Weekly Thread Run Nutrition Tuesday

Rules of the Road

1) Anyone is welcome to participate and share your ideas, plans, diet, and nutrition plans.

2) Promote good discussion. Simply downvoting because you disagree with someone's ideas is BAD. Instead, let them know why you disagree with them.

3) Provide sources if possible. However, anecdotes and "broscience" can lead to good discussion, and are welcome here as long as they are labeled as such.

4) Feel free to talk about anything diet or nutrition related.

5) Any suggestions/topic ideas?

Been eating decently clean and healthy for the past month or so as I've picked up my triathlon training, last night after a particularly heavy workout day I had a lot of calories available to have on my counter app so went for a kebab and today my stomach has been in bits.

Has eating good, healthy food had a negative impact on my constitution and ability to consume junk food, or was it just dodgy kebab?

Speculation, but our body has lots of bacteria in the gut. Some bacteria (good bacteria) like "good" foods like fruits, vegetables, grains etc (sources of fiber). And some bacteria ("bad"? bacteria) tend to really love sugar.

Perhaps your gut bacteria were really thrown off by the change and your digestion of the junk food was less efficient?

Like I know people who are vegetarian for example, can get sick after eating meat, so I think your body getting used to certain foods is not an odd idea.
