Ask The Muscle Prof: ''What Are The Ideal Macros For My Breakfast?''
Perfect Morning Macros
for my breakfast?"
I'm confused about what I should eat for breakfast. What does the science say about the ideal macros for the morning?
Perhaps more than any other meal, breakfast is at the mercy of our daily routine—or lack thereof. Even those of us who have heard that it's "the most important meal of the day"—i.e., all of us—can sometimes be found skipping it while we panic to get out the door. Or we'll dip doughnuts into coffee and assume it's better than nothing. Or we'll pack in large servings of whole grains in the hope that they'll give us "long-lasting energy throughout the day."
I'm here to say that the aura around breakfast is well deserved, and that skipping it is bad news. Studies have found that people who don't eat breakfast tend to overeat during the rest of the day and have more body fat overall.1,2 In addition, research has shown that what you eat at breakfast determines how well your metabolism functions for the remainder of the day—for better and worse. As you might expect, then, breakfast can also be geared strategically to your goals. Since your goals include losing fat, building muscle, and achieving a healthy body composition, let's dig into the perfect macros for the morning.
Protein: Get Enough!
As you might expect, anabolism (protein synthesis) is at its lowest and catabolism (muscle breakdown) is greatest after an overnight fast.3 This is significant. Americans typically consume most of their protein at lunch and dinner, with only insignificant amounts at breakfast. Research has found a threshold amount of protein, 30-40 grams' worth, that must be consumed to both trigger muscle protein synthesis.4 This amount is far above what you'll get from a typical American breakfast of a bagel, cream cheese, and orange juice. Eat like that, and you set yourself up to remain in a catabolic state!
Aside from the anabolic benefits of protein, research has shown that consuming higher-protein breakfasts makes individuals feel fuller throughout the day, all while burning more fat than with lower amounts of protein.5,6 Accordingly, I recommend 30-40 g of high quality protein at the first meal of the day.
Carbohydrates: Speed Kills
The quality of the carbs you eat at breakfast seems to matter as much or more than the quantity, within reason. Your choices? Fast-digesting carbs in the form of sugars, starches, and flours; or slow-digesting fibrous carbs like oatmeal. Dr. Stevenson investigated this question by studying subjects who ate a fast-digesting or slow-digesting breakfast three hours before performing exercise7. Fat burning was 2-3 times higher in the slow-digesting carbohydrate than the fast-digesting meal. In addition, high-fiber, low-glycemic breakfasts can contribute to satiety over the course of the day8. Fast-digesting carbs, as their name implies, tend to leave you hankering for more of the same junk food far too soon.
Don't Forget the Fat!
Do you think cutting back on trashy carbs in the morning means you skimp on fat too? Think again. Researchers from the University of Alabama at Birmingham performed a series of experiments where subjects were fed either a high-fat breakfast (45/35/20 percent fat, carbs, and protein), or a high-carb, low-fat breakfast (10/70/20). The high-fat breakfast was followed by eight hours of high-carb eating (10/70/20) while the high-carb breakfast was followed by eight hours of high-fat eating (45/35/20). This continued for 12 weeks.
Astoundingly, even though the total macros were similar between groups, subjects who ate a high-fat breakfast burned more fat throughout the day, and they were leaner than the high-carb breakfast eaters! The takeaway is that breakfast programs your metabolism for the rest of the day. A high-carb breakfast will cause you to rely primarily on carbohydrates for energy the rest of the day, whereas a higher-fat, lower-carbohydrate breakfast will program your metabolism to run on fat.
Your Macro Menu
To halt catabolism, maximize muscle anabolism, and improve fullness for the rest of the day, I recommend you take in roughly 30-40 grams of high quality protein at breakfast from sources such as eggs and dairy. A large egg and a 6 oz container of whole-milk yogurt both contain around 6-8 grams, so do the math. Furthermore, a low-to-moderate amount (<30 grams) of low-glycemic carbs, and a higher percentage fats (about 20 grams, or 40-45 percent of the total breakfast calories), seems like the perfect balance to encourage a lean, muscular body composition.

I believe he means 40-45% of your total breakfast calories should consist of fat. For example, if your breakfast consists of 500 calories, about 200-225 calories should be from fat.
Fat does not make you fat. :) I have seen some very ripped people who eat almost an equal fat/protein split with minimum carbs.
Yes, thats what the data says Orb85750, you will lose fat by doing this
This. It isn't relevant. It is all what you have been telling your body. I started skipping breakfast and started consuming my macros in the afternoon and evening and I have been slowly losing fat and gaining strength in the gym.
Not everyone is the same. I believe a little meal timing is relevant. I'm not going to sit here and say I eat every 2 hours, but I try to time some of my meals accordingly to boost my metabolism. IE Breakfast, pre w/o, post w/o meals.
Depends on what you are trying to do. For the average gym rat looking to keep a good shapely body, timing is a low priority. If you are looking to be the muscle bound, headed for the Olympia stage, then timing is a high priority.
In either case, you just need to make sure that the fuel reserves are there for when they need to be used. Eating 7-8 meals a day and training has it benefits, so does eating 3-4 meals a day and training. I've done both and frankly I love eating huge meals over eating all day.
Good article. I tend to stay away from any sorts of sugars in the AM. Breakfast consists of (EGGS,MEAT PROTEIN,NUTS,VEGES AND GREEN TEA) .... I grab my high carbs and fruit sugars etc later in the day.
Continue the great work Mr. Wilson.
Seems like an unfair recommendation to make. It's based on several different studies that are unrelated to each other... it just takes a piece from each one while there's no study or science behind the actual recommendation itself.
But anyway, very good and interesting read. I think the most important point made is that people should eat quality protein at breakfast, as opposed to a **** protein shake. So many people living off of whey.
Keep in mind, when living on a strict wallet diet, protein is protein. With the little money I get to spend on my health currently, I could care less if I get my protein from eggs, a shake, or a fillet mignon.
Never truer words there BigMiniBaby.
I always say I'm building on a budget, and truly protein is protein and if you are not looking to be muscle bound to Olympia, then the real minute details are not really all that detail.
Basic protein math, 1g per lb of body weight.
It depends when you workout and what you eat throughout the day. Are you able to hit your macro needs by eating this breakfast? Are you cutting? bulking? Training for a specific sport?
Seems pretty lean to me, might be picking up some cals with that choc milk but other than that, you are low on carbs and cals.
Like he said above though it depends on what you are looking to do, if you are cutting then this seems perfect, but then again I would like see what your training is consisting of.
