Plan every meal and order delivery to hit a weight loss target

A Redditor let a Grok Bot pick every meal, order BOGO deals on Uber Eats or DoorDash and retune calorie targets from daily weigh-ins, and reports losing 20 lb in two months.

What they did

The poster, u/No_Yak8345, handed all meal decisions to a Grok Bot set up as a nutritionist. They do not cook, so the bot signs into their Uber Eats or DoorDash account in its own browser, hunts for buy-one-get-one deals that fit budget and macros, and builds the cart. At restaurants they send a photo of the menu and eat what the bot chooses. Every morning they type in their weight. The bot keeps one plain file with the weigh-ins, each meal as a low, likely and high calorie and protein range with a confidence tag, a list of regular meals, the current targets, and notes from check-ins every week or two. At each check-in it estimates actual daily burn from the 14-day weight trend against intake and proposes a new target for the poster to approve.

How it went

The poster reports losing 20 lb in two months while training, with most delivered meals coming to $10 to $12 after tax. They say the bot picks well about nine times in ten. Downsides they name: building a delivery order can take a long time when they are already hungry, and it sometimes picks food they dislike, which they fix by giving feedback rather than taking over. They still review the cart and press order themselves. Commenters only offered congratulations; nobody checked the numbers.

Worth knowing

Precise calorie counts matter less than a daily weigh-in, since the two-week trend corrects bad estimates. The poster avoided the delivery apps' own plugins because they did not show BOGO deals, and let the bot browse logged in instead. They also shared an importable template bot. DoorDash was used too but is not in our app list.

Act as my nutrition manager. My goal is [lose X lb by date] and my budget is [$ per meal]. Keep one plain file with: my daily weigh-ins, every meal as a low, likely and high estimate for calories and protein with how sure you are, my regular meals, and my current daily targets. When I ask for food, search [Uber Eats or my delivery app] for deals that fit the targets and build the cart, but stop and show me the cart before anything is ordered. When I send a menu photo, pick my order. Every [two weeks], compare my weight trend to what I ate, estimate what I actually burn, and propose new targets for me to approve before you change them.
