Name your acne triggers

I thought it might be a good idea to have our members list known acne triggers so we can use the search function for 'trigger'

I'll start

more than one serving of dairy a day
too much red meat
too much sugar
tropical fruit
too many whole grains or legumes

Clogged pores on chin/jawline?

Sooo about 2 months ago I cleaned up my diet and cut out almost all processed foods. Since then, my diet has been mostly eggs, meat, vegetables, fruit, potatoes, dark chocolate and limited dairy products. I actively avoid high GI foods like sugars and starches. My skin has slowly purged lots of clogged pores and I'm finding the last couple clogged pores are clearing and they are on the sides of my chin. I'm wondering if anyone has had a similar experience, or has pinpointed the cause of clogged pores around the jawline. This is the most stubborn and hard-to-get-rid-of form of acne for me, and any advice or anecdotal evidence would be appreciated.

I also think physical activity daily and especially after meals is really important in getting clear.

Drinking Water

Has anyone had success with upping their water intake for clearer skin?

The Cost of Accutane

Caloric Restriction

Has anyone tried just plain ol CR without avoiding any specific foods and noticed their acne clearing up?
