QUESTION: Tom, Is it possible to not lose body fat because you’re eating too little?
-Linda

ANSWER: Yes and no. This gets a little complicated so let me explain both sides.

Part one of my answer: I say NO, because if you are in a calorie deficit you WILL lose weight.

Most people have heard anecdotes of the dieter who claims to be eating 800 calories a day or some starvation diet level of intake that is clearly in a deficit and yet is not losing fat. Like the mythical unicorn, such an animal does not exist.

Every time you take a person like that and put them in a hospital research center or metabolic ward where their food can be counted, weighed, measured and almost literally “spoon fed” to them, a calorie deficit always produces weight loss.

There are no exceptions, except possibly in rare diseases or mutations. Even then metabolic or hormonal defects or diseases merely lead to energy imbalance via increases in appetite, decreases in energy expenditure or changes in energy partitioning. So at the end of the day it’s STILL calories in versus calories out.

In other words, NO – it’s NOT your thyroid (unless you’ve got a confirmed diagnosis as such…and then guess what… it’s STILL calories in vs calories out, you’re just not burning as many as someone should at your height and weight).

One famous study that was published in the New England Journal of Medicine years ago proved this point rather dramatically. After studying obese people – selected specifically because they swore they were eating less than 1200 calories but could not lose weight – Steven Lichtman and his colleages at St. Luke’s Roosevelt Hospital in New York came to the following conclusion:

“The failure of some obese subjects to lose weight while eating a diet they report as low in calories is due to an energy intake substantially higher than reported and an overestimation of physical activity, not to an abnormality in thermogenesis.”

That’s right – the so-called “diet-resistant” subjects were eating more than they thought and moving less than they thought. This was probably the single best study ever published that debunks the “I’m in a calorie deficit but I can’t lose weight” myth:

Part two of my answer, YES, because:

1) Energy intake increases.

Eating too little causes major increases in appetite. With hunger raging out of control, you lose your deficit by overeating. This happens in many ways, such as giving in to cravings, binge eating, eating more on weekends or simply being inconsistent, so some days you’re on your prescribed 1600 calories a day or whatever is your target amount, but on others you’re taking in 2200, 2500, 3000 etc and you don’t realize it or remember it. The overeating days wipe out the deficit days.

2) Metabolism decreases due to smaller body mass.

Any time at all when you’re losing weight, your metabolism is slowly decreasing due to your reduced body mass. The smaller and lighter you get, especially if there’s a large drop in skeletal muscle mass, the fewer calories you need. So your calorie deficit slowly shrinks over time as your diet progresses. As a result, your progress slows down even though you haven’t changed how much you eat.

With starvation, you always lose weight, but eventually you lose so much weight/body mass that you can reach energy balance at the same caloric intake you used to lose weight on. You might translate that as “I went into starvation mode” which wouldn’t be incorrect, but it would be more accurate to say that your calorie needs decreased.

3) Metabolism decreases due to adaptive thermogenesis.

Eating too little also causes a starvation response (adaptive thermogenesis) where metabolic rate can decrease above and beyond what can be accounted for from the change in body mass (#2 above). This is “starvation response” in the truest sense. It does exist and it is well documented. However, the latest research says that the vast majority of the decrease in metabolism comes from reduced body mass. The adaptive component of the reduced metabolic rate is fairly small, perhaps 10% (ie, 220 calories for an average female with a 2200 TDEE). The result is when you don’t eat enough, your actual weight loss is less than predicted on paper, but weight loss doesn’t stop completely.

There is a BIG myth about starvation mode (adaptive thermogenesis) that implies that if you don’t eat enough, your metabolism will slow down so much that you stop losing weight. That can’t happen, it only appears that way because weight loss stops for other reasons. What happens is the math equation changes!

Energy balance is dynamic, so your weight loss slows down and eventually stops over time if you fail to adjust your calories and activity levels in real time each week.

I teach a system for how to adjust calories and activity weekly using a feedback loop method in my Burn The Fat, Feed The Muscle program (more info from www.BurnTheFat.com)

So what can be done to stop this metabolic slowdown caused by low calorie dieting and the dreaded fat loss plateau that follows? I recommend the following 5 tips:

1) Lose the pounds slowly.

Slow and steady wins in long term fat loss and maintenance every time. Rapid weight loss correlates strongly with weight relapse and loss of lean body mass. Aim for one to two pounds per week, or no more than 1% of total body weight (ie, 3 lbs per week if you weigh 300 lbs).

2) Use a higher energy flux program.

If you are physically capable of exercise, then use weight training AND cardio to increase your calorie expenditure, so you can still have a calorie deficit, but at a higher food intake (also known as a “high energy flux” program, or as we like to say in Burn The Fat, “eat more, burn more.”)

3) Use a conservative calorie deficit.

You must have a calorie deficit to lose fat, but your best bet is to keep the deficit small. This helps you avoid triggering the starvation response, which includes the increased appetite and potential to binge that comes along with starvation diets. I recommend a 20% deficit below your maintenance calories (TDEE), a 30% deficit at most for those with high body fat.

4) Refeed.

Increase your calories (re-feed) for a full day periodically (once a week or so if you are heavy, twice a week if you are already lean), to restimulate metabolism. On the higher calorie day, take your calories to maintenance or even 10, 15, 20% above maintenance and add the extra calories in the form of carbs (carb cycling). The leaner you get, and the longer you’ve been on reduced calories, the more important the re-feeds will be. (You can learn more about this method in chapter 12 of Burn The Fat, Feed The Muscle at www.BurnTheFat.com)

5) Take periodic diet breaks.

Take 1 week off your calorie restricted diet approximately every 12 weeks or so. During this period, take your calories back up to maintenance, but continue to eat healthy, “clean” foods. Alternately, go into a muscle building phase if increasing lean mass is one of your goals. This will bring metabolism and regulatory hormones back up to normal and keep lean body mass stable.

There is much confusion about how your metabolism, hormones and appetite mechanisms are affected when you’re dieting, so this was really one of the most important questions anyone could have asked.

If this didn’t REALLY click – then you may want to save this and read it again because misunderstanding this stuff  leads more people to remain frustrated and stuck at plateaus than anything else I can think of.

Get Muscle Specialization Secrets

I’m often asked what my body measurements are and/or what are the ideal measurements for a bodybuilder or a classical muscular male physique. Believe it or not, there are actually many formulas for determining the “ideal body proportions.” On the other hand, you might want to take them with a grain of salt…

ANSWER: Personally, I no longer take my measurements, although I did regularly when I was a teenager. I do, however think it’s a great way to chart progress. Circumference measurements give you feedback about how well your training (and nutrition) regimen are working and let’s you catch yourself if certain body parts are lagging behind others, or in the case of waist and hips, if you’re gaining body fat.

The waist measurement is an important one, because when your waist circumference is going down, you know your overall body fat is going down. Also, when your waist shrinks even a little bit, it tends to completely change the way you look – even if you don’t gain any muscle, a narrow waist creates an illusion of broader shoulders. Abdominal fat and a large waist measurement is also a health risk.

There have been all kinds of different formulas proposed over the years for the “ideal proportions”, but I never aimed for a certain measurement myself. Bodybuilding is a very visual sport. The judges don’t come up on stage and measure your arms in a bodybuilding contest – you are judged on appearance.

I’ve always gone after a certain “look” as opposed to a certain measurement. I cut out photos of bodybuilders whose physiques I admire and want to emulate and rather than having a measurement in mind, I always have a picture of my ideal in mind.

On top of a solid base of muscle size, I simply work towards symmetry, so all muscles are developed equally, with no single muscle groups that are out of proportion compared to others – for example, a huge chest and rib cage with small arms looks silly – huge arms and small legs looks un-symmetrical as well.

I’m not all that hung up on weighing a certain amount either, although I do weigh myself regularly. The main reason I monitor my weight closely is because in the off season, I’m always interested in gaining more lean body mass and prior to competition I have to make a weight class (middleweight has a 176 1/4 lbs cutoff. )

I’m 5’ 8” tall and I weigh 174-176 for competitions. That is very much a “false” weight, however, because I easily lose 6-10 pounds of water weight in the three days before a contest. By the Monday after a Saturday contest, my weight is usually back up to 180-184 or so. Off season, I weigh about 195-200 lbs. My off season body fat is usually around 9-10% and before contests it’s around 4%.

Years ago I do remember measuring my arms and they were 17 1/2” cold and 18” pumped. That was a long time ago. I would imagine they’re bit larger now, but who knows. My waist is 31-32” most of the year, even smaller before contests (last notch on the lifting belt!)

These are somewhat typical off season / pre contest height, weight and body fat measurements for a natural bodybuilder. In the professional and open federations (not drug tested), those weights and measurements might be considered “small.” However, a 17-18 inch arm on a lean and proportionate body can look very impressive.

Steve Reeves for example, was known as one of the most symmetrical and aesthetically pleasing bodybuilders of all time, even though he was not “huge” by today’s standards.

Reeves wrote about ideal measurements frequently and was always striving for his idea of perfection in this regard (and came close to achieving his own personal ideal). One of his criteria for ideal proportions included having his arms, calves and neck measure the same.

Steve Reeves Measurements:
Arms: 18.5 inches
Calves: 18.5 inches
Neck: 18.5 inches
Thighs: 27 inches
Chest: 54 inches
Waist: 30 inches

In his “classic physique” book, Reeves said his formula for “ideal proportions” was as follows:

Muscle to bone ratios:
Arm size= 252% of wrist size
Calf size= 192% of ankle size
Neck Size= 79% of head size
Chest Size= 148% of pelvis size
Waist size= 86% of pelvis size
Thigh size= 175% of knee size

Steve Reeves’ height and weight chart for a bodybuilder (natural)
5’5” 160lbs
5’6” 165lbs
5’7” 170lbs
5’8” 175lbs
5’9” 180lbs
5’10” 185lbs
5’11” 190lbs
6’0” 200lbs
6’1” 210lbs
6’2” 220lbs
6’3” 230lbs
6’4” 240lbs
6’5” 250lbs

In the book Brawn, Stuart McRobert published the old “John McCallum formula for “challenging yet realistic” measurements for “hard gainers. His formula is based on wrist measurement and was also published in the book Super Squats:

John McCallum’s realistic measurement ideals for hard gainers
1. 6.5 times your wrist gives chest girth
2. 85% of the chest girth produces the hips
3. Take 70% of the chest girth for the waist
4. 53% of the chest gives the thigh girth
5. The neck size is 37% of the chest
6. 36% of the chest produces the upper arm girth
7. The calves come out a little less at 34%
8. The forearms get 29% of the chest measurement

Incidentally, McRobert’s book Brawn has an entire chapter called “expectations” which discusses the truth about measurement claims.

I find all these measurement ideals very interesting, but personally I take them with a grain of salt.

Be careful with some of the formulas for “ideal measurements”, because if they were based on steroid using and or pro bodybuilders, you may get discouraged by trying to pursue an impossible goal for a natural bodybuilder or the measurements of someone with a totally different bone structure than you have.

Measurements – especially arm measurements – are also frequently exaggerated. Twenty inch arms, for example, are rare and when you actually see them in person, you realize just how massive they really are. But somehow beginners and natural athletes get the idea in their head that bodybuilding success means 250 pounds and a 20 inch arm.

The truth is, a 17 to 18 inch arm on a ripped 175-180 pound physique with excellent balance, symmetry and proportion can look much larger than it really is – it’s an optical illusion of sorts.

Some of these guidelines for “ideal proportions” are the “Grecian” or “classical” ideals while others are ideals for bodybuilders. In either case, keep in mind they are subjective – they’re just someone else’s opinion of what is an ideal measurement. The only opinion that matters in the end is your own.
