One of the most important aspects of losing weight and slimming is to avoid hunger. For too long, dieting has been associated with deprivation, the need for extreme will power and constant cravings and hunger. Most cravings are merely hunger.
Classically, people will switch to eating salads (which are mostly just water - not unhealthy, but hardly very filling), eat much smaller portions and will tend to miss meals.
Don't miss meals. This is crazy behaviour.
When you miss a meal or allow yourself to go hungry, the body has an adaptation response to this. It releases hormones that create a significant change in the way the body processes calories - it stores them as fat.
So, as you starve yourself, your body starts preparing to lay down more fat quickly, so that when it faces the next virtual famine, it has enough energy stores to get by with. With the semi-starvation approach, we will see rapid weight loss, followed by rapid weight gain.
The other problem with going hungry is that you will tend to make bad food choices.
Hungry people crave high-calorie foods with high flavours. These foods will also tend to be of an instant type of food, as immediacy is also sought.
Eating regularly will help avoid these problems.
Next time you have a craving, ask yourself - is this a genuine craving or are you just hungry?
