No. The caffeine content in a normal 330ml coke does promote thermogenesis through metabolic stimulation but the amount it does this is so small that it is negligible. Cold drinks do not cause you to expend significant amounts of energy heating them up either. If you want to know the amount of energy a drink will provide then just look at the caloric ...

Your caffeine consumption, practically speaking, probably does not affect your workouts positively or negatively. As @JohnP pointed out, caffeine studies are on greater amounts than a couple of cans of tea per day. According to the Sports Med. 2001;31(11):785-807, "ingestion of caffeine as coffee appears to be ineffective compared to doping with pure ...

There are a couple of things here that are worth looking at further. Firstly, obviously, you are very keen on working out. I am pleased to see that you are having a day off a week. However, if you have been working out day in, day out over a long period, it maybe that you need a few days off. Any decent training program will have hard easy weeks, and ...

Fadi Hanna AL-Kass, You said you've been training for 4 years straight. Have you been performing the same routine or mixing them up? Many times, people get bored after performing the same routines for a very long time. So, if you notice that you've been performing the same routine for a while, that could be the reason for your lackluster energy. Go online, ...

Energy Drinks Generally, electrolyte drinks are most helpful for workouts lasting longer than 1.5 hours depending on how much you sweat. The more you sweat, the more electrolytes (sodium/potassium) you flush out and the more likely you are to need replacements. According to this WebMD article: The American College of Sports Medicine says that during ...

If you are getting exhausted and fatigued after only 30 minutes, the problem isn't that you need an energy drink. The problem is that you are working out too hard. The fact that you are feeling tired later in the days would support that. The point of working out is to put training stress on your system. After you have done that, when you rest, you improve....

I'm going to stab in the dark and assume you are getting home-cooked-style meals (which usually have around a 20:40:40 protein, carb, fat macronutrient split). I don't need a calorie counter to tell you that you are cutting pretty hard with that diet, by restricting both fat and carb intake and trying to fill your calorie needs for the day through protein. ...

First of all, you need to have break days. You are working out all 7 days a week, and that way your body doesn't get enough rest to recover. It's not any specific recovery, but the recovery of your system to prepare for the next workout. I know some people who workout all 7 days a week and are doing fine, but in your case, it's not the same are you feel ...

Here are my thoughts (I do not cycle much myself so they should be taken with a grain of electrolytes). Salt only contains two out of the 6 of the electrolytes your body requires (sodium and chloride). You should therefore preferably buy an electrolyte replenisher from a pharmacy. As I understand the main problems with sugar are: You can get fat It can ...

With numbers: It takes 1J to heat a g of water by about 0.24K. Hence, heating 330ml of colored+sugared water from 7°C (fridge) to 37°C (body temperature): 330 * 30 / 0.24 = 41250 J = 9852 cal = 9.8 kcal Energy content from the sugar of your coke: 330ml * (10g/100ml) * 4kcal/g = 132 kcal So you can heat a lot of water with the energy content of a coke. ...

There are pre-workout supplements that are non-stimulant (Magnum's Opus comes to mind). Most pre-workout formulations rely on trying to stave off CNS fatigue (which is not a thoroughly understood topic). CNS fatigue is prevented (in varying degrees) by: carbohydrates amphetamines caffeine I'd be a little wary of "I drank a cup of coffee before some ...

I would pick one sugar or caffeine. It is much more likely that you will fail if you if try to quit both at the same time. To address the question of reducing the craving. Make a habit of drinking 1 cup of water first thing when you wake up in the morning (drink more water in general). Dehydration is a contributing factor to fatigue. Calorie ...

Being tired throughout a day is not normal even your workouts are intense. I had a very similar issue, I was feeling very tired after my workouts. Later on, I figured out that I have high blood pressure problem. Please go to a doctor and get checked your body up, especially your heart. Drinking energy drinks is not the real solution and may worsen the ...

If I were you I would use more fruits and vegetables instead, you can make fresh squeezed juices. I remember a pic a have posted a month ago on on my facebook wall about Ironmanner (Ironman Triatloner) who has done whole competition on 10 bananas.
