I Made Him Eat Like Me for 30 Days (INSANE Results)

Jeremy Ethier puts his meal plan on Kevin, his head engineer, for 30 days. Kevin drops from 229 lb to 216.4 lb and loses 5 cm from his waist, nearly double the projected loss. The video shows early struggles with adherence and energy, then habit adjustments that made the diet stick.
Questions this video answers
229 pounds.
Approximately 600 calories per day.
4 to 6 pounds in 30 days (projected).
216.4 pounds.
About 12 pounds.
Recently, I shred down to 11% body fat with a meal plan I thought was pretty easy to follow. But then Kevin, our head engineer here, came up to me and asked, yo.
Think if I ate what you ate, I'd get the same results?
Which got me thinking, can the same meal plan really work for two people with totally different body types and lifestyles? To find out, for the next 30 days, Kevin's going to follow my exact meal plan. A will see just how much fat he loses and how you can use this plan as a cheat code for burning fat. Are you curious to see what's under these hoods? Yes. Your breakfast for the next 30 days is. What is that? This was my staple breakfast. Oats mixed with water. I pop it in the microwave and then I put it in the fridge overnight to harden and then top with Greek yogurt and some of our vanilla protein powder. Nice. Okay, so I should probably mention Kevin is actually an incredible cook. He's even helped us shape the flavor profile on our most popular protein powder. So as I'm about to have Kevin rank my meal plan, I'm honestly pretty nervous.
It actually kind of tastes like pudding.
You know, like banana pudding. Out of ten, you won't hurt my feelings.
Six.
Six. Okay. Thankfully, Kevin did seem to actually enjoy the rest of my meals, including chicken wraps with veggies for lunch, chicken salad with an apple for an afternoon snack, my personal favorite, peanut butter pad Thai for dinner, and then my Greek yogurt parfait for dessert. Believe it or not, this is more.
Than I thought than what I would.
Do get to eat. All right, Kevin, let's get your measurements. Kevin's starting weight is 229 pounds. And based on his current activity levels, this diet should put him in a deficit of 600 calories a day, hopefully resulting in 4 to 6 pounds of weight loss in 30 days. But we'll also be tracking Kevin's waist circumference. As researchers found once you reduce your waistline by at least 5cm, you unlock several health and cardiovascular benefits. And while 5cm is pretty probably too ambitious for a 30 day goal, I want to set Kevin up for long term success even after this diet is over.
Day one of Jeremy's meal plan. I'm going try one of his healthy peas. First week was like, I think the hardest. Your body obviously is adjusting to a whole lot of different things. Your calorie intake obviously probably dropping more on carbs, so you feel a bit more lethargic, especially during workouts. So the first week workouts were, like, terrible. This is rough. Squats are rough.
I think squats are, like, probably the.
The worst.
So part of Kevin's early struggles were my fault because he wasn't a fan of the first overnight oats I made him.
The first two batches that Jeremy made me, it was like. I don't know, there was, like a ton of stevia in there. It was. It tastes like a dessert.
Kevin was consistently choosing to skip breakfast, which means not only was Kevin in a higher calorie deficit than we were intending, but he was missing out on a big chunk of his daily carbs to fuel his workout and the rest of the day. After about a week, the carb stores in his muscles and liver will start getting depleted. This eventually leads to what's known in dieting as hitting the wall, where energy levels drop and you experience high levels of muscle fatigue and reduced performance in the gym.
The day is literally one week. Yeah, I can feel it clicking. It's like it's cliffing energy.
Just had lunch.
Honestly, I'm really, really tired and I'm just trying to eat some carrots to tide me over. I'm just so low energy right now.
It was now urgent. I found a way to get Kevin to actually integrate breakfast into his mornings. Otherwise, there's no way he's going to be able to make it through the full 30 days. But this wasn't going to be easy. Remember when Kevin said this, I think.
This would be more than what I.
Would get to eat. Well, it turns out this meal plan was way more food than Kevin's used to eating. As a busy engineer, once he starts coding, he doesn't even think about food until he gets home. Time to eat.
I kind of just only had Fair Life shake for lunch, and then for dinner, I would kind of eat whatever.
So not only did I need to find a way to change Kevin's habits around eating, but I needed to create a breakfast he actually enjoyed. So I decided to put my chef hat back on and test out some more overnight oats recipes. We're going to go with the apple cinnamon flavor, and we're also going to use my Bill Science Salted caramel protein powder. Wow.
I'd give this a 10.
Yeah. And by using members of our built with science team to make sure Kevin was remembered to eat every morning. And Kevin was quickly having his energy bounce back while continuing to lose weight. The whole thing?
Yeah, the whole thing. The whole thing. Wow. The whole thing. That's a lot of food.
That's more than you used to wow. Damn. 222 on the dot. So that's almost £7 in two weeks. Now, at this point you're probably wondering how the heck does someone switch from eating one meal a day to now eating five meals a day with way more food and yet end up losing weight? Well, it's all about picking the right foods that have a low calorie density and also fit your lifestyle and personal preferences. And here, Bill with science.

In the past couple of weeks, you mentioned that you've been kind of just avoiding.
Yeah, I know. I've been avoiding going out altogether. I've just played a lot more video games at home.
You know, just hanging out with the cat.
I don't know, man.
It's just. Kevin, that's, that's an area where we definitely want to improve. Because again, like, what is sustainable for you in the long run? Are you just going to live in a cave and not go out and sacrifice everything for it?
No.
I'm sure you can relate to Kevin's struggle of sticking to his diet on the weekends. In fact, research shows that even when people stay on track during the week, oftentimes they end up overeating so much on the weekends that they gain all the way back. So I understand Kevin's reservations about going out, but rather than say no to all social events every single weekend, I want to give Kevin a few of the secrets I use to personally enjoy going out without seeing all my progress disappear. So the first thing is just like give yourself the permission to have that meal and enjoy yourself. You know what I mean? You definitely want to avoid going out to a socially eaten occasion and being just ravenously hungry because this is where it sets you up for failure. So one of the things that you can do is preload your stomach with protein and some fruit and vegetables. You're already pretty satisfied, so it's going to reduce the likelihood that you actually go and Try to eat everything.
We're just at a sushi restaurant downstairs from our flight. This tastes so good. And that, Honestly, I really miss it. Okay, this is the last order, I promise. Right, Right. Yeah, last order.
Okay. So with Kevin now having the ability to enjoy his weekends while continuing to make progress on the scale, there's something else we've been neglecting that will be key to Kevin's long success. If you look at the research comparing diet versus exercise for fat loss, diet is a clear winner. In fact, in the past 15 days, we didn't change anything to Kevin's activity level. Kevin literally sits on his computer 10 hours a day, every single day. Yet the fat was quickly melting off just from his diet changes. But if we continue to neglect this, it's going to come back to bite us. Just being more active, taking more steps per day, it's not as good for fat loss as most people realize. It's actually not very effective. But it has been shown to be extremely effective for preventing weight regain. But in addition to getting Kevin moving around more, there's one more piece of the puzzle to ensure he doesn't regain the weight he loses. See, I couldn't possibly expect Kevin to stick to the exact same meals forever, even after the 30 days were up. This is why strict meal plans only work in the short term. But until you can't stand what you're.
Eating anymore, I really, really don't like chicken.
Research suggests you get the best success when your diet is tailored to your individual preferences. And luckily, with Kevin's skills in the kitchen, he was already one step ahead of me.
The first thing was I looked for the cleanest proteins. That was not chicken breast. I like seafood a lot, so I've got some tuna and I got some shrimp, both of which are pretty clean. I think that was the best swap. I did that on day two, and if I didn't do that on day two, I would probably be like, ah, screw this, because the chicken breast tastes like sandpaper to me.
Let's go.
This is the lobster bisque. It's just carrots, tomatoes, the lobster water, and some Greek yogurt. I've been a nasty girl. Nasty f. In a nasty.
I mean, you know, I'm filming, right?
So week three and four, it didn't feel like a meal plan or anything like that. It doesn't feel like, you know, I flipped my life upside down just to do this. You know, I can still get my work done. It's like, oh, you know, I'll just bring my lunch to Work.
Now, before I reveal the final results, if you guys want to give this same meal plan a shot yourself, I've created a free downloadable PDF of the full meal plan, as well as a list of substitutes you can use for each ingredient, just like Kevin did. You can download it in the link in the description box down below or just head to builtwithscience.com dietplan all right, it's time for the final weigh in. Top level 216.4. Holy crap. So that's down 12 pounds in 30 days. Now, while usually I wouldn't recommend losing weight so quickly, a lot of this is going to be water weight. And also, once we actually fix Kevin's diet, his rate of weight loss slowed down to a consistent 2 pounds per week. What's even more impressive is Kevin actually lost an entire 5cm across his waistline in just 30 days, which is a great indicator that the weight he did lose was mostly fat rather than muscle. And the visual results are pretty striking. Look closely at his face, jaw and neck. He. He's literally starting to look like a different human. Nice freaking go, dude.
Like, realistically, I don't think this is an end. I think this is like you guys filmed at the start.
