You've probably heard of all sorts of diets these days that claim to help you lose weight. One of the most talked about is the Paleo Diet. Following this diet can help you lose weight by eating more lean meats, fish, fruits, vegetables, and nuts, and by cutting down on carbohydrates, sugar, and processed foods. But the question is, how does the Paleo diet affect your cholesterol levels? Let's find out more about it.
First, let's understand this 'good' and 'bad' cholesterol.
When you talk about cholesterol, you may have heard of two types: 'good cholesterol' and 'bad cholesterol.' Let's see what the difference is between the two.
- LDL (Low-Density Lipoprotein) or 'bad' cholesterol: Simply put, this is our enemy. When LDL cholesterol levels increase, they start to deposit like grease on the walls of our blood vessels. Think of it like dirt building up inside a water pipe. In medical terms, we call this atherosclerosis . When blood vessels become clogged in this way, the risk of developing serious diseases like heart attack and stroke increases significantly.
- HDL (High-Density Lipoprotein) or 'good' cholesterol: This is our friend. HDL picks up the bad LDL cholesterol that has built up in your blood vessels and takes it to the liver to be broken down. This means that having high levels of HDL in your body means that you are protected from the risk of heart attack and stroke.
In addition to these two, there is also something called triglycerides . These are the most common type of fat in our bodies. If your triglyceride levels are high, and your LDL levels are also high (or your HDL levels are low), your risk of fatty deposits in your blood vessels increases.
What do we eat and not eat on the 'Paleo Diet'?
Let's take a clear look at what people on a Paleo diet typically eat and what they don't. This will give you a good idea of what to expect.
| ✅ Recommended things to eat | ❌ Things to avoid |
|---|---|
| Fresh fruits and vegetables | Cereals (wheat, oats, barley) |
| Nuts and oils derived from nuts (e.g. olive oil, walnut oil) | Legumes (beans, lentils, peanuts, chickpeas) |
| Lean meats (especially grass-fed) | Milk and dairy products (yogurt, cheese) |
| Fish rich in Omega-3 fatty acids (salmon, mackerel, herring, tuna) | Refined sugar |
| Eggs | Salt (excessive use) |
| Potato | |
| Highly processed foods |
Looking at it this way, there are several benefits to the body from cutting out artificial ingredients and eating more natural foods:
- Weight loss.
- Controlling blood sugar levels.
- Blood pressure control.
- Decreased triglyceride levels.
- Ability to better manage appetite.
So, when all of this is combined, cholesterol levels should be reduced, right? The real answer is: "It may or may not be."
Why is there no clear answer?
The main reason for this is that the 'Paleo diet' is not something that everyone follows exactly the same way. There are big differences in how each person follows this diet.
Not everyone's 'Paleo' diet is the same.
Some people follow a paleo diet that is low in fat and slightly high in carbohydrates (e.g., more fruits and vegetables, less meat). Others follow a high-fat, very low-carb diet (e.g., more red meat and oils). So the effects of these two diets on cholesterol may be different.
The Saturated Fat Problem
The Paleo diet does not limit the consumption of red meats like beef and pork. These meats are high in saturated fat . Because saturated fat has been linked to high cholesterol, organizations like the American Heart Association recommend that you consume less than 6% of your daily calories from saturated fat. That's about 11-13 grams per day for the average person. You can reach this level very quickly.
The importance of fiber
Fiber is very important for lowering cholesterol levels. Fiber is found mostly in plant foods. Since the Paleo diet excludes grains and legumes, some people may have a reduced fiber intake.
The best solution is to include as many vegetables as possible in your diet, which are rich in vitamins, minerals, and fiber . These contain complex carbohydrates. These are completely different from simple carbohydrates like sugar. Eating too much sugar can increase cholesterol.
What does the research say?
In fact, the results of research on this are mixed.
- In one small study, people who followed the Paleo diet for 10 weeks had slightly increased levels of bad cholesterol (LDL) and total cholesterol.
- However, other research has shown that the Paleo diet can increase good cholesterol (HDL) levels and lower blood sugar levels. This also helps reduce damage to blood vessels.
Simply put, how this diet affects your cholesterol depends on your genes, how much exercise you do, and the amount of fat and fiber in the foods you eat .
"We can't come to a firm conclusion on this yet. More research is needed on the long-term effects of this diet. So it's wise to seek medical advice before you start a diet like this, especially if you have a cholesterol problem."
What should I do?
If you're concerned about your cholesterol levels, or are considering starting a diet like Paleo, the most important thing to do is talk to your family doctor or a dietitian.
They can guide you on what is best for you based on your health history, current cholesterol levels, and lifestyle. Remember, the most important thing is not to follow a fad diet, but to manage your overall health well. A healthy diet combined with regular exercise will also help you along the way.
Take-Home Message
- Although the Paleo Diet can provide benefits such as weight loss, the effects on cholesterol may vary from person to person.
- The amount of saturated fat and fiber you eat directly affects your cholesterol levels. Cut down on red meat and eat more vegetables.
- Before starting any diet, be sure to talk to your doctor, especially if you have a condition like cholesterol, diabetes, or heart disease.
- Exercise and a balanced lifestyle are more important for health than any diet.
