Determining the Optimal Calorie Intake for Weight Loss

posted by admin in Food & Nutrition

If you’re trying to lose weight, you’re probably aware that your diet will greatly affect the amount of weight that you are going to lose.

Weight loss is a consequence of a simple equation:

Calories IN < Calories OUT

“Calories in” is determined through the foods that you consume, while the “calories out” is affected by a number of mechanisms, including exercise, daily activity, meal frequency, your metabolism, hormones, sleep etc.

So the focus of this article is how to determine the optimal calorie intake for weight loss, which is the left side of this equation. Obviously, the smaller your calorie intake, the greater the potential calorie deficit, which will likely lead to greater weight loss. You do however have to be careful that your calorie deficit isn’t too great, or else you risk unnecessary muscle loss, excessive fatigue and evenserious health complications.

There are a number of calculators available on the internet to determine the optimal number of calories to lose weight. However, these calculators have been developed based on the “average” person with “common” goals. Because you are an individual, with unique goals, lifestyle habits, eating preferences etc, you will have to determine a unique approach to your diet. These calculators can be used as an initial guide – but determining your optimal calorie intake for you requires much more consideration.

So where to start? Your personal trainer, dietician or nutritionist would be able to provide with a starting point based on a thorough assessment. If however you are planning to do this on your own, a calculator based on a well respected research paper may be a good starting point for your total calorie intake. Be careful – there are many calculators out there and not all of them have any credible scientific backing to justify their results. We strongly suggest that you undertake the guidance of a trained professional to advise you as to the types and quantities of food groups that constitute that total calorie intake.

You then need to put this dietary plan into practice. This is best accomplished under the guidance of a fitness professional. If however you are doing this on your own, you need to assess your body on a regular basis (weekly is a good frequency), to ascertain whether or not you are losing weight following this particular dietary approach.

If you are losing an appropriate amount of weight, then the caloric intake from that dietary plan is helping to create a calorie deficit within your lifestyle. If you are not losing weight, then chances are that you are not placing your body in a great enough deficit – so some revision may be required.

This approach is known as an empirical approach within the scientific community, where you assess the effectiveness based on results. Because your body varies so greatly due to your own individual characteristics, there is no single calculator or text book that can guarantee you an effective, healthy and safe caloric intake resulting in weight loss. You need to begin with an appropriate starting point, assess and adjust based on your weight loss results.

Though it has been mentioned a number of times throughout this article, it is worth stressing once again; if you are unfamiliar with nutrition and are unsure with the functions and importance of fats, carbohydrates, proteins, vitamins, minerals and phytonutrients within your body, you should consult with a professional to obtain guidance. While weight loss can be accomplished through a calorie deficit alone, you also have your health to consider – and it certainly is possible to lose weight through an unhealthy dietary approach.

The Best Type of Cardio Exercise for Weight Loss

posted by admin in Exercise

Although weight loss is not exclusively affected by cardio exercise alone (weights, dieting, sleep etc. will also affect weight loss), this form of exercise can have a profound effect on shedding the extra kilo’s.

Cardiovascular exercise has the unique ability to raise the heart rate substantially and increase the energy expenditure of your body for a period of time during your workout. It can also induce additional calorie expenditure after your workout has completed. Furthermore, cardiovascular exercise has the ability to improve your level of fitness, so in subsequent workouts you can expend even more energy within a given period of time.

But when it comes down to the different formats of cardiovascular exercise, what is the best type of cardio for weight loss?

If we were to consider the science exclusively, interval training has been demonstrated to result in significantly more fat oxidation (or fat loss) as compared to steady state cardiovascular exercise (or maintaining the same level of intensity for a prolonged period of time). A classic example of this was in a classic 1994 study lead by Angelo Tremblay, where it was demonstrated that a high intensity interval training cardio workout was far more effective at breaking down fat tissue, relative to an endurance based exercise group. In fact, the interval training group only exercised for a quarter of the time that the endurance group exercised at and managed to lose nine times more fat weight!

We have written a comprehensive article on this topic and if you would like to find out more about this 1994 study, please read “The Fat Burning Zone”.

Science has shown time and time again that interval training is significantly more effective for weight loss as compared to steady state exercise. Does this necessarily mean that interval training is the best cardio for weight loss?

Certainly not!

No, I am not dismissing the very conclusive science that has been conducted in this field. I whole-heartedly agree that interval training is a highly effective approach for fat oxidation. That being said, an even more important consideration is how consistently you undertake the cardiovascular exercise.

Interval training, while extremely rewarding, is physically and mentally demanding. It requires 100% effort and as such can be extremely discouraging to anyone who doesn’t particularly enjoy exercise. Interval training will only be effective if it is completed on a regular basis – as the cumulative effect of multiple cardio workouts is what results in significant amounts of weight loss. If you thrive on a challenge, then this may be for you. If however you cannot sustain a consistent approach with such a full-on exercise format, then it may be far more effective to undertake a lower intensity training regime.

Another major consideration is your fitness. If you are particularly unfit, or have minimal recent exercise experience, it is unwise to initiate training with a high intensity approach. This can place far too much physical strain on your body, resulting in a lowering of the immune system and an excessive amount of fatigue following your training session. Doing “too much” can be quite counterproductive, so it is important how capable your body is of handling the physical workload that you wish to subject it to.

When it comes down to the best cardio for weight loss, you need to be smart and be consistent. Sporadic workouts are not going to yield fantastic results. Doing too much (or too little) is also not going to result in an optimal degree of weight loss.

Begin with a moderate approach if you do have limited exercise experience and then gradually increase the intensity as your fitness improves. A gradual approach is generally more effective in regards to sustainability and thus long-term and significant weight loss.

Weight Loss and Bodybuilding Supplements – Advertisements, Hype and False Hopes

You’ve probably been subjected to a weight loss or bodybuilding supplement advertisement implying that you could obtain a phenomenal transformation if you were to purchase that particular product. Claims such as “Lose 10kg in 3 weeks” or “Gain 5kg of muscle in a fortnight” are not a stranger to the weight loss and bodybuilding marketing industry.

It is quite possible are that you are going to be relatively impressionable when watching such an advertisement, particularly if you’re not overly familiar with the industry. We are naturally driven by the desire to be happy – and attaining an “ideal” body is often associated with a heightened sense of fulfilment. So, a product that almost promises guaranteed accomplishment of your ultimate goal can sometimes be far too emotionally driving to resist, even if the claims seem a little too good to be true. It’s no wonder that the dieting industry is a multi-billion dollar industry. Bodybuilding supplementation advertisements also draw upon the same emotional response as the weight loss supplements do.

But just how true are these supplement advertisements and should you trust them? Well “technically speaking”, they are true – otherwise those ads would be deemed as false advertising. Though, many are very misleading as a result of a highly subjective presentation. Let’s consider two typical examples; one in each of the bodybuilding and weight loss supplementation arena’s.

The supplement ad that claims that you will gain 600% more lean mass. Often a claim like this will be highlighted and a highly subjective article will follow. The first obvious misconception about such a statement is that “lean mass” is muscle – this is incorrect. Lean mass refers to fat free tissue. Often a gain in lean mass can be attributed to an increase in fluid retention, for example. Next, we must question 600% more lean mass relative to what? Was it compared to a placebo? Delving deeper, you should then ascertain exactly how this claim was determined – was this via an objective third-party independent study, or was this conducted by the supplement company itself?

The statement “Lose 5kg in 5 days!” Such a phrase implies that you will lose 5kg of fat in 5 days, but this is not correct. The statement suggests that 5kg of body mass can be lost in 5 days. This is not necessarily fat tissue – this could be muscle and/or fluid weight as well. Especially in the early stages of dieting, significant weight loss is common due to a reduction in fluid retention in particular.

You could analyse almost any claim and subsequently identify that there is often a lot of “hype” associated with many of the marketing campaigns in this industry. Ultimately statements can often be quite misleading and it is your responsibility to understand exactly what is being said.

Now please don’t misunderstand – supplements are of great value in aiding you in accomplishing your health and fitness goals – otherwise we would not sell them in our supplement store. When used in an appropriate manner, they can assist you significantly in obtaining significant body transformations. Supplements, in conjunction with an appropriate and consistent exercise and dietary regime have the potential to completely transform your body, no doubt about it. What you must avoid however is developing unrealistic expectations when you do see a supplement advertisement, as this may very well be setting you up for failure.

AST Sports Science Max-OT Program Review

posted by admin in Exercise

Many years ago AST Sports Science, a large international supplement company, released an online training programme entitled “Max-OT”. Interestingly, it was Max-OT that initially got me excited about bodybuilding.

During my 2005 BodyBlitz competition, I often trained in a similar manner to the Max-OT program for both cardiovascular and resistance training. Though this was certainly a highly effective approach to training, within this review let’s touch on various key area’s of the programme as to determine the suitability in assisting you toward your bodybuilding goals.

What is the Max-OT Training Program?

In a nutshell, it is a high intensity bodybuilding programme.

The weights programme relies on a low repetition range of 4-6 to failure. It also relies heavily on large compound movements (that utilise multiple joints).

The cardiovascular aspect to the training programme is also high intensity. It is based on interval training and is a gruelling approach to losing fat.

The nutritional recommendations are heavily reliant on AST Sports Science supplements – particularly the world-famous AST VP2 (that we sell in our supplement store).

Does the Max-OT Program Work?

Probably the most common question is whether or not the training programme works. It shies away from the more typical text-book 8-12 reps for hypertrophy and goes right down to some very heavy loads at 4-6 reps. Though fitness text books generally recommend this for strength training as this targets the type IIbx muscle fibres, AST Sports Science argues that the type IIbx muscle fibres have the greatest potential for volume growth.

While individuals may respond differently to varying training programmes, I personally did experience some good hypertrophy results at such a low repetition range. After all, practically all my training prior to and during the BodyBlitz challenge consisted of 4-6 or less reps to failure.

The cardiovascular training is based on interval training. High intensity interval training is an extremely effective format of exercise to maximise oxygen uptake efficiency and fat oxidation following the conclusion of your workout. High intensity interval training can also have various carry-over effects to hypertrophy, many of which were noted in an article that I wrote for Australian Ironman, Cardio & Bodybuilding – Good for Muscle Growth?

Would Max-OT be Suitable for Beginners?

When I first began the training (back in 2003), the website did state that Max-OT was suitable for people of all experience levels. Though from both my personal and professional experience in the industry, I disagree with this completely.

For intermediate to advanced trainers, yes, a 4-6 rep range can be a highly effective form of training as part of a periodised training plan. I do however believe that there is a significant safety issue with beginners who attempt to lift such heavy weights at 4-6 reps to failure. Lifting these loads with underdeveloped proprioception, coordination, balance and stability can easily result in quite serious injury. I personally experienced this on numerous occasions when I was starting out, with (fortunately) minor injuries to my lumbar spine (on multiple occasions), calf and shoulder (on multiple occasions). With poor exercise execution and ineffective control of the weights being lifted, such a high-risk training programme should be avoided.

General Observations about the Max-OT Training Program

The Max-OT program was obviously created as a marketing strategy to promote the AST Sports Science supplementation range – it doesn’t take a marketing guru to figure that one out. Throughout the programme you will read numerous references to the superiority of the AST Sports Science supplement range. Personally I do believe that the AST range is a very high quality brand – but they can tend to overdo the sales pitch on the website every now and then.

The nutritional programme that was developed for Max-OT was in my opinion extremely unhealthy being heavily reliant on AST Sports Science supplements. There were regular servings of supplements throughout the day; of seven meals, only one does not contain any protein based supplements. I believe that the protein intake is excessively high, especially for someone who is new to bodybuilding.

Overall, the programme is quite a good one that I have enjoyed personally. It is a marketing campaign – and an extremely successful one at that. If you are a beginner, I would recommend to stay well away from it until you develop a foundation from which to build upon. Having said that, the AST VP2 is an excellent quality protein powder which can aid you toward your health and fitness goals.

High Intensity Exercise – Do You Need To Train Hard For Weight Loss?

posted by admin in Exercise

If you’ve seen The Biggest Loser, you’ll observe overweight individuals slogging it out in order to shed phenomenal amounts of body weight. There is no doubt that they experience weight loss results, often in the order of multiple kilograms per week. Though this approach is generally considered to be an unhealthy and unrealistic approach to weight loss amongst many fitness professionals, such a television show does imply that high intensity exercise is a necessary practice to lose significant amounts of weight. This assumption is simply incorrect.

If you’ve been following our articles over the past few years, you’ll be well aware of our stance on the intensity of your workout. In a general sense, the higher the intensity of your workout, the greater the physical, mental and emotional benefits you will obtain. Pushing yourself outside of your comfort zone will result in greater personal development both on the outside and on in the inside, for it requires great inner strength, determination and focus to consistently undertake high intensity workouts.

However if you fall within the wider general population who do not enjoy testing their physical and mental limits through high intensity exercise, a demanding exercise regime can pose a significant hindrance to obtaining long-term sustainable results. Personally, I have seen this happen a number of times in the past through my professional experience in the industry. A classic example is where a client has been pushed too far outside of their comfort zone resulting in them feeling nauseous or even vomiting. Such an experience puts somewhat of dampener on the whole “exercise experience”. So rather than exercise being associated with the great feelings of endorphin release and self-achievement, it is instead regarded as uncomfortable and nauseating.

Ask any person who has achieved an amazing health/fitness feat what a key ingredient to their success was. One important factor is likely to be consistency – for anything that is worth accomplishing requires a continual and dedicated approach toward the ultimate goal. This would be true for anyone whether they have lost a large amount of weight, competed in a bodybuilding competition, won a transformation competition, competed as an athlete at an elite level and so on. A repeated approach toward a particular goal over the long-term will almost ensure success (with the right approach of course).

Therefore, if you are someone who loathes high intensity exercise, a lower intensity approach may be suitable if this will enhance your likelihood to exercise on an on-going basis. It is far more beneficial for your health to exercise at a low to moderate intensity for a few times a week than to engage in exercise at a high intensity sporadically. Though the results may be greater from a high intensity session relative to a low intensity session, the long-term results will only be greater if you are consistent in adhering to an appropriate routine.

To lose weight, you require an energy deficit by consuming less calories than what is expended. While this can be accomplished through diet alone, it is of much greater benefit to incorporate an exercise routine to accompany an appropriate approach to nutrition. This will aid in boosting your immune system, avoiding muscle atrophy (or breakdown), improving self-confidence and self-esteem, enhancing your cardiovascular fitness, improving brain function and so on. Of course, since energy is expended during exercise, undertaking a workout will also facilitate weight loss by encouraging an energy deficit.

The take home point – no, high intensity exercise is not a requirement for weight loss. So if you do not particularly enjoy working out, try something that you feel more comfortable with in order to develop a routine. Some movement is better than none at all and this will form a foundational routine from which you can build upon in the future.
