Why Fats Are Vital on a Cut
During a cutting diet, the primary goal is to create a calorie deficit to burn fat while preserving lean muscle mass. While it may seem logical to slash fat intake to the bare minimum due to its calorie density (9 calories per gram), this approach can be counterproductive and detrimental to your health. A moderate intake of healthy fats is essential for several key physiological functions that support a successful and sustainable cut.
The Role of Healthy Fats
- Hormone Production: Fat plays a critical role in the production of vital hormones, including testosterone, which is crucial for maintaining muscle mass. A diet too low in fat can disrupt hormonal balance.
- Satiety and Appetite Control: Fats slow down digestion, helping you feel full and satisfied for longer. This is a significant advantage when in a calorie deficit, as it can help manage hunger and reduce the temptation to overeat.
- Nutrient Absorption: Healthy fats are necessary for the absorption of fat-soluble vitamins (A, D, E, and K), which are essential for overall health and well-being.
- Reduced Inflammation: Certain fats, particularly omega-3s, have anti-inflammatory properties that can aid recovery from intense workouts and promote general health.
The Best Fats to Prioritize
When planning what fats to eat on a cut, the focus should be on unsaturated fats, specifically monounsaturated and polyunsaturated fats.
Monounsaturated Fats (MUFAs)
These fats are found in plant-based oils, nuts, and high-fat fruits. MUFAs are known for their heart-healthy benefits and anti-inflammatory effects.
- Key Sources of MUFAs:
- Avocados: A versatile source that provides creamy texture and can be added to salads, sandwiches, or smoothies.
- Olive Oil: Use extra virgin olive oil for cooking at moderate temperatures, as a salad dressing, or to flavor dishes.
- Nuts: Almonds, cashews, and hazelnuts are great snacks in moderation.
- Seeds: Sesame and pumpkin seeds are excellent additions to meals.
Polyunsaturated Fats (PUFAs)
This category includes the essential omega-3 and omega-6 fatty acids, which the body cannot produce on its own. Omega-3s are particularly beneficial for heart and brain health and reducing inflammation.
- Key Sources of PUFAs:
- Fatty Fish: Salmon, mackerel, herring, and sardines are rich in omega-3s. Aim for two servings per week.
- Seeds: Flaxseeds and chia seeds are plant-based sources of omega-3s, perfect for adding to yogurt, oatmeal, or salads.
- Walnuts: Another great source of omega-3s, walnuts make for a healthy, satisfying snack.
- Vegetable Oils: Soybean and sunflower oils contain PUFAs.
Fats to Limit and Avoid
While healthy fats are crucial, not all fats are created equal. Limiting or eliminating unhealthy fats is a critical part of a successful cutting diet.
Saturated Fats
Found primarily in animal products and processed foods, saturated fats should be limited, but not necessarily eliminated. Replacing saturated fats with unsaturated fats has shown health benefits.
- Sources to Moderate:
- Fatty cuts of red meat
- High-fat dairy products like butter, cream, and full-fat cheese
- Some plant-based oils like coconut and palm oil
Trans Fats
Artificial trans fats are created through a process called hydrogenation and are linked to significant health risks. The FDA has largely removed them from the US food supply, but they can still be found in small amounts in some animal products and fried foods. These should be avoided entirely.
Comparison of Fat Sources
| Feature | Healthy Unsaturated Fats | Unhealthy Saturated & Trans Fats |
|---|---|---|
| Primary Sources | Plant-based foods, fatty fish | Animal products, processed foods |
| Effect on Cholesterol | Can help lower LDL (bad) cholesterol | Can raise LDL (bad) cholesterol |
| Inflammation | Generally anti-inflammatory | Can promote inflammation |
| Fat-Loss Support | Boosts satiety, aids hormone function | Provides calories with fewer benefits |
| Examples | Avocado, olive oil, salmon, nuts, seeds | Butter, lard, fried foods, processed snacks |
How to Strategically Incorporate Healthy Fats
Practical Strategies
- Salad Dressings: Create your own dressings with extra virgin olive oil and vinegar instead of using store-bought versions that may contain unhealthy additives.
- Cooking Fats: Use olive or canola oil for cooking instead of butter or lard.
- Snack Swaps: Swap sugary or processed snacks for a handful of nuts or seeds.
- Protein Enrichment: Add seeds like flax or chia to your protein shakes, oatmeal, or yogurt for extra healthy fats.
- Meal Planning: Incorporate fatty fish like salmon into your weekly meal plan to get a consistent source of omega-3s.
The Bottom Line
Successful cutting isn't about eliminating fat, but rather about choosing the right types of fat in the correct quantities. By prioritizing nutrient-dense, unsaturated fats from sources like avocados, olive oil, and fatty fish, you can support essential bodily functions, manage your appetite, and optimize your fat-loss efforts. Always remember that even healthy fats are calorie-dense, so moderation and mindful portion control are key to staying within your calorie deficit.

Conclusion
Understanding what fats to eat on a cut is a fundamental component of a successful diet strategy. By focusing on quality over quantity and prioritizing unsaturated fats, you can sustain your energy, keep hormones balanced, and stay satisfied while in a calorie deficit. Strategic incorporation of healthy fats from whole food sources will not only help you achieve your physique goals but also improve your overall health.
