Caffeine – Effects • Boosting Your Metabolism • Giving You An Energy Boost • Increasing fat oxidation • Increasing energy expenditure • Enhancing exercise performance
Caffeine - commonly consumed as psychoactive substance in the world. • Fat-burning supplements • One of the few substances known to help mobilize fats from your fat tissues and increase metabolism. • Caffeine works by blocking an inhibitory neurotransmitter called adenosine
Can Caffeine Help You Lose Weight? • By Boosting Your Metabolism Ingesting caffeine jumpstarts the process of lipolysis • By Giving You An Energy Boost It increases alertness and wards off drowsiness temporarily https://www.ncbi.nlm.nih.gov/pubmed/7485480
Coffee - Mobilize Fat From Fat Tissue Stimulates the nervous system Increase in the levels of hormone epinephrine/ adrenaline Leads to break down of fats and release into blood Caffeine may stimulate thermogenesis Enhances Fat Oxidation leads to a rise in the levels of the hormone norepinephrine and the messenger molecule cyclic adenosine monophosphate (cAMP)
Coffee - Increase Your Metabolic Rate caffeine increased fat burning Caffeine can increase RMR by 3–11%, with larger doses having a greater effect
Caffeine and weight gain Consuming caffeine throughout the day - weight gain, because caffeine affects cravings for food Caffeine raises the stress hormone cortisol, which tells your body to increase its energy stores Caffeine also contributes to insulin resistance, when glucose and insulin build up in the blood.
How Caffeine Affects Your Workout ? Caffeine functions as a stimulant. Heart rate Blood flow “Studies using colas, energy drinks, or a sports drink with caffeine added, all show a positive effect on exercise performance. The most interesting thing is that some of these have provided quite low amounts of caffeine, as low as 1.5-2 mg/kg and there is still an effect.”
Caffeine can increase endurance, and make your workouts feel easier. Caffeine can increase endurance up to 30 % as well as improve your speed by 2-5 %. With caffeine, your body’s muscle consumption of glycogen (stored energy during exercise) decreases, which forces you to use fat reserves as energy and results in delayed muscle fatigue
Timing matters: before a long workout is best. Coffee and enhance performance when consumed 15-30 min before exercise. It may improve exercise performance by 11–12%, on average By blocking adenosine, caffeine increases the firing of neurons and release of neurotransmitters like dopamine and norepinephrine. This, in turn, makes you feel more energized and awake
Supports Peak Physical Performance • Caffeine could act as an ergogenic aid – a compound that improves physical performance. • Increase exercise enjoyment, decrease perceived exertion and fatigue, and also make you feel more focused and energetic
