So, You Think You Can Keep The Weight Off After Doing Kimkins Starvation Diet, eh?
This is a difficult post for me to write, I’ll say that at the outset and get it over with. I hate to post such a personal account, but this needs to be said, to serve as a warning to anyone trying to lose weight by cutting calories too low.
I lost almost 40 lbs in 2006 by carefully counting my carbs, while also keeping my fat intake at a moderate level. Was I doing Kimkins?
No.
However, I was definitely influenced by Heidi Diaz’s low-fat, low-cal propaganda.
Like those doing Kimkins, I ate lean protein, such as water packed tuna, boneless, skinless chicken breasts, and turkey breast. I also ate boneless pork loin, with as much fat trimmed off as possible, which makes it a fairly lean protein, along with whole eggs, some cheese, and nuts, which gave me a total daily protein consumption of approximately 65-90 g protein.
I ate 20-40 g of net carbs daily (deducting fiber only), primarily in the form of salad greens and other very low carb veggies, such as green beans, spinach, cauliflower, broccoli, and zuchinni, but there were also occasional incidental carbs from condiments such as mustard, mayo, and vinegar, as well as various herbs and spices. Of course, I also counted the carbs from cheeses and nuts.
I cooked the meats and eggs in small amounts of fats (usually 2 tsp or less per serving, depending on the particular recipe I was using), but did not butter my veggies, or add butter to anything at the table. I did however use full fat mayo and salad dressings, which along with the cheese and nuts is one of the few things that distinguishes my eating from Kimkins.
I exercised 5 days/week for at least 90 minutes each day, with approximately 2/3 of my time spent in aerobic activity, and 1/3 on weight resistance machines.
My calories were averaging around 1400 each day.
However, my Basal Metabolic Rate (BMR) during this weight loss period began at nearly 1750 calories/day. When I reached my lowest weight, my BMR was still well over 1500 calories/day. Add in my workout calorie expenditure, and my Active Metabolic Rate (AMR) started out at more than 2700 calories. Even when I reached my lowest weight, my AMR was still over 2400 calories/day.
One would think that because my calories were below my BMR and still so far below my AMR, I would have continued to lose weight, right?
Wrong!
Through most of 2007, I barely maintained my weight, still eating the same average 1400 calories/day, still maintaining the same exercise schedule.
Towards the end of 2007, the cravings started. Not for high carb foods. I had no desire to dive head-first into the tortilla chips and mashed potatoes - I just wanted more food in general. More low carb veggies, more cheese, more meats, nuts, and fats of all kinds. Because I was eating more veggies, nuts, and cheese, I was admittedly eating more carbs - approximately 30-50 net per day. And because of the increase in fats, I was also admittedly eating more calories too, somewhere in the range of 2000 calories on a daily basis.
Even eating like that, logically I should certainly have still been able to continue to maintain my weight loss, or even continue to lose weight. I was still eating at a low carb maintenance level, even if I wasn’t keeping my carbs low enough to be in ketosis. The main thing is that I was still more than 400 calories per day under my AMR for my lowest weight, which should have still resulted in a loss of slightly less than 1 lb per week. Right?
Wrong again!
When the cravings began, I started gaining weight. Not just a little weight, either. I began gaining it at a dramatic rate, for a total gain of more than 30 lbs in about 6 months.
When I started gaining weight, I began blaming myself for having so little self control, and for eating entirely too much food.
So I tried cutting back again. I was drinking more water, eating sugar free jello for snacks (not the commercial kinds with the aspartame in it - I made my own nearly-calorie-free jello, using unsweetened kool-aid, unflavored knox gelatin, and stevia, so no hidden carbs, and no artificial sweeteners to stall my efforts) - just anything to stave off snacking, or eating larger meals, and more real, calorie-laden foods. The 1400 Low carb calories had worked before, so I tried to get back to it.
Even cutting back a little bit should have certainly stopped the weight gain in it’s tracks, right?
Wrong yet again!
I couldn’t stay at that 1400 calorie level. The cravings for more food were too strong, so I kept bumping it back up to around 2000 calories.
I continued to gain weight, to the point where as of a couple months ago, I had re-gained nearly every pound lost in 2006
What went wrong?!
Coincidentally, during the period of weight gain, I learned about BMR, and how our bodies conserve calories when we go below our BMR for an extended length of time.
Basically, the problem was that I was eating below my BMR the entire time I was losing weight. When you do that, your body thinks that food is in short supply, and conserves every calorie it can get. No matter how hard you exercise, your body simply becomes more thrifty with the calories you consume. You could cut calories even more, or exercise even more, and perhaps lose a little more weight, but your body simply recognizes the calorie restriction as a more dangerous famine state and revs up it’s efforts to become even more efficient at conserving energy. If you continue in the cycle of further cutting calories every time weight loss stops, your body will simply become more and more efficient at conserving calories.
Starvation mode really does exist.
I was therefore destroying my metabolism, by eating at semi-starvation calorie levels for so long. Yes, it can happen even at what looks like “normal” calorie levels for a normal sized woman, if your calorie intake is below your BMR for any length of time.
When the cravings caused me to begin upping my calories, my body responded by replenishing it’s fat stores, just in case another famine cycle would hit, hence the dramatic weight gain.
Kimkins dieters, beware of the Wrong you’re doing to your body!
Kimkins members regularly consume 800 calories or less, while their BMR could be anywhere from 1400 to well above 2000 calories per day. That means they’re consuming 600 to 1200 calories below their BMR.
Remember that the BMR is the number of calories your body needs to function at it’s most basic level - the number of calories you would need to keep your organs functioning, if all you did was lie in bed 24-7. If you go below this level of calorie intake, your metabolism will slow, in an effort to avoid catabolizing lean tissue (muscle, organs) to support basic function. Go significantly below the BMR, and your body will have no choice but to catabolize lean tissues to support basic function.
I had these weight regain problems after a period of going only a maximum of 350 calories below my BMR. When I stopped losing weight, I was still staying only 100 calories below my BMR.
That doesn’t sound like much of a difference, does it?
It’s not.
But it gives you an idea of just how sensitive the body’s metabolism is to regularly consuming fewer calories than it needs to maintain basic body function.
If you’re doing Kimkins and are regularly eating 600 or 1200 calories below your BMR, the damage to your metabolism will be even more dramatic.
The weight regain when going off Kimkins will also be even more dramatic than what I experienced, because not only will your metabolism be trashed from the extremely low calorie levels, the body will be so starved for much needed nutrients that your calorie consumption will probably skyrocket to a point well above your AMR.
Remember, there is not now, nor has there ever been a maintenance program on Kimkins. Even maintaining your weight while continuing to starve yourself at Kimkins calorie levels will become increasingly difficult, as your body learns to conserve calories more efficiently.
There is Hope for Righting the Wrong!
As I continued gaining weight for several months, both my BMR and AMR were also increasing, to the point of my AMR being as much as 700 calories higher than my daily calorie intake.
However, this bit of information is an important detail: My weight has now leveled off, in spite of continuing to eat the same approximately 2000 calories per day, which is the same calorie intake as when I was still gaining weight - but remember that both my BMR and AMR have continued to increase also, so it’s not simply a matter of eating up to my maintenance level.
What happens is that after eating at least as much as your body really needs to maintain itself for an extended period of time, your body will finally decide that it’s no longer in immediate danger of starvation. It will cease to conserve every possible calorie as fat. Your metabolism will eventually heal - but only if you give it what it needs, for a long enough period of time so that it can heal.
If you are currently doing any Kimkins plan, please quit now, before you damage your metabolism further.
If you are looking for a healthy diet plan to start losing weight, or to heal your metabolism after a period of eating below your BMR, so that you can begin to lose in a healthy way, I personally would suggest Atkins, Protein Power or South Beach.
