Nutrition and Calorie Tips

Healthy vs unhealthy option?

Dr Nancy P

Healthy vs unhealthy option? 🥗

Restaurant dining can be a bit of a minefield if you’re trying to watch your calories or lose weight. As I’ve said before, we often have a number of preconceived ideas about which the ‘healthier’ option is and equate that with lower calorie. In reality sometimes things aren’t quite as you’d expect.

Another great example of this is pizza express option. The Nicoise Salad with dough sticks is certainly a healthy option – full of fibre, lean protein and micronutrients.

You may order it assuming it’s one of the best options to go for – and it is a great choice! But you may also assume it was a lower calorie option, and therefore probably not think twice about having the dough sticks with it etc. You may even avoid what you really wanted, a lasagne or pizza, because you assume the salad is lower.

However that’s not actually the case. In reality the lasagne is actually lower calorie and fat than the full salad with dough sticks. The difference isn’t that large but it is there nonetheless. Now if you want the salad because you like it then definitely go for it, but if you’re choosing it when you’d prefer the lasagna maybe stick to what you like! If you do want to reduce the calories then the Nicoise without the dough sticks or dressing is the best option.

Enjoy 🤗

Tuesday Tip: Don’t Avoid Carbs

Tuesday tip: Don’t Avoid Carbs 🍞

Many people believe that cutting carbs is the answer to weight loss. Whilst cutting out carbs can work for some people, it’s the reduction in calories that may accompany it that provides the benefit, not the avoidance of carbs per se. This is usually because avoiding carbs has resulting in avoiding highly palatable, calorie dense foods which are often high fat too e.g. pizza, chips, pasta dishes etc. So rather than focusing on carbs as a food group, you’re better off focusing on the high calorie, low nutrient quality, easy to over eat, aspects of your diet and work on reducing them rather than focusing on carbs.

But don’t low carb diets and keto diets result in better fat loss? No actually they don’t. A recent review of studies looked at studies where food was controlled – so participants were given specific foods to eat (ie a tightly controlled study). Comparing diets with the same calories, same amount of protein but different proportions of carb, and fats found that there was NO difference in fat loss, weight loss or energy expenditure. These were lab conditions so any confounding factors were reduced. There was a small difference between the low fat diet and low carb diet – showing that low fat was marginally better for fat loss but the difference was so small that it isn’t enough to make a real difference to overall weight loss.

So what does this mean? It means you shouldn’t avoid carbs – they’re good – we need them for energy and brain function. However there are certain types of food we tend to associate with ‘carbs’ that it is worth reducing or having in moderation if you’re trying to lose fat. These include restaurant meals/takeaways, fancy coffees, alcohol, ‘junk’ food snacks etc. These can all be included in your diet but you may wish to reduce the frequency or quantity to help with fat loss.

Keeping carbs in your diet will keep you happy and if you’re happy you’re far more likely to stick to it. If you stick to it it will be sustainable and that’s what we want!

Happy Tuesday 🤗

Protein smoothie for protein….. erm… or not?

Dr Nancy P

Protein smoothie for protein….. erm… or not? 🥛

I’ve talked before about the marketing power of “protein” and how snacks (and other products) are often promoted as “healthy” or better because they contain X amount of protein. The reasoning behind this is the fact that increased protein can help with improved satiety (feelings of fullness) so CAN help to prevent overeating. Also those working out may want to focus on protein to help with muscle building.

Unless you’re a bodybuilder or athlete you probably don’t need to go out of your way to take in extra protein as most balanced diets contain far more protein than the average person needs. However you may still wish to focus on higher protein foods and snacks to help keep you feeling full.

So you may well see this protein smoothie and think it would be a good option as a post workout drink or snack. However for 350ml it’s around 207 cals (which is fine for a snack) and contains 7.7 G protein which is pretty good I guess for a fruit drink.

Oh but this is awkward… you could instead have a 350ml of skimmed milk for a mere 123 cals, and it will actually provide you with MORE protein – 12.6g in fact! And aside from the fact it’s lower calorie, and has more protein, it’s also far cheaper – costing around £0.24 for that amount (vs £1.86 for the same quantity of smoothie). The lacto-free skimmed milk also has similar calories and protein (though it is a bit pricier at £0.48) but also a great option – and there are flavoured options out there too if you want a fruity drink that also have similar protein and calorie levels! So plenty of options!

Cheers!

Tuesday Tip: Artificial Sweeteners

Are artificial sweeteners bad? There is a lot of concern out there over artificial sweeteners/sugar substitutes. The 4 most common sweeteners are saccharine, sucralose, aspartame and stevia (this is a natural sweetener but is used in the same way and subject to similar claims).

Proponents of the “sweeteners are bad” message often claim that they cause are toxic, cause cancer, and cause insulin spikes and weight gain. In fact there is no scientific evidence that any of them cause cancer (or any disease). The studies used to support this view are on rats, and with excessively high doses. In one study rats were given up to 5,000 mg/kg bodyweight of asparatame. A Diet Coke has 187 mg (which equates to approx 2-3 mg/ kg bodyweight for a human adult). If you scale that up to humans (irrespective of the fact there’s no evidence humans respond the same way) then that’s the equivalent of over 2000 cans a day of Diet Coke. Only one study showed a possible link to blood cancer in rats (not humans) and even then it was a correlation (not the same as causation).

The most recent claim is that the sweeteners “trick” your brain into thinking you’ve had sugar and cause an insulin response (which then causes you to eat more sugar). This simply isn’t true – insulin isn’t released unless sugar is present, no calories, no sugar = no insulin response. Others claim that diet drinks cause obesity. Obesity is caused by consuming excess calories, but sweeteners contain no calories so they can’t possibly cause obesity. They can’t work against the laws of thermodynamics!

Some argue that it negatively affects gut health but as the gut doesn’t have much involvement (there is nothing to be absorbed) this isn’t the case. Studies have only shown an impact with extreme consumption (we’re talking over 8 litres of diet drinks per day every day).

Some people are sensitive to some sweeteners (just as some people are sensitive to a range of foods) and obviously if it doesn’t agree with you then clearly don’t have them . But sweeteners can be a really helpful way to replace a calorie dense sugar with something of similar taste but no calories, so can really help aid fat loss.

So consuming them in moderation is perfectly ok!

Happy Tuesday 🤗

“I’ve put on 3kg overnight.. it must be fat!…..”

Dr Nancy P

“I’ve put on 3kg overnight.. it must be fat!…..” 😳

You hop on the scales in the morning and to your horror you’ve put on several kg seemingly overnight! Like most of us the first reaction is probably to feel demoralised and demotivated, think all your weight loss efforts have been wasted and assume you’ve put however many kg of fat on overnight.

I do say this a lot, but that’s because it’s true – the scales are not a very accurate measure when it comes to changes in bodyfat levels. Short term, significant, fluctuations in scale weight are normal and natural – especially large ones that seem to happen overnight. These do not mean changes in body composition – so you haven’t suddenly put on 3 kg of fat or muscle. Rather they tend to be related to water levels – intra and extracellular hydration.

Even if you did manage to eat an extra 20000 calories in one day (an impressive feat anyway!) then you STILL couldn’t store that all as 3kg of fat. Some would be expended in physical activity and metabolic processes, including the cost of digestion itself etc. The extra weight you see on the scales in short term fluctuations is water retention and food volume.

The reasons for it may include – a really big meal the night before, especially one that might be high in fibre, or red meat (which takes longer to digest). It could be due to your workout routine recently which can lead to short term fluid retention in the muscles. General hydration levels and salt levels will also impact it – especially if you had high levels of salt in your diet the day before. Hormones play a massive role – particularly for women and can cause fluctuations of up to 5kg doe to water retention. Lack of sleep or high levels of stress will also cause you to retain fluids. Carb heavy meals and alcohol do exactly the same thing too – you retain fluid – short term. Now that is NOT to say you need to avoid any of these things – you should be working out, you should be eating carbs etc but it may help to explain any fluctuations you see.

So if your scale weight is up today, then before you let it get you down, just stop and think about all the reasons it is probably fluctuating. Focus on being consistent with your calories instead, and use things like the way your clothes fit, or longer term trends in weight gauge progress (i.e. if you want to weigh yourself daily then take an average each week and use the trend of that average to gauge if you’re making progress).

Enjoy 🤗
