What are unhealthy fats?
Many people think all fats are bad, but that’s simply not true. Unhealthy fats are fats that can contribute to inflammation, poor heart health, weight gain, insulin resistance, and other long-term health problems when eaten regularly in excess. The main unhealthy fats are artificial trans fats and diets that are consistently high in heavily processed fats found in many packaged and fried foods. Some foods high in saturated fat may also be worth limiting, especially when they come from ultra-processed sources rather than whole foods.
The good news is that your body actually needs healthy fats. Rather than fearing fat altogether, it’s far more beneficial to focus on choosing natural, nourishing sources of fat while reducing heavily processed foods that can place extra stress on your body.
🌿 Managing Type 2 diabetes naturally — without relying solely on medication — is possible, and more people are achieving it than ever before. Here’s the realistic roadmap.

Why Your Body Still Needs Fat
Fat is an essential nutrient. It plays an important role in many everyday functions, including:
- Providing long-lasting energy
- Supporting brain function
- Helping absorb vitamins A, D, E and K
- Producing hormones
- Protecting organs
- Keeping skin and joints healthy
The goal isn’t to avoid fat — it is to choose the right kinds.
The Main Types of Unhealthy Fats
Artificial Trans Fats
Artificial trans fats are widely regarded as the least healthy type of dietary fat.
They are created when manufacturers add hydrogen to vegetable oils to make them more stable and extend shelf life. Although many countries have significantly reduced or banned them, they may still appear in some imported or older processed products.
Common sources include:
- Packaged pastries
- Doughnuts
- Some biscuits
- Microwave popcorn
- Deep-fried fast food
- Certain margarines and shortening
Regular consumption has been linked with:
- Increased inflammation
- Higher LDL (“bad”) cholesterol
- Lower HDL (“good”) cholesterol
- Greater risk of heart disease
- Higher risk of type 2 diabetes
Fortunately, checking food labels for “partially hydrogenated oils” can help you avoid them.
Highly Processed Fats
Not every unhealthy fat comes from its chemical structure alone.
Many processed convenience foods combine poor-quality oils with refined sugars, artificial ingredients and excessive salt. This combination may place greater strain on the body’s natural healing processes than whole foods do.
Examples include:
- Crisps
- Fast food
- Frozen ready meals
- Deep-fried takeaway foods
- Commercial baked goods
Rather than focusing on one ingredient, it’s often more helpful to look at the food as a whole. The more processed it is, the less nourishing it generally becomes.
Saturated Fat
Saturated fat has been debated for years.
Current understanding suggests that saturated fat doesn’t need to be completely avoided, but moderation is important. Whole-food sources may fit into a balanced diet for many people, while diets dominated by processed meats and fast food are less beneficial.
Foods containing saturated fat include:
- Fatty cuts of meat
- Butter
- Cream
- Cheese
- Sausages
- Cakes and pastries
For overall wellbeing, many nutrition professionals recommend placing greater emphasis on healthier unsaturated fats instead of relying heavily on saturated fats.
What Makes Unhealthy Fats Harmful?
Our bodies are remarkably good at repairing and maintaining themselves when given the right support.
However, regularly eating highly processed foods rich in unhealthy fats may contribute to:
Increased Inflammation
Chronic, low-grade inflammation has been associated with many long-term health conditions. While no single food causes inflammation on its own, a diet dominated by processed foods can make it more difficult for the body to maintain balance.
Poor Heart Health
Unhealthy fats may negatively affect cholesterol balance and blood vessel health over time, increasing the risk of cardiovascular disease.
Weight Gain
Foods rich in unhealthy fats are often highly processed and calorie dense while being relatively low in nutrients. They may also be less satisfying, making it easier to overeat.
Blood Sugar Imbalance
Many processed foods contain unhealthy fats alongside refined carbohydrates and sugars. This combination can make it more difficult to maintain stable blood sugar levels and may contribute to insulin resistance over time.
Healthier Fat Alternatives
Fortunately, replacing unhealthy fats doesn’t mean sacrificing flavour.
Excellent natural sources of healthier fats include:
- Extra virgin olive oil
- Avocados
- Nuts
- Seeds
- Oily fish such as salmon, sardines and mackerel
- Olives
These foods provide beneficial monounsaturated and polyunsaturated fats, including omega-3 fatty acids, which support overall health.
Simple Ways to Reduce Unhealthy Fats
Making small changes often leads to lasting results. You could try:
Cook More at Home
Preparing meals yourself gives you greater control over the oils and ingredients you use.
Read Food Labels
Avoid products containing partially hydrogenated oils whenever possible.
Choose Whole Foods
Fresh vegetables, fruits, legumes, whole grains, nuts and seeds naturally contain far fewer unhealthy fats than packaged convenience foods.
Bake Instead of Fry
Grilling, steaming, roasting and baking often require much less added fat than deep frying.
Snack Smarter
Swap crisps or pastries for:
- A handful of nuts
- Apple slices with nut butter
- Carrot sticks with hummus
- Plain yoghurt with berries
Small swaps can make a meaningful difference over time.
Looking Beyond Individual Nutrients
It’s easy to become overwhelmed by discussions about fats, carbohydrates or calories. Instead of focusing on individual nutrients, consider your overall eating pattern.
A diet centred on fresh, minimally processed foods naturally provides a better balance of nutrients that support your body’s ability to function well. Regular movement, good sleep, hydration and managing stress also play an important role in long-term wellbeing.
Rather than chasing perfection, aim for consistency. Every healthier choice adds up.
🚫 Some foods are silently destroying your blood sugar — even ones labelled “healthy.” Knowing what to avoid is just as important as knowing what to eat.

Final Thoughts
Unhealthy fats are not simply “all fats.” They mainly refer to artificial trans fats and the poor-quality fats commonly found in heavily processed foods. These foods can contribute to inflammation, poor heart health and metabolic problems when consumed regularly.
Instead of fearing fat altogether, focus on eating more natural, minimally processed foods that provide nourishing fats your body can actually use. Small, sustainable dietary changes often have the greatest impact on long-term health and vitality.
