Why do people struggle to lose body fat?

Scam? There's a bit of a myth that all low fat and zero fat is high in sugar. Like everything, it depends on product and even brand. My experience of natural greek yogurts is there's very little in the sugar content.

I think you have to check labels, but I find "No added sugar" more of a con job more often, and then all the "protein" labels that have appeared. In a lot of cases not much difference from the standard product.

Macros are protein, fats and carbs- not sugar. I look at it from that prospective rather than sugar on its own. The narrative for decades is that fat = bad. No it is not.

You have essental fats and proteins. You do not have essential carbs and sugar but does not mean you exclude carbs and sugar. Just learn about the macros and understand it and take it from there.

The 'No added sugar' is part of the same 'low fat/no fat' narrative.Of course 'No added suger' means just that. It does not mean there is no suger. Usually means there is TBH. It is a word play.

Sugar is everywhere and is not the necessarily the evil which I think you are hoping I am inferring. I don't have a sweet tooth and never been one to add sugar or even eat sweets growing up. Excess sugar sure like any excess is bad. I eat a lot of fruit- packed with sugar.

people can't grasp serving sizes (and the fact that they're deliberately misleading)

'healthy' cereal, only 110 calories per 25g serving, but that serving size hardly covers the arse of the bowl, and doesn't take into account the milk going with it.
'healthy' olive or coconut oil in cooking, 120 cals per tablespoon.

get a small digital scale, weigh everything, and once your mind is finished being blown - reap results.
Its not magic, it just needs proper attention.

If you are referring to me then you have misconstrued my posts. I specifically mentioned it was about rebalancing the ratio of macros (fats, carbs and protein).

Cut down on the excess carbs (not exclude) because that is where most people overload on calories and substitute it better foods like you did- with vegetables. TBH it is downright impossible to completely exclude carbs anyway. I significantly cut down and then started to reintroduce complex carbs after a couple of months once I had researched more. I love my toast and marmite too much.

You don’t hear of people piling on the weight gorging on tuna and turkey meat in front of the TV. Crisps, biscuits, bread yes but not protein or fats.

Excluding entire food groups is a crash diet and no good in the long run. It is merely another form of calorie deficit but with a fancy marketing gimmick.

Great going with the weight loss.

Some claims of fasting are indeed questionable. However, it does increase insulin sensitivity. It increases fat loss because of obvious reasons. It decreases inflammation and can improve some skin conditions.

The 3 day fasting claim is mostly BS in my opinion and it can be dangerous, supplementation of electrolytes is critical to maintain homeostasis. And his point about cleansing the body doesn't make sense to me. A healthy liver does that anyway, I'm not aware of any type of cleansing pathway that results from fasting, except autophagy. But that pathway isn't well understood yet in humans. If he's talking about his colon then laxatives would achieve similar results without the fasting

And being overweight/obese is? Every time you put food in your mouth, your body spikes insulin, do this too often and it leads to insulin resistance in your body's cells, resulting in a decrease in the cell's efficiency to produce energy. There is a direct correlation between the western obsession with three meals a day (plus snacks) in a high carb diet and the ever increasing incidence of type 2 diabetes and obesity in the general population.

As for myself and my motivation to lose weight, I had an ultrasound scan on my abdomen earlier this year that showed I had a massively fatty liver. Long term, this would cause cirrhosis of that organ and kill it and by extension, me. So that was the kick I needed to address my diet and lose the weight I'd carried not only on my waist but in sub visceral fatty deposits like on my liver. For the first time since my early 20's, I now have a waistline, I can see my abs and I don't see a protruding belly when I look down. Being able to average 35kph for 3-4 hours on a road bike at my age (51) speaks volumes for my fitness. As I said earlier, my diet consists of huge helpings of fresh vegetables and small/medium amounts of "good" protein sources like salmon. So I know I'm eating better than most, even if my feeding window is restricted to one hour a day. Our ancient ancestors could go days if not weeks between meals when relying on their hunting skills (joke here - "did you know the word "vegetarian" was formed in stone age times?.. It means "bad hunter"!!). I'm sure they weren't obsessed with getting 3-4 meals each and every day!

Have you read the studies that indicate that a 24 hour fast induces stem cells to grow in your intestines to repair damage and that a three day fast extends this stem cell production to all of the body to repair/renew tissues? Yes most of the research has been based on animal studies but there is a growing body of evidence from human studies, which while not conclusive as yet, show similar results to those obtain in the animal tests.

As for the "cleansing" of the Colon, are you aware of SIBO and Candida that occur in the intestines? The first is small intestine bacterial overgrowth wherein bacteria that should be in your large intestine grow up into your small intestine causing serious digestive problems. Candida is a bacteria that is normally kept in check in your gut but an overgrowth can also lead to intestinal issues. A three days water fast deprives these organisms of their food source and they get flushed out of the colon naturally. If you drink enough water, why on earth would you use a laxative?

partyguinness · 16-12-2020 06:16PM

Any diet or product that has words like 'cleansing' or 'detox' should be banished to the depths of hell.

Alf Veedersane · 16-12-2020 06:21PM

Calorie-dense food is tasty. People like that.
Discipline is hard. People don't like that.

Also, people eat with their eyes -> full plates

Yeah or the "Only 95calories*" in big bold writing
(per 1/4 serving)

I use a digital scale. It is a ball ache to begin but once you have done it once and generally stick to the same diet it's grand.

SortingYouOut · 16-12-2020 06:24PM

Some people have a real issue with insulin resistance that can affect their hunger regulation and energy. High insulin also dampens your fat burning mechanisms but it's mainly down to Cals in/Cals out. The insulin issue can just result in over eating.

Fasting is immense for your health. I agree with you that this whole idea if three meals a day is a very new concept and definitely doing damage to our health due to insulin resistance and us not allowing our body to truly rest. Fasting has been proven to induce autophagy, which is crazy. We can flush out precancerous cells and repair damaged ones by fasting for a day or two every month.

From a running perspective you should try mixing it up a bit perhaps increase the mileage or the surface. If you keep running essentially the same distance all the time your body will just get used to it and your gains will grind to a halt. Just bear it in mind.

So much information to absorb from this - thanks to everyone who's responded.

I'm not cycling these days so the only cardio I'm doing is the treadmill but primarily focused on lifting weights for now.

I was 80kg in October 2018 but since taking a max dose of anti depressants, which is rarely prescribed, I'm now 99/100kg. I mentioned this to my medical team but they said my weight gain has nothing to do with the medication.

I go the gym daily and I cycle/walk everywhere. I'm 33 and only in the last year or so I've been eating all this food. I don't smoke or even drink.
My mind is constantly absorbed with thoughts of food and how to lose weight but nothing budges on the scales.

Maybe it is binge eating. I could easily eat beyond 6000 calories. Sometimes I feel like a bottomless pit. I eat without thinking.

So, I'm going to try and do what others have suggested here and try restrict my calorie intake and enjoy the hunger. I'll also try not to buy the chocolate, jellies and bring them home.

I'm not physically inactive. I just battle terribly with food.

Binge eating is my problem too. Keto took away my cravings and urges for sugar. People think of sugar cravings as eating sweets etc. but any carbohydrate is scratching that itch. If you're willing to put up with a week or two of mood swings to begin with, you'll open up a whole new world with keto. Our notion of correct diet is incorrect and the food pyramid is still used by the HSE today, even though the mind behind it, Ancel Keys, has been proven wrong by numerous physiologists and others smarter than I could ever dream.

The problem you have is no different than a smoker or alcoholic but your vice is glucose. If you want to take away that want for food, you need to cut the sugar-insulin-crash cycle. You're eating carbs, insulin spikes too high and dips your sugar too low so you end up hungry again due to the blocking effect insulin has on your hunger hormone. You eat more then and the sugar spike brings your energy back to how it should but again, insulin comes along and crashes you to begin the cycle again. Sugar is the root of your problems and I see myself in what you've been saying.

You're well able to get over this man and feel free to PM me for anything you need info wise. I'm currently on my journey, 2 months in and 2 stone down. After the first two weeks, it's a walk in the park.

You'll get a lot of people saying it's all about calories in and calories out, which is of course the base of it all but they don't take into account the factors that make you take in more calories than you should. Food addiction is very real and I feel your pain. Sugar and fast food should be treated just like tobacco, it's disgusting what's happening to people.

I'm am increasing the speed by 0.1KM each week. I find that transition to be challenging. I started at 8Kph and 16 stone, then 8.5, then 9, then 9.5. I found 9.5 to be tough at the time, so, it was at that point that I increased the pace in smaller increments.

I've steadily lost 2lbs a week and I suspect I would have lost 2lbs if I'd have kept at any pace. The increase in pace is save me time, not because it is not working. I burn exactly the same calories at 9.5kph as I do at 10Kph, it just takes more time to do.

Funnily enough, I've found the change from 9.9 to 10kph to be the hardest. My wife thinks this is because 10kph is probably near my limit.

I have 1 more stone to lose, then I'll cut down on the mileage.

While I've exercised regularly for years (running/cycling 4-5 times a week followed by a half hour of weights), I just couldn't get my weight below 96kgs. I'm 5'10, (but with a 44 inch chest and muscular) but at that weight, I was "obese" according to the catch all BMI measurement, even though I could cycle 100kms in 3 and a half hours. However this year, with working from home due to Covid, I could watch what I eat more closely (no more chips and junk in the staff canteen and cakes/biscuits/chocolate at night), I started on the intermittent fasting regimen for 4 months from April this year (eat my meals from 4pm to 8pm only and all home cooked natural and unprocessed food) and my weight fell to 88kgs. I've now moved to OMAD which is one meal a day, albeit eating a large plate of salad at 5pm, followed by steak/salmon/eggs with a large plate of vegetables at 5.30pm and a "treat" of either a plate of fruit or nuts at 6pm. My weight has now dropped to 84kgs. I feel so much better, alert and full of energy than I did when eating crap food. The added bonus is that now that I'm 12kgs lighter, my speed on the bike has increased to an average of 35kph as I'm not lugging round the equivalent of 12 bags of sugar with me anymore.

So exercise as much as you want but if you're eating a crap diet, you will struggle to shift the excess weight. I'd recommend you try intermittent fasting for a start, i.e. fast for 16 hours and eat your meals in an 8 hour window. It's not that hard as you sleep for 7-8 hours a night anyway and so all you have to do is skip breakfast and then eat lunch and dinner between midday and 8pm. The benefit of this is not only giving your digestive system time to "rest" between eating, but it will lower insulin resistance which will stop you craving sugary foods and also increase the hormone Leptin which stops you feeling hungry. I go 23 hours a day without eating (but I drink a lot of water) and it doesn't bother me at all. I can exercise and still feel full of energy as my metabolism has shifted from burning glucose to burning fat which is a more sustainable fuel source for the body (plus it helps shift those stubborn kilos).

And for the piece de resistance, once a month I do a 3 day water only fast to clean out my system of toxins. Trust me, you'd be shocked at the crap (excuse the pun) that your body ejects on a water fast even if your diet is good. Once I keep active, I don't miss food at all for the 3 days. The downside is insomnia for some strange reason but the upside is that when you start eating again after the three days, simple foods like tomatoes and cucumber taste delicious!

I believe in each to their own and I'm not the type to push faddy diets on anyone but intermittent fasting and OMAD has helped me shift weight that years of exercising couldn't. The healthier diet of fresh and unprocessed food has made me feel years younger.

Not directed at me but in my experience, fasting has shown me that I've been clouding my brain with constant meals my whole life. After a fast, my mental clarit is through the roof and I'm very relaxed. Anxiety gone and mood lifted.

Excess carbs rarely turn to fat. It's not efficient to do that.

And whether the body burns fat stores has nothing to so with the macro breakup of your food intake.

You can eat almost 100% carbs and burn body fat store.
You could also eat 0% fat and not touch body fat.

I'm not disagreeing with you. I did say that calories in/out is the base of it all. People jump straight into counting calories only and don't address the reason for overconsumption. Someone with insulin resistance will more likely have better success eating 2000 Cals with a very limited amount of sugar within that compared to 2000 Cals with a load of starchy carbs within that. They'll reduce their cravings and potential for failure. On top of that, if they limit their window of eating, it'll have a positive effect on insulin too which all helps.

No I am now 10st 4/5lbs. I am only repeating the results from my last assessment. It was carried out by a published sports scientist who also works with a number of premiership clubs carrying out similar assessments on Premierhsip footballers pre season. First assessment was in February and second end of July. In fact, at the July assessment I was given a strict running progreamme and I have lost weight since then. Still a bit to go but off season now so not too bothered. I'll have to check the official name of the method used.

Obviously from where you are sitting you are well able to carry out your own assessment on my body composition...;)

FlubberJones · 17-12-2020 10:48AM

I'm 51 and weigh in at around 74 to 75kg (I weigh daily) I have some decent muscle (my own opinion) and carry weight on my stomach . I eat well, I train a LOT, weights in the gym and some cardio (a little) and in fairness I don't p1ss about in the gym either. I work hard as I have the mentality that I have made the effort to get up at 6 to go I should make it worth while....

But to get to the point in question, I hold steady a good chunk of fat on my stomach because I like to drink, I love a good beer and enjoy either GnT or Jameson and ginger.

I have long since realised this is why I don't lose too much body fat, when you have actually identified why you don't you learn to accept it or be miserable and stop the things you enjoy. (mmmm... beer)

So if you consume excess calories in the form of carbs over a period of time it does not turn to fat or rarely? So how do people get fat bearing in mind most people eat excess calories in the form of carbs? I am genuinely curious as that flies in the face of accepted nutritional dogma.

Mellor wrote: »

Well yes it does. What you consume on a daily basis dicates how the body processess and taps into its energy requriements. Whether or not the body starts to burn fat will depend on what you eat. If you eat 0% carbs for a week and just proteins and fats guaranteed you will lose fat (allowing also for the excess water lost through lack of carbs).

What you eat and how the body processes fat are not mutually exclusive.

Mellor wrote: »

That is a somewhat curious statement.

If you eat 100% carbs but not meet your daily calorie intake then of course the body will burn fat.

Consuming 0% fat and not touch body fat? There is no correlation between the consumption of fat and body fat if you are not exceeding your daily BMR.

If you were to eat 100% carbs you would hit your daily calorie intake pretty quickly. That is not sustainable or healthy. Also it is unrealistic or the reality of most people's everyday life and eating habits.

Nobody eats 100% carbs or 0% fat on a daily basis. The OP wants practical advice.
