Our agency’s weekly “Speakeasy” meetings feature a lively exchange of content and ideas. This week we’ve been discussing (and sometimes scratching our heads over) a new crop of digital gadgets focused on keeping you fit and healthy.

• Smart belt loosens automatically when you overeat. Wait, shouldn’t it do the opposite?
• Vessyl magically recognizes any liquid you pour into it so you can track calories. Cool!
• Fork vibrates gently if you eat too fast. Better idea: max out the vibrations so your hand can’t find your mouth.
