Volumetric vs Weight measures…. 🧭

This tip doesn’t just apply to tracking your calories, it’s also important for baking too! You will often find that certain items on tracking apps / recipes are measured in cups. This method of measuring though is very inconsistent. For a start – which cup? What size is the cup? Well usually this means measuring cups, but UK and US cups are actually different sizes so even that is inconsistent! The other issue is that measuring cups and spoons vary slightly in capacity from manufacturer to manufacturer. In addition people differ in their perceptions of how to fill them e.g. do you have it loosely packed, compressed, levelling off the top, heaped etc. So whilst these measures give you a ball park figure they aren’t that precise. For some things this won’t matter – a cup of lettuce for example is so low in calories that it won’t make much difference. However with certain things it can make quite a difference.

In this example, oats are often measured in cups, especially on tracking apps. A serving is half a cup which is assumed to be 40g. So you may think it’s ok to just go with a half cup when scooping out your oats. In reality though a loosely filled half cup is actually closer to 55g. This is an extra 56 cals per portion. 56 cals may not seem like much but if you were also measuring other things in your oats with cups/measuring spoons (like a tbsp peanut butter, tsp jam etc etc) and all those are out too then you’re consuming quite a bit more than you realise. If you’re doing that daily that’s over 390 cals a week, which is enough to affect your progress.

So where possible go for metric measures i.e. grams or ml on a kitchen scale if you want to track your calories more accurately, especially for calorie dense foods.

Enjoy 🤗

Tuesday Tip: Good Egg, Bad Egg?

Tuesday Tip: Good Egg, Bad Egg? 🍳

A recent study suggested that eating eggs (specifically yolks) was linked to a 14% increase in early death (due to raised cholesterol primarily). High levels of LDL cholesterol long term are the strongest risk factor from a blood lipid point of view for cardiovascular disease (whilst HDL cholesterol is considered “good” cholesterol so high levels are not such a problem).

Although increasing dietary cholesterol can impact LDL levels, it’s worth noting that the overall impact is minimal. You would need to have extremely high levels in your diet, doubling the typical “western” diet levels to have even a minor effect. In comparison the effect of high levels of saturated fats is much more significant. And in fact it’s really the ratio of saturated to polyunsaturated fatty acids in the diets that are more important.

So what does this mean? Saturated fats are more closely linked to increased risk of disease and death than dietary cholesterol itself. Try to swap out some saturated fats (e.g. butter, chocolate, cakes, pastries, deep fried foods and fatty cuts of meat) whilst increasing polyunsaturated and monounsaturated fats like extra virgin olive oils, almonds, walnuts, macadamia nuts and oily fish.

It’s also wise to increase fibre levels which helps decrease cholesterol levels via essentially grabbing onto bile in your digestive tract, preventing it being reabsorbed and recycled into cholesterol in your liver.

So what about eggs? Eggs get targeted due to their cholesterol content. However they are low in saturated fat and therefore their impact is clinically insignificant. They are instead an excellent source of protein, omega-3’s, vits A,B,E, D and zinc, phosphorus and potassium. This means we can safely consume eggs without risk of cardiovascular disease or death increasing.

I don’t have time to track my calories….

I don’t have time to track my calories…. 🍏

People are desperate to lose fat/weight but often say they just don’t have time to track what they eat. Now whilst it’s perfectly possible to lose weight without tracking calories, there’s no denying that accurately tracking them is an extremely effective way to do it. And in addition is gives you an excellent foundation of knowledge for maintaining any results you achieve.

I completely understand that it can be really stressful trying to balance work, social life, childcare or caring for other family members etc and perhaps even more so right now with home schooling/home working, but I am not sure the excuse of “no time” always rings true.

On average, in 2020, people in the UK spent 2hrs and 24 mins a day scrolling social media/messaging etc, 1hr 11 mins watching TV and 1 hr 21 mins online shopping. That’s an average of nearly 5 hrs a day! Now whilst you may claim you don’t spend anywhere close to that amount of time doing those things I bet you spend more than 30 mins on these activities (or similar ones)? Studies have shown that tracking your food; whether it be in an app or physically writing it down, takes no more than 30 mins a day. That includes weighing portions, barcode scanning items that are pre-packaged and then actually entering it into the app/writing it down and adding it up.

You don’t have to devote your life to tracking food, but if you can’t spare a few minutes to think about what’s on your plate before you eat it, you won’t make changes to what you eat and drink to reduce calories. In short – it won’t work. You have to make a change.

If you’re telling yourself you’re too busy or don’t have time to put any attention on your diet, then you’re right – you don’t – but that’s not because you don’t want to, it’s because it’s not enough of a priority right now. Once it becomes a big enough priority you’ll find you do in fact have time. Don’t kid yourself into thinking you’re too busy to track or that it’s a bigger job than it really is, and maybe reconsider the time you spend on other activities that are perhaps not as important for you?

Enjoy 🤗

Tuesday Tip: Understanding Metabolism

Tuesday Tip: Understanding Metabolism 🤓

Despite what you might think most of your daily calorie burn doesn’t come from exercise. It’s driven by your metabolism (converting food cals to energy) which determines the number of cals you need to maintain your weight.

Your calorie burn consists of:

#1 60-70% Basal metabolic rate; the cals you need at rest, to survive; breathing, digesting, filtering waste, nothing more. It varies with body size (bigger = higher bmr), composition (more muscle = higher bmr), age (younger = higher bmr), genetics, hormones (thyroid hormones) and health (ill = higher bmr).

#2 10% is from food thermogenesis (digesting food). Protein requires the most to digest. 0-3 percent of fat cals are used to digest it, 5-10 % for carbs and 20-30 % for protein. But as food thermogenesis only accounts for 10% of daily burn, eating more protein will only have a small effect on your metabolic rate.

#3 20% is from physical activity; walking, workouts, and day to day activities; typing, carrying heavy loads, standing, fidgeting, shopping, etc.

So if you aren’t seeing the results you want, but are tracking your food right, then maybe you’re overestimating your calorie burn? There’s lots of tips out there to boost metabolism e.g. eating more frequently, or not eating late at night etc but few have studies to back them up.

Some tips which are backed by science include:

# including strength training in your workouts. Boosting your muscle mass increases your BMR and burns more calories at rest. You don’t have to lift big weights, body weight exercises are also effective.

# increase intensity in your workouts; short bursts of intense effort increase afterburn e.g. intervals when running, swimming or cycling, or doing workouts that naturally include it like hiit/ bodyattack/ circuits etc.

#3 Eat enough protein. You’re still only contributing a little extra burn, but by ensuring you have protein with every meal you will not only burn a little more digesting, but more importantly you’ll feel fuller for longer, and you’ll have amino acids to support muscle recovery and repair.

Fasted vs non-fasted Exercise

Fasted vs non-fasted Exercise… 🏃🏼‍♂️

There’s a fair amount of confusion out there about whether you’re better off exercising fasted (on an empty stomach) or after you’ve eaten something (non-fasted) and whether one is better or worse for fat loss.

The confusion arises because people often talk about how exercising on an empty stomach increases fat oxidation. This then gets conflated with fat loss. Fat oxidation is the process of using fat for energy in the body. When you eat something the body secretes insulin to aid in the processing and metabolism of the food for energy and storage. Insulin reduces fat oxidation, so less fat is used for energy. So the argument is that if you haven’t eaten anything yet that day then you won’t have secreted any insulin and therefore fat will be oxidised and used for energy.

Whilst this is true – you will have more fat oxidation, it doesn’t actually mean more fat loss. Fat loss is dependant on overall calories consumed, on average, over the day/week/month etc. Even if you exercise before eating, you still need to have a calorie deficit for that day otherwise any excess calories will still be stored as fat. So It makes NO difference to fat loss whether you choose to eat before or after exercise.

For some people they prefer to exercise on an empty stomach, but for others they need some food in their system to workout. From a workout perspective if you haven’t eaten yet then you may find you fatigue faster and aren’t able to work as hard, so you may end up burning fewer calories. So it’s very much personal preference!

Enjoy 🤗
