Hidden Calories in Diet Coke / Caffeine bad for diet?

To answer your 2nd question...from atkins.com:
Caffeine Jitters
Because caffeine temporarily raises your blood pressure, it can make you feel jittery and on edge. Taken too close to bedtime, it can keep you from having a restful night's sleep and leave you groggy the next morning. Caffeine also makes your body produce extra adrenaline, which causes your cells to become less sensitive to insulin-which in turn makes your blood sugar climb. Recent research has shown that a quantity of caffeine equivalent to 5 or 6 cups of espresso can increase insulin resistance by as much as 15 percent.2 Caffeine's effect on blood sugar causes some people to feel weak and unable to concentrate. If you drink more than two cups of coffee each day, consider cutting back or switching to naturally decaffeinated coffee. You could also substitute black or green tea, which has far less caffeine (both come in decaf versions) but do have a lot of valuable antioxidants. Many soft drinks, such as colas and Mountain Dew, contain caffeine, as do beverages containing guarana. Cut back on the caffeine and you might be surprised at how much better you feel after a few days.
As you cut the caffeine, increase your intake of other liquids to the level of eight 8-ounce glasses, or 2 quarts, a day. Mild dehydration from not drinking enough is a common but often overlooked cause of fatigue. Any low carb or no-carb beverage-herbal tea, an artificially sweetened soft drink or simply plain water-is fine.

The Chocolate Connection
What?s the quickest food fix for a bad mood? Chocolate, of course. In fact, a study in 1999 suggests that chocolate is the single most craved food in America.3 The value of chocolate for lifting depression probably comes from more than just the hedonistic pleasure of its fat, sweetness, creamy texture and delicious aroma. A number of different chemicals naturally found in chocolate could help to raise your spirits. The most likely candidate is a substance called phenylethylamine, which is chemically related to amphetamine. Chocolate also contains theobromine and caffeine, which are both stimulants. Even more on the plus side, chocolate is a good source of antioxidants. In fact, one 2-ounce chocolate bar has the same amount of phenols as a 5-ounce glass of red wine. Chocolate may cheer you up and even be good for your health, but a typical chocolate bar is high in carbs. To enjoy an occasional low carb chocolate treat, try an Atkins Endulge.TM Chocolate Candy Bar.

'In a study published in the October issue of the Journal of the American College of Nutrition, researchers at the Center for Human Nutrition in Omaha, Neb., measured how different combinations of water, coffee and caffeinated sodas affected the hydration of 18 healthy adults who drank caffeinated beverages routinely.
"We found no significant differences at all," says nutritionist Ann Grandjean, the study's lead author. "The purpose of the study was to find out if caffeine is dehydrating in healthy people who are drinking normal amounts of it. It is not."
The same goes for tea, juice, milk and caffeinated sodas: One glass provides about the same amount of hydrating fluid as a glass of water. The only common drinks that produce a net loss of fluids are those containing alcohol - and usually it takes more than one of those to cause noticeable dehydration, doctors say.'

Partially accurate, but misleading (which would describe most of what's written in the popular press about diet and metabolism). Caffeine is a phosphodiesterase inhibitor that slows the breakdown of cyclic adenosine monophosphate (cAMP). That doesn't produce adrenaline, but it makes however much adrenaline you have go farther.
The reduction in insulin sensitivity is well-known and not necessarily a problem. Basically, your body is either geared up for releasing nutrients into the bloodstream or absorbing them from the bloodstream; it won't do both at the same time. You need to do the former if you're trying to lose fat, you need to do the latter if you're trying to build muscle or just keep your lean tissue in good running shape. Caffeine pushes your cells in the "release fat" direction, which means they won't be inclined to store nutrients. When the caffeine wears off, so does the increase in insulin resistance, and your body is back to storing nutrients again.
So, if you eat caffeine on an empty stomach and/or before exercise, you'll just be burning more fat, suppressing appetite, etc. The above effects are only a problem if you take a bunch of caffeine with food, because then you're taking in nutrients but inhibiting your cells' ability to absorb them.

And bacon. You can order bacon on that double Whopper with cheese and extra mayo.
Diet drinks are actually recommended by most doctors that hawk the Atkins diet..... although, most recommend the caffeine-free versions. (there are more than you think... most of the clear drinks like Sprite and 7up are caffeine free, and there's always caffeine-free Diet Coke and Diet Dr. Pepper). 🙂
I don't think you can metabolize Nutrasweet. There are a few unfortunate people who could metabolize Olestra (that fat substitute used in the Wow! chips), but it was rare.
