The human body seems to easily adapt to changes in our lives, and the reason for this is simply down to survival. The fact is our body must adapt in order to stand any chance of surviving sudden changes to the environment. What many dieters don’t realize is that our body also adapts to changes in our eating habits, both overeating and under eating causes the body to adjust.
The reason why we adapt to changes in eating is again for survival reasons. For example, if we struggled to find food our metabolism gradually lowers so we no longer require as much energy for growth and maintenance. The result is we can still survive on low food intakes.
Calories don’t add up
The basic adaptations above mean that after a weight gain if you continued to consume the same number of calories then gains in weight will slow. For example, if you require 2000 calories per day to maintain body weight but you eat 3000 calories for years you will obviously gain weight. However most of the gain will be within the first few months and eventually it will stop. It stops because the physiological changes help balance the energy in with energy out, thus soon your body will require 3000 calories per day to maintain that heavier weight. Make sure you consume a bit less calories than your body needs.
The reason why people keep gaining further weight year after year is usually because they either consume even more calories or they become progressively less active, or both. In other words, as one pound is gained it requires even more excess calories to gain another pound. Scientists believe this is a natural adaptation we have to help maintain a steady body weight.
These facts are the reason why calories don’t seem to add up when trying to lose a certain amount of weight. For instance there are 3500 calories in one pound of body fat, so if you were to cut daily calorie intake by 500 then theoretically you should lose one pound of fat over a week. However if you continue you’ll find that weight loss slows then eventually stops, you reach a weightloss plateau. This is because eventually the low calorie energy intake balances with our energy output, thus there is no longer an energy deficit.
How to lose fat weight
As the human body can adapt so well to changes in food intake there needs to be a regular adjustment to the diet when attempting to lose weight. The obvious thing to remember is never severely cut food intake in order to lose weight as this will lead to a huge loss of lean muscle as the body adapts, instead lower calorie intake a little each week. This will give the body time to burn some stored fat without the negative effect of losing too much lean muscle. By saving as much lean muscle as possible you’ll keep the metabolism sufficiently high enough to maintain continuous fat loss for several months. Sport will also help you to keep your metabolism high and burn body fat.
