The Atkins diet is a popular low-carb diet claimed to be beneficial for weight loss.  It involves eating as much protein and fat as you want and limiting carb intake.

Low-carb diets have been shown in numerous studies to promote weight loss and overall health.

Initially, the diet was considered unhealthy because of its high saturated fat content. Today, the effect of saturated fat on health and heart disease is being discussed.

Here are the basics you need to know about Atkins diet.

Saturated Fat’s Effect on Health and Heart Disease

Eating saturated fat has been shown in several studies to increase LDL (bad) cholesterol, which can contribute to cardiovascular disease.

Some reviews concluded that replacing saturated fat with polyunsaturated fat may cause a 30% reduction in cardiovascular disease risk.

However, other reviews found no association between lowering saturated fat intake and reduction in cardiovascular disease risk.

Nevertheless, low-carb diets like the Atkins diet have been suggested in some studies to cause more weight loss and greater improvements in triglycerides, HDL (good) cholesterol, and blood sugar than low-fat diets.

This is because reduced carb intake and increased protein consumption may result in reduced appetite, thus helping you eat fewer calories.

Four Phases of the Atkins diet

It is always best to seek the advice of a registered dietitian or physician before getting started with a new weight loss diet plan.

But here are four phases of the Atkins diet for your proper guidance.

Phase 1. The first phase is induction, which kick-starts the weight loss.  This phase involves limiting carb consumption to < 20 grams per day and eating high-fat, high-protein foods for 2 weeks.

Phase 2. The second phase is balancing, wherein you can add small amounts of fruit and more low-carb vegetables back to your diet.

Phase 3. The third phase is fine-tuning. This is when you add more carbs to your diet when you’re about to achieve your target goal weight to slow down weight loss.

Phase 4. This phase is all about maintenance, in which you can eat as many healthy carbs as your body can tolerate without gaining weight again.

However, you can still follow the Atkins diet without necessarily going through all these phases.

For example, you can skip the induction phase and start by eating more low-carb vegetables and fruits. This can be a great way to ensure you are getting enough fiber and other essential nutrients.

Foods to Eat

The Atkins diet encourages the following foods:

• Eggs (choose pastured or omega-3 enriched)
• Meats (such as pork, beef, bacon, and chicken)
• Fatty fish and seafood (such as trout, salmon, mackerel, and sardines)
• Low-carb vegetables (such as broccoli, spinach, kale, and asparagus)
• Nuts and seeds (such as walnuts, macadamia nuts, almonds, and chia seeds)
• Healthy fats (such as avocados, avocado oil, coconut oil, and extra virgin olive oil)
• Full-fat dairy (such as cream, cheese, butter, and full fat yogurt)

There are also plant-based alternatives for vegetarians to make sure they are meeting their nutrient needs while on the Atkins diet. These include soy-based foods like tofu and edamame, nuts and seeds, and olive oil and coconut oil. Lacto-ovo-vegetarians can also eat eggs and other high fat dairy foods.

The diet also allows the following beverages: water, coffee, and green tea. Drinking alcohol in small amounts is also allowed but make sure to avoid high-carb drinks like beer.

Foods to Limit

The following carb-rich foods should be avoided or limited when following the Atkins diet.

• Grains (such as rice, rye, wheat, and spelt)
• Artificial sugar
• “Diet” and “low fat” foods

The following should be limited during the induction phase only.

• High carb vegetables (such as turnips and carrots)
• High carb fruits (such as apples, oranges, pears, bananas, and grapes)
• Starches (such as potatoes and sweet potatoes)
• Legumes (such as beans and lentils)

Potential Downsides

Although there are several advantages of Atkins diet, such as weight loss and other favorable metabolic changes, there are also potential downsides.

During the induction phase, you may experience weakness, headache, dizziness, fatigue, low blood sugar, electrolyte imbalance, and kidney problems.

Limiting carb-rich foods may also put you at risk of insufficient fiber intake, since a large portion of the fiber we consume comes from whole grains, which is restricted on the Atkins diet. Take note that fiber supports gut motility and healthy gut microbiota, helps control appetite, and protects against heart disease and certain cancers.

Also, the diet’s high saturated fat content may increase LDL (bad) cholesterol in some people, which may increase heart disease risk, though study results are mixed.

The Take-Home Message

The Atkins diet may be an effective weight loss tool for some individuals. However, the foods recommended in this diet may be quite expensive for many people.

And although there are several advantages of Atkins diet, make sure to consult a doctor or registered dietitian before getting started with the diet as there are some potential downsides as well.
