[Mameta Tama's Recommended Menu: Gapao Rice Set]

"I've tried many frozen bento boxes before, and honestly, it was always a given that eggs would turn out dry when microwaved. But with Muscle Deli's Gapao Rice, the fried egg remains perfectly runny even after microwaving. I was truly amazed that this runny texture could be replicated with a frozen meal. The taste is also delicious, and the calories and PFC are perfect for dieting. It's a dish I can confidently recommend."

Tie-up and Thoughts on Diet & Body Makeup

Comments from the Duo:

"When I received Muscle Deli's bento boxes this time, I was shocked by how delicious they were for frozen meals. While diet requires careful meal management, strict dietary restrictions are difficult to maintain. Muscle Deli is easy to use and delicious, making it sustainable, which is why I accepted this tie-up after 4 years, hoping many people will utilize it.

What we value in diet and body makeup is 'continuing to try a little harder than yesterday, without comparing yourself to others.' You don't need to aim for 100 points every day; even 50 points, if continued, will change your body and build confidence.

We ourselves lacked confidence in our physiques initially, but now our lives have changed dramatically, with 700,000 YouTube subscribers and having guided over 350 people in their diets. We want to continue conveying how body makeup can lead to a more positive life."
