Sustainable weight management is possible and understanding how your body responds to weight loss efforts can help you establish realistic expectations on your journey.
Here are 8 things you may not know about your body and weight loss.
1. Your Metabolism Will Slow Down to Store Fat
The more you work out or manage your calorie intake to lose weight, the more your metabolism wants to compensate by slowing down to maintain your current weight, this is called metabolic compensation. It kicks in to preserve and store fat for future energy. Research shows that this happens because the human body has evolved to value storing fat and energy and to interpret a shortage of calories as sign of distress.
2. Your Hormones Will Increase Your Drive to Eat
Metabolic compensation isn’t the only way that your body’s can prevent weight loss or encourage weight gain. Fat cells produce leptin, which tells your brain when you’re full. Fat cells shrink when you lose weight, producing less leptin, which means that you don’t feel as full.
Your stomach produces ghrelin, which tells your brain when it’s time to refuel. When you lose weight, your ghrelin levels rise, making you want to eat more often.
3. Weight Loss Impacts Your Brain
When you lose weight, the part of your brain that regulates food restraint becomes less active – meaning that while you’re eating more to feel full (courtesy of leptin), you’re also less aware of how much you’re eating.
4. Your Genes Play a Role
More than 400 genes have been linked to obesity and weight gain, and they can affect appetite, metabolism, cravings and body-fat distribution. It is unclear how much you can be genetically predisposed to weight gain or obesity, but some genes have been associated with difficulty losing weight even as you increase physical activity or low-calorie diets.
If you have a genetic predisposition for obesity, it is easier to take a proactive stance to weight management. A preventive approach is more effective because you are preventing obesity from occurring in the first place.
5. Your Body Is Extra Prepared for Your Second Try
If you’ve lost weight in the past by exercising or changing your diet and try to use those strategies again to lose weight, your body ndash; mainly hormones and metabolism – will adjust to prevent similar damage and you’ll see fewer weight loss results.
6. Your Weight May Have a Favorite Number
Some scientists think that your body has a set point weight and your metabolism, hormones and brain will adjust to maintain that weight. People may have naturally higher or lower set weights than others; their set points can be impacted by genetics, aging, history of weight loss and hormonal shifts. The theory suggests that your set point weight can rise but rarely lower. It is easier to maintain your set point weight because your body wants to remain at that point – not lose weight.
7. Your Weight Loss Might Not Look Like You Expected
After successful weight loss, your body may look different than you were expecting. Stretch marks and loose skin are common, and many people deal with the emotional effects of coping with a body that doesn’t fit what they pictured
8. Your Emotional Health Is Independent of Your Weight
People often tie happiness and emotional health to weight loss. When they have successfully lost weight but remain dissatisfied with other parts of their life, they can fall into a cycle of dissatisfaction. Guilt at not feeling happy after weight loss can be a factor, as well as the temptation to eat to cope with these feelings. Some people can experience an uncertainty about their next goal is after losing significant amounts of weight.
