The ultimate fat burner (or body cutter) is the appropriate deficit diet, and optimized and complimented with appropriate training/excercise routine on a regular basis.
A deficit diet, in itself, without any scheduled excercise program can also make one lose weight. What does this tell us? That the DIET is absolutely the Boss and everything encircles the diet, and one will lose tissue, if they are healthy and have no organ issues or other medical conditions that would or could hamper progress.
This is what you need to do:
This an approxomation science, but you can narrow it down very close, if your meticulous in your vision when looking at the data.
Tweak your desire and passion by educating yourself on the basic requirements of losing fat tissue. With your age, sex, hgt, and wgt, in mind, find your approximated base calorie needs (this is organ function, breathing, or bodily function needs).
Armed with this knowledge, next figure in your approximated activity calorie expenditure (training/exercising, etc), and add this on top of the approximated base calorie need. This will give you the approximated maintenance level (or like a approximated break-even point in the caloric equation)
Apply this knowledge by backing off the approximated MT Line (approximated Maintenance line), say for example, a -500c per day, for about 1 week. Before the week begins, weigh yourself in the AM when you FIRST get up (do not eat yet) (remember your clothing, preferably with just underwear and t-shirt or like clothes). Note the time, and the approximated wgt.
Each day spread your caloric content out throughout the day (keep the body fed, with calories in the 300 to 500c approximated calories each meal), or a like division which mirrors your end caloric deficit limit (meaning MT-500c).
This way you have your entire day and body encircled with nutrition (I assume you alread know to eat clean), which if your eating right, will give an approximated good energy (not optimal because your in deficit) to fuel your training and exercising schedule.
At the end of the week, on the same day, the same time, with the same like clothes, weigh yourself again. Note whether you lost or gained tissue (or weight I mean). To further assist you, I want to tell you that for every approximated caloric deficit of (-3500c), one could lose 1lb of fat tissue. (though some may not all be fat tissue, this information is for another question, and isnt presently suited here).
Now, in this example you were calculating a -500c per day deficit. There needs to be -3500c to lose approximated 1lbs of fat. Now lets do some basic math. -500cX7=-3500c. With all things considered equal, and you were meticulous and faithful on the diet, you should have been CLOSE to losing at least one pound of tissue in the week.
If this didnt happen, this means you need to make finer adjustments, and the MT line is not accurate, and you need to adjust this on your own........based upon the FEEDBACK your body is giving you, AND ask yourself how faithful you were on the diet, AND how faithful in training (whether you kept the training schedule (if you didnt, this would effect the caloric equation, no?!), AND how acurate you figured in your activities caloric wise.........but, you have the base information to begin makeing adjustments.
One can not spot reduce. Losing fat is like draining a pool. The shallow end seems to drain before the larger deeper end. One can't choose where to lose fat; it will be lost all over the body.
The Nutrients are an essential factor in the diet; however, the law of energy balance within the DIET, is the ulitmate KING while the Nutrients can play in some decisions made within the body.
Do yourself a favor, figure out your MT line, adjust off of this, eat well balanced spaced out meals (DONT EVER starve YOURSELF), AND listen to your body for the results. While you are trying to figure out your body, IT WILL PAY YOU BACK, I promise. You have to learn to MASTER yourself to become the master of weight loss for YOURSELF.
What was your weight routine and diet like during your bulk? And, how long was this? What was your calorie consumption like? Was your weight routine progressive in nature? Besides lowering body fat, do you have any other goals?
