5 foods to avoid before a workout

5 foods to avoid before a workout

Fuelling up before a serious workout is always wise so you don’t crash and burn too soon, but be careful what you put in your body or you’ll end up doing more harm than good.

Here are some foods to avoid before you tie up your trainers:

Legumes

Although high in protein, beans, hummus and lentils can cause unwanted side effects during your workout such as bloating and indigestion.

Protein Bars

Unless they are moderate to high carb bars, you’ll probably find that they won’t fuel your workout effectively. You need high energy levels to stop you crashing during a workout and these bars just don’t cut it.

Carbonated Drinks

Excessive sugar in these drinks can have unwanted effects. The spike in your blood sugar can lead to a crash later on, and can even leave you with bloating or diarrhoea – side effects that you really don’t want to have mid-workout!

Simple Sugars

Packets of sweets, chocolates, cereals, biscuits – all these high sugar foods can cause reactive hypoglycaemia – when a sudden drop in blood glucose levels takes place after a huge peak in blood sugar. This can leave you tired, with headaches and overall poor performance.

Cheese or Peanut Butter

Although a good balanced diets should include fats such as these, they are extremely slow to burn off and can slow the absorption of nutrients making them not so ideal to consume before a workout. It’s far better to combine both protein and carbs.

I love a good solid peanut butter and cheese sandwich - but it is far too hefty to eat before a workout. Training fasted isn't just for more efficiency, it avoids a stomach ache!

How long before a workout should you avoid these? I might have a protein bar at 4pm, then workout at 5. It's never bothered me but now I am wondered if I should swap it for something else.

I often have a peanut butter and banana sandwich after a workout - had it once before a workout and got a stitch, so have never done it since!

I like the delicate phrasing as to why you shouldn't turn up to a workout with a stomach full of legumes...let's just say there are antisocial reasons too!

When I was younger I remember being told my a PE teacher to eat jelly babies before sport for their sugar rush. I have never forgotten this and still do it sometimes. It does give me a boost! I guess the advice has sadly changed.
