Chronic dieting (people I know that went crazy) slows down your metabolism because your body thinks you’re in a perpetual famine.
When you eat too little calorie, carbs or fats for too long your body never gets enough calories, carbs or fats to tell it that times are plentiful and you don’t need to hold onto stored fat.
So if you want to speed up your thyroid and metabolism you have to start giving your body more not less. You need to change the signals your brain is getting from ‘scarcity’ to ‘plenty’.
So when your metabolism is lower, you need both lower calorie intake and more activity to burn calories in order to maintain your current body weight or lose weight, Which can make losing weight extremely difficult.
Calorie restriction and body fat loss also leads to drops in leptin, a hormone that suppresses appetite; and ghrelin, which boosts appetite.
Regular cheat meals: Incorporating cheat meals into a nutrition plan can also have positive mental effects during a time when many might feel fatigued from often monotonous diet plans…. A better name is ‘relaxed meal.’
“A cheat meal can usually fit in once every week or every two weeks depending on the person’s metabolism, genetics and muscle mass,”
