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.

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. 

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.
