Low Carb Diet: Fat Loss and Metabolic Health

Nutrition science has changed a lot in recent years. No longer do we just ask How many calories?  We now ask How do hormones and metabolism respond to what we eat?

Low Carb Diet is right at the center of this debate.

From fat loss clinics to metabolic health studies carbohydrate restriction has been thoroughly researched for its impact on insulin, fat burning, blood sugar and heart health markers. Today it is widely accepted as a powerful solution for fat loss, metabolic health and energy stability.

In this in depth guide we'll discuss how a Low Carb Diet works who benefits the most from a Low Carb Diet what the science says about a Low Carb Diet and how you can use a Low Carb Diet for safe and effective fat loss.

What Is a Low Carb Diet?

A Low Carb Diet is a carbohydrate restriction diet that emphasizes protein, fat and vegetables.

What does that mean for carbs?

• Carbs are restricted to 20 to 50 grams daily (Very Low Carbohydrate or Ketogenic Diet)
• Carbs are restricted to 50 100 grams daily (Moderate Carbohydrate Restriction)
• Carbs are restricted to 130 grams daily (Low Carbohydrate Diet)

To give you a reference point  a typical Western diet contains 250 to 300 grams of carbs daily.

What Is the Purpose of a Low Carb Diet?

A Low Carb Diet isn't just for fat loss. It's for decreasing insulin and increasing fat burning.

How Does a Low Carb Diet Cause Fat Loss?

The thing is fat loss is not just about reducing the food that you eat; it is about accessing your fat reserves properly. A Low Carb Diet works in the following ways:

Insulin Reduction and Fat Burning

The hormone that is responsible for fat storage is insulin. The more carbohydrates you eat the more insulin is produced by the body. Thus when you eat fewer carbohydrates it means that you will have:

• Lower insulin levels.
• More fat is mobilized.
• More fat is used for energy.
• More fat reserves are used for energy.

Studies published in credible nutrition journals have shown that individuals who used the Low Carb Diet have more fat loss compared to individuals who used the low to fat diet especially for individuals who have insulin resistance.

Appetite Regulation and Satiety

Protein and fat help regulate the level of satiety hormones such as GLP1 and peptide YY.

When you use the Low Carb Diet you will experience:

• Less hunger.
• Less craving.
• Less snacking.

Individuals who used the Low Carb Diet have fewer calories consumed, according to clinical studies.

Improved Metabolic Flexibility

The body is more efficient in burning glucose and fat for energy.

When you use a very low carbohydrate diet the liver will produce ketones, thus fat oxidation occurs.

In the future, the Low Carb Diet can improve the metabolism of the body.

Low Carb Diet and Metabolic Health

The term metabolic health is defined by blood sugar, insulin resistance, lipid, blood pressure and inflammation.

Blood Sugar and Insulin Sensitivity

When the level of carbohydrates in the diet is low the level of blood sugar is also low.

When employing the Low Carb Diet research has found that:

• Blood sugar is lower.
• In people with type 2 diabetes, HbA1c is lower.
• Insulin resistance is lower.

Under some structured Low Carb Diets it has been found that the motivated individual can achieve partial remission from diabetes.

Triglycerides and HDL Cholesterol

One of the most consistent findings is that triglycerides are lower.

When low fat diet and Low Carb Diet interventions are used it has been found that low carb diets have a greater effect in reducing triglycerides than low fat diets.

Significant increases in HDL (good cholesterol)

These changes are powerful indicators of improved cardiometabolic health.

LDL Cholesterol: Context Matters

 In some individuals it has been found that the level of LDL cholesterol is increased.

However research has found that:

• The size of the LDL particles is increased to larger less dense particles
• The triglyceride to HDL ratio is improved

Context is everything. It is strongly recommended that you get your levels checked with the help of a healthcare professional.

Who Benefits Most From a Low Carb Diet?

Although not essential the Low Carb Diet seems to benefit the following groups in particular:

• Individuals with insulin resistance
• Individuals with metabolic syndrome
• Individuals with abdominal obesity
• Individuals with prediabetes and type 2 diabetes
• Women with PCOS

For individuals with insulin resistance the low carb diet will help them achieve results faster.

Veg Low Carb Diet: Is It Possible?

However the following modifications would allow you to restrict carbohydrates in a vegetarian diet.

• Protein Sources for a Veg Low Carb Diet
• Paneer or cottage cheese
• Greek yogurt
• Toffu and tempeh
• Nuts and seeds
• Eggs (for an ovo vegetarian)

A well planned veg low carb diet would also contain vegetables such as spinach, zucchini, cauliflower and bell peppers.

Dietary fiber is also important in the digestion of food. Chia seeds, flax seeds and leafy vegetables would provide the required dietary fiber.

However since the vegetarian diet lacks the required amino acids, protein powder is used in a low carb diet.

Role of Protein in a Low Carb Diet

Protein is an important component in a low carb diet. Protein would help you retain your muscles and would also keep you satisfied.

The daily protein requirement is between 1.2 and 2.0 grams of protein per kilogram of body weight.

Protein Powder for Low Carb Diet

The protein powder used in a low carb diet should contain the following:

• Minimum sugar content
• Minimum carb content
• Presence of amino acids

The protein powder could be whey protein isolate, pea protein powder or egg white protein powder.

Low Carb Diet Protein Shake

Low carb diet protein shake could be used for the following purposes:

• Post workout protein supplement
• Meals
• Convenience food on busy days

Unsweetened almond milk

• 1 scoop protein powder for low carb diet
• Spinach
• Chia seeds
• Ice

The low carb diet protein shake is a healthy alternative because it does not contain carbohydrates.

A low carb protein shake mix may be used tactically to ensure that muscle mass is retained during a low carb diet.

Comparing Low Carb Diet With Other Diet Programs

Low Carb Diet vs. Low Fat Diet

From comparative studies it has been found that:

• Similar weight loss is achieved by both diets after 12 months.
• Greater improvement is seen in triglycerides with the Low Carb Diet.
• Greater satiety is seen with the Low Carb Diet.

Greater weight loss is seen with the low carb diet than with the low fat diet during the first few months because of the restriction of carbohydrates for rapid weight loss.

Low Carb Diet vs. Mediterranean Diet

Both diets recommend the use of whole foods in the diet.

In addition the Mediterranean diet recommends that grains and legumes be included in the diet.

In contrast the low carb diet restricts the use of grains and legumes in the diet because of the regulation of insulin.

Low Carb Diet Desserts: Are They Safe?

Many people fear that they may lose their favorite desserts.

However good news is here because low carb diet desserts may be prepared with the following ingredients:

• Almond flour
• Coconut flour
• Stevia or Erythritol
• Dark chocolate (85%+)

Low carb diet desserts may be low carb cheesecakes, chia pudding, flourless chocolate muffins etc.

Low carb diet desserts are a welcome addition because there is no restriction with regard to flexibility.

Practical Implementation of a Low Carb Diet

Starting a Low Carb Diet

Step 1: Remove Refined Carbohydrates

Eliminate the following from the diet:

• Sugary drinks
• White bread
• Pasta
• Pastries

Step 2: Focus on Whole Foods

Emphasize the following whole foods:

• Eggs
• Fish
• Meats
• Non starchy vegetables
• Olive oil
• Avocados

Step 3: Monitor Electrolytes

Carbohydrate restriction may cause water loss in the first week.

To avoid fatigue or low carb flu the diet should also include:

• Sodium
• Potassium
• Magnesium

Sustainability and Long Term Success

Success depends on compliance.

A Low Carb Diet should not be restrictive.

Strategies for success:

• Meal prep once a week
• Use low carb diet desserts
• Use low carb diet protein shake
• Use waist circumference instead of weight

Common Mistakes on a Low Carb Diet

• Lack of protein
• Excessive consumption of "low carb" products
• Lack of fiber
• Lack of monitoring cholesterol

A balanced low carb diet is better than a processed low carb diet.

Real World Example

A 45 year old person has the following medical test results:

• Fasting glucose level: 115 mg/dL
• Triglycerides: 220 mg/dL
• Waist circumference: 40 inches

After 6 months of a structured low carb diet the person has the following test results:

• Fasting glucose level: 95 mg/dL
• Triglycerides less than 150 mg/dL
• Waist circumference reduced by 3 to 4 inches

These test results mirror those of a clinical study.

Safety and Medical Considerations

A Low Carb Diet is generally safe for an average adult, but it is recommended that an individual with:

• Insulin dependency
• Blood pressure medication
• Kidney diseases seek medical supervision

Adjustments may be necessary.
