for burning fat and enhancing overall fat loss. (Especially when combined with high-intensity exercise.)

‍

2. Induce thermogenesis (the body generates heat and burns calories)

‍

Thermogenic compounds increase your body's heat production, helping to boost metabolism and burn more fat. Some natural bioactive compounds that have well studied thermogenic effects include:

‍

• Green Tea Extract actually, contains two components that have thermogenic effects. It is rich in catechins specifically epigallocatechin gallate aka EGCG, and caffeine. (16, 17) While caffeine as mentioned above increases adrenaline the EGCG component slows down its breakdown making it extra effective. (18) Studies have shown that this combo (caffeinated green tea) can increase metabolism by 4% and boost fat burning by 16% for up to 24 hours. (19)

• Caffeine, a stimulant naturally found in coffee and tea stimulates the sympathetic nervous system, and increases the levels of adrenaline, a hormone that stimulates fat cells to release fatty acids where they can be used for energy (aka fat oxidation and fatty acid turnover) both during rest and during exercise. (11,12) Caffeine has also been found to boost metabolism especially resting energy (increase energy expenditure) while at the same time reducing energy intake. (15) Doses of approximately 1.4-2.3mg of caffeine per pound are most effective. (14)

• Capsaicin (active compound in cayenne peppers which gives them their heat- the spicier the more capsaicin!) speeds up metabolism through the same mechanism of caffeine, the release of adrenaline, which ultimately burns more calories. (20) Studies have found capsaicin supplements can burn 50 more calories per day (21) and burn 10% more fat in 24 hours (at 2.5mg). (22)

‍

These thermogenic compounds naturally boost calorie burn, making it easier to shed fat.

‍

So you can add an extra cup of green tea to your daily routine or get the benefit of a concentrated amount of ECGC supplement form.

‍

Supplements to consider: Look for supplements that contain green tea extract, caffeine, or capsaicin or a blend as studies have found that the synergistic (when they all work together in harmony, they work better than one on its own) effect of these agents provide an extra boost in metabolism especially when combined with exercise. (23, 24)

‍

Bottom Line: Thermogenic compounds including green tea extract, caffeine, and capsaicin naturally boost metabolism and increase fat burning especially when combined with exercise. A combo is better than one.

‍

3. Support Fat Metabolism with Carnitine

‍

L-Carnitine is a naturally occurring amino acid derivative that plays a key role in fat metabolism, and energy production. It helps transport fatty acids into the mitochondria (27), where they can be oxidized and used for energy. This process helps the body utilize fat stores more efficiently, promoting fat loss while supporting energy production. A meta-analysis of 37 randomized controlled trials found that l-carnitine supplementation at 2000mg provides a modest reduction in body weight, BMI and fat mass especially in overweight or obese adults. (26)

When your body can efficiently use fat for fuel, you can maintain higher energy levels during workouts (l-carnitine has some great exercise performance benefits too) making it easier to perform at your best and burn more calories contributing to weight loss and fat loss.  

‍

Food sources of L-carnitine: Animal-Based Sources (Highest in L-carnitine):

‍

1. Beef: One of the richest sources; approximately 81 mg of L-carnitine per 3 oz (85 g) serving.

2. Pork: Contains around 24 mg per 3 oz (85 g) serving.

3. Fish (especially cod): Around 5 mg per 3 oz (85 g) serving.

4. Lamb: Richer than chicken and fish, lamb provides around 80 mg per 3 oz serving.

5. Chicken: About 3 to 5 mg per 3 oz (85 g) serving.

6. Milk: Provides around 8 mg per 1 cup (240 ml).

7. Cheese (especially cheddar and cottage cheese): Contains small amounts of L-carnitine, around 2 mg per serving.

‍

Plant-Based Sources (Lower in L-carnitine):

• While most plant foods contain very low levels of L-carnitine, some trace amounts can be found in:

• Avocados

• Whole wheat bread

• Asparagus

• Tempeh (fermented soy)

‍

However, plant-based sources generally provide much lower levels of L-carnitine compared to animal products. For individuals following a vegetarian or vegan diet, supplementation is often recommended if higher L-carnitine intake is needed for health or fitness goals.

Supplements to consider: Acetyl-L-Carnitine (ALCAR) is a highly bioavailable form of carnitine that can also support brain health and cognitive function, making it a good choice for fat oxidation and overall wellness.

‍

Bottom Line: L-Carnitine helps your body burn fat more efficiently for energy, supporting fat loss and boosting workout performance, with 2000mg shown to modestly reduce weight and fat in overweight adults. Acetyl-L-Carnitine also benefits brain health, making it a great all-around supplement.

‍

4. Maintain Muscle Mass to Burn More Fat

‍

As touched on briefly above, building and maintaining muscle is one of the most effective ways to lose fat naturally. Muscle is metabolically active, meaning it burns more calories than fat even when you're at rest. The more muscle you have, the higher your resting metabolic rate, which means you burn more fat throughout the day.

‍

How to build muscle? To build muscle, you need to focus on strength training and adequate protein intake (see above). However, along with protein, there are a few very well researched supplements that can significantly improve your ability to increase lean muscle mass:

‍

• Branched-Chain Amino Acids (BCAAs): Leucine, isoleucine, and valine are essential for muscle protein synthesis and recovery. L-leucine is particularly important for MPS (muscle protein synthesis). (32, 33)

• Creatine Monohydrate: One of the most researched supplements for building strength and muscle mass, creatine enhances energy production in muscles during high-intensity exercise. (30, 31)

‍

Supplements to consider: BCAA supplements can help reduce muscle breakdown during workouts, while creatine can support muscle growth and performance, allowing you to train harder, recover faster and build more muscle. The more you can maintain lean muscle mass, the more you will lose fat.  

‍

Bottom Line: Building and maintaining muscle boosts your resting metabolic rate, helping you burn more fat throughout the day. Strength training, along with protein, BCAAs, and creatine, can significantly enhance muscle growth and performance, making fat loss easier and more effective.

‍

5. Optimize with healthy fats (like Omega-3 Fatty Acids)

‍

Wait a minute, increase fat to lose fat? Yes- you read that correctly!  

‍

Most people are unaware of how important healthy fats such as omega-3 fatty acids are on your fat loss journey.  

‍

Omega-3 fatty acids, found in fish oil and flaxseeds, are well-known for their anti-inflammatory properties, but they can also help with fat loss. Omega-3s may improve metabolic health, increase fat burning, and enhance insulin sensitivity, which helps your body use carbohydrates more efficiently rather than storing them as fat.

‍

Omega-3s have been found in research to support weight loss and fat loss, especially around the abdomen. (38, 34) Several studies have shown that using omega-3 fatty acids for more than 6 weeks can boost metabolic rate and reduce overall body fat, making them an effective supplement for fat loss and improving metabolic health. (35, 36, 37)

‍

There are other healthy fats that may have a similar impact to fish oil including MCT oil, adding 1.5-2 Tbsp to your diet per day can boost fat burning and olive oil has been shown to have a positive impact on fat and body mass. (39, 40).  

‍

Foods High in Omega-3 Fatty Acids:

1. Fatty Fish (best sources of omega-3s EPA and DHA):
   1. Salmon
   2. Mackerel
   3. Sardines
   4. Herring
   5. Anchovies
   6. Tuna

2. Chia Seeds: Excellent plant-based source of omega-3s (ALA). Also high in fiber, helping with satiety.

3. Flaxseeds: Rich in omega-3 ALA. Ground flaxseeds are easier for the body to absorb.

4. Walnuts: High in ALA omega-3 fatty acids and also provide healthy fats that promote heart health.

5. Hemp Seeds: Contain omega-3 ALA and are a great source of protein and healthy fats.

6. Algal Oil: A plant-based omega-3 supplement derived from algae, which is high in EPA and DHA, similar to fish oil.

7. Edamame: Young soybeans that contain a moderate amount of omega-3 ALA and are a good plant-based protein source.

‍

Foods High in Other Healthy Fats (Monounsaturated and Polyunsaturated Fats):

1. Avocados: Rich in monounsaturated fats, which are heart-healthy and help improve fat metabolism and satiety.

2. Olive Oil: High in monounsaturated fats, which support fat loss by improving cholesterol levels and aiding in reducing body fat.

3. Nuts and Seeds (besides walnuts):

1. Almonds: High in monounsaturated fats and also support satiety.

2. Pistachios: A good source of healthy fats and plant-based protein.

3. Sunflower seeds: Provide a good balance of polyunsaturated and monounsaturated fats.

4. Coconut Oil: Contains medium-chain triglycerides (MCTs), which are more easily burned for energy and may promote fat loss.

5. Ghee or Clarified Butter: Contains healthy fats, particularly short- and medium-chain fatty acids, that may support metabolism.

6. Eggs: Particularly the yolks, which are rich in healthy fats, including omega-3s (if they are pasture-raised or omega-3-enriched).

‍

Supplements to consider: The reality is getting fatty fish in the diet in the amount needed for fat loss is nearly impossible. A high-quality fish oil supplement with concentrated EPA and DHA can provide you with the omega-3s needed to support fat loss and overall health.

Bottom Line: Healthy fats, especially omega-3 fatty acids, not only support fat loss by improving metabolic health and enhancing fat burning, but they also help regulate insulin sensitivity, making fat loss more efficient, particularly around the abdomen. Including these fats in your diet or supplementing them with high-quality fish oil can effectively boost fat metabolism and overall health.

‍

So, there you have it: 5 ways to lose fat naturally! And it doesn’t require extreme dietary measures or deprivation.  

These strategies not only help you burn fat but also improve your overall health and energy levels, ensuring that you look and feel your best in the long term.
