The BEST Science-Based Diet for Fat Loss (All Meals Shown!)

If you want to learn of the best evidence-based diet to lose fat, then you need to read this article.

When it comes to fat loss (or “cutting”), there’s no doubt that your diet is the most important factor you have to get right. Even if your training is on point and consistent, you’re simply not going to see the results you want without a proper nutrition strategy.

Yet this is where most people fail. And I honestly don’t blame them. We’re constantly overwhelmed with new “fat burning diets” that are supposedly the new best diet to lose weight. So it becomes extremely difficult to know which approach to take.

But the real truth is, every single diet (Check out this muscle building diet article) or dieting method out there works the exact same way. They ALL achieve fat loss by causing you to eat at a caloric deficit.

Calorie intake vs calories burned

Meaning that you’re eating less calories than you’re burning everyday.

Research has time and time again proven this idea. That whether it’s keto, intermittent fasting, paleo, and so on, although these diets may each have certain psychological and physiological benefits – none of these diets or methods have any “special fat loss effect.” They instead work by making it easier for you to eat less calories.

Thus, the best diet to lose fat is the one that you personally enjoy the most and will be consistent with.

But.. there’s a few things you have to get right within that diet if you want to see the best fat loss results.

Before that: if you’re looking for a training program that’ll always help you take care of the most important things for fat loss (and muscle growth), I’ve got just the thing for you. Every BWS program is designed to be an all-in-one, science-based process that’ll get you to your dream physique FAST. And best of all? It’s all rooted in science. For more information:

How to Optimize Your Diet for Fat Loss

There are a few factors you need to get right in order to optimize to lose fat, and are mainly how much of the following you consume on a daily basis:

  • Total Calories
  • Protein
  • Carbohydrates
  • Fat

So how exactly do you optimize each of these factors for fat loss?

1. Calories

If you want to maximize fat loss while minimizing muscle loss, then you have to pay close attention to how many calories you’re intaking. And in this case, more is definitely NOT better.

Research indicates that a moderate calorie deficit that enables you to lose around 0.7% of your bodyweight per week (~1lb of weight loss per week for most people) is ideal. In fact, a more aggressive calorie deficit was shown to hinder fat loss as opposed to accelerate it. Although you may lose more weight with a larger deficit, we want to maximize FAT loss rather than WEIGHT loss. Focusing on the latter will just lead to a “skinny-fat” physique with little muscle definition.

And if you’re unaware of what your calorie intake should be, a good starting point and something recommended from a 2014 paper by Eric Helms and colleagues, is to simply “multiply your bodyweight (in lbs) by 13.”

So for a 170lb individual, your daily calorie intake would be somewhere around 2210 calories per day (170 x 13 = 2210 calories).

Although this won’t be spot on for everyone, you can start with that and then increase or decrease your calories based on how your weight loss progresses throughout the next little while.

2. Protein

As for protein, it’s the most important macronutrient you want to keep track of. Research has repeatedly shown that it plays a major role in maintaining muscle while you’re in a calorie deficit.

And although how much protein you should intake will always be a highly debated topic, a recent 2018 meta-analysis from the Journal of Sports Medicine found that intaking at least 0.73g/lb of bodyweight is enough to maximize muscle growth and maintenance.

However, I personally find that intaking a little more than this (~1g/lb) is beneficial when restricting calories since we know that protein is the most satiating macronutrient, so it can better help keep you full throughout the day and it just acts as a buffer to help minimize any possible muscle loss.

3. Carbs + Fat

Now as for carbs and fats, despite the ongoing debate between low fat versus low carb diets, a recent 2018 year-long randomized clinical trial with over 600 subjects, found that:

When protein intake is equated, both low-fat and low-carb diets are equally as effective for fat loss.

So in reality, these two factors are of lesser importance than your total calories and your daily protein intake and can therefore be adjusted based on what kinds of foods you personally enjoy.

But generally, the literature recommends a fat intake of around 0.25-0.5g/lb of bodyweight from healthy fats and then the rest of your calories, minus your protein of course, coming from carbs.

Research does also suggest that females might do better sticking to the higher end of that fat range, so that’s something to keep in mind as well.

So as an example of how you could set up your diet  factoring a, 170lb male would require:

Total Calories: 170lbs x 13 = ~2,210 calories per day

Protein: ~170g ( 170g x 4 = 680 calories since protein has 4 calories per gram)

Fats (using the middle of the recommended range): 170lb x 0.4 g/lb = 68g (68g x 9 = 612 calories since fat has 9 calories per gram)

Carb (whatever is left over): 2,210 calories – 680  calories protein – 612 calories fat = 918 calories of carbs (918 calories / 4  = 230g carbs since carbs has 4 calories per gram).

So, the individual above would need roughly 170g protein, 68g fat, and 230g carbs which totals to around 2,200 calories per day. Voila!

Now that you’ve learned the basics regarding setting up and optimizing your diet for fat loss, let’s take a look at what a typical day of eating at a calorie deficit looks like for me.

The Main Goals

So before we get started with the first meal, here are the main goals I try to achieve with my diet (which you should strive to achieve as well):

Goal 1: Hit my calorie and macronutrient goals.

This is what I previously discussed, and currently my main focus is to intake roughly 2,300 calories and around 165g of protein a day. The amount of fats and carbs I intake vary but are within the recommendations I previously went through.

Goal 2: Have fruits/veggies with every meal.

This simply helps keep me full since fruits and veggies are often low in calories, and they help me minimize any micronutrient or fibre deficiencies.

Goal 3: Space out protein throughout the day (ideally 4 meals).

is a good idea for optimizing daily protein intake, since as shown in Brad Scheonfeld’s 2018 study, in order to maximize muscle anabolism, your daily protein intake should ideally be spread across a minimum of four meals throughout the day.

Goal 4: Stick mostly to unprocessed foods while incorporating foods I personally enjoy.

This is vital for my overall well-being and adherence to the diet – which in fact will be the most important factor regarding your success with it!

So with that being said, let’s start with meal 1.

Meal 1: Breakfast/Pre-Workout (9:00 a.m.)

(450 calories: 30g protein, 67g carbs, 6g fat)

meal 1 - breakfast for fat loss

My breakfast usually consists of a smoothie with the following ingredients:

  • Fruits and flaxseed for my micronutrients, fibre, and omega-3 (ALA) intake
  • Cashew milk since it’s much lower in calories than dairy milk yet still provides calcium and vitamin D
  • Whey isolate protein to contribute to my daily protein intake
  • A few grams of cinnamon which helps add taste and has quite a bit of research supporting its ability to improve insulin sensitivity

With my smoothie I usually have rice cakes and the other half of the banana. I prefer this as my pre-workout meal since it consists of a fast digesting protein and high glycemic index carbs, which as explained in my pre-workout meal video, seems to be ideal for performance based on the literature.

pre workout meal

But in any case, getting in some form of carbs before your workout is something I’d highly recommend unless you’re fasting of course.

Meal 2: Lunch/Post-Workout (1:00 pm)

(500 calories: 42g protein, 80g carbs, 2g fat)

Now as for your post-workout meal, contrary to popular belief, and as shown in this 2013 literature review on the topic:

Consuming a meal immediately post-workout doesn’t seem to be very important if you’ve had a pre-workout meal with sufficient protein.

But since you want you do want to space out your protein intake, having another meal at least within a few hours after your workout would be recommended.

I personally prefer keeping it simple with ~12 oz baked (microwaved actually) sweet potato, 4oz baked chicken breast, and a large salad on the side with low calorie dressing.

post workout meal

Again, simply sticking to unprocessed foods that help contribute to my overall micronutrient intake for the day.

Of course, you’re not going to want to eat the same meal every single day – no matter how hard you wish to lose fat. Don’t worry. Our 3-on-1 coaching program can help. You are going to have a dietitian who’ll customize your meals (varied and delicious!) to suit your training goals. Plus, your coach and I will also be available to guide you every step of the way.

Mid-Day Snacks (1:00 pm to 6:00 pm)

(250 calories: 2g protein, 59g carbs, 0g fat)

Throughout the day I usually have a few more servings of various fruits and vegetables and a combination of black coffee and green tea. These are all quite low in calories yet help keep me full until my next meal.

snacks during the day

The caffeine in green tea and coffee is a natural appetite suppressant, and has been shown to increase your caloric expenditure. Research from the Journal of Clinical Nutrition suggests that a few cups of coffee can lead to an additional 80 or so more calories burned throughout the day – which is actually quite promising! Keep in mind that this effect will likely diminish as you gain caffeine tolerance. But, it’s still better than nothing.

This, and the fact that research shows that caffeine may also increase fat usage by the body makes it something I’d recommend incorporating in your diet if you enjoy it.

Meal 3: Dinner (6:00 PM)

(560 calories: 55g protein, 49g carbs, 16g fat)

Sushi is by far my favourite food so I tend to have it quite often. The great thing about knowing how much you should be eating is that you are able to fit in foods that you enjoy without it affecting your progress.

sushi for dinner

Now aside from being a relatively low calorie, high protein choice, the salmon helps provide the important omega-3 fatty acids DHA and EPA. These fatty acids have recently been shown in a 2018 literature review  to possibly help with anabolic signalling and muscle repair and growth. So intaking a few servings of fish per week or supplementing with omega-3’s is something I’d highly recommend.

Meal 4: Late Night Meal (10:00 PM)

(560 calories: 42g protein, 34g carbs, 28g fat)

This is something I’ll typically have shortly before bed since I personally enjoy going to bed feeling full and it doesn’t impact my sleep. It’s usually a combination of eggs, egg whites, toast, peanut butter topped with stevia sweetener, and a salad with 0 calorie dressing.

late night meal

And for those against eating this late, the literature has shown time and time again that eating carbs or even food in general late at night will NOT contribute to fat gain given that you’re still staying at a calorie deficit.

Something I do want to mention though is that for very calorie-dense foods like peanut butter, I would highly recommend that you take the time and effort to at least measure or even better weigh out how much you’re using.

Several studies have shown that under-reporting calories is a very common reason why overweight individuals struggle to lose weight despite dieting. Which is probably because it’s so easy to do.

For example, here’s 300 calories worth of peanut butter compared to 100 calories – the difference is almost unnoticeable.

peanut butter comparison

Yet this can easily be the factor that’s inhibiting your fat loss.

So if you have any measuring tools, use those, otherwise here’s a link to a very affordable scale that I personally use myself.

Total Calories/Macros for the Day: 2,300 calories (171g protein, 277g carbs, 54g fat)

So that’s pretty much what a day of eating for fat loss looks like for me. Hopefully this provides you with some insight as to how to approach and optimize your diet for fat loss. The key is to incorporate foods you personally enjoy eating in order to create the diet that you can adhere to the best.

  1. Hey Jeremy, first of I want to thank you for all of your videos, the were very helpfull to me. I want you to help me with my calories because i am struggling to calculate them because of the activity levels. I am 25 years old, 82kg (180 pounds), 185cm (6 feet 53⁄64 inch).
    I spend most of the day sitting on a chair. For workout I do weigh lifting 4 times a week for around 50 minutes, and 1-2 times intense cardio for about 20 minutes. My bodyfat is around 20%. What is my TDEE? Thank you for your time and greetings from Greece!

    1. I would suggest using a TDEE calculator online then monitor your weight and see how it responds. I personally use a nutrition software that I made which shows me exactly what my TDEE is from my own data, which will be released as part of my online programs.

  2. Hey Jeremy, great article as usual but I think something got lost in the language. The discussion is about fat loss, thus a calorie deficiency in one’s diet is the goal. However you use numbers to calculate the daily calorie intake and then base all the macros and meals off those numbers but it’s never clear if that calculation was based on a weight loss diet or just regular body maintenance. I guess the clarifying question to be asked:

    Is the 13x body weight = daily calorie intake for fat loss?
    or is it:
    13x body weight = daily calorie intake for maintenance?

    If it’s the first, then all the numbers here make sense. But if it’s the second, then shouldn’t your calculations for your macros and daily calories be about 200-500 calories less? So using your example, 170lbs male * 13 = 2210 calories maintenance – 200 calories (weight loss) = 2010 calorie intake daily. Shouldn’t this be what your plan aims for if your goal is weight loss at 170lbs?

      1. Hello Jeremy

        checked your page i like it because is not about suffering 🙂
        Im 235lbs… 72 inch tall – this is the reason need to start a diet and exercises
        Based on your calculation it means for losing fat i should eat 3055 calories a day (with the specific number of protein, carb and fat)??
        It seems to much for me and comparing to other diets

        let me know, thanks a lot

      1. When you do, can you please make it Vegetarian/Vegan. That would be a tremendous help. Thank you, Jeremy. This stuff is great!

    1. What I presented can be used with any “diet” or “dieting method”. For example, I regularly employ intermittent fasting with the meals shown in this article.

  3. hi jeremy

  4. Hey Jeremy,
    Should I Subtract the amount of calories burnt in my workouts from my daily calorie intake?
    Thank you

    1. No need – that just overcomplicates things. Keep your workouts consistent and you can make changes with your calories based on how your weight changes.

  5. You ought to be prepared and can earn some lasting modifications for your own life, also also ascertain your self too nicely.

Exercise can let you burn excessive calories and fat also in addition have lots of health and fitness gains. It can bolster the cardio vascular systemand decreases blood pressure and also promotes mood also.

  6. Maybe this is for a different article, but can you explain the different types of protein you should take and when? I typically use a Whey protein for my post workout and a Casein protein as a shake right before bed. Does this matter significantly?

    1. It’s not significant, but there is some minor differences. I’ll make a future video on the topic.

  7. Hey Jeremy
    I want to Thank you for producing this great content. With the help of a similar diet of yours, I’ve reached a body fat percentage of 9,7%. I want to maintain that body fat percentage for a while before I start lean bulking. So should eat at my maintenance, or still be on a caloric deficit in order to maintain my body fat?

    1. Technically you would eat at maintenance – but the problem is you’re likely doing less cardio and weigh less now, meaning that your maintenance is not what it used to be. So eat a little less than your old maintenance and monitor how your weight changes.

  18. Hi Jeremy,
    I hope you still check these (lol). Anyway, how long before your workout do you eat? 1 hour? 2 hours? I’m starting the program this week and part of my workouts will be at the gym in my office so I’m trying to plan out my meals ahead of time.

    Many thanks!

  19. Hi,
    I have a question about the units. In the picture of peanut butter, the unit in the text is 300 calories. In the picture, it is 300 Kcal. Does that means 300 K calories, which is 1,000 times more. There are some other places with the unit of cal and Kcal. Would you please clarify??
    Overall, good article with lots of information.

    Thank you!
