Tuesday Tip: Boost your metabolism

Dr Nancy P

Tuesday Tip: Boost your metabolism 🙌🏼

We’ve all seen products which claim to boost your metabolism and whilst things like caffeine, Green tea, black pepper do increase metabolism it’s only short term. There are however a few other things you can do to maximise longer term metabolic benefits

# sleep cool

A recent study found that participants who slept in cool bedrooms (<18 C) doubled their amount of brown adipose tissue (tissue that actually burns cals). More brown fat means an increased BMR all day.

# Eat carbs

During exercise your muscles use stored glycogen. If you don’t consume enough carbs glycogen levels will be low and you won’t have the energy to exercise as intensely and you’ll burn fewer calories during and post-exercise. So include carbs with every meal.

# Slow weights

Weights based workouts are essential for building lean muscle and increasing bmr but if you’re rushing the reps you’re missing the benefits. It’s important to be slow and steady in the eccentric phase (lowering) as well as the lifting. Eccentric movements are more muscularly damaging and require more cals to repair. Studies have shown an increased fat burning of 5-9% just by focusing on the eccentric phase.

# Eat fat

Eat fatty foods particularly polyunsaturated fatty acids (e.g. walnuts, sunflower seeds and oil, fish etc). These enhance the activity of genes that control fat burning. Just be aware they are calorie dense so have a small portion.

# Hiit it

Include high intensity interval training in your workouts rather than just steady state cardio. Studies show increased fat loss due to greater post exercise oxygen consumption ie greater post workout calorie burn

# Get salty

Include table salt (which contains iodine) in your meals (or iodine rich foods such as seaweed, shrimp, cod and eggs). Iodine is essential for the thyroid gland which modulates metabolism. You only need 1/2 tsp salt per day.

# Hello sunshine

Exposure to daylight is linked to lower BMI. It regulates your circadian rhythm, controlling your sleep, how much food you consume, how much energy you burn—all essential components of a healthy metabolic rate. So get outside!

Happy Tuesday 🤗 xx

Tuesday Tip: Metabolism Myths

Dr Nancy P

Tuesday Tip: Metabolism Myths 🌶

Social media is full of claims about things that will speed up your metabolism so you burn more calories but sadly most of these claims are false. Here are a few of the myths.

#1 Smaller frequent meals speed it up

Smaller, more frequent meals won’t do anything to your metabolism. Eating 6 small meals or 2 large ones really just comes down to preference. More small meals can lead you to overeat unless you’re being very careful with the portions. So, rather than measuring the size and frequency of your meals, pay attention to calories.

#2 Skipping meals slows it down

Skipping meals isn’t necessarily something I’d recommend but it won’t affect your metabolism. You’d need to be at a massive calorie deficit for considerable time to enter “starvation mode” and impact your metabolism. The issue with skipping meals is you are more likely to binge later, but if skipping a meal works for you and doesn’t make you eat more later then go for it.

#3 Caffeine speeds it up

Yes, caffeine does raise your metabolism, BUT crucially only for a short window of time. To get a significant effect on calorie burn you’d need to keep yourself caffeinated which causes poor sleep, heart issues, jitteriness. Caffeine is a diuretic (you pee more) which dehydrates you, which actually slows your metabolism! If you like a coffee, or need a bit of energy before a workout, then go for it, but don’t think it as a free pass to eat more!

#4 It’s fixed

Metabolic rate is affected by age, gender genetics, health, and muscle mass. More muscle = higher metabolic rate. So it’s important to do some resistance training. Cardio training also spikes your metabolism for a few hours afterwards. Aim for > 90 mins vigorous aerobic work (spin, attack, HIIT, running etc), and >2 strength training sessions a week.

#5 Chilli speeds it up

Chilli makes your food taste better, but it won’t give you much of a boost. The capsaicin in chilli peppers does very slightly increase your metabolism for a short while, but adding it to your food or taking pre-workouts/fat burners with it in won’t make you shed kgs I’m afraid.

Tuesday Tip

Tuesday Tip: Post-workout Protein

Dr Nancy P

Tuesday Tip: Post-workout Protein 🥤

The post-workout protein shake is a common sight at gyms, but do you really need protein immediately after your workout? Well yes and no, and here’s why.

# 1 What was the workout?

If it was a short, low intensity session then no. If it was a long (90 min), weights based session then possibly yes. Protein is needed for muscle repair and building so you may need protein after a long, tough weights based workout. BUT even if your goal is to add muscle you only need a little protein post-workout to kick start recovery. If you take too much your body can’t metabolise it and stores it as fat. Short, low-intensity sessions don’t require you to rush to refuel unless you’re already hungry.

#2 Carb to protein

It’s more important to refuel with a combo of carbs and protein. A ratio of 4:1 or 3:1 of carbs to protein is ideal. The protein kick starts recovery and the carbs replenish energy stores in muscles. For 15-30 mins after a long workout the enzymes which pull carbs in to muscles peak. If you miss that opportunity the enzymes are no longer able to pull carbs in to your muscles which starving them and inhibiting repair.

#3 But what about after I’ve done weights?

You’re unlikely to deplete your muscle’s carb stores during a weights session anyway so you don’t need to rush to get a protein shake in. Instead just make sure you get protein via a balanced meal within 2 hours of your workout.

So you really don’t need to bother unless you’re training for long periods (90 mins), at high intensity (or you’re a body builder). At best you’ll be wasting money on shakes you don’t need, at worst you’re adding a load of extra calories which are just going to be stored as fat. You need to eat protein throughout the day so aim for around 1.2 – 2g of protein per kg of bodyweight. For most people, eating a balanced diet, you’ll get this from your meals so there’s no need to boost the protein further. If you do longer training sessions, or are very hungry after a workout, then the perfect post-workout snack is actually chocolate milk – a perfect ratio of carbs and protein (dairy or soya milk), or some greek yoghurt and fruit.

Happy Tuesday 🤗

Tuesday Tip: Surviving lack of sleep

Dr Nancy P

Tuesday Tip: Surviving lack of sleep 💤 We all suffer from bad night’s sleep from time to time. I’ve talked before about how to ensure you sleep better but here are some tips on how to cope when you just don’t get the sleep you need, without resorting to endless coffees!# 1 Stay hydratedDehydration makes you feel even more tired so start the day with a large glass of water (add a squeeze of lemon for extra freshness). Ensure you keep drinking plenty during the day. # 2 Cold showerTry contrast showers – alternating between hot and cold water stimulates your circulation. Also splash cold water on your face or use a cold damp cloth on your neck to give you a boost.# 3 Use Peppermint oilTry dabbing peppermint essential oil on your clothes, or on a little on a tissue and inhale the scent with a few deep breaths. If it’s in a skin-safe carrier then also rub some on your wrists and neck for an energy boost.# 4 MoveEven if you’re exhausted it’s important to move as much as you can. Walk or cycle to work, go for a walk at lunch, or just try 5 mins of exercises when you get up. Do something outside as the daylight blocks the production of the sleep hormone melatonin, preventing you feeling too drowsy.# 5 Eat rightIt’s tempting to reach for starchy carbs and sugar to get you through the day. Avoid these and instead grab some fresh fruit and protein rich foods (e.g nuts, yoghurt, chicken, fish etc). Avoid heavy meals that use lots of energy for digestion. You can also try chewing peppermint gum; a recent study found it significantly increased alertness.# 6 Power napIf you can take a mini nap at some point in the day it will really help to recharge your battery. Make sure it’s less than 20 mins though or you will end up feeling more tired than before. # 7 Mix it upWhen you’ve not had enough sleep you are likely to be less active and less productive the following day. So try to manage your day by focusing on activities that are “easier”and require less thought. Also try to do something different or mix up your routine to keep you alert.

Tuesday Tip: Post-workout Munchies

Dr Nancy P

Tuesday Tip: Post-workout Munchies 🥤🥪

Feeling very hungry after your workout? Regular workouts boost your metabolism and often increase your hunger. Those dreaded post-workout munchies can make you reach for extra snacks and eat more than you want to which could derail your fitness goals.

# 1 Reconsider your burn

Did you really burn as much as you’re about to eat? Studies have shown that we usually underestimate the calories consumed through food and overestimate the number of calories burned by exercise. As I’ve said in previous posts those fitness machines almost always over estimate and even fitness trackers aren’t as accurate as we’re led to believe. So be realistic when it comes to choosing post-workout foods. Go for something with protein, carbs and fat – and if it’s not a main meal then aim for only about 150-200 cals. A glass of milk (dairy or soya) or chocolate milk is an excellent post workout refuel.

# 2 Are you really hungry?

Ask yourself are you really hungry? Unless it’s a definite yes don’t reach for that protein shake or snack (and remember as I said last week – protein shakes aren’t really necessary for most of us anyway!)

Drink a big glass of water first and then decide. Try not to just get in to the habit of eating after workouts for the sake of it.

#3 Eat regular meals

If you’re starving after your workouts then maybe you haven’t eaten enough earlier in the day. Studies have shown regular meals with a good balance of proteins, carbs and fats results in less desire to eat extra snacks post workout and curb that hunger.

# 4 Schedule your workouts

If you always feel hungry after working out, then simply make sure to schedule exercise before one of your main meals.

That way you won’t need to eat any extra snacks, and thus additional calories, between meals.

# 5 Don’t try to earn calories to eat later

Try not to workout simply for the reward of eating later. Again something I’ve talked about before – try not to reward yourself with food. Exercise itself should be the reward so find something you enjoy – cycling, running, classes, dancing etc and then enjoy the endorphins!

Happy Tuesday 🤗
