Eating fat makes you fat, right? Let me share about my own weight loss journey. I grew up in a blue zone community and we ate a healthy whole food diet that included plenty of fats from whole foods. I never struggled with my weight. When I was a young mom, working full time and juggling the responsibilities of kids and career, I turned to processed and pre-prepared foods as a way to make my life easier. It With the new diet I slowly began to gain weight and for the next 40 years I struggled with my weight. Like many, I believed the age-old adage that “eating fat makes you fat.” For years, I tried many low-fat diets, filling my plate with “diet” foods and processed low-fat alternatives. Despite my best efforts, the scale continued to climb, and I found myself constantly battling cravings and fatigue.
Frustrated and on the verge of giving up, I realized the diet of my Blue Zone childhood may just be the answer to my weight struggles. I made a bold decision: to eliminate processed foods from my diet and instead focus on whole foods, I prioritized protein, reduced carbohydrates, and included foods rich in healthy fats.
The transformation was remarkable. Within weeks, my energy levels increased. The constant hunger pangs that had plagued me on low-fat diets disappeared. Most surprisingly, the pounds began to melt away. By incorporating avocados, nuts, olive oil, and fatty fish into my meals, I not only achieved my weight loss goals but also experienced improvements in my skin, hair, and overall well-being.
My journey is not unique. It reflects a paradigm shift in our understanding of fats and their role in weight management and health. For decades, we’ve been told that eating fat makes you fat. This long-standing belief has been a cornerstone of dietary advice, shaping food choices and diet trends for generations. But what if we told you that this widely accepted “truth” isn’t as straightforward as we once thought?
Recent research has turned this notion on its head, revealing a more complex and nuanced relationship between dietary fats and weight management. Let’s dive into the fascinating world of healthy fats and their surprising role in supporting weight loss and overall health.

Let’s dive into the fascinating world of healthy fats and their surprising role in supporting weight loss and overall health.
The Satiety Factor: Feeling Fuller for Longer
One of the most significant advantages of including healthy fats in your diet is their ability to keep you feeling satisfied for extended periods. Unlike carbohydrates, which can lead to rapid spikes and crashes in blood sugar levels, fats provide a steady source of energy that helps curb hunger pangs.
Research supports this satiety effect. A study by Larsson et al. found that leptin levels, a hormone associated with feelings of fullness, were negatively correlated with total energy intake, carbohydrate intake, and fat intake. This suggests that higher leptin levels, which are associated with fat intake, may contribute to increased satiety and potentially lead to reduced overall calorie consumption throughout the day.
Practical Tip: Try incorporating a small handful of nuts as a mid-morning snack. The healthy fats and protein content can help keep you feeling full until lunchtime, reducing the temptation to reach for less nutritious options.
Metabolic Magic: Boosting Your Body’s Fat-Burning Potential
Believe it or not, certain types of healthy fats can actually give your metabolism a boost. Medium-chain triglycerides (MCTs), found in foods like coconut oil, have been shown to increase energy expenditure and fat oxidation.
A comprehensive meta-analysis by Mumme and Stonehouse revealed that MCTs decreased body weight, waist circumference, and total body fat compared to long-chain triglycerides. This research indicates that incorporating MCTs into your diet could potentially enhance your body’s ability to burn fat and support weight loss efforts.
Practical Tip: Try swapping your regular cooking oil for coconut oil in some meals to introduce more MCTs into your diet. Remember, moderation is key – coconut oil is still calorie-dense, so use it judiciously.
Hormone Harmony: The Fat-Hormone Connection
Adequate fat intake plays a crucial role in hormone production and regulation. Hormones like leptin and insulin are key players in appetite control and fat storage, and they rely on dietary fats to function optimally.
A review by Fried et al. demonstrated that insulin and glucocorticoids work synergistically to upregulate leptin mRNA levels and rates of leptin secretion in human adipose tissue. This research underscores the importance of healthy fats in maintaining hormonal balance, which can have a significant impact on weight management and overall health.
Practical Tip: Include a variety of healthy fat sources in your diet, such as avocados, olive oil, and fatty fish like salmon. These foods provide essential fatty acids that support hormone production and regulation.
The Mediterranean Example: A Fat-Friendly Approach to Health
When we look at populations with traditionally healthy diets, the Mediterranean diet stands out as a shining example. This eating pattern, rich in healthy fats from sources like olive oil, nuts, and fish, is associated with lower rates of obesity and better overall health outcomes.
A comprehensive review by Dominguez et al. analyzed multiple meta-analyses and found compelling evidence supporting the Mediterranean diet’s effectiveness for weight management. Four meta-analyses of randomized controlled trials showed a greater reduction in body weight and BMI with the Mediterranean diet compared to other diets. Furthermore, a meta-analysis of 7 prospective cohort studies found a reduced risk of becoming obese and gaining weight over time associated with higher adherence to the Mediterranean diet.
Practical Tip: Embrace Mediterranean-inspired meals by drizzling extra virgin olive oil over salads, snacking on a mix of nuts and seeds, and including fatty fish in your meal plan at least twice a week.
The Low-Fat Diet Dilemma: When Less Isn’t More
The 1980s and 1990s saw the rise of the low-fat diet craze, with fat being vilified as the primary culprit behind weight gain and heart disease. However, this period coincided with a significant increase in obesity rates, challenging the effectiveness of this approach.
The CORDIOPREV study, a randomized controlled trial, compared a Mediterranean diet rich in extra-virgin olive oil to a low-fat diet in coronary heart disease patients. The results were eye-opening: the Mediterranean diet produced a lower decline in estimated glomerular filtration rate (eGFR) compared to the low-fat diet, particularly in patients with type 2 diabetes. This suggests that low-fat diets may not be as effective as previously thought, and that including healthy fats can have beneficial effects on overall health.
Practical Tip: Instead of focusing solely on reducing fat intake, aim for a balanced approach that includes moderate amounts of healthy fats alongside plenty of fruits, vegetables, lean proteins, and whole grains.
Addressing the Counterarguments: A Balanced Perspective on Eating Fats makes you Fat.
While the evidence supporting the benefits of healthy fats is compelling, it’s important to address potential counterarguments and maintain a balanced perspective.
Calorie Density: Mindful Consumption is Key
It’s true that fats are more calorie-dense than carbohydrates or proteins, providing 9 calories per gram compared to 4 calories per gram for the other macronutrients. This higher calorie density means that it’s easier to overconsume fats if you’re not mindful of portion sizes.
The Solution: Practice portion control and be aware of the calorie content of fat-rich foods. Use tools like measuring spoons or a food scale to ensure you’re not inadvertently consuming excess calories.
Not All Fats Are Created Equal
While we’ve focused on the benefits of healthy fats, it’s crucial to acknowledge that not all fats are beneficial. Trans fats found in nearly all of the processed and prepared foods. This unhealthy fat is in about 70% of the foods consumed in a typical American’s diet. This excessive amount of trans fats has negative health impacts, including increased risk of heart disease and obesity.
The Solution: Focus on incorporating unsaturated fats (both monounsaturated and polyunsaturated) from sources like olive oil, avocados, nuts, seeds, and fatty fish. Limit intake of saturated fats from red meat and full-fat dairy, and avoid processed and prepackaged foods that are high in trans fats found. Avoid the use of seed oils
Individual Variations: One Size Doesn’t Fit All
It’s important to recognize that individuals may respond differently to high-fat diets due to genetic factors or existing health conditions. What works for one person may not be ideal for another.
The Solution: Pay attention to how your body responds to changes in your diet. If you have existing health conditions or concerns, consult with a healthcare professional or registered dietitian before making significant changes to your fat intake.
Practical Tips for Incorporating Healthy Fats into Your Diet
Now that we’ve explored the science behind healthy fats and weight management, let’s look at some practical ways to incorporate these beneficial fats into your daily meals:
- Start your day right: Add a quarter of an avocado to your morning toast or blend some nut butter into your smoothie for a satisfying breakfast.
- Upgrade your salads: Drizzle extra virgin olive oil over your salads and add a sprinkle of seeds or chopped nuts for extra crunch and healthy fats.
- Snack smart: Keep a mix of unsalted nuts and seeds on hand for a quick, satisfying snack that’s rich in healthy fats and protein.
- Cook with care: Use coconut oil or olive oil for cooking at low to medium temperatures. For high-heat cooking, opt for avocado oil, which has a higher smoke point.
- Go fish: Aim to include fatty fish like salmon, mackerel, or sardines in your meal plan at least twice a week to boost your intake of omega-3 fatty acids.
- Dress it up: Make your own salad dressings using extra virgin olive oil as a base. Add herbs, spices, and a splash of vinegar or citrus juice for flavor.
- Spread the health: Replace butter or margarine with mashed avocado or nut butter on your toast or sandwiches.
Frequently Asked Questions
Q: Won’t eating more fat make me gain weight?
A: Not necessarily. While fats are calorie-dense, consuming healthy fats as part of a balanced diet can actually support weight loss by increasing satiety, boosting metabolism, and regulating hormones. The key is to focus on healthy fats from sources like avocados, nuts, seeds, and olive oil, while maintaining overall calorie balance.
Q: How much fat should I include in my diet for weight loss?
A: The ideal fat intake varies by individual, but generally, healthy adults should aim for 20-35% of their daily calories from fat. For a 2000-calorie diet, this translates to about 44-78 grams of fat per day. Focus on unsaturated fats and consult with a registered dietitian for personalized advice.
Q: Are all saturated fats bad for you?
A: While it’s best to limit saturated fat intake, not all saturated fats are created equal. For example, the saturated fats in coconut oil (MCTs) may have some health benefits. However, it’s still important to consume saturated fats in moderation and focus more on unsaturated fats for overall health.
Q: Can I eat nuts every day if I’m trying to lose weight?
A: Yes, you can include nuts in your daily diet, even when trying to lose weight. Nuts are rich in healthy fats, protein, and fiber, which can help with satiety and weight management. However, because they are calorie-dense, it’s important to control portion sizes. A small handful (about 1 ounce) per day is a good target for most people.
Q: How can I incorporate more healthy fats into my diet if I don’t like fish?
A: While fatty fish are excellent sources of omega-3 fatty acids, there are many other ways to include healthy fats in your diet. Try adding avocado to your sandwiches or salads, using olive oil in cooking and dressings, snacking on nuts and seeds, or incorporating chia seeds or ground flaxseed into your smoothies or oatmeal. Plant-based omega-3 supplements derived from algae are also available if you’re concerned about meeting your omega-3 needs.
Q: Are seed oils really that bad for you?
A: While seed oils aren’t inherently “bad,” their overconsumption in the modern diet has raised concerns among nutrition experts. These oils are high in omega-6 fatty acids, which, when consumed in excess, may contribute to inflammation. They’re also often highly processed. It’s generally recommended to eliminate seed oil intake and substitute olive or avocado oil when using oil for cooking. Focus on whole food fat sources or less
