Firstly, do not eat a large meal just before sleep. This will trigger your digestion system and will affect your sleep.

Also, I'm surprised that you find exercising before bed beneficial. That contradicts everything I've ever heard. But compared to everything else you describe, changing this ...

One calorie (with a lower case c) is the amount of energy required to heat 1 gram of water by 1°C. A kilocalorie is 1000 calories, and Calorie (with a capital C) and kilocalorie are synonyms. On food labels, nutrition facts are in terms of kilocalories/Calories. (Wikipedia)
Just like with grams vs. kilograms, units are used in a way that the number most ...

Energy metabolism is not a very well understood system in the sense that while the biochemical reactions are well known, their dynamics is highly variable depending on the individual. I find it disturbing that so many people have their own understanding of how their body work, without any sound reasoning behind it. Below I'll try to give some background ...

There are many factors that contribute lack of energy, but nutrition-wise, one of the reasons is "fast" carbohydrates (especially sugar). Carbonated soft drinks are usually the worst offenders.
After you consume sugar, it immediately ends up in your blood, so your blood sugar level rises rapidly. Your body counters it by producing more insulin to maintain ...

Try taking some melatonin before bed. Melatonin tends to be hit-or-miss in my experience, people I know who have tried it have had either great results or none at all. You can pick it up in any drug store, so it's worth a shot.
You mentioned being tired during the day, does this happen even when you are getting enough sleep? You could have sleep apnea, a ...

If you really can't get away from screens, take a look at f.lux, which changes the brightness and colors of your screen according to the time of day where you are. It won't fix the problem of screen-time near bed-time, but I've found that it mitigates it. It can be switched off quickly and easily if you have color-sensitive work to do.

Sounds like you have two goals.
Fall asleep faster
Fall asleep earlier
First, I'd suggest you learn about your own sleep patterns. Lifehacker had a nice article on technology that can be helpful. By keeping closer track of the experiments you've done that are mentioned above you might notice things like, you need two days of consistency to make staying ...

One way of looking at aerobic function is as the bodies ability to burn fat for fuel at a given pace or speed. Anaerobic function then is the bodies ability to burn sugar for fuel when we move beyond the pace at which we can burn primarily fat. Heart rate is often a good indicator of which mode we're in.
Intervals and speed training, then, burn mostly sugar ...

Your question doesn't sound like you are overweight and need to watch your calories.
In my opinion you could replace the brownie with some whole grain energy bar, replace the simple sugars with some more complex carbohydrates and maybe have some additional fibers, too.
But the question is if you should.
I think this is more a mental thing, the boost ...

These have often been helpful to me in this area:
Exercise
Proper vitamins such as B and Magnesium
Reduce or eliminate alcohol intake as this can act as an inhibitor
Proper eating (smaller meals more frequently)
Include short bursts of intense activity with lower intensity activity in your workouts several times a week
Ensure you are not depriving your ...

In an effort to support the very thorough answer given by @Berin Loritsch, here is a more explicit conceptual picture.
The mass food that is taken into the body (A) has 3 potential fates:
1) it will not be digested or absorbed by the digestive system (gut) and will pass out of the body via the anus. There are many factors that affect this but mainly it is ...

To answer that question it would require a long discussion about the pancreas, the colon, the kidneys, the liver and general digestion. I believe the thyroid also has a role to play.
The one organ that is most involved with regulating the fat stores is the pancreas. When your body has a surplus of blood sugar, it secretes insulin which stores the excess ...

Here's a related question: How to get rid of oversleeping?
Although your situation sounds worse. If you're taking a nap during the day you should stop. Are you exercising at all? If not, try going for a run after work or lifting weights at the local gym. Exercising will help you in many ways: it will make you physically tired, it will get your mind off of ...

Should you switch to something less enjoyable but healthier? That depends on how much you enjoy it, and how integral to your habits this has become. If you find yourself "going to the gym so you can eat a brownie", then the brownie has probably become integral to your exercise as a reward for your workout habit. Exercising regularly is better for you than ...

Actually, Sustained Energy and Perpetuem from Hammer Nutrition can be concentrated into a paste. With this, you don't really need to drink a ton of water. But, if you are running for a few hours, you'll definitely want to consume 20-24 oz of water in addition to your fuel.
Another great company is Infinit Nutrition. They have some very good products ...

Your premise is a bit off. Protein and Carbohydrates have essentially the same number of Calories. It's fat that has more calories.
Protein: 4 Cal/g
Carbohydrates: 4 Cal/g
Fat: 9 Cal/g
In order to understand how Atkins and other ketogenic diets work, you need to understand a bit about energy systems and a very important pair of hormones. ...

Maybe your calorie reduction is too drastic to support increased activity. Try figuring out how many calories you are consuming, and comparing that number to the calories you need to maintain your weight (you can find tools online to help with this). To lose a pound a week, you would need a deficit of 500 calories a day. If your calorie deficit is too large, ...

Here is one more possibility to throw out there: you may be dealing with sleep apnea. Sleep apnea doesn't have anything to do with your physical activity or your diet. Both my friend and I deal with the ailment, and long before I started getting active he has always been active and healthy. Yet we both deal with it.
What is sleep apnea?

You should be to try and get your circadian rythm back on track. This is not a quick fix, it requires patience and effort, but should be your best bet.
The first order of business is basic sleep hygiene.
Try to go to sleep at the same time every day.
Avoid anything that interferes with your sleep, such as
caffeine late in the day
eating close to bed, or ...

Sleeping the same amount every night is important, but it's just as important to go to sleep at the same time and wake up at the same time every night. For example, if you sleep 10pm-5am one night, then midnight-7am the next, and 3-10am on weekends, you'll probably still feel tired even though you're getting about 7 hours of sleep every night. Our bodies ...

It is still confusing, because both terms (with and without the kilo- prefix) covers the same amount, and it is only a capital letter that differentiates beween 1 and 1000.
This would be equal to having Gram (with a capital letter) and kilogram being the same, and gram being 1/1000 of that. I hopy everyone can see how stupid that would be, and this is ...

I will do my best to address this question in a practical manner. Namely, I think the best way to burn fat and spare muscle while training is to construct a hypocaloric diet and workout plan with muscle preservation in mind.
Steps I would take:
Ensure diet is hypocaloric so that you actually lose weight over time.
Continue weight training while dieting. ...

It means the equation isn't perfect, but just an estimation. You happen to have found one case where it fails quite a bit. Of course, it doesn't help that you didn't describe an actual human being (the shortest verified person is 54.6cm, that is 21.5 inches). I don't feel like doing the path, but I'm sure the formula provide reasonable estimations for ...

It goes without saying (?) that these rep ranges are to some kind of failure. The idea is that failure occurs because some system is depleted/damaged and with rest it will be repaired and eventually strengthened. 1-3 reps is thought to stress out your neurotransmitters so you fail and the body's response is improved nerves and muscle recruitment that ...

Technically speaking, the energy used by the muscles is not glycogen, but the phosphate bonds in adenosine triphosphate (ATP). When energy is needed, one of the phosphate bonds is broken, resulting in an energy release and the creation of the subsequent adenosine diphosphate (ADP) and waste materials. This is one of the main reasons that creatine phosphate ...

Eating carbohydrates (sugars and complex carbs, not fibers) will prevent you from getting light-headed, weak, or tired during exercise. Often a single piece of candy or a cookie is enough to restore and maintain energy. Play around and determine the amount that works best for you, but don't take more than you need or you'll lose the weight-loss/maintenance ...

If you want to increase your overall time under load (which based on other posts of yours is a strong possibility), this would be a good time to increase the weight. That way, on your low energy days you'll already have built the base to keep the higher weights.
Why not go up by at least 5lb in all your lifts, and keep at least the same sets/reps you've ...

Snack on food with a low Glycemic index (most fruits and vegetables, legumes/pulses, whole grains, nuts, fructose) instead.
From Wikipedia:
A lower glycemic index suggests slower rates of digestion and
absorption of the foods' carbohydrates and may also indicate greater
extraction from the liver and periphery of the products of
carbohydrate ...

If you work seated during much of the day, make sure to get up and move around at least once per hour. Standing while on phone calls or webinars is a great way to fit that in. I've noticed that doing so really increases my energy and I feel much better at the end of the day.
I see the sugar factor has been mentioned. If it's difficult for you to go without ...

It sounds like you've reached the tipping point, and are possibly overtraining at times. Long training sessions will cause a rise in cortisol levels, putting your body into a catabolic state. This will make you feel tired and can even stunt muscle growth. Cortisol levels rise when the body is put under stress. Of course inconsistency plays a big part as ...
