Rebecca Pinto, a physiotherapist, nutritionist and the founder of Dr Rebecca’s Physiotherapy, has shared an innovative way to lose weight before the new year - by using ChatGPT! In an Instagram video posted on November 10, she shares a simple, two-step prompt breakdown for ChatGPT, that not only calculates your BMR, TDEE and ideal macros accurately, but also generates a customised diet plan tailored to your food preferences and meal timings.

Step 1: Calculate BMR, TDEE, macros

As per Rebecca’s instruction, ask ChatGPT to calculate your Basal Metabolic Ratio (BMR), Total Daily Energy Expenditure (TDEE), and ideal macro breakdown by providing your age, gender, height, weight and your lifestyle activity level.

Here is the prompt she used:

Calculate my BMR, TDEE, and ideal calorie + macro targets for fat loss.

I’m a [age]-year-old [male/female], [height in cm], [weight in kg], [activity level: sedentary / light / moderate / active].

I want to [lose fat].

Step 2: Personalised diet plan

Once you’ve entered the prompt and got your calculations, Rebecca suggests following up by requesting a personalised diet plan from ChatGPT. She recommends covering the following areas:

1. The number of meals you eat - breakfast, lunch, dinner, maybe a snack in between.
2. When is your hunger the maximum?
3. Your dietary preferences.
4. Whether you are a vegetarian, non-vegetarian, eggetarian, etc.

Rebecca states, “Now based on this you will get a diet plan that could actually help you lose weight. If you want more meal options, you can always put that prompt too.”

Here’s the prompt she used:

Based on my TDEE and calorie target of [___ kcal], make me a fat-loss diet plan.

I eat [number] meals a day at these times: [list times].

My hunger is highest around [time].

I like [foods you enjoy] and dislike [foods you don’t].

I’m [veg / non-veg / eggetarian / mix].

I want the plan to be practical and Indian, using easily available ingredients.
