Keto Advantage: Effective Belly Fat Burner?

Belly fat is linked to serious health conditions such as heart disease, type 2 diabetes, stroke, and cancer. A ketogenic (keto) diet is a popular way to lose weight and burn belly fat. It is a high-fat, low-carbohydrate diet that forces the body to use fat as its primary fuel source instead of glucose. This state is called ketosis. While a keto diet has been proven to be effective for weight loss, it can be challenging to maintain. This paragraph will discuss the keto diet's advantages and disadvantages for reducing belly fat.

Cut out sugar

Sugar is a major contributor to belly fat. Fructose, in particular, is the biggest offender for the steadily rising amounts of abdominal fat. Brenda Rea, MD, DrPH, PT, RD, a family and preventive medicine physician at Loma Linda University Health, explains that sugar can create an inflammatory response in the body, putting the body in a stressed-out state. This inflammatory response and stress cause the body to store fat in and around the belly.

Sugar and refined carbs also spike insulin levels in the body, which signals the body to store fat. When we eat refined carbohydrates, they are quickly absorbed into the bloodstream. In response to this spike in sugar, the pancreas releases a lot of insulin to manage it. Insulin moves the sugar from the bloodstream into cells to prevent damage to blood vessels and organs.

Fructose causes cellular inflammation, which boosts cortisol levels and causes stored fat to move from subcutaneous fat cells to visceral fat storage. Sweetened drinks (such as sodas, which include high-fructose corn syrup) and table sugar, which contains 50% fructose, are the most popular sources of fructose. Research indicates that eating sugary meals and drinking sweetened drinks raises ectopic and belly fat levels.

It is important to be aware of hidden sugars in foods. High fructose corn syrup, cane sugar, cane juice, molasses, raw sugar, turbinado sugar, malt syrup, and date sugar are some of the most common hidden sugars. Foods like granola bars, ketchup, yogurt, and breakfast cereals may also contain hidden sugars. Reading labels and looking for alternative names for sugar can help identify these hidden sugars.

Cutting out sugar can be an effective step towards reducing belly fat. It is important to note that there is no "one-trick" solution, and a combination of dietary and lifestyle changes may be necessary for significant results.

Exercise

Benefits of Exercise on the Keto Diet

The keto diet is a low-carb, high-fat diet that can be highly effective for weight loss, including belly fat loss. Exercise can further enhance the benefits of the keto diet. Combining the keto diet with regular exercise is a great way to get your belly fat under control and maintain a healthy level of fats in your body.

Types of Exercise to Reduce Belly Fat

Not all exercises are created equal when it comes to belly fat loss. Here are some specific types of exercise that can help reduce belly fat:

• Aerobic Exercise (Cardio): This type of exercise is particularly effective for decreasing visceral fat levels. A 2018 meta-analysis found that aerobic exercise effectively decreases belly fat in overweight adults, even without cutting calories. Walking every day can be a great way to start incorporating aerobic exercise into your routine.
• High-Intensity Interval Training (HIIT): HIIT involves short bursts of intense activity followed by brief periods of rest. While there is less research on HIIT specifically for belly fat loss, at least one study found that it was as effective as steady-state cardio and more time-efficient.
• Weight Training and Resistance Exercises: These types of exercises can help burn belly fat by reducing inflammation levels, retaining muscle mass as you age, and changing the way your body distributes fat in a healthy way. Combining weight training with cardio is the best way to retain muscle mass while burning fat.

The intensity and frequency of your exercise routine can also impact the effectiveness of belly fat loss. Moderate to high-intensity aerobic or resistance exercises tend to show the best results. For example, a study found that postmenopausal women who did aerobic exercise for 300 minutes per week lost more fat from all areas compared to those who exercised for only 150 minutes per week.

Combining Exercise with the Keto Diet

When it comes to reducing belly fat, combining the keto diet with regular exercise can be a powerful approach. The keto diet helps reduce hunger, lower blood sugar levels, and prevent insulin spikes, all of which contribute to belly fat loss. Additionally, the keto diet forces your body to burn fat for fuel, both during exercise and at rest. By incorporating exercise into your keto diet, you can accelerate belly fat loss and improve your overall health.

High protein intake

A high protein intake is an effective way to lose weight and belly fat. Protein boosts metabolism, reduces appetite, and changes levels of several weight-regulating hormones.

According to the National Academy of Sports Medicine (NASM), you should eat between 1.6 and 2.2 grams of protein per kilogram of body weight per day if you're aiming for overall weight loss. The Dietary Reference Intake (DRI) for protein is 46 grams for the average woman and 56 grams for the average man, but this may not be optimal for weight loss. Most studies on protein and weight loss recommend getting 30% of your calories from protein. For a 2,000-calorie diet, this would mean consuming around 150 grams of protein per day.

Protein works in several ways to support weight loss. Firstly, it increases your levels of the satiety (appetite-reducing) hormones GLP-1, peptide YY, and cholecystokinin, while reducing your levels of the hunger hormone ghrelin. This leads to reduced hunger and increased feelings of fullness, making it easier to eat fewer calories without feeling deprived.

Secondly, protein has a high "thermic effect," meaning that your body uses more calories to digest and metabolize it compared to carbohydrates or fat. This effect is particularly pronounced when you're in a calorie surplus, further boosting your metabolism and increasing the number of calories burned.

Thirdly, protein helps prevent muscle loss when you're losing weight. When people lose weight, they often lose muscle mass as well as fat. However, eating plenty of protein, especially when combined with strength training, can help preserve muscle mass and keep your metabolic rate high.

High-Protein Foods

• Eggs: A versatile and inexpensive source of lean protein.
• Lentils: A legume that is high in both protein and fiber, making it ideal for weight loss.
• Edamame: A nutritious plant-based protein that is high in vitamins and minerals.
• Tempeh: A soy-based food that is satisfying and good for the gut.
• Lean meats: Skinless chicken, turkey, pork loin, bison, and fish are low in calories and processed ingredients while being high in protein.
• Chickpeas: A plant-based complete protein that is high in fiber and essential amino acids.
• Quinoa: A whole-grain complete protein that is high in plant-based protein and supports metabolism.
• Black beans: A gluten-free, plant-based complex carbohydrate that is high in protein and fiber.
• Dairy products: Low-fat Greek yogurt, cottage cheese, and fat-free milk are high in protein and calcium, which can speed up metabolism.
• Whey protein: Found in dairy products, it contains all the essential amino acids and is particularly effective for muscle growth.

Avoid 'dirty keto'

The keto diet is a very low-carb, high-fat diet that has been proven to help burn belly fat. However, not all keto diets are created equal. "Dirty keto" is a slang term for a ketogenic diet that ignores food quality and focuses solely on the macronutrient breakdown, aiming to keep carbs low to induce a fat-burning state called ketosis. While a dirty keto diet may help with weight loss, it comes with several drawbacks and negative long-term health effects. Here are some reasons why you should avoid dirty keto:

Inflammatory Vegetable Oils

Dirty keto often includes a group of fats known as vegetable oils, such as soybean oil, safflower oil, sunflower oil, and canola oil. These oils are high in omega-6 polyunsaturated fat (PUFA), specifically linoleic acid. While small amounts of linoleic acid are healthy, excessive consumption is believed to contribute to obesity and inflammatory conditions that drive fat storage. Additionally, cooking with vegetable oils at high heat can create compounds linked to heart disease.

Micronutrient Deficiency

Dirty keto plates often lack low-carb vegetables, which are rich sources of vitamins and minerals. Non-starchy veggies like spinach, kale, asparagus, broccoli, and cabbage provide essential nutrients like folate, vitamin A, vitamin C, calcium, magnesium, and potassium. Folate, for example, is crucial for energy production, nervous system health, cardiovascular support, and reproductive health. By avoiding these nutrient-dense foods, you may experience deficiencies and related health problems.

Lack of Fiber

Avoiding vegetables on a dirty keto diet also means missing out on fiber, which is important for bowel regularity and a healthy gut microbiome. Fiber is indigestible by normal routes but can be broken down by gut bacteria, producing anti-inflammatory compounds.

Increased Sodium Intake

Dirty keto meals tend to be high in sodium, which can be problematic for individuals sensitive to salt. High sodium intake is associated with high blood pressure and an increased risk of heart disease.

Consumption of Additives and Processed Foods

Dirty keto often includes highly processed and packaged foods that contain additives and fewer micronutrients. These processed foods are associated with negative health effects, including weight gain, diabetes, overall mortality, and heart disease. Certain additives, such as trans fats, are linked to adverse conditions like cancer, obesity, and type 2 diabetes.

Lack of Micronutrients

Dirty keto foods are often lacking in essential vitamins and minerals that your body requires, such as calcium, magnesium, zinc, folic acid, and vitamins C, D, and K. While supplements can provide these nutrients, studies suggest that your body absorbs and utilizes them better from whole foods.

In summary, while dirty keto may help with weight loss by keeping carbs low, it does so at the cost of your long-term health. To maximize the benefits of the keto diet, it is best to focus on nutrient-dense whole foods and minimize the consumption of processed items. Opt for "clean keto," which emphasizes high-quality, nutritious, and locally sourced foods while still maintaining the desired macronutrient profile.

Genetics and muscle shortening

The ketogenic diet is a low-carb, high-fat diet that has been proven to be effective for weight loss. It is superior to a high-carb diet and may even provide a "metabolic advantage". The diet is also very effective in helping to lose belly fat, which is a serious risk factor for metabolic diseases such as type 2 diabetes, heart disease, and premature death.

Genetics plays a role in where we store fat and where we lose it. It is also a factor in how our abdominal muscles shorten following the loss of internal fat. For example, if you lose 6 inches off your waist, your abdominal muscles will need to shorten by a few inches. This process takes 6-12 months to occur naturally and, in the meantime, your belly will look soft.

Genetics also plays a role in muscle stiffness and shortening. Muscle stiffness is thought to be one of the risk factors associated with sports injuries and is less common in females than in males. These observations may be explained by circulating levels of sex hormones and their specific receptors. It has been shown that higher levels of estrogen are associated with lower muscle stiffness responsible for the suppression of collagen synthesis. It is thought that these properties, at least in part, depend on genetic factors.

The gene encoding estrogen receptor 1 (ESR1) is one of the candidates that may be associated with muscle stiffness. The ESR1 rs2234693 C and the rs9340799 G alleles have been linked to increased gene expression and more beneficial estrogen-induced effects. The presence of these alleles might be associated with lower muscle stiffness.

The collagen type V alpha 1 chain gene (COL5A1) is also a promising candidate gene variant that may be recognized as a muscle injury risk factor and may also affect muscle stiffness and joint flexibility.

The alpha-actinin-3 gene (ACTN3) is a common single nucleotide polymorphism (SNP) that was discovered in 1999 when searching for possible causative genes for muscular dystrophy. Homozygosity for the 577X allele (577XX genotype) results in a complete deficiency of the sarcomeric alpha-actinin-3. The lack of functional alpha-actinin-3 is not detrimental to the 577XX homozygotes in terms of disease, but it alters muscle function and metabolism.

The ACTN3 R577X SNP has been studied in relation to athletic performance, and it was shown that the RR genotype was overrepresented in sprint-power athletes, while the frequency of the XX genotype was higher in endurance athletes. Effects of the ACTN3 R577X polymorphism on the athletes' lower-extremity power output have been measured, and the best results were registered in athletes with the R allele or RR homozygotes rather than in alpha-actinin-3 deficient individuals.

In summary, genetics plays a role in muscle shortening and stiffness, and certain genes and gene variants have been identified as contributing factors.
