A calorie is a calorie.

People always come to me saying that they cannot lose weight, that they have tried everything from exercise to diet but still can´t get rid of those extra kilos. They say that they have  a ¨slow metabolism¨ or some other excuse and they are basically lying ( click here). Lying to themselves and to the  people around them because, listen closely I´m going to tell a secret, to lose weight you have to eat less and move more. Yes, that´s right, eat less and move more, don´t believe me, look at the studies (1-4).

People don´t understand but you can actually lose weight eating ¨junk food¨ as long as you are in a calorie deficit. You see, there is no evidence that junk food is more fattening that healthy food if both foods have the same number of calories (5) because a calorie is a calorie.  Well ok, consuming  proteins causes a greater energy expenditure than consuming fat or carbohydrates (6), but still for the sake of simplicity a CALORIE is A CALORIE. If you want to lose weight create a calorie deficit, meaning burn more than what you are eating. And that is exactly what John Cisca did a couple of months ago. He lost 37 pounds in 90 days eating just McDonald’s, it´s a true story (click here). And how did he do it, you ask?? That´s right – by creating a calorie deficit.

Even after explaining this to people you will still hear (at least I do), that ¨I exercised and  I ate less and still I didn´t lose weight¨. So what do you do with these people? First, you tell that in almost 100 years of weight loss research, there hasn´t been a single human that didn´t lose weight when they were in a caloric deficit, so they probably aren´t the exception. Second, you explain to them that people are horrible at counting calories and most of the time eat more than what they think (excellent video – you have to watch  both parts) and also move less (burn less calories) . If they still don´t believe you (which some actually won´t), smile and walk again.

Now there are some exceptions to this rule,people who have a thyroid problem will have a problem losing weight(7) and also some medication can hinder weight loss;

  1. Paxil- used for anxiety
  2. Depakote- used to treat bipolar disease
  3. Prozac- It is associated with weight loss in the first 6 months but after it causes the opposite effect. It´s used for depression
  4. Remeron- Anti-depressant
  5. Zyprexa- used for bipolar disease
  6. Allegra-Zyrtec
  7. Deltasone- Treats asthma and inflammatory bowel disease
  8. Thorazine
  9. Elavil- Anti-depressant
  10. Diabines, Insulate- Type 2 diabetes drugs
  11. Insulin- stops protein breakdown.
  12. Tenomin- Beta-bolcers, drugs used for high blood pressure

* if you are on a medication NEVER stop unless you have talked to your doctor first.
