Intermittent Fasting vs. Caloric Reduction – What’s the Difference?

Is there any difference between fasting and caloric reduction?

Some would argue that the beneficial effect of fasting is entirely due to the caloric reduction. If true, then why is there such a striking difference between stunning failure of chronically reducing calories and stunning success of fasting?

Caloric Reduction as Primary (CRaP) has been tried innumerable times over the past few decades, and failed virtually every single time. Yet fasting is often effective where simple caloric reduction is not. Why? Continue Reading →

Intermittent fasting – a great weight-loss method

Have you made a New Year’s resolution to lose weight? We’ll repeat our best weight-loss tips during the beginning of the year. Like this:

Intermittent fasting is a very effective weight-loss method. It causes insulin, the fat storing hormone, to hit rock bottom while fat burning drastically increases.

So how do you get started? There are many methods you can try. One common way is skipping breakfast and perhaps even lunch – that means that you’re in a fasted state for 16 to 24 hours.

New Study: Breakfast is Very Overrated



We’ve all heard it: Breakfast is “the most important meal of the day”. Especially if you want to lose weight, you should make sure you eat breakfast. This is a belief that is supported by about zero hard science, and it makes just about no sense at all. Why would anyone lose weight by making sure they eat more?

A new high-quality (RCT) study tested the concept. Forty-nine women who did not usually eat breakfast were randomized to one of two groups: keep skipping breakfast, or start eating it. They were then followed for four weeks to see what happened.

According to conventional wisdom the people who started to eat breakfast would miraculously start losing weight and feeling great. But that’s not what the study found.

The women who started to eat breakfast…

  1. Ate more food in total over the day
  2. Ate more carbs in total
  3. Finally, not surprisingly, they gained weight

Nobody should be surprised. Feel free to eat breakfast if you’re hungry and it makes you feel good. But there’s no need to eat breakfast, and it’s certainly not going to help you lose weight.

It’s perfectly OK to break your fast (“break fast”) by eating lunch instead… Continue Reading →


Fasting and Hunger


Does fasting increase your hunger to unimaginable and uncontrollable dimensions? This is often how fasting is portrayed, but is it really true? From a purely practical standpoint, it is not.

They often say things like, “I thought I would be consumed by hunger, but now I only eat a third of what I used to, because I am full!” That’s great, because now you are working with your body’s hunger signalling to lose weight instead of constantly fighting it.
