How does yo-yo dieting mess up our metabolism?
People say after dieting on and off its harder to lose weight. Why is that?
Yoyo dieting is bad over all but it also stresses your metabolism. Since you diet a certain way for a long period of time (your regular habits), your body is used to the way you do things. Your body is aware of when and how much you usually eat etc. so it digests accordingly.
When you starve your self all of a sudden for awhile, your body uses up all your stored energy and digests slowly so that you will not run empty. So by changing your diet so dramatically and suddenly, you force your body to go into emergency mode basically.
After your period of starvation, you are bound to eat again, but even if it is VERY little, your body will be like "oh my god! food, what do I do?" but by then, your metabolism would’ve gotten used to being that certain way. It’s like going from 100 to -1, it’s very difficult, if possible, to get your body back into a healthy state. Even though you might loose those pounds after a hard week of eating next to nothing, you are bound to gain some back, then it would be very difficult to use a proper healthy diet to change your body.
Dangers of yoyo dieting: your body resorts to consuming energy and nutrients from your muscles, which will leave you will decreased mobility. people who go on crash diets have higher chances of going blind, getting arthritis and diabetes. and plus, why would you always want to look tired?
Your body has memory of starvation episodes so when you go into a new diet it respond by lowering its metabolism.
If you are putting and losing weight often, your body will not respond anymore and it will live on the minimum.
The only way to really lose weight is to have the same dieting way for a long term.
Reducing your fat intake will make your body use its own fat and reduce atherosclerosis risk.
The low-fat diet For: MILD OVERWEIGHTS
If you are only mildly overweight (5 to 15 per cent above your normal weight; let us say you are 7 to 20 lbs. over.) then follow the 1200 calorie diet described in the center, green section.
After you have lost an average of 2 lbs. each week and have achieved your normal weight, you should then follow the low-fat maintenance diets. These diets range from approximately 1500 calories to 2200 calories. They are recommended for the average individual who does light work with a moderate expenditure of calories in average daily activi¬ties.
Maintaining your proper weight by a regular calorie count. However, since individuals vary so widely, it is impera¬tive that you watch your weight carefully by your household scale. If you find that you are gaining a little or a moderate amount of poundage (say 1 or 2 lbs. each week) then you must subtract 200 to 500 calories from your daily menus. You can then reduce a pound a week and stay on this "maintenance" diet to keep your weight on an even leve

Yo-Yo dieting mimics the cycles of feast & famine our ancestors use to suffer.
You ate in times of plenty, good harvest & hunting, but when times were tough, drought & poor hunting, your body had to store fat & energy for the lean times.
When you starve yourself to lose weight, your body says, oops, lean times ahead, I need to hold on to my weight.
They you start to eat normally again, you body says great food, we need to store up fat for the next lean time.
You body fights you every step of the way. Forget the scale, work for fitness & strength.
