Ep. 20 – Is Intermittent Fasting The Best Diet For Weight Loss?
Welcome to the 20th (woohoo!) episode of Vegetarian Health and Longevity from Hurry The Food Up and Sports Nutritionist James LeBaigue.
Intermittent fasting, or time-restricted eating, has a lot of attention right now when it comes to losing weight.
Is it as good as people suggest?
There was a new study out that investigated this exact question and compared it to a usual eating pattern.
The answers might surprise you, and in this episode I’ll dig into the results and how you can use them to your own advantage.

Why all the buzz about intermittent fasting?
Intermittent fasting is something which has a heck of a lot of attention right now, with people using it for a variety of reasons.
Some people claim it helps to improve your metabolism, others suggest it can help you to live longer, while others say it’s the best diet to lose weight.
And if you search online you’ll be sure you can find an article that says something to this effect with heaps of personal testimonials that agree with it.
There was a study I saw recently which grabbed my interest because it was looking at the effects of intermittent fasting on weight loss compared to following a classic eating schedule.
Other studies weren’t as good
Now many studies in the past have done something similar, but there was something special about this one and it made it a much stronger and more reliable study than previous studies, so I was super excited to read about the results.
In this episode we’ll dive into this, and by the end you’ll know whether intermittent fasting has greater benefits for weight loss and whether it’s something that you should follow.
Intermittent fasting has various names and definitions, and there’s not an industry standard definition of it.
You may also hear the umbrella group of time restricted eating used, which, as the name suggests simply means eating within a defined period of time and not at any other.
The windows of eating vary too, with some protocols suggesting a 6 hour eating window, for example 6am to 12pm, and others suggesting a 12 hour window, like 7am until 7pm.
Previous studies have tried to examine the effect of this time restricted eating on weight loss, and the results have generally been positive and shown greater effects within the restricted group.
The issue with time-restricted eating studies
However, there’s a key problem with many of these studies which actually stop them from being that valid, and this is what a recent study addressed and corrected.
The study that I’m talking about was called “Effect of Isocaloric, Time-Restricted Eating on Body Weight in Adults With Obesity” and it used a restricted eating protocol of 8am to 6pm, meaning that participants weren’t allowed to eat outside of those times.
It also required the participants to have consumed 80% of their calories by 1pm, meaning the bulk of their food was in the morning.
The participants of the study were split into two groups, and the other group were allowed to eat at any point between 8am and midnight, with the requirement to eat 50% of their calories between 5pm-8pm, so much more in the evening.
Over a 12-week period, the researchers tracked the participants’ weight, which was the main aim of their investigation.
At the start of the study, the researchers hypothesized that those in the time-restricted eating group would lose more weight than the usual eating pattern group, based on the findings from previous studies suggesting that the restricted groups usually lost more weight.
What were the results of this study?
In this study though, that didn’t happen.
On average, participants in the restricted group lost 2.3kg of weight and those in the normal pattern group lost 2.6kg, and there was no statistical difference between these, meaning that the two dietary protocols showed the same benefits for weight loss.
This is super, super interesting and goes against the grain of previous research—so why is this?
Before we go into the results, just a quick hi to say that if you’re interested in using the vegetarian diet to lose weight then you should check out our free vegetarian weight loss meal plan.

Alright, back to the episode.
What was different about this study?
So, the results of this study might be different to the others because of how the researchers managed the participants diet.
In this study, the participants agreed to only eat the food provided by the research teams, within the specific windows.
Now this is a critical point because what the researchers wanted to control was the calorie and nutrient composition of food.
Their concern was that other studies did not do this adequately.
In some cases they did control calories but did not control macronutrients – so protein, carbohydrate and fat – and in other studies they didn’t properly manage calories at all so it wasn’t a fair comparison.
Thermic Effect
And there’s something called the thermic effect of food which is incredibly important in studies like this.
When you eat food, your body has to spend energy digesting it, and different foods require different amounts of energy to break them down.
So if the researchers don’t control for this they could see differences between the two groups which were simply down to the nutrient composition of their food, rather than the calorie amounts.
Imagine one participant in the control group was eating 150g of protein a day but not much fat, and another participant in the time restricted group was only eating 60g of protein a day but lots of fat, but overall they were eating the same total calories.
Protein has the highest thermic effect of food while fat has the lowest thermic effect, which means the person eating more protein would actually have to spend more energy, or calories, digesting the protein, meaning that the amount of calories they actually absorb to then use for energy is lower than the other person.
So as a side tangent, this is one of the reasons why high protein diets can be beneficial for weight loss and why we focus on high protein recipes at Hurry The Food Up.
It’s not always easy on a vegetarian diet but if you use the right nutrients then you can still get all the benefits!
But in this study, the participants diet was completely managed by a team of dietitians, and the participants reported excellent adherence to the dietary protocol.
Overall, this is fantastic because it means that the weight loss effects should really hinge on either the calorie amounts or the dietary protocol.
As I mentioned, in this study there were no statistical differences in weight loss between the two groups even though they followed different protocols.
Because previous studies suggest that it’s the protocol that matters, the researchers should have seen better weight loss results in the time-restricted eating group but because they didn’t, they concluded that it’s the calories that matter, and not the protocol.
What does this mean for you?
Now this is amazing and it fits with the mantra that I follow and always suggest to people.
So I mean take this with a pinch of salt if you want, I am biased and genuinely pleased to see these results because it confirms my way of thinking.
But I always, always encourage people to follow the diet that suits them best–at least within reason.
In my opinion, there just isn’t enough research out there to show that any diet is superior to others when it comes to a pure weight loss point of view when calories are adequately controlled.
By that, I mean that you could follow intermittent fasting or you could eat three meals a day and lose weight, as long as your portions and therefore your calories are correct.
So really it comes down to what diet is the most sustainable for you? What diet or eating pattern are you going to be able to maintain not just for weeks or even months but for the rest of your life?
Because once you’ve got to your target weight you need to stay there and to do that you need to follow the exact habits that you were following, just with a little more food to stop weight loss.
Some people find this really tricky to grasp, and I totally get it.
It’s a marketer’s world
There is so much good marketing out there, so many wonderful success stories, for pretty much any diet, which means you can easily get sucked in and believe the hype.
But the truth is you can keep it really, really simple with weight loss. Find an eating plan that you enjoy, that works for you and you feel you could sustain for the rest of your life.
If it feels too restrictive, you’re having to use loads of willpower to sustain and you constantly feel hungry or tired, then it isn’t for you.
My personal recommendation is almost always to go down the more regular eating pattern of three meals day with snacks if appropriate.
From my experience with clients I’ve seen such better adherence over the long term coupled with better energy levels.
But if that really doesn’t work for you, or for example you find that time-restricted eating helps you to control your calories while losing weight then fair enough, you go for it.
Just remember that it’s not a magic bullet and you still need to manage your diet once you hit your goal.

Ep. 24 – Is This Surprising Factor Sabotaging Your Diet?
Welcome to the 24th episode of Vegetarian Health and Longevity from Hurry The Food Up and Sports Nutritionist James LeBaigue.
There’s a recurring theme that I see when working 1:1 with clients and with members of The Vegetarian Protein Fix.
Typically, they have struggled to stick to a diet over the long term. They might have been able to for a couple of months, even 6 months, before old habits creep back in and before they know it, they’re back where they started.
There might be lots of reasons for this. They don’t have enough time and life got busy. Work was stressful. They had an injury. They went on holiday.
There are loads of “problems” that have stopped them and made it difficult.
But usually, when I speak to them and really delve into this there’s something deeper, something darker that is keeping them from sticking to their diet over the long-term, and I think it’s something that so many people struggle with.
And if more people were able to understand this and improve it, I am absolutely sure that it would benefit so many lives. Now this could be in relation to weight loss or just general health living because it’s something that crosses all spheres and walks of life.
I’d like to dive into this in this episode, and show you just how powerful this change can be and how you can use it in your own life.

My experience
Throughout my time working clinically in family medicine, and as a nutritionist within sport, I’ve come across so many different attitudes to food and dieting.
Some people are so carefree around food and have no emotional attachment to it, going as far as to forget to eat, and not eating enough unless they have a specific plan to follow.
Others love food and enjoy all different aspects of it, and don’t have any concerns around weight or managing their diet. Others love food but hate their diet: they often feel ashamed, guilty, and they aren’t where they want to be in terms of their weight or how they look.
Suffice to say that there are so many different perceptions of food and it’s such a complicated matter, but apart from a small group of people, everyone has an area that they could benefit from working on.
You see, there’s something which many people don’t actually think about when it comes to food.
Focusing on the wrong thing?
People often focus on the nutritional value of food, and I’m guilty for it too. I talk about calories, about protein, carbohydrate and fat, vitamins and minerals, and the quality of the food that you’re eating.
And people connect what they eat to their weight in either a positive or negative light, with it either helping or hindering them to reach their goals.
But very few people that I’ve come across in my time truly have what I would call a good relationship with their food. Where they not only understand the nutritional content and context of their food but they also enjoy the various different aspects of it like pleasure on an individual level, on a social level and how it can support them with their endeavors.
And this is something which I think many people would benefit from improving because it can honestly transform someone’s life.
The perceived problem with your diet
When people struggle to stick to their diet, they’ll often give me a reason like “I was a bit too busy to plan my food” or “Work was stressful and I couldn’t stick to my diet”.
While these might well be problems that they are facing, these are really just the symptoms and the end-result of their diet either not being sustainable or not having controlled enough of the factors which can ruin adherence.
And commonly, they’re skipping over the part which is really important because they are just focussed on this end goal metric of “Am I following my diet”.
So while they think their problem is that they don’t have enough time or that work is too stressful, the issue runs much deeper.
What often happens is that they get into a negative cycle. They end up eating food that they don’t really want to, sweets, treats, highly processed ready meals that are of low nutritional value, and this in turn makes them feel bad. They feel bad about their diet, about themselves, and weight gain is common in this phase.
So they get into a vicious circle where things aren’t going well and they end up continuing to eat poorly, which spirals things further. Food is an ever constant that they can’t get away from.
Then at some point, they might decide to try again. They summon the willpower to tackle it again, to cut out all that “bad” food that’s causing problems.
This is a really harmful cycle to be in because you’re in a constant negative state towards yourself and, perhaps more importantly, to food. Food is essentially seen as an evil thing that’s causing the problem, rather than something which has so much wonderful value, both nutritionally and on an individual level.
The actual problem
And this is where many people are focusing on the wrong thing. They are looking at the end result, which is adherence to the diet and, depending on your goal, weight loss.
But rather than thinking about that, I would strongly encourage people to work on the way they think about food and start fostering a positive relationship with it.
Now this might sound a bit airy… What am I actually talking about here? What does this mean?
Ok, let’s go back a moment. I mentioned that food is a constant that you can’t get away from. It can be hard to stop thinking about it and it’s hard to separate the negative association, especially when you aren’t reaching your goals. And this is obviously true from the sense that you need the energy from food to keep you alive, so it’s not like you can just ignore it and it goes away.
But if you think about food in a bad light this can be incredibly overwhelming because you come into contact with food so many times throughout the day, so you’re being exposed to it multiple times.
And while food might be part of the issue in terms of your weight or body image, it’s not really the actual cause, in the sense that food is just an inanimate object that doesn’t move or have feelings.
You are the one who has the feeling towards food, and how you think about it can have such a significant effect on both your life and your weight
So how do you change this?
I worked with a 1:1 client who had a bad history when it came to food. They were a normal weight throughout their 20s, but by 35 and after kids they had put on a lot of weight, would binge eat and then try to lose weight, and this happened several times.
When I spoke to her it was clear that she had a very negative association with food. She would say she frequently ate “bad food” even though she tried hard not to, and it often made her feel guilty and ashamed for doing so.
She didn’t like to talk to her family about it because it made her feel very emotional.
Instead of focusing directly on weight loss, which was her goal, we instead started working on improving little parts of her diet at a time.
Initially this meant talking about foods that she genuinely enjoyed, both ones that were classically healthy and unhealthy. So this included things like sweats, treats, and then other foods like gnocchi and bread.
Is food Ggod or bad?
In her mind, all of these things fell into the bad category because she felt like they were the cause of her weight gain. We talked through this, about calories, about moderation, and how, if we set her diet up correctly, these things could be included and she could still lose weight.
This was a bit of a mind-blowing suggestion to her. She could eat the foods which she enjoyed, that she found fun but had always associated them with weight gain, but actually lose weight?
Little by little, we added more fruits, vegetables and wholegrain carbohydrates into her diet, less high fat dairy and more low-fat dairy, while including those things which she really enjoyed.
Along with that, I was really careful to emphasise that she could enjoy meals out with friends and family, she could go to a coffee shop and eat cake and it was OK.
I remember how her perspective of food completely changed over a couple of months. She no longer saw food as the enemy, and instead something that was integral to her life that could bring happiness from a personal perspective but also use towards her goals.
She shifted her mindset to one where food was actively helping her with her goals rather than being something that would detract from them.
And when you think about it, it really is true. When it comes to weight management, whether that’s weight gain, loss or maintenance, calories are the determining factor for how well you achieve that. Realistically, you can eat any food within that if it’s in your calorie budget, so food and calories are simply a tool.
For weight loss
And if you look at the research, there’s plenty to suggest that cultivating positive relationships with food can be beneficial, especially in terms of weight loss.
Sure, there are some nuances here and one of the things my client worked really hard on was gradually improving her diet with the additional of more of the classically healthy things.
It didn’t just happen overnight and was instead something she had to continually optimise over months, but knowing that she had power over her food was an incredibly empowering revelation for her.
Food is not the enemy
Now some people find this a really hard thing to come to terms with because they have always thought of food as the enemy. The truth is that it isn’t and, honestly, how you perceive food, how you choose to eat, is the issue.
That might sound like doom and gloom but it isn’t. What you need to know is that you have control over food. You can master it and you can change the way you think about it, and if you start seeing it in a more positive light then it can really melt away all the negativity that you might be encountering on a daily basis.
A nice way to do this is to come at this from the approach of “What can I add, rather than subtract, to make this healthier?”.
If you start from the basis of adding food rather than removing, it changes the viewpoint. If you’re removing food it’s because it’s “bad”, but if you’re simply adding to it you’re creating something which is healthier and the association is positive.
Now of course it isn’t quite as straightforward as this and there still has to be balance, but this is where moderation comes in.
Especially at the start, and if you’re struggling to change habits, I have found it so much more helpful to encourage clients to have those guilty-pleasure foods, for lack of a better term, in small amounts, more regularly, than to restrict them, really pine for them, and then binge because they have got to breaking point.
And if the rest of the diet is balanced in terms of calories then you can still achieve your goal, it’s just knowing how the guilty-pleasure foods fit into your calorie budget for the day.
Now all of this is something I go into in more detail in Episode 7 of this podcast, called “What’s The Best Diet For Long Term Weight Loss? Diet Myths Explained”.
I debunk some of the common misconceptions around weight loss and diets, and what I go through there will really help you to put things into perspective with today’s episode.
So I hope you found this episode useful. If you did, then please give the podcast a quick review on whatever platform you’re listening on.
It helps the podcast to spread to more like minded people like you, and it’ll only take a moment. Thanks so much, and we’ll speak soon.
