Big Breakfast Diet: A Diet That Works?
Stop me if you've heard this before... but before you click out, keep reading - it gets interesting. Eating a big breakfast with copious amounts of (gulp) carbs and protein, followed by a low carb, low calorie diet the rest of the day has shown some pretty promising results - and get this; obliterates the low carb only! This according to a new study presented at The Endocrine Society's 90th Annual Meeting in San Francisco.
I will now attempt to break this down in the simplest terms possible (so that I can understand what I've written).
According to the study's lead author, Daniela Jakubowicz, MD, of the Hospital de Clinicas, Caracas, Venzezuela - the key to successful long-term weight loss diet depends on its ability to increase a sense of fullness and bring down carb cravings. Jakubowicz claims that strict low carb diets exacerbate carb cravings and fail long term. Here are the details of the study:
Participants: 94 Obese, inactive females.
Group I: Very low carb dieters
- 1,085 calories a day.
- 17 grams of carbohydrates
- 51 grams of protein and
- 78 grams of fat a day.
- The smallest meal was breakfast, at 290 calories. For breakfast the dieters were permitted only 7 grams of carbohydrates, such as bread, fruit, cereal and milk. Dieters could eat just 12 grams of protein, such as meat and eggs, in the morning.
Group II: Big breakfast dieters
- 1,240 calories a day.
- 58 grams of carbohydrates
- 93 grams of protein
- 46 grams of fat
- Dieters ate a 610-calorie big breakfast, consisting of 58 grams of carbs, 47 grams of protein and 22 fat grams. The diet schedule for lunch was 395 calories (34, 28 and 13 grams of carbs, protein and fat, respectively); dinner was 235 calories (5, 18 and 26 grams, respectively).
The Results
The first 4 months of the 8 month study focused on weight loss, while the last 4 months focused on weight maintenance. Here were the results:
First 4 months:
Very low carb group: Average 28 lbs loss
Big Breakfast group: Average 23 lbs loss
After 8 months:
Very low carb group: Regained 18 lbs
Big Breakfast group: Lost an additional 16.5 lbs
The big breakfast group lost an average of 21% body weight while the very low carb group lost only 4.5%.
What to make of this
I personally was shocked at the disparity between groups. The regain in the very low carb group seems consistent with other longer-term studies (although those studies still show a better net loss in the low carb group). One thing that is glaring in the study is how much more protein the big breakfast group was eating - my guess is that protein is the key. Both diets are low in calories and carbs, so it would only make sense that the higher protein big-breakfast eaters would have better satiety and would therefore be able to sustain this type of diet.
I would like to see this study duplicated in a free feeding (ad libitum) situation - keep the ratios the same but do not restrict calories.
Conclusion
Keep protein high enough to thwart hunger, keep carbs low enough to keep insulin in check (but not too low) and eat a big breakfast (or don't). Oh, and don't forget to exercise!

It's a well known fact that eating a good breakfast helps with weight loss and protein takes a long time to break down in your body so makes perfect sense to me, thing is there are that many studies saying this and that who has time to keep swapping and changing.
If something works for you keep at it as the saying goes KISS keep it simple stupid.
ReplyIt's a relatively small study so I would like to see if the findings would be the same in a bigger trial. But I think it's definitely about the protein here. And I know personally, breakfast with protein, fiber, and some good fats help me stay full well into the day.
ReplyThose numbers don't add up! If you add up the grams of carbs per day for the big breakfast group you get 97, not 58 (58 + 34 + 5). I think this is relevant when comparing the diets.
ReplyEven though the sample size is small the results are vastly different between the two groups and would suggest statistical significance. I think it makes great sense and am not really surprised by the findings.
Replyi dont eat breakfast every day but on the days i do, i always choose a lot of carbs because i know that if i eat breakfast, i'll never be hungry for lunch. needing the energy from the carbs to last me all day, this makes perfect sense if you indulge in a high carb breakfast and restrict them during snacks and other meals, you feel a little bit less lethargic starting up- and your appetite is not as fierce throughout the day.
ReplyThis one is truly a mess...so many confounding variables to deal with, it really can't be said one way or the other what happened!
We've got more calories, more protein, different macronutrient ratios, more and less carbohydrate and fat, no clue about actual foods consumed, no clue about micronutrient intakes, no idea what either was told to do during the maintenance phase that led one group to gain and the other to continue losing...oy!
That said, both diets were low-calorie and low-carb too....97g in the big breakfast group is still low-carb.
The other issue is that this was a poster presentation, led by a researcher specifically promoting her particular diet book that this study was based upon....no peer review of the data or conclusions.....so until it's replicated, I don't hold the results all that highly.
ReplyWe take the kids out for a big breakfast about once a month. Breakfast includes eggs, toast, hashbrowns, and some type of breakfast meat. I know that I feel stuffed for the rest of the day and don't want to eat another thing.
Maybe the saying "eat breakfast like a king, lunch like a prince, and dinner like a pauper" might have some merit.
ReplyThis is an interesting study. I've always read that the low-carb diet is hard to maintain over the long-term. The idea behind this seems reasonable, but like some other, I'd like to see more studies performed with similar results.
ReplyI have always found that this works for me. But I would rather up the protein go easy on the carbs. I find that when the carbs gram count is high I crave carbs a whole day.
ReplyOk, look at the total calorie numbers and the interest in this story goes away. 610 calories is not a "big breakfast" by Western definitions and 1240 calories fits within the modern idea of highly restricted. I've seen this study get enormous amounts of press and excitement, but seriously. There is nothing new here. 1200-1500 has been shown to be more effective than tighter restriction for weight loss. How you skew the calories simply may or may not be relevant.
ReplyThe big breakfast group ate more calories per day, that could have helped them feel slightly more full, they also ate more grams of protein. For both groups those calories seem extremely low to me.
When are we going to stop promoting super low calories levels that are impossible to maintain long term without turning into a zombie? Never, it was a rhetorical question.
ReplyThis study didn't compare low carb to big breakfast, it compared low CALORIE to big breakfast. Low carb eaters typically eat big breakfasts, eat more calories, & DON'T eat bread
Seems to me the low carb group was intentionally mis-named in order to discredit low carb diets.
ReplyThe study is a big mess. What were they trying to compare: high-carb vs. low-carb; big breakfast vs. little breakfast; high protein vs. moderate protein; low calorie vs. severely low calorie; a little of everything?
Why would you ever design the study this way?
ReplyThanks Mike. Fantastic breakdown and summary.
ReplyWho did this study; a group of grad students that have no clue how to set up an experiment?? Anyone in the research field knows that in order for a study to have any merit, you need to have only one variable at a time. This study varied total calories, carbohydrate count, fat count, how many calories were consumed at breakfast, etc. Also, how were the rest of the day's calories consumed? Did the small breakfast eaters eat a lot at lunch? Dinner? What about the big breakfast group? Did the very low carb group stick to the diet after the initial 4 months, or did they relax a bit on their regimen? Did the groups exercise?
Anyways, rant over...I usually find that when I eat a high protein breakfast, I stay full longer than if it's just carbs. I like a yogurt with oatmeal and some fruit...the fiber plus the protein and the complex carbs keep me going all morning long. But the truth is, you have to watch your total calorie intake as well...this study restricted calories in both groups, which would probably cause weight loss in just about anyone.
