9 More Reasons You’re Not Losing Weight

Posted by Mark Sisson

4. You’re under “hidden stress"

In the previous article, I explained how stress can make us gain weight, or stop losing it. Cortisol – which we release as a part of the stress response – inhibits weight loss, catabolizes muscle, worsens insulin resistance, and promotes the storage of fat. Although back then I was referring to the obvious sources of stress in our lives, like bills, traffic, jobs we hate, bosses we hate, relationship strife, there are other “hidden” types of stressors that result in the very same physiological responses as obvious stressors cause. Foremost among the hidden stressors is the lack of nature exposure. In the literature, researchers often speak of “forest bathing,” or spending a day or two or three in a forest setting to reduce cortisol, enhance immune function, and improve glucose tolerance. I prefer to look at this a different way. Instead of nature exposure being a positive anti-stress agent, urban living is an active stressor. Spending a day in the woods is a return to normalcy rather than an “intervention.”



If you’re not doing this already, take a day or two out of the week to get outside, preferably amongst unkempt, wild nature. It needn’t be a forest or a craggy cliff. The beach, the desert, or even a park will do just fine. In a pinch, you can even listen to nature sounds and look at nature scenes on your computer.

5. You’re too focused on diet to the exclusion of all else.

When you realize the wool that’s been pulled over the collective eyes of society regarding nutrition, it’s easy to become obsessed with your newfound knowledge. It’s easy to stay up late, night in, night out, perusing nutrition blogs, reading comment sections, devouring PubMed articles. You’ll hear about some arcane but totally essential nutrient and think that it’s the Answer. Am I getting enough magnesium? What about boron – I need some boron, right? How about vitamin A? Should I go for the preformed retinol or rely on the conversion from beta-carotene? Should I drive fifty miles out of town to get goose liver, or should I just take a vitamin K2 supplement and call it a day? Choline – that’s the stuff! Nothing but liver and egg yolks from here on out!

Diet is the obvious primary arbiter of body composition, but there’s more to life than worrying about what you put in your mouth. It’s counterintuitive, and there aren’t any randomized controlled trials showing it, but you might have more success just enjoying life, getting some exercise, and hanging out with good people instead of micromanaging your nutrient intake. Relax.

6. You’re getting too much exercise.

Although regular exercise is a necessary component of a healthy lifestyle, and smart training that includes lifting heavy things, walking lots, and sprinting occasionally can speed weight loss and improve body composition, there is such a thing as too much exercise. After all, effective exercise is effective because it’s stressful, because it challenges our physiology and propels us to rise to the occasion and improve ourselves by getting stronger, faster, and with more lean mass and less body fat. Taken to the extreme, exercise becomes a chronic stressor and a steady source of cortisol release (which as we discussed above makes us insulin resistant and promotes the accumulation of belly fat). Chronic stress in any form can also induce a hypothyroid-like state, where metabolic rate is lowered and weight loss slows or stops altogether, and exercise-induced chronic stress is no different.

Try to stick to the 4,000 calories a week (soft) limit, especially if you find your weight loss stalling.

7. Your macronutrients and training are mismatched.

For most people who stay reasonably active, doing lots of low-level movement as well as some lifting, a low-carb Primal way of eating is generally the most effective way to lose body fat. It tastes good, it’s easy to stick to, and, most importantly, it works. But some people like to push the envelope. They like waking up early and going for a run, then coming home at night and hitting the weights. They’re avid CrossFitters. They like seeing how far their bodies can go. They’re concerned with performance, above all else, and they want to maximize every last drop of physicality their bodies can muster. In that case, more dietary carbs are probably called for – especially if they’re trying to lose weight at the same time. Certain activities just require glycogen. I do plenty of activities that use up glycogen, but I’m not doing them day in, day out, so I don’t need to eat a lot of carbs.

If you are, if you’re doing WODs every day and playing in a basketball league on the weekends and doing jiujitsu twice a week, you’ll need to replenish those glycogen stores more often or else risk that chronically-stressed state that stops weight loss.

8. Your eating schedule is too disordered.

I tend to get hungry at different times throughout the day, and I have no issues eating meals at different intervals depending on when hunger strikes. That seems to be pretty typical. Although many Primal eaters relish the freedom from having to keep snacks on hand in order to stave off hunger and enjoy the fact that they can skip a meal or two and just rely on their hunger signals, there is a considerable amount of evidence that maintaining a regular eating schedule can improve the metabolic response to meals in some people. Women in particular seem to benefit most from a “regular meal pattern.” In one study of lean women, an “irregular” meal pattern resulted in lower postprandial energy expenditure than a regular meal pattern. In another study, lean women who ate meals on a regular schedule had better insulin sensitivity and improved blood lipids. And in one other study of healthy obese women, regular mealtimes increased postprandial thermogenesis, insulin sensitivity, and blood lipids.

Sometimes, you might need a little order to your eating, whether you’re IFing or not. And that’s totally fine.

9. You’re actually at a healthy weight and your body is “keeping” you from dropping any more.

I know, I know: your body is a huge jerk and he says mean things to you. But sometimes the body knows best. Sometimes, our current body composition is where we’re supposed to be, even if we only have a four or a two-pack (or none at all). Recall the natural bodybuilder who, upon dropping from 14.8% body fat to 4.5%, also dropped his metabolic rate, his body temperature, his heart rate, his testosterone levels, and his moodiness. Recall that women deposit fat differently than men and actually need some body fat for optimum fertility and health. Instead of obsessing over a few more percentage points on the body fat scale, think about how good you’re feeling, how your health issues have cleared up, and how you enjoy movement more. And if you want to alter your body composition, focus on addition – lifting heavy things, sprinting – rather than subtraction. You might be right where you’re supposed to be.

One final point: Note that I’m not saying eating too few calories or exercising too much or focusing too much on diet to the exclusion of all else will make you gain weight. I’m saying that it can lead to or exacerbate a stall in your weight loss. It’s a small distinction, but an important one.
