Do you need exercise, to lose weight?
The age-old -Do we need to exercise to lose weight? The answer is not straightforward.
-It is widely accepted that following a calorie-controlled diet is the most important factor when losing weight, calorie deficit is crucial to your weight loss effort. If you are consuming a surplus of calories but only doing moderate exercises, even though you are exercising it may not be enough to lose weight and this leads nicely to our first point: how much exercise would we need to lose weight without cutting calories?
How many calories are you safe to cut out?
-I know that for some people, exercise isn't an option( for reasons of health conditions or restricted mobility) But let's say you decide to cut your calorie intake instead of doing any exercise -can this still result in weight loss? The answer is yes, provided you are tracking your calorie intake accurately and creating a calorie deficit for example using more calories as you consume..
-However, by trying to focus only on reducing your food intake, you may need to adjust your expectations of how quickly you will lose weight, but that depends on how much weight you want to lose. Cutting calories from food intake alone could require quite a drastic and unwarranted reduction, leading to hunger, low daily caloric intake, and difficulty continuing... I recommend choosing the level you find sustainable for you it will last a little more time, but constant progress will lead you to the desired goal. I can't tell you a minimum calorie level for weight loss, but that depends on your goal and activity level. Too low will be extremely challenging and is not recommended because you are not getting the proper nutrients to keep your body healthy and support your daily activity level.
Train more to lose more?
-The answer depends on the type of training or exercises you focus on, how frequently, and how many calories you burn. The challenge is that the more you train the more you burn calories and it makes you feel hungry. This is a natural response by our body to replace used calories if you are trying to use the exercise to create a calorie deficit, it is important to control the number of calories you are eating back to ensure that you have not eliminated the deficit. This is the easiest way and generally recommended to try it is one of the principles of weight loss; -which is to create a calorie deficit through eating less AND exercising more.
My verdict?
-The best approach to weight loss is that works for you. If you are unable to exercise, then you might need to focus more on monitoring your food intake accurately and setting yourself a sustainable and successful rate of weight loss per week. If you can achieve a balance of following a calorie-controlled diet with an increased level of exercise ( compared with what you were doing before ), then you should see a slightly faster rate of weight loss.
-However, weight loss is very individual and is influenced by lots of factors, so this is a very general figure. If you regularly exercise intensively then it will be really important to eat back the calories.
Intermittent Fasting: What it's all about?
-I have heard that, the first introduced 5:2 fasting idea was on a TV show in 2012 by Dr Michael Mosley (he passed away in 2024 )since then, fasting has grown in popularity and, obviously, now we can find fasting diets with lots of variations in term of the length of the fasting window, and calories intake on the fasting days.
-Is fasting healthy and beneficial for weight loss and maintaining a healthy weight? Is one fasting regime better than another? Let's discuss it!
Weight loss .....🤔
-Intermittent fasting can help with weight loss, simply because it's a way to restrict calorie intake. Whether it's significantly reducing your intake for two days of the week or minimising your eating times to an 8 hours window every day – these approaches inevitably lead to a reduced calorie intake. Research comparing weight loss in individuals who fasted for two days of the week compared to those who reduced their calorie intake by 20% every day, found no difference in the amount of weight lost. This suggests intermittent fasting is not better for weight loss than simply reducing your calorie intake a little each day.
Health benefits.....-There are studies in the lab looking into the effect of intermittent fasting on health, with very promising results. Some research has been conducted in humans, showing similar effects on blood pressure and insulin resistance. However, in order to improve the quality of the evidence base, long-term studies in humans are needed to establish whether intermittent fasting produces lasting results and positive effects for longevity.
-That said, some research has found that intermittent fasting can result in:
1. Increased insulin sensitivity
2. Reduced blood pressure
3. Reduced bad cholesterol levels
4. Better blood sugar control
5. Improved appetite hormone regulation
6. Increased growth hormone secretion
-Many of these factors will reduce the risk of chronic diseases such as diabetes and heart disease.
-The health benefits of intermittent fasting in humans aren't yet concrete, there's little evidence to suggest it could be particularly harmful if conducted sensibly. So if a particular fasting approach suits you and your lifestyle, by all means, give it a try and potentially you could benefit your health in multiple ways too!
Which fasting is the best?
-5:2 fast...
-16:8 fast...
-Alternate day fasting...
-Warrior diet.....
5:2 fast.....the original and very well known approach to intermittent fasting requires to eat normally for 5 days and restrict calories on 2 days each week for women was suggested restriction to 500 calories on fasting days and men at 600 calories.
However, this has been revised in recent years to recommend 800 calories on fasting days. There is also a 'rapid weight loss' phase to this diet, which recommends having just 800 calories per day for 2-12 weeks. This should only be done under the guidance and approval of a professional
6:8 fast....this approach requires you to fast for 16 hours a day and only eat during an 8 hour window. So for example, eat your evening meal by 7pm then don't eat anything else until 11am the following day.
Alternate day fasting....– this requires you to fasting every other day for an entire day. Some versions allow 500 calories to be consumed on the fasting days, while others require a complete fast.
Warrior diet ....–this approach suggests eating raw fruit and veg during the day, then eating a huge meal in the evening during a 4-hour window.
-Some approaches don't require you to monitor your calorie intake but, rather rely on you naturally consuming fewer calories across the day or week. The premise is that, if there are fewer hours in the day when you can eat, you will consume fewer calories and when you are eating, there's only so much food as you can manage in one meal. This means they can all be effective approaches for weight loss.
-Not all approaches have been rigorously studied, despite it being the most spotlight, the 5:2 approach hasn't been subjected to much long-term research in humans especially. It's mostly backed by research in the lab and the general idea and proposed benefits of intermittent fasting – but currently, there is nothing to say this fasting approach is any better than the others highlighted.
Does when we eat matter? 🤷.....
-There is research that supports the idea of eating earlier in the day and gradually reducing your intake until the early evening. One study found that women who ate their largest meal at the beginning of the day lost twice as much weight as those who ate their largest meal at the end. This is thought to be due to our body's natural circadian rhythm, probably the best time to ingest (eating more calories earlier in the day). This shows that our metabolism is most likely much more active in the first part of the day.
-On top of this, research involving prediabetic men found that if they ate all their calories within an eight-hour window (between 7 am and 3 pm), their blood pressure reduced and insulin sensitivity increased – when compared to eating the same amount over 12 hours.
These findings suggest the importance of meal timing and general dietary patterns for maintaining good health and weight loss.
Bottom line........👊
-If your goal is to lose weight, intermittent fasting could work for you – but, simply because it results in a calorie reduction. So a standard calorie reduction diet could be just as successful. It is really about finding an approach that allows you to stick to a reduced intake most easily. Some people prefer to have two very strict days in the week and then 5 days of more relaxed eating. Others find that limiting their eating window helps to prevent excess evening snacking for example, whilst others find it preferable to moderately reduce their food intake every day.
.5 signs we are not eating enough......🤔
1. You are constantly hungry:....🥪
-The first major sign that the calorie deficit is too severe is persistent hunger. It may seem obvious, right? Leptin is one of the hormones that make us feel full. When our caloric intake drops too much, leptin levels drop. At the same time, the hormone that tells us we're hungry (called ghrelin) increases. This is often what leads to an all-too-frequent cycle in people trying to lose weight—restricting too much during the week and then throwing in the towel and bingeing on the weekend.
2. Your energy levels are at an all-time low....🥱
-Another sign that you're not eating enough is low energy levels. Calories are the units of energy that the body uses to function. In a mild deficit, our body can use its fat stores over time to meet its energy needs, but if we don't feed it enough through our diets to perform even basic functions, we can't expect it to function at normal capacity... So, if in the morning you wake up tired and all the time during the day, there is that state of sleepiness but, you have to do your work, exhausted at the end of each day, especially after physical activity, it could be a warning your caloric deficit is too drastic.
3. You are irritable and snappy....🥴
-You've probably heard the term "hangover" - used to describe the seemingly irrational irritation we can feel before our morning coffee and a bite to eat. But there is actually science behind this answer! Cortisol and adrenaline are hormones associated with anger and anxiety stress responses due to their role in the fight or flight mechanism. These two hormones are triggered by low blood sugar, so the less we eat, the more likely we are to trigger the brain's fight-or-flight centers, leading to feelings of stress, anger, and anxiety.
Because circulating adrenaline levels are higher, malnutrition has also been associated with sleep problems, which can perpetuate feelings of anxiety and the dreaded "hangover."
4. You are constipated...😬
-If you're not putting as much food into your body, you'll probably have less coming out of your body. It's a less-than-pleasant subject, but constipation can be extremely uncomfortable and shouldn't go untreated. You're also less likely to not eat enough fiber, which could contribute to a blockage in your digestive system. You may also consume less water through both food and drink, water normally helps keep everything moving.
Remember, 30g per day is your daily fiber target. It can be a challenge for most people, even when they're not following a low-calorie diet.
5. Your weight loss is stalling.....🤨
-Can eating less make it harder to lose weight?! It may seem counter-intuitive, but it's true. Eating too little can affect your metabolic rate long-term and is likely to make it harder to maintain lean tissue, so while you may initially see a lower number on the scale, this will represent both fat loss and muscle loss. Because muscle tissue uses more calories daily than fat, people with leaner tissue will have a higher metabolic rate. A higher metabolic rate means more calories burned. So losing muscle tissue isn't ideal when you're losing weight because your metabolic rate will drop, making further weight loss more difficult.
-Severely reducing caloric intake for a prolonged period could also prompt the body to actively lower its metabolic rate in an attempt to conserve energy. The scientific name for this is adaptive thermogenesis, but it is also called metabolic slowing. Research is ongoing to improve our understanding of the mechanisms that trigger and promote the slowing of metabolism, but all we know for now is that exaggerating the calorie deficit could be more of a hindrance than a help when it comes to weight loss.
.So what should I do if ...I identify with one or more of these signs?🙋
-If you've been cutting calories for a short period (a few weeks) and notice that you're experiencing some of these side effects, don't worry! Cutting your calorie intake down to a safe level should get your body firing on all cylinders again pretty quickly. However, if you've been eating less... for a few months, you don't need to worry too much about how to increase your intake. This is completely understandable, but there is a chance that an increase in energy intake at this time will cause temporary weight gain.
--To avoid this gradually, the best course of action – is called “reverse dieting”. Although research on this method is still developing, the evidence generally suggests a positive effect. Start by adding 50-100 calories to your current intake and aim to achieve this for 3-4 weeks. Then constantly increase by 50-100 calories every two weeks. This method will not only give your metabolism time to adjust, but it will also be easier to manage if you've gotten used to eating less food for a while.
.Food suggestions to boost your energy and nutrient intake.....🙄
-When looking for foods to boost your energy intake and help you reach your calorie goal, you should choose foods, that are both caloric and nutritious. Nuts are an excellent choice. They are a good source of unsaturated fats, which promote heart health. They also contain protein and fiber, two of the best nutrients to help you feel fuller for longer. Depending on the variety of nuts you choose, you'll also get different levels of vitamins and minerals—vitamin E, folate, magnesium, zinc, selenium, and potassium,............. to name a few.
-Other foods that provide healthy calories are avocado, olives, and fatty fish – all of which are high in fat but are unsaturated. If you currently go for "light" and "diet" versions of foods like yogurt and cereal bars, try swapping a few for regular versions throughout the week. The 'low fat' and 'low calorie' versions tend to be higher in added sugar, so you may find that your sugar intake for the week goes up too - a bonus!
Which exercise is the best for losing, maintaining, or gaining weight?
When it comes to weight management, there are generally three goals people can work..... maintaining a healthy weight, losing weight, or gaining weight.
Exercise is something everyone should try and fit into their routine, regardless of their weight goal. It does much more than burn calories – it improves our cardiovascular health, bone health, quality of life, mood, sleep quality and mental well-being, to name just a few benefits. But, should the type of exercise we do, change based on our personal goals? Let's discuss it!
Lose weight.....If your goal is to lose weight, exercise is a great way to burn extra calories and ,help you create the necessary calorie deficit. So, the best activities to choose, are the ones with maximum calorie-burning potential!
Cardio – This is the best choice for most people who want to use exercise for weight loss – this includes running, spin classes, cycling, swimming (using a trainer), rowing, and walking. Each of these activities will burn a decent number of calories (the more you weigh, the more you'll burn). The "best" thing to do is, the one you enjoy the most and, will therefore do regularly. Start at an intensity that, matches your fitness level - the great thing about cardio is that, you can progress quite quickly and it's really motivating you .... when you can feel your fitness level improving!
-Walking... is great for beginners, because, it's low impact and less intense than, say.. running - and because, it's less intense, you can usually keep going for longer, making it a good fat burner calories.
-Running.... is good for burning calories, in a shorter amount of time.
-Cycling.... is also a great calorie burner and, better for those who, need a low-impact activity.
-Most forms of cardio activity burn more or less a similar number of calories, except walking, which is a much lower-intensity activity. So it comes down to personal preference when choosing your cardio exercises.
-Strength training-his type of exercise is often overlooked, especially by women concerned that lifting heavy weights will result in big muscles. Strength training (or "resistance") training is now extremely popular as people have become aware and have a better understanding of the significant benefits it provides. While lifting weights doesn't burn as many calories in an hour as running, the benefits of this type of workout last beyond the workout session itself.
-Regular strength training builds lean muscle mass, which helps increase your metabolic rate – so ultimately, the more muscle mass you have, the more calories your body burns each day. This means that, in the long run, strength training is excellent for promoting weight loss and fat burning. Lifting weights can also lead to an "afterburn" effect, where your metabolic rate is slightly increased in the hours following exercise. So while you may burn about 200 calories while lifting weights, you can continue to burn another 100 calories throughout the day during recovery.
-High-intensity interval training or 'HIIT':– a buzzword at the moment, HIIT has become very popular in recent years. It consists of performing short periods of intense exercise followed by short periods of rest. Typical HIIT workouts last around 20-30 minutes or a little longer (as they are very intense and for much longer durations would be a great challenge). The great thing about HIIT is that you can get a lot done in a short amount of time - great for anyone with time!
-Another benefit of HIIT is the afterburn effect – which can be even greater than strength training. This means your metabolic rate stays much higher for hours following a HIIT workout, making it a fantastic calorie burner.
Bottom line: -if your goal is weight loss, a combination of cardio, strength training, and a HIIT session can help burn some calories while leading to various fitness gains. It's also better to mix up our exercises to prevent boredom, so having a variety of styles in your program is a great idea.
Maintain weight...
-If your goal is to stay around your current weight, regular exercise will be important for improving your overall health by helping you maintain an energy balance for weight maintenance.
-The UK's exercise recommendations are as follows: -do at least 150 minutes of moderate-intensity activity each week (moderate intensity means you should feel a little out of breath, your heart rate should be up and you can keep a conversation but not sing a song). ). The recommendation is to spread your 150 minutes of exercise over at least 4/5 days - so aiming for 30 minutes 5 days a week is a great goal. It is also recommended to include at least 2 strength training sessions per week for good overall health. If you feel you are not up to it then seek professional help to understand better.
-Doing moderate-intensity cardio such as walking, swimming, or jogging for 30 minutes two to three times a week, along with two 30-minute strength-based sessions such as weight training, activity physical activity, or weight lifting, will generally help you reach the recommended health guideline. However, if you have a specific fitness goal, such as increasing strength or improving cardiovascular fitness, then adjust your exercise routine to reflect this, placing more emphasis on weight training or higher-intensity cardio. When it comes to weight maintenance, it's all about keeping calories out equal to calories in – so keep in mind, that the more you exercise, the more calories you'll need to eat to avoid weight loss when you don't intend to.
-Just a note! Any type of exercise that gets you moving more and gets your blood pumping is great for your overall health, but the most important thing is to choose an activity you enjoy doing. If you find something you really like, then you're much more likely to stick with it, and the key to successful weight maintenance is to be consistently active – how you do that is up to you!
-Gain weight- To gain weight, you need to be in a calorie surplus, so doing hours and hours of cardio could be counterproductive. That being said, some cardio is important for our overall good health. It's good to include walking or cycling (if you enjoy it) – meeting the physical activity guidelines for general health (150 minutes a week) is suitable for everyone – even if you're trying to gain weight.
-Additionally, if you want to increase the number on the scale, your main focus should be strength training. Many people aiming to gain weight, want to build muscle first - so lifting weights is the answer. It's important to follow an appropriate training program that suits your needs and likely you'll need the advice of a professional help to make sure you're on track to achieve your goals. If you enjoy running or high-impact HIIT, for example, it's still good to continue these forms of exercise to help increase your fitness levels, but you'll need to increase your calorie intake to compensate for the extra calories burned to avoid weight loss.
-Summary: -In the end, all exercise is good because it's about moving your body more. Whether your goal is to lose, gain, or maintain, the key is to choose a form of exercise that you enjoy doing—because that's the one you're likely to stick with! That said, prioritising certain types of activity can be helpful if you have a specific goal in mind, so keep that in mind when setting your training goals.
