Can Consuming Caffeine On A Low-Carb Diet Kick You Out Of Ketosis?

Filed under: Low-carb Tips — @ August 25, 2007

In an ideal world, there would be clear-cut criteria laid out in black and white about how to do a low-carb diet. While there are certain basics that apply to virtually every low-carb plan, there are also what I would describe as “gray areas” where it will really depend on the individual to figure out for themselves.

One such issue is caffeine. If you have read Dr. Atkins’ New Diet Revolution, then you know the late great Dr. Robert C. Atkins addresses this subject a couple of times–but only in passing. Here are the two brief references I found in my mass paperback version of the book:

Page 189–“Excessive caffeine has been shown to cause a hypoglycemic reaction, which will provoke cravings and cause you to overeat. Omitting caffeine may be a big sacrifice for you, but, in my experience, weight loss often starts up again as soon as people remove caffeine from their regimen.”

Page 222–“Consume caffeine only in moderation.”

Other than those two points, Dr. Atkins didn’t say much else about caffeine consumption. Obviously he felt there was enough of a negative metabolic response to caffeine intake for him to dissuade Atkins dieters to try to steer clear of it as much as possible.

But what about the impact of caffeine on ketosis? Is there any and what guidelines can people following a low-carb diet use to gauge what amount of caffeine intake they can tolerate while still losing weight?
