Crash Diet or Healthy Eating?

Healthy eating is always best but what about a crash diet?

Crash diets are a great way to lose weight quickly – so long as you’re responsible about it. But, there are a couple of things you need to consider about the crash diet before throwing yourself in at the deep end.

They come in many shapes and forms – salad diets, liquid diets etc. but, the principle is always the same: extremely low-calorie consumption (below 1,000kcal per day).

You should take note that with crash diets, more often than not, you crash – you feel lethargic, tired, irritable and low.

Needless to say, you should not partake in crash diets for any longer than 2 weeks, to avoid major detriment to your health.

Possible bad side-effects

You should take caution when crash dieting as you will notice symptoms like:

  • Tiredness & fatigue
  • low moods
  • irritability
  • poor complexion
  • pale skin
  • upset stomach
  • hunger (sometimes extreme)
  • lack of concentration
  • lack of energy

Questions to ask before Crash Dieting

If you’re really considering it, you’re going to have to think about what you want to achieve. Questions like this will help you decide:

  • Is health or weight more important?
    If your losing weight to return to full health, a crash diet probably isn’t the wisest idea.
  • Is there a deadline?
    If you’re working to a deadline and it’s quickly approaching, it might be worth considering a crash diet.
  • Why do you want to lose weight?
    If you are losing weight to look great for a holiday or ‘just because’ – you might be better eating healthily and keeping up with your exercise regime.
  • Do you need to preserve muscle?
    If you’re working towards a photo shoot or a bodybuilding/strength competition, you shouldn’t crash diet. You’re going to lose your gains and your strength.
  • What’s your job – manual labour or an office job?
    If you work an office job with little activity, it is possible to work and go through a crash diet. If your job requires some physical activity, you may have to reconsider.
  • Do you exercise a lot?
    If you’re doing a crash diet, your exercise regime is going to suffer – you won’t be able to keep up with your usual activity levels.

Still, want to crash diet?

Personally, I don’t mind a crash diet for a (quiet) week because I know my diet is varied enough and I lead a healthy lifestyle. But I would never make a habit of it.

Are you going to go through all of these bad side effects for the sake of some extra weight you want shifting? Or is it better to consider improving your health by eating a wide range of natural, minimally processed foods?

Before proceeding with a crash diet, please consult your doctor or general physician for advice and guidance.
