I downloaded MyFitnessPal from the App Store and started logging what I ate, to try and gently shame myself into eating better. If you're trying to improve your fitness and not following an existing diet plan (such as the one that comes with T25) then it makes a lot of sense to use something like this app to help visualise your calorific budget. It tallies up your calories based on the food and exercise you input, breaks down where those calories have come from - carbs, fat or protein - and how that compares to the suggested ratio. It does depend on how far down the fitness rabbit-hole you want to delve, but after a week of what felt like hard work, I made the decision that it was something I'd like to do.
Another app I started using this week made me feel more shame than seeing an empty net of babybel in the fridge - "Daily Water" visualises how much water you've drank that day with a handy red Alert icon on and lets you set reminders to DRINK WATER NOW; just in case you're so busy enjoying white privilege that you forget to drink anything besides bubble tea, flat whites, and £2.50 cans of pop from American import shops. If any app developers are reading then get in touch, I've got an idea for an app which prompts people to inhale and exhale at regular intervals - we'll make a fortune off assholes like me.
