Hello I'm Stella Metsovas. And today we're going to talk about something I use to hear quite often in the gym. And that is what are the best fat burning stacks? So what is a stack? A stack is a combination of a few supplements that works synergistically to increase thermogenesis by boosting your metabolism. First of all let me dispel the myth of destroying fat cells. Genetically we're all gifted with a specific amount of fat cells that are influenced by the lifestyle and foods you eat. The notion of flushing out or getting rid of fat cells is biochemically impossible unless you literally suck the cells out by liposuction. Even then you have a genetic predisposition to expand in other cellular areas if your diet and lifestyle are still unchanged. Now if you prefer to enhance the metabolism after you've changed your dietary and lifestyle patterns I recommend purchasing ingredients rather then a long list of ingredients found in leading fat stacking supplements that can possibly do more harm then good. Decreasing the size volume of your fat cells can be obtained by taking in a form of caffeine either through coffee or tea that biochemically releases more energy from fat. Typical means of caffeine stacking actually come in the form of supplementing approximately 200 milligrams of caffeine between meals two to three times per day. Be very careful here because you don't want to impact your adrenal glands by increasing cortisol levels. And that's why I recommend drinking coffee or tea at two cups maximum per day. Natural calorie burners like green tea extract, raspberry ketones and cayenne pepper have also been studied for their thermogenic properties. You can also burn fat for energy instead of carbohydrates from your dietary habits by using intermittent fasting or ketosis as a strategy. Again careful here, you don't want to upset your adrenal glands or your thyroid. Transporting fat through the use of carnitine, an amino acid is one of my personal top picks. Actually it's my favorite pick. Take 500 milligrams, one gram before a workout.
