Lasagna nights count. Takeaway nights count. Wine counts.
Stakes are between you. We just keep score.
Three independent studies say the same thing: when someone's watching, you show up.
76% vs 35%
A Dominican University study found that writing your goal and reporting to a friend more than doubles the chance you actually hit it.

Harvard and UC San Diego tracked 12,067 people over 32 years. Habits, good and bad, travel between friends. Pick yours carefully.
Christakis & Fowler, NEJM, 2007

Most guys prep for a natural bodybuilding comp eating chicken and rice for 16 weeks. Alone. They cry in their kitchens at 9pm.
I didn't. I trained with a partner.
We didn't compete on weight loss. We competed on whose plan hit the macros. I ate burgers. I ate lasagna. I ate a Bacon and Egg McMuffin two hours before stage day.
I came second in the country.
He came fourth.
That's what this is. Beat your buddy. Eat real food. Both come out lighter.

Beat-a-Buddy
Pick your buddy
Plan adherence is the default. Want to add steps, water, weekly check-ins? Tick them on. Same for both of you.
Beat-a-Buddy
Pick the rules
The leaderboard updates daily. You both see who's ahead. No streak shame when you skip a day. Just whoever hit more.
Beat-a-Buddy
Tick what you ate
We don't hold the stakes. You do. Loser does dishes. Loser cooks Sunday roast. Loser TikToks in your accent. Pick what stings the right amount.
Beat-a-Buddy
Settle the stakes
We've watched mates settle bets a thousand ways. These are the ones that actually changed behaviour.
"$50 to the winner. Cash. None of this PayPal nonsense."
"Loser cooks Sunday roast for the family until Christmas."
"Loser does 100 burpees in the front yard. On camera. Posted."
"Loser TikToks in the winner's accent. Tagged @flexidiet."
"Loser empties the dishwasher every day for a month."
"Loser changes their LinkedIn headline to 'I lost a bet to [winner]'."
You don't win by eating less.
You win by sticking to the plan you and your buddy picked.
The plan still has lasagna.
The plan still has takeaway nights.
The plan still has wine.
The leaderboard counts ticks, not calories restricted.
This challenge is closed to anyone with a current or past eating disorder. We mean that.
Under 18? You can't enter. Pregnant, postnatal, or on a medical diet? Talk to your GP before changing anything you eat.
"Two mums. One week. Whoever cooked from the plan more times wins."
"Your husband's never lost a competition in his life. Until now."
"The diet that survives Wednesday is the one someone else is watching."
"Pick the friend who keeps saying 'I'll start Monday.'"
"Quitting at 9pm is easier when no one notices."
"Show up for someone else. Show up for yourself by accident."
Nearly 100 more challenges are waiting.
Beat-a-Buddy is one of nearly 100 ready-made challenges in FlexiDiet: solo, buddy, group, and coach-led.
Snack Golf, where every off-plan snack is a stroke and lowest score wins. Couch to 5K with your crew. Sugar Free 21. A dry month with your mates. Push-up throwdowns, step showdowns, sleep squads.
Same mechanic every time: pick a challenge, pick your people, check in, and let the leaderboard do the nagging.
You keep going. Your score is your own plan adherence, so nothing resets. If they go quiet for 3 days the app chases them with a reminder. If they stay gone, you finish the 14 days and the win goes on your record.
14 days. One buddy. No clean eating. No off-limits foods.
