Whilst I definitely don't endorse binge drinking, the odd boozy night is inevitable, even for the most serious of athletes. (In fact, studies suggest that athletes are more likely than the general population to drink alcohol to excess...) But, how can you enjoy a few drinks whilst minimising the impact on your waistline?

Before I cover some damage limitation tips, let’s look at some of the reasons why drinking large amounts of alcohol can significantly increase the chance of gaining fat...

Alcohol alters your metabolism

When you consume alcohol your digestive system prioritises its metabolism since you cannot store it and it’s effectively toxic to your body. This preferential treatment slams the breaks on protein, carb and fat metabolism, meaning these nutrients (especially fats) are more likely to end up stored than used as fuel.

Alcohol affects your appetite & choices

One of the better known side effects of alcohol consumption is a loss of inhibition. Combine that with the potential for alcohol to increase appetite and the likely proximity to high-calorie, very palatable food and you have a recipe for disaster for any health-conscious drinker!

It’s not just the decision to indulge in the first place that’s affected but the amount of food we end up eating too. And that preferential metabolism of alcohol in your system means those calories from late night feeds are more likely to end up stored as fat.

Alcohol causes hangovers

Large alcohol intakes impair sleep quality and quantity and also promote dehydration (due to alcohol’s diuretic effect). These factors leave you feeling pretty rough the next day and, consequently, activity levels and energy expenditure can plummet whilst you’re hungover.

Combine this with a tendency to combat hangovers with lots of junk food and the fattening effects of a night out can significantly extend into the following day.

How to minimise the effects of drinking on weight gain

Here are a few tactics to employ to minimize the effects of your next big night out...

Minimize your fat intake

Of the three macronutrients (proteins, carbs and fats), dietary fats are most likely to be stored as new fat tissue when you drink alcohol. Therefore, reducing your fat intake on the day of a night out can lessen alcohol’s fat storing propensity.

Fill up on meals made up of lean protein and veggies

As well as being low in fat, meals high in lean protein and vegetables tend to be inherently low in calories and are great at making us feel full (and thus less likely to graze on unhealthy foods when drinking). This means your calorie intake prior to boozing will be relatively low.

Since your body doesn’t tend to store a great deal of fat unless you consume more calories than you burn, managing your calorie intake through purposefully constructed meals can further limit alcohol-associated fat gain.

Leave a prepared snack or go straight to bed

If you’re the type of person who finds it hard to turn down junk food at the end of the night - either from a fast-food joint or your own fridge - before heading out, try leaving yourself some tasty but healthy food to snack on when you get home.

This would ideally be low in calories, high in protein and veg-based, perhaps some leftovers from your earlier meal. Having this option might make you less likely to opt for junk food when those late cravings kick in.

Alternatively, try getting into the routine of heading straight for bed rather than the kitchen at the end of the night. Though alcohol worsens sleep quality, it does help you fall asleep quicker. So, once you hit the hay you’ll soon be asleep, hunger gone and you’ll wake up with a few less calories in you...

Pick your poison wisely

No form of alcohol is healthy when consumed in excess. However, as alluded to earlier, less than 5% of the calories from alcohol actually end up stored as fat. The rest is urgently burned off and eliminated due to its toxicity.

With this in mind, opting for drinks like spirits and dry wines which contain mostly alcohol and very little else makes sense on paper. Other drinks like beers, ciders, 'alcopops', sweet wines and cocktails all contain additional (non-alcohol) calories, mostly from carbohydrates.

An average pint of lager, for example, contains 10-15g of carbohydrates. Ciders can have up to four times that amount and the sky’s the limit when it comes to some cocktails...

With that said, a case can be made for drinks other than spirits and dry wines. This all depends on how you tolerate certain drinks.

For some, the strength of spirits means that hitting the hard stuff thinking it might be ‘healthier’, comes with a strong risk of getting really drunk and drinking way more than usual. Not to mention not giving a second thought to a large kebab with cheesy chips.

Know what works best for you and stick with that.

Avoid high-sugar mixers

This is a simple one. Avoid regular soft drinks and fruit juices if you’re having mixers with spirits. Over the course of a night these can add a huge amount of extra calories (especially sugar) which you could really do without.

Instead, go for soda water and lime or a slimline tonic. PH’s 250 or 500 effervescent tabs mixed with water have also been known to make for a surprisingly good gin and tonic too!

If you have to have soft drinks like coke or lemonade, opt for diet/zero varieties.

Do some exercise

As I mentioned before, your body only tends to store fat effectively when you're in a calorie surplus, so increasing your calorie expenditure by training on the day of your night out can help minimise your booze-induced calorie surplus and the associated fat gain.

It’s important to note that large alcohol intakes have been shown to significantly impair recovery and adaptation processes, so don’t count on these sessions to provide any major performance gains!

Also, make sure you properly rehydrate after any exercise. Since alcohol can cause dehydration, it’s not a good idea to compound this by starting your night out dehydrated.

A post-session PH 1500 drink can help you rehydrate quickly and also act as a preload before you head to the pub, helping you stay hydrated for longer when the vino starts to flow. 

Dance, Dance Dance!

Throwing some shapes will significantly add to your energy expenditure and tip the calories in / calories out scales a little more in your favour. An hour on the dance floor can easily equate to a few hundred calories burned (especially if your moves resemble Jonny Tye's...).

Plan for the day after

As mentioned, bad habits the day after a boozy night can be a major contributor to the associated fat gain. These tips might not be particularly appealing the morning after the night before but your body will thank you in the long run...

  • Plan your nutrition, starting with a healthy breakfast. This can prevent excessive calorie intake by stopping you from binging on junk
  • Drink plenty of water and get an early night. This helps to remedy the poor sleep and dehydration caused by last night’s antics, meaning you can get back into your normal, more waistline-friendly routine ASAP. Mixing a low-cal PH tab (strength dependent on the hangover severity!) with a 500ml (16oz) glass of water can also be beneficial to replenish any electrolytes lost the night before
  • Go for a walk. There’s no strong evidence for this one but common sense suggests that some light activity might help your hangover and it can prevent your energy expenditure nose-diving if you’d otherwise end up on the sofa all day

A final word on training & performance

Of course, it's not just alcohol's impact on your waistline that you should consider when deciding whether to let yourself go once in a while. It’s worth acknowledging the potential negative impact on training & performance conducted around your night out.

Research in this area is both limited and at times equivocal but several studies have linked high alcohol intakes with potential impairments in strength, power, muscular endurance and cardiovascular endurance.

Moreover, detrimental effects on hormonal and immune system responses, rehydration and post-exercise muscle protein synthesis and glycogen replenishment have been suggested and can all hinder recover and adaptation to training.

No big surprises there to be honest, but it does suggest that, if you're looking to make big strides through your off-season training, you’re best off keeping the big nights out to a minimum.

What I would say is that these studies assessing the impact of 'binge-drinking' involve an intakes of ~1 gram of alcohol per kg of body weight. That's roughly 3 and half pints of beer or about 4 glasses of medium white wine for someone weighing 80kg, which would constitute a reasonable night out for some and a relatively quiet one for others! The effects of lower amounts like the odd bottle of beer or glass of wine with dinner are less clear cut but likely to be more negligible.
