Why Exercising for Weight Loss in Your 'Fat Burning Zone' is a Waste of Time
Have you ever ever heard a personal trainer or fitness skilled say that to maximise fat loss you need to maximise exercise time in your "Fat Burning Zone"? Conjointly have you ever noticed that just about any piece of cardiovascular exercise equipment incorporates a "fat burn" program spaced between the interval and random programs? What is the thus-called Fat Burning Zone anyway and why should you rummage around for better choices to assist you maximize your fat loss results? This article provides some basic information on the fat burning zone and why interval-sort training would possibly be provide permanent results faster.
The fat burning zone outlined
The Fat Burning Zone (FBZ) is an intensity (e.g. walking speed) of aerobic -type exercise that concentrates the employment of fat as a fuel. Exercise intensity is typically measured by monitoring your heart rate, thus exercising at about sixty five% of your heart rate max/HR max (220 - your age) places you in the "zone".
Energy/metabolic contributions whereas exercising
Exercise intensity determines the relative contribution of different energy sources (carbohydrate, protein, fat) to fuel it. For example, high intensity exercise like running and sprinting rely a lot of heavily on the utilization of carbohydrates than lower intensity exercise like walking in the zone that depends additional on the employment of fat.
Energy metabolism works on an exercise intensity continuum - that is at any intensity never does your body build use of a single type of fuel. As an example, even in an all-out sprint a number of your energy yield will come from fat and protein, however the big majority can return from carbohydrates. Equally, even in the fat burning zone a proportion of your energy can return from carbohydrates and protein, however a a lot of larger contribution will come from fat.
The basic rule is the higher the exercise intensity, the upper the relative contribution of carbohydrates to total energy expenditure and vice versa for fat - therefore it is in fact true that at the FBZ intensity, fat can be the maximal contributor of calories burned during the exercise session. (If I have confused you browse on for an clarification).
For the casual exerciser, the FBZ is actually useless
Here's why:
Fat and weight loss is directly enthusiastic about caloric (energy) balance - in different words if your total calories (food calories - exercise calories burned) in an exceedingly day are less than the number required to maintain your current weight, you will lose weight; if you consume more energy that what you need to maintain your current weight, you will gain weight.
Your body doesn't care where the "exercise calories burned" come back from - whether or not from carbohydrate, protein or fat, the key is the amount of calories expended. Exercising at the intensity the FBZ requires can take abundant longer to burn calories as a result of the ability output/energy requirement is so low.
EXCEPTIONS: Exercising in the zone may be helpful but for severely deconditioned or obese people who do not have the physical capacities to perform the next intensity-type exercise routine. If this can be the case, the fat burning zone should be viewed as a step toward progression.
The secret's to MAXIMIZE the amount of calories expended
Unless you have got several weeks and loads of patience to lose weight by consistently exercising within the FBZ; the best option is to maximize the quantity of calories burned in the shortest time frame. Interval based mostly coaching is a lot of higher suited to fast and safe weight loss.
Essentially interval training involves "bouts" of high intensity exercise separated by lower intensity "recovery" periods. An example of an interval would possibly be running at high intensity (80 - 90% HR max) for two minutes and then walking (60-sixty five% HR max) for regarding 4 minutes - keeping the work (run) to recovery ratio about one:a pair of or 1:3.
The walking sessions serve two purposes: they contribute to total calories burned and permit for recovery and energy regeneration for the next successive running bout. This kind of intermittent intensity training permits for a much larger burning of calories in an exceedingly a lot of shorter timeframe speeding up weight and fat loss.
So whether or not I burn carbohydrates with higher intensity interval-sort exercise I can still lose fat mass?
YES.
Keep in mind the supply of the calories does not matter. The carbohydrate stores in your liver and muscles (known as glycogen) depleted from exercise should get replaced during recovery. So basically more calories from food consumed once exercise will be directed toward glycogen restocking and fewer can be directed toward fat storage (it is only when the glycogen reserves have been restocked that the "excess" calories are directed to fat storage anyway).
Higher intensity exercise offers alternative benefits too
Analysis conjointly shows that higher intensity exercise will increase your post-exercise oxygen consumption (EPOC) and your post-prandial (once a meal) oxygen consumption. In other words, during recovery your metabolism is sort of significantly increased for several minutes to hours after stopping exercise. This boosts your caloric expenditure even a lot of over lower intensity FBZ-type exercise.
High intensity exercise can facilitate your lose fat while sparing valuable muscle tissue and additionally promotes faster will increase in your fitness levels since all your muscle fiber varieties (kind I, type IIA, IIB) are stimulated within the process.
In conclusion then, this text has pointed to the importance of exercise intensity on the burning of calories. Clearly if your goal is to lose weight and fat mass faster and become fitter, interval based coaching is by far superior to exercising within the fat burning zone.
