Your body is going to answer differently than you. If you have tried several times to lose weight, and it doesn’t seem to work as well as before, you might have a problem that you don’t know about.

Have you ever heard of hibernation mode? When a bear stores up fat for the winter, his body goes into a hibernation mode. It stops burning that fat at the normal rate. The bear’s metabolism says,”Hey, remember the last time when the food stopped coming for a couple months? It looks like that’s going to happen again. If there is going to be a food shortage for the next couple months, I won’t burn the calories.” The bear has a built-in system for not losing weight based on the food supply called the hibernation mode.

So do you.

This is a physiological instinct. It is as natural in your own body, or the bear’s, as a heartbeat. You can’t dictate to it or control it any more than you can make your heart change rhythm. Here is what happens in a person: When you decide to go on a diet for the very first time, your body doesn’t realize that this will be a temporary suspension of intake, so it just keeps on burning the calories at the normal rate which leads to a great weight loss. You slim right down, and everything is terrific. That happens the first time.

The problem is, and I’m sure you will recognize it, that as you lose whatever weight you wanted to take off and are very happy with the results, your body is asking what happened to the food supply. It starts to say “When the food comes back I’m going to have to store some of it, just in case this happens again.”

You are happy with your weight loss and go off your diet. You go back to the same eating and exercise habits that led to the diet in the first place. You aren’t aware that your body is making plans to keep some extra fat for the future.

Then, after a while you look in the mirror and realize you put all the weight back on. You go back to that great diet that helped you lose all that weight, but something different happens this time: the weight doesn’t melt off.

Why? Your body has activated its hibernation mode. Your body recognizes that the food supply has just shut down so it takes an animal instinct function of “winterizing” the metabolism. When there’s no food coming in it must be hibernation time! I won’t burn the calories.

That is not a choice that you consciously make, it’s an animal reaction. Your body’s physiology accepts the food cutoff and responds to it. The diet takes longer and longer to get the job done, but eventually you reach your goal weight, and go off the diet and back to your old ways. You start piling on the pounds faster now, because your body, again, is making a survival decision: fatten up, because there will be more of these winter periods, and they may get a lot longer. You get into the well known “yo-yo” pattern: put a little on and fight to get it off, then put more on, then take that off, and over and over and over.

This is the whole problem. As you go on a diet for a fix for your weight situation, you have to be aware that part of your brain is not going to co-operate. Your brain won’t let you lose weight time after time on the same plan.

Bottom line: Weight loss isn’t about a short term change in your food intake. True weight loss is about long term change in your eating habits. If you eat too much for your body to burn, you will get fat. Worse, if you eat and stop eating time after time your body will store fat from every meal. If your body sees the food supply shutting down it will tell your metabolism to burn calories more slowly, so you may only use 1500 calories the next day instead of 2500. Instead of losing weight, because your body doesn’t want to let you starve, you may go on a diet and gain weight.

The fact is the only way you can truly control your weight is to study your own habits that are leading to weight gain and change them. Those would be food intake, diet, and exercise. Yes, exercise! And you can’t go to the gym and work out, and then stop on the way home for an ice cream. Your mind is thinking about losing weight, but your body is saying that you deserve the ice cream for having worked out, but actually is trying to trick you into adding more calories so it can keep itself going.
