Coffee has been proven to offer many weight loss benefits because it contains high levels of caffeine, which is known for having fat mobilisation and metabolism boosting properties. This is why a multitude of commercial fat burning supplements have caffeine as one of the main ingredients. We’ve outlined how coffee can help you slim down in further detail below:
Coffee contains metabolism-boosting stimulants
Coffee contains high levels of caffeine which increases the release of metabolism boosting transmitters Dopamine and Norepinephrine. Other biologically active substances which stimulate the metabolism in coffee are Theobromine, Theophylline and Chlorogenic Acid. Chlorogenic Acid may also slow carbohydrate absorption.
Coffee can help with fat mobilisation
The caffeine found in coffee can help with fat mobilisation, as it directly stimulates the nervous system, causing it to send a signal to the fat cells directing these to break down fats. After the fats have been broken down, these are released into the blood. This makes the fats available for mobilisation as fatty acids in the blood.
Coffee increases our metabolic rate
Another reason why coffee can assist with weight loss is that it can increase our metabolic rate. Our Resting Metabolic Rate (RMR) is defined as the number of calories we burn while resting. When we increase our metabolic rate this enables us to be able to lose weight more easily, as well as eat more without gaining weight. Studies have proven that the caffeine in coffee can increase the metabolic rate as high as 29 percent in people who are leaner and 10 percent for those who are obese, depending on the dosage which is consumed (http://ajpendo.physiology.org/content/269/4/E671.short).
Coffee improves athletic performance
As the caffeine found in coffee breaks down fats and releases these into the blood as fatty acids, having this readily available fuel source also increases athletic performance. Studies have proven that exercise performance can increase by as much as 12 percent (https://www.ncbi.nlm.nih.gov/pubmed/15657469/). Increased exercise performance also results in a higher metabolic rate and increased fat burning potential.
Coffee may assist with appetite reduction
Coffee may also reduce your appetite if one study is to be believed. The study uncovered that caffeine had an appetite-reducing effect on males, resulting in them eating less after consuming caffeine. Unfortunately, the same results didn’t occur with the females who were tested (http://www.sciencedirect.com/science/article/pii/S0271531788800770).
While the caffeine in coffee has been proven to speed up the metabolism and increase the body’s fat burning capabilities, over time the body can build up a tolerance to caffeine. To avoid this tolerance affecting its weight loss benefits, there are two ways this can be managed. The first of these is to gradually increase how much coffee you drink. For health reasons, this would only be a short-term solution. Another alternative is to cycle coffee intake to avoid building a tolerance. By cycling coffee intake, this could mean having two weeks on and two weeks off drinking coffee.
These are some of the many ways that coffee can help you to slim down. Another great reason to drink coffee is that it provides the highest source of antioxidants in a Western diet, even outranking fruits and vegetables. If you are wanting to use coffee for its many slimming benefits, it works much more effectively if you drink it black, without cream and sugar.
