Some of the most common reasons why you can't lose weight are cited hereunder:
1. You cannot calculate -even roughly-the calories you consume. You severely underestimate them:
-you eat bigger portions than what you are supposed to
-you eat a lot of snacks while ignoring their caloric contribution
-you ignore the caloric value of many foods.You cannot even imagine that a cookie might have about 200 calories so why not eat 5-10 of them after a workout of 300 cal?
-you consume a lot of liquid calories that escape your control.Things like:
*smoothies
*refreshments
*milk shakes
*juices
*glamorous coffees
*energy and sport drinks
*alcoholic beverages
*cocoa milk etc
add many hidden calories.
2. You overestimate the calories burned via various activities.Some people burn 300-400 cal. and then they consume 1000 cal to replace the lost glycogen.
There are people who exercise every day but struggle with obesity on a continuous basis.
3. You do not know how to calculate your maintenance caloric intake.You often overestimate it.
4 You do not get adequate sleep.As a result your ghrelin and stress hormones are elevated and you feel more hungry.
5. You are under constant stress.As above ,your stress hormones-cortisol,adrenaline etc-will reach high levels together with your feeling of hunger.
6. Maybe your metabolism is impaired due to hypothyroidism or other cause.
7. You cannot control emotional eating.You use the food to feed your emotions and not your body.Learn to distinguish between them.
8. If you take drugs like steroids or antihistaminic, it will be difficult to control your apettite.
9.If you avoid breakfast it will be a daunting task to lose weight.The same is valid when most of the calories are consumed later in the day.
10. When you eat few and big meals it's more difficult to lose weight.Try instead to eat lighter meals more frequently .
11.Whatever you do you are not going to lose weight if you consume a lot of simple,proccessed carbs.Minimize their consumption and you will increase your odds a lot.
