I eat more cold sandiwches & salads, and garden produce in the summer. Many times I even go completely meatless simply because there's so much garden bounty to use up. I rarely turn on the oven unless I desperately have to. And I even will use the nucro-wave or crock-pot to avoid use of the stove-top when it's super-hot.
So far this season we've seen only MILD temps- normally by this date we've seen upper-90's and maybe even 100 by August, but today, can you believe it's a cloudy, cool 68 degrees? Unheard of!
*As a big guy- oddly, it's always been easy for me to quickly drop weight. In some commercial kitchens- particularly those in the early days that did not have A/C, I could literally lose 12 lbs. in ONE WEEK simply by eating well, drinking lots of wa-wa, and perspiring SO MUCH.
In the mid-west where summers are hot & sticky, there were days when it was 100 outside and I know for a fact that I must have worked right on the line at grills & flat-tops in confined spaces that HAD to be 120 degrees. I've changed uniforms 3-4 times during a single shift before- was so soaking-wet that one didn't dare go into the walk-in freezers. (Though on such days in such temps a trip into the walk-in COOLER was HEAVENLY! I remember having to work inside the walk-ins when decorating large cakes, scooping ice-cream for banquets, or piping dishes of mousse for large catered affairs...
