IT’S MORE THAN JUST ENERGY IN ENERGY OUT!Here’s the deal; getting shredded is as simple as “energy out” exceeding “energy in.” However, there are so many variables that define energy in and energy out that it may be difficult to calculate. There are three commonly used approaches when pursuing fat loss. The wrong way, the right way and the best way. Unfortunately, a lot of people with honest intentions fall into the first category – eating sensibly and working out regularly but still without results. This can occur by a number of factors:
Herein we will present a comprehensive overview of how to do things the right way. But more importantly, how to do things the best way, ensuring the correct approaches are combined and personalized for optimal results.
LET’S START BY TALKING ABOUT ENERGY IN AND ENERGY OUT.
Believe it or not, tracking calories is an important consideration when calculating your energy in versus energy out. Start getting used to this approach to guarantee long-term success.
Find a calculator online that will consider your age, weight, height and activity level to predict the amount of calories per day required to maintain your current body weight. These are heavily studied equations and some can be so good that they match the values reported by physically measuring your basal metabolic rate (BMR) (1). Once you have obtained your calories, knock 20% off of this number. Some diets prescribe extreme and potentially unhealthy daily caloric restrictions between 800 and 1500 calories per day, regardless of who you are (2). Reducing your daily maintenance calories by 20% is subtle enough to produce weight-loss results without an extreme energy deficit and the associated hunger pangs.
… PROPER CONDITIONING WILL ENSURE YOU STAY IN A WEIGHT-LOSS ZONE AND BETTER YET, SPECIFICALLY TARGET FAT STORES.
Have you ever heard the expression, “sweat is just fat melting away.” Although maybe not scientifically accurate, the idea is there. Sweating is a sign that your heart-rate is up, you’re breathing heavy and you’re burning calories.
If you’re doing cardio for extended periods of time, you will certainly lose weight by burning enough calories to maintain an energy deficit. For optimal results; however, recent scientific evidence points towards particular modes of exercise that will specifically enhance fat loss.
It is commonly understood that to target fat loss, an individual should train somewhere around 60-65% VO2max versus higher intensities floating around 85% VO2max. This idea was birthed from evidence that greater proportions of calories are derived from fat while training at lower intensities (3). However, new evidence has shifted this mindset towards high intensity interval training (HIIT) and high intensity interval resistance training (HIRT). For instance, a HIIT routine of cycling for 20 minutes including 60 seconds at high intensity separated by 60 seconds of active recovery had the same effect on 24h energy expenditure (24h EE) as steady endurance training (END) at moderate intensity for 50 minutes (4). The daily energy expenditure of individuals partaking in 20 minutes of HIIT or 50 minutes of endurance training was 3766 and 3526 calories per day, respectively (4). Thus, the former routine provides a far more efficient method of enhancing daily energy expenditure. If you were to perform the HIIT routine for the same amount of time as END, the presumed outcome is a substantial increase in daily energy expenditure beyond what was seen with END; thus, resulting in accelerated weight-loss.
You may be wondering – although HIIT provided the same 24h EE as endurance training in less time, maybe it was still less efficient at targeting fat stores considering training occurred at higher intensities. If this is what you were thinking, than I commend you, that’s a fantastic thought! However, recent studies have shown that HIIT 3 times per week for 20 minutes including 60 sets of 8s sprinting and 12s active recovery, was superior to steady-state exercise for 40 minutes at 60% Vo2 peak in producing total fat loss after 15 weeks of exercise (5). So good thought, but you just got HIIT with some new knowledge on how to best burn fat (*wink)! The exact mechanisms underlying changes in body composition between steady state cardio and HIIT are unclear. However, a study recently published in 2014 provides some clues for the effect of HIIT on 24H EE. Compared to moderate intensity exercise, athletes who partook in HIIT cardio displayed a significant increase in plasma levels of citric acid cycle (TCA) intermediates (citric acid, aconitic acid and succinic acid) immediately after exercise (6).
The TCA cycle is the final common site of all aerobic processes in human tissue. This includes the metabolism of carbohydrates, protein and lipids for energy, generating about 67% of whole-body energy (7). Thus, increasing TCA activity translates into massive surges of metabolic activity. This is undoubtedly the main driver of 24H EE following HIIT compared to steady cardio.
RETENTION OF LEAN BODY MASS WHILE IN AN ENERGY DEFICIT IS THE KEY TO REVEALING TONED MUSCLES ONCE LAYERS OF EXCESS FAT COME OFF.
Similarly, growth hormone was shown to increase immediately following exercise and at 1h of recovery post-HIIT versus moderate intensity exercise (6). Retention of lean body mass while in an energy deficit is the key to revealing toned muscles once layers of excess fat come off. Growth hormone has been shown to elicit this effect by preserving lean mass and significantly enhancing nitrogen retention during weight loss (8). Additionally, enhanced release of free fatty acids (FFA) from fat tissue and uptake into muscle cells has been demonstrated in response to growth hormone in human studies (9).
Finally, the amino acid, alanine was shown to increase immediately and 1h post-HIIT compared to moderate intensity exercise (6). Studies have shown that administration of alanine in combination with other amino acids significantly enhances serum free fatty acid levels following exercise (10), making them available for uptake into metabolically active tissue. Therefore the key to a successful cardio routine as part of overall conditioning for a shredded physique is to include HIIT cardio. By this method, your body becomes more metabolically active in ways that stimulate the fat burning process. With this conditioning, you’ll burn more fat in half the time, the numbers simply don’t lie!
YOU’LL BURN MORE FAT IN HALF THE TIME, THE NUMBERS SIMPLY DON’T LIE!
When it comes to training for fat loss and abs, cardio always dominates the conversation. You have to lose the fat stores to reveal the abs. This is absolutely true, but a strong resistance training regime always compliments a masterful cardio session. We’ll discuss briefly how to maximize the energy expenditure during resistance training with high intensity interval resistance training. Conditioning for fat loss and revealing elusive abs is all about energy out exceeding energy in. Therefore, to reach your goals the quickest, obtaining maximum fat loss and energy expenditure should be at the heart of physical exertions. In this regard, all resistance training regimes are not created equal.
Take for instance a recent peer reviewed publication that proves HIRT (High Intensity Resistance Training) training is superior to conventional resistance training for optimal fat oxidation (fat burning) and energy utilization (11). Seventeen resistance trained men took part in a HIRT regime that consisted of 22 minutes of training legs, chest and back. The first set was done to 6 rep max (RM) followed by two additional sets, each until failure. Sets were separated by 20 second breaks and exercises were separated by 2 minutes and 30 seconds. One week later, participants conducted traditional training routines (TT) consisting of 52 minutes of 4 sets of 8-12 reps between 70-75% 1RM with 1-2 minutes rest between sets. This routine included bench press, military press, biceps curls, triceps extensions, leg press, leg curls, sit ups and dorsal machine. The resting energy expenditure (REE) of the TT group increased from 1901 calories per day during the recovery period to 1999 calories per day at 22 hours post-exercise. Interestingly, in the HIRT group, REE increased from 1910 to 2362 calories per day at the same time points (11).
COMBINE HIIT WITH THE SECRET INGREDIENT – HIRT, AND YOU’LL BE SHREDDED IN NO TIME!
This is an incredible 363 calorie difference just by switching the mode of resistance training! With that said, in the same study, HIRT was shown to specifically engage fat as a fuel source compared to traditional training at 22 hours post-exercise (11).
Push your output with less time in the gym. Implementing HIRT in your daily conditioning will accelerate weight loss and help shred those last few pounds by enhancing energy expenditure and specifically targeting fat stores. To ensure a recipe for success, combine HIIT with the secret ingredient – HIRT, and you’ll be shredded in no time!
