About L-Carnitine

Taking L-Carnitine is known to:

  • Improve high-intensity work capacity
  • Increase athletic performance
  • Speed your recovery from intense exercise
  • Make your brain work better

Carnitine is an amino acid composite that is made of lysine and methionine. It is responsible for the transport of fat into the cells to be used for energy, therefore your body becomes more efficient in processing fuel and it will increase your energy levels.

Elevating carnitine will improve physical performance by burning more fat, sparing glycogen, clearing muscle lactate, and optimizing hormone levels.

For Carnitine to be effective, you need to make sure you have enough Omega-3 in your body. Omega-3s increase metabolic rate by increasing cell activity and fat burning. Carnitine is the delivery system for long chain fatty acids therefore the less carnitine you have in your body, the fewer fatty acids get into the cells, and you don’t burn them for energy. Instead they’re stored as fat. By elevating carnitine fat burning increases, you will have more energy and feel more motivated.

Carnitine fights visceral belly fat, that is known to be the toughest fat to loose. Raising your carnitine levels will fight this visceral belly fat gain because it increases fat burning.

Higher muscle carnitine levels help decrease pain, muscle damage and markers of metabolic stress from high intensity exercise by reducing lactic acid production, therefore you can have a greater work production because it will not feel as physically difficult.

Taking carnitine will also support an anabolic response to exercise by up-regulating the androgen receptors, which will speed up your recovery.

Carnitine can help prevent type 2 diabetes because of how it improves fat metabolism. It can counter the diseases of metabolic syndrome by supporting cardiovascular health while inducing fat loss.

My message for beginners

A short video for those of you who contacted me on social media asking me questions about how to lose weight or get bigger.

Why too much sugar is bad in your diet

Added sugars, like high fructose corn syrup and sucrose, contains a lot of calories with no essential nutrients. That’s why they’re called empty calories.

There are no proteins, essential fats, vitamins or minerals in sugar – only calories.

Sugar is the leading contributor to obesity in both adults and children. People who consume a lot of sugars are more likely to become obese, and this applies to all age groups.

Sugar is very easy to overeat. Some nutrients make us feel fuller for longer, therefore we eat less within a 24 hr period. Protein and fiber are known for their satiating properties, but sugar isn’t. In fact, foods and drinks high in added sugar are extremely easy to over-consume. Sugar-sweetened beverages are the worst because even though they’re high in calories, your brain doesn’t register them like solid food. So you won’t eat less food to compensate for those calories.

Sugar can contribute to insulin resistance, that can cause serious metabolic problems. Insulin is a very important hormone when it comes to weight loss. It allows blood glucose (blood sugar) to enter cells to be utilized for energy. Too much glucose left in the blood can cause complications, like diabetes, kidney damage or blindness.

Insulin resistance is when cells become resistant to insulin which means it stops working as it should. Insulin resistance is believed to be the major cause for metabolic diseases.

Sugar also causes tooth decay. When we eat sugar, the harmful bacteria in the mouth can use it for energy. This allows them to grow, multiply and secrete acids that erode the protective enamel of the teeth. Sugar alcohols are popular alternatives that may help protect the teeth.

What you can do if you would like to lose weight is to cut back on added sugars in your drinks and foods. If you miss the sweet taste, you can use certain natural sweeteners to cure your cravings.

About refined carbs

Not all carbs are created equal. There are lots of whole foods that are high in carbs but still incredibly healthy and nutritious.

And there are refined or simple carbs, that have most of their nutrients and fibers removed. Eating refined carbs can lead to many illnesses including obesity, heart disease and type 2 diabetes.

So what are refined carbs?

There are 2 types of refined carbs:

  • Sugars, like high fructose corn syrup and table sugar
  • Refined grains: grains that have their nutritious and fibrous part removed. The biggest source is white flour made from refined wheat.

Refined carbs have been stripped off most of their fiber and vitamin content therefore they are considered empty calories. They also absorb quickly in the bloodstream, therefore they have a high glycemic index (GI).

Sugars and refined carbs are a very large part of the total carb intake in many countries.

The main sources of refined carbs are: white pasta, white rice, white flour, white bread, pastries, sodas, snacks, sweets, breakfast cereals and added sugars.

Because refined carbs are low in fiber and digested quickly they cause major swings in blood sugar levels. Foods with high GI promote short term fullness, lasting for about an hour. Low GI foods promote long term fullness, lasting for 2-3 hours. Blood sugar levels drop after about 1-2 hrs eating refined carbs. This promotes hunger and stimulates cravings. When you crave food, you’re prone to overeating.

Refined carbs can cause inflammation in the body which could be the primary cause of obesity and leptin resistance.

Studies show that a high consumption of refined carbs is linked with insulin resistance and high blood sugar levels. These are the main symptoms of type 2 diabetes. Refined carbs also increase blood triglyceride levels which is a risk factor for both heart disease and type 2 diabetes.

However not all carb foods are bad. There are many foods that contain healthy carbs because they’re great sources of fiber, vitamins and minerals. These include:

  • oats
  • buckwheat
  • quinoa
  • bananas
  • sweet potatoes
  • beetroot
  • oranges
  • blueberries
  • grapefruits
  • apples

Tips on how to avoid putting on fat during Xmas

Xmas is coming fast and when the family and friends gather together it’s always accompanied by food and drinks. It’s a celebration, isn’t it? More often than not the food is not a healthy one and you might start panicking what to do to not to put on weight this season. Here are a few tips that might help you:

Stay active! Just because it’s Xmas it doesn’t mean everything stops – apart from your metabolism, that might stop if you are not active and overeat. Some of the gyms are open during xmas time, and even if yours is not, you can always go for a walk – slow or fast – after your meal or in the evening.

Get more Vitamin D3: If there’s no direct sunshine where you live – especially here in the UK, get some Vitamin D3 supplements. Vitamin D3 contributes to the normal function of the immune system and healthy inflammatory response and to the maintenance of normal muscle function.

Eat more protein and veggies: meat and vegetables/fibre help keep blood glucose and insulin levels down, help you burn fat and keep you from getting sick. Not to mention that they will make you feel full, too so you might eat less carbs.

Lower your sugar and carb intake: with the plates full with processed food and sugars/simple carbs, the single most effective thing you can do is watch your portion size of these foods. Don’t have a whole slice of cake, try only a bite. Don’t have a whole plate of pasta or other high carb food, try just a spoonful. If you watch your portion sizes you can probably try most of the xmas foods without being sick afterwards or feeling guilty for eating too much of them.

For athletes: 9 science based ways to lose weight

Recently I’ve come across an article that talks about 9 science-based ways for athletes to lose weight. When you think about it, it’s always more difficult to lose weight when you’re always training, always eating clean. Humans need a certain amount of bodyfat to maintain basic functions. Too much bodyfat – however – can negatively affect an athlete’s performance. So what can athletes do to ‘step up’ their weight loss to be in prime condition and shape?

  1.  The first point this article suggests is to lose weight off season. We are talking about b athletes in general. It does make sense to try and lose the excess bodyfat offseason because it’s very difficult to reach peak fitness while dieting. When you’re not eating enough calories, your athletic perfomance will suffer. Losing weight offseason will give you more time to lose the excess bodyfat as well, so that you don’t have to rush the fat loss and can stick to the healthy pace of 0.5 kg / week – minimising the muscle loss.
  2. Avoid crash diets. I think we don’t really need to prove this point, athletes know that they need a certain amount of calories to be able to perform at the training sessions. Also drastically reducing your caloric intake will affect your metabolism and hormonal balance. Athletes should only cut their calories by no more than 300-500 kcal a day.

  3. Eat less sugar and more fibre. Low carb diets are proven to be the best for fat loss. However restricting the carb intake too much will affect your athletic performance. To reduce the carb intake cut out added sugars, and avoid cane juice, dextrin, maltodextrin, barley malt, caramel, fruit juice concentrate, fruit juice crystals and any type of syrup. Instead increase your intake of vegetables high in fibre.

  4. Increase your protein intake. Protein promotes fat loss in several ways: high protein diets increase feelings of fullness and the number of calories burnt through digestion. High protein diets also prevent muscle loss during periods of weight loss. Therefore athletes restricting their calories to lose weight should eat between 1.7 – 2.8 gr protein / kg of bodyweight / day.

  5. Spread protein intake throughout the day. 20-30 gr protein per meal is sufficient to stimulate muscles to produce protein for the following 2-3 hrs. Eating a snack containing 40 gr protein before bed can increase muscle protein synthesis during night. This may help prevent some of the muscle loss expected during sleep.

  6. Refuel well after training. Eating the right foods after competing or training is very important for the athletes, especially when trying to lose bodyfat. Proper refuelling is very important especially on days when you have more than 1 events with less than 8 hours recovery time. Carbs with protein can speed up recovery time and promote protein production in your muscles.

  7. Strength training can also help holding on to the muscle when trying to lose bodyfat. Research shows that both protein intake and strength training stimulate muscle protein synthesis and combining the two can produce an even better effect.

  8. After your diet, increase your calories gradually. It may be tempting to start eating normally again after you’ve reached your desired body fat percentage, but that would lead you to gain bodyfat back. Gradually increasing your caloric intake can help restore your hormone levels and metabolism better, minimizing the weight gain.

  9. Here are some other ways you can achieve weight loss:

    • measuring your portions and keeping track of what you eat is scientifically proven to help you get better results.
    • drinking before consuming a meal can help you consume 22% less calories
    • eat slowly, aim to take at least 20 mins for a meal
    • avoid alcohol
    • get enough sleep, not enough sleep can increase hunger and appetite by 24%. Not getting enough sleep will also affect your athletic performance.
    • reduce your stress. Having high stress levels will increase cortisol levels which promotes food cravings and drive to eat. Mental and physical stress can also prevent proper recovery.

About Creatine

Creatine is a protein that is naturally made of 3 amino acids: arginine, glycine and methionine. It can also be found in meat and fish, and can be taken as a supplement.

Creatine combines with phosphorus to form phosphocreatine (PC) in the muscle cells. This fuels your muscles during high intensity training, such as sprinting or lifting weights. Creatine raises PC levels around 2%, which means you can sustain all out effort for longer and recover faster between sets.

Protein promotes muscle hypertrophy and protein manufacture. Lot of studies show that short-term creatine supplementation increases body mass. Studies found that creatine supplements improved strength, the number of repetitions performed to fatigue, and the ability to perform repeated sprints.

How does creatine work?

The gains observed are partly due to the increase of cell volume and partly muscle synthesis.

Creatine cause water to move across cell membranes. When muscle cell creatine concentration goes up, water is drawn into the cell an effect that boosts the thickness of muscle fibres by about 15%. The water content of muscle fibres stretches the cell’s outer sheaths.

In aerobic sports there is less evidence for creatine use. This is probably due to the fact the PC energy system is less important during endurance training.

Who should use it?

If you train with weights, or do any sports that includes high-intensity movements (sprints, jumps or throws: rugby, football, hockey, gymnastics, tennis etc), creatine supplements may help increase your performance, strength and muscle mass.

Taking carbs with creatine can be beneficial, as carb intake increases insulin which helps creatine uptake by the muscle cells.

Creatine monohydrate is the most widely available form of creatine. It comprises a molecule of creatine with a molecule of water attached to it. It requires a loading phase. One way to do it is to take about 20-25 gr / day in 4-5 doses for 5 days. After the loading phase the dosage is 2 gr / day.

The side effects of Creatine:

The main side effect is weight gain. This is partly due to the extra water in the muscle cells, and party to increased muscle tissue. It could be disadvantageous in sports where there’s a critical ratio of bodyweight and speed (like running), or in sports where there are weight categories.

About L-Carnitine

L-Carnitine is one of the naturally occurring amino acids. It is often used as a weight loss supplement. It transports the fatty acids into the cells’ mitochondria where it gets burnt off to use as energy. Your body can produce L-Carnitine from the amino acids lysine and methionine. You can also obtain small amount of L-Carnitine from your diet by eating meat or fish.

L-Carnitine L-Tartrate is the most common form of L-Carnitine that is used in most sport supplements, because of its fast absorption and it may help with muscle soreness and recovery.

In human studies, taking acetyl-L-carnitine daily helped reverse the decline in brain function associated with Alzheimer’s and other brain diseases.

Some studies have demonstrated a potential benefit for reducing blood pressure and the inflammatory process associated with heart disease.

L-carnitine may benefit:

Recovery:It may improve exercise recovery.

Muscle oxygen supply: It may increase oxygen supply to the muscles

Stamina: It may increase blood flow and nitric oxide production, helping delay the “burn” and reduce fatigue

Muscle soreness: It may reduce muscle soreness after exercise

Red blood cell production: It may increase the production of red blood cells, which transport oxygen throughout your body and muscles.

L-carnitine has also been shown to reduce symptoms of type 2 diabetes and its associated risk factors.

The main foods high in L-Carnitine are:

  • – beef
  • – pork
  • – fish
  • – chicken
  • – milk

 L-Carnitine has a greater absorption rate from food than from supplements.

Doses of 2 grams or less per day seem to be well tolerated and safe for most people. Some people have reported nausea or other digestive side effects, but no serious issues have been found.

About caffeine

Caffeine was once classed as a banned substance but was removed from the World Anti-Doping Agency prohibited list in 2004. Caffeine is a stimulant and has pharmacological action on the body therefore is classed as a drug rather than a nutrient.
Caffeine is found in everyday drinks and foods, such as coffee, black tea, green tea, cola, herbs such as guarana, both dark and white chocolate and it is added to a number of energy drinks and sports drinks and gels. 
Caffeine acts on the central nervous system, increasing alertness and concentration. These effects reduce the perception of fatigue and allow exercise to be maintained at a higher intensity for a longer period. 
Large number of studies show that caffeine intake can enhance performance at doses of 1-3mg/kg. There appears to be little increase in performance above 3mg/kg. for a 70kg person, this would be 210mg = 2 cups of coffee or 2 cans of caffeinated energy drinks.
Performance benefits occur soon after consumption, so caffeine may be consumed just before exercise, spread throughout exercise or late in exercise as fatigue is beginning to occur.
Although caffeine is a diuretic, a daily intake of less than 300mg caffeine results in no larger urine output than water. Taking caffeine regularly builds up your caffeine tolerance so you experience smaller diuretic effects.
Caffeine consumption likely causes a short-term spike in blood pressure after consumption, with the spike being more pronounced in those who don’t normally ingest caffeine and in those with hypertension. However, the evidence concerning the long-term effects of caffeine and caffeinated beverages on blood pressure is mixed.
Caffeine may raise eye pressure, but only in those who have pre-existing eye conditions like glaucoma.
Coffee contains oily substances called diterpenes, and the 2 main types are cafestol and kahweol that increase the cholesterol levels. Coffee filters trap most of the cafestol and kahweol though, so instant or filter coffee don’t contain much of these, only boiled coffee. 

Soy: good or bad?

Soy contains 26% protein. It has the highest protein content amongst the plants. It is also the highest quality protein amongst the legumes.
Grains are typically low in lysine, beans are typically low in sulfur, methionine and cysteine. However the level of sulfur amino acids is higher in soy than in other beans.
Soybeans are high in fats, too. Most legumes (except peanut) contains 2-14% of fat, soy contains 31% of fat. Most fats in soy is unsaturated.
A serving of soy provides about 8 gr of dietary fibre. However some soy foods are processed in a way that decreases the fibre content, like tofu or soy milk. Processing soy at a high temperature can denature some of the proteins and reduce their quality.
Soy provides important nutrients: calcium, vitamin B12, iron, magnesium and selenium.

Interestingly, whole soybeans are rarely consumed in Western countries. The majority of soy in the diet comes from the refined products that are processed from the soybeans.

The fatty acids in soybeans are mostly Omega-6 polyunsaturated fats. This can be problematic because too many Omega-6s in the diet can lead to inflammation and all sorts of health issues. For this reason, it is very important to avoid soybean oil (and other vegetable oils high in Omega-6) and processed foods that contain it.

The nutrition composition of soy products depends on the type of soy food. Refined soy products, like soy protein and soy bean oil might not be that nutritious at all.

There is some evidence that soy can lower cholesterol levels, although studies show conflicting results. Men who consume soy are at a lower risk of developing prostate cancer in old age.

Soy contains large amounts of biologically active compounds called isoflavones, which function as phytoestrogens… that is, plant-based compounds that can activate estrogen receptors in the human body. These isoflavones are classified as endocrine disruptors, chemicals that interfere with the normal function of hormones in the body. The key isoflavones in soy are genistein, daidzein and glycitein. This can cause reduced estrogen activity due to the isoflavones blocking the actual, more potent estrogen from binding, or it can lead to an increased estrogen activity due to the isoflavones activating the receptors.

Animal studies show that soy isoflavones can cause breast cancer. There are also human studies showing that soy isoflavones can stimulate the proliferation and activity of cells in the breasts.
This may indicate an increased risk of breast cancer, which is the most common cancer in women.

Even though men have some amount of estrogen, having significantly elevated levels is not normal. Therefore, it seems logical that increased estrogen activity from soy isoflavones could have some effects on men. Many believe that soy can reduce testosterone levels, but the effect appears to be weak and inconsistent.

The isoflavones in soy also function as goitrogens, which are substances that interfere with thyroid function. They can inhibit function of the enzyme thyroid peroxidase, which is essential for production of thyroid hormones.

It is important for women who are pregnant, plan on becoming pregnant, or are breastfeeding, to avoid soy and other sources of endocrine disrupting compounds.
