for a weekly dose of healthy physical activity, which we believe will promote good health and a healthy weight, is that you cash in 150 minutes of moderate exercise (activity, which is aerobic) spread over a minimum of 5 days a week.
This formula can of course be played around with to match your needs, preferences and time. Continue reading …
Dear Dr. Mo:Is it true that most people are to extent lactose intolerant? Does dairy long term slows ones’ metabolism or truly have a power to boost it? Would you recommend substitutes for dairy for those people with lactose intolerance?
Dear reader: I’ve been drinking milk my whole life – I grew up on it, as was the case with many other kids and as it is the case today. Kids need milk to grow, that’s for sure.
Adults? As with most things, there are benefits and there are risks.
So what’s good in milk and other dairy?
It’s a good and relatively inexpensive source of protein, calcium and vitamin D. Vitamin D does not really naturally occur in milk but in most countries, milk is fortified with it so you find it there. Continue reading …
Dear Dr. Mo: Why does weight fluctuate during the course of a day? Normally my weight is lower early in the morning than it is at night.
Dear reader: The most common reason for such daily weight fluctuations is so called “water weight”.
Water influences our weight
What does “water weight” mean?
You retain some water during the day and this is reflected in changes in your scaled weight within 24-hour periods. These changes are not drastic and are usually anywhere between a few hundred grams to about 2 kilograms (a few pounds).
Now to be clear, these gains are certainly not in fat – to gain so much fat in a day (say about 2 kilos) one would have to consume about 14 000 to 15 000 calories, which is borderline impossible and probably not even survivable. Continue reading …
Dear Dr. Mo:How important is breakfast for my health? Should I skip it if I want to lose some weight? I see some of my friends do this.
Dear reader: To answer simply – breakfast is the most important meal of the day and you should never skip it.
That said; let me quickly give a few important reasons for this.
Make it a healthy choice
Fist and foremost, if you want to lose some weight or just maintain the one you have (especially if it is a healthy one and feels good to you) eating breakfast every morning is the way to go.
I’ve spoken to people whose strategy was to skip breakfast thinking they would reduce their daily amount of calories – you are guessing already – they have failed at that. The reason such a strategy doesn’t work is because without a proper breakfast, you become very hungry by lunch time and not only that but you drive your body into energy conservation mode in which calories are being conserved and stored rather than spent and where your metabolism slows down – all of which is bad news for weight loss. Continue reading …
Dear Dr. Mo: I want to know some basic facts about alcohol and what it does to me when I drink. Is there a safe amount that’s actually good for health?
Don’t drink and drive!
Dear reader: Sometimes you might hear from a doctor that moderate alcohol consumption is good for health.
The peril lies in the word “moderate” for it is arbitrary; it is not the same for everyone and one could easily slip from moderation to amounts that are not at all useful to health. We could certainly argue if alcohol is useful in any amount because while it may be beneficial to one part of the body, it is damaging to another.
We don’t really need alcohol as far as maintaining our health is concerned so if you’ve never drank, don’t start as risks outweigh potential benefits.
Dear Dr. Mo:How much water do I really need to stay hydrated and healthy?
Dear reader: This is the time of year where common colds are indeed common and when you will often hear that advice to drink lots of fluid, usually herbal teas or water. Of course, water is essential to your health but the needs for water vary from person to person and many factors may influence that, like for example your health condition, your daily activities, where you live, your age, metabolic rate etc.
Water means health!
Water is our main constituent – it makes up about 60% of our body mass. We need water to maintain normal functions: we throw out waste matter dissolved in water, water participates in digestion of food, it carries nutrients to cells, we use water to show emotions when we cry etc.
Water also helps to regulate body temperature through perspiration (sweating).
When water is insufficient we dehydrate. Dehydration is a state in which our cells don’t have enough water to function normally. Even a mild dehydration could cause fatigue because when tissues lose water, enzymes are slowing down their functions and energy production drops.
A simple way to see the link between health and water is to observe what happens when we age. As we age, the water content of our bodies is decreasing steadily and while a newborn is 80% water, in an adult this ratio is at 60% and it keeps on decreasing as years go by. Continue reading …
Dear Dr. Mo:What is the link between being overweight and developing Type 2 diabetes? Can diabetes be prevented or cured somehow?
Dear reader: First of all it is worth pointing out that diabetes is a chronic condition. For most types (except gestational type) this chronicity means that once it occurs, it stays for life – this is not a disease we can effectively cure with our present knowledge but we can quite successfully manage it.
Before I go into your question, let me first explain the diabetes landscape and basic mechanisms behind it as Type 2 is not the only game in town.
Diabetes occurs either when the pancreas no longer produces enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar.
The danger of diabetes lies in a condition called Hyperglycaemia – raised blood sugar level – which is a common result of uncontrolled/undiagnosed diabetes, which over time causes serious damage to the body, especially to blood vessels and nerves.
Food choices affect our health
Diabetes has its types and these differ in both the ways they start and the ways in which we manage them.
Type 1 Diabetes
This type had previously been known as insulin-dependent, juvenile or childhood-onset diabetes. Here, our pancreas gland becomes deficient in insulin production and there is simply no longer enough of it to properly regulate our blood sugar levels. Management requires daily administration of insulin and this type cannot be prevented with our current understanding as the cause is not known although we do think it is due to the self-inflicting damage to pancreas (process called “auto immune response”). Continue reading …
Dear Dr. Mo: I am looking into some weight loss programs and I am trying to work out my strategy to come back to my healthy weight. My work sometimes requires giving up on sleep and I tend to be too tired too often. Should I also consider better sleep as part of my weight loss strategy?
Dear reader: What an insightful question! Many of the dieting programs focus heavily on dietary habits and the types of foods we eat, when we eat them and how much. This is rightly so because to attain and maintain a healthy weight, we require a careful selection of healthful foods and a balanced way to eat them. We should also be mindful of our calorie total– don’t go below 1200 calories a day to avoid driving your body into starvation mode.
Sleep is a big part of your healthy weight
Dieting programs also focus on exercise, again rightly so because you need a way to burn through a few hundred calories a day in order to lose about 500 grams a week – which is the pace I’d recommend. If you cut out 500 calories a day, every day, you’ll be losing about 500 grams of weight a week.
What most dieting programs don’t talk about, and I think they should, is a major component of our health – sleep.
If we don’t sleep well and don’t get enough of it, our health suffers and it becomes increasingly difficult to curb the appetite and control our weight. Being overweight deteriorates our health in both the short and the long run.
Disrupted sleep patterns disrupt the circadian rhythm and increase sleep deprivation, which in turn increases the hunger hormone ghrelin.
There are two of these hormones that regulate our appetite and feelings of hunger and fullness – leptin and ghrelin – and both are directly affected by how much sleep time we give ourselves. Continue reading …
Dear readers: After receiving many of your questions related to weight loss, diet and healthy eating, I have realized that there are several misconceptions about dieting, which are bound to affect your diet plans. I think now is the good time to talk about some of the most common advice, which you will hear the minute you announce that you’ve decided to lose some weight or to change your diet habits. I am not saying that all these are completely devoid of truth, but even with a grain of truth in it, a proper interpretation is in order.
One of the first things you’ll probably hear is that you shouldn’t eat after 6 pm or 7 pm or 8pm, or generally in the evening and at night.
Dieting is riddled with myths and fads
Of course, there is no magical cut off time after which you must not eat or else…
What matters in your weight loss plan are your total calories you eat and not really when you do it. What’s true here is that most of us tend to eat more calories in the evening times during dinner or snacking after dinner. In this regard, it makes sense to limit the calories at night if you are one of those who eat more later in the day.
The next word of advice you’re likely to hear is that “eat smaller but more often” myth.
Just because some people eat like this naturally, and stay thin, doesn’t make it a rule for everyone. People who naturally eat like this tend to answer their body’s call and not some strict timing and schedule. Do not eat on the clock but rather listen to the signals the body sends. Eat when you are hungry and don’t wait for a specific time because then you might be too hungry and overeat.
Normally, whichever way works for you, be mindful of the calories to avoid eating too many. Continue reading …
In today’s fast-track world we certainly need a few tricks up our sleeve to be able to stand our ground when eating is concerned and not give in to many calorie dense food pleasures, which end up adding tons of calories to our daily intake increasing our weight and chances for long term health problems like heart disease, Type 2 diabetes and stroke.
Water is life and we are all told this repeatedly but it is also a good way to help you lose 2 – 3 kilos in 6 months! That’s what the research shows and what all of us can try – simply switch from other beverages (sodas, alcohol etc.) you drink each day to water and you will see the results. This trick of course works only if your other eating habits do not compensate for the calories you are saving by drinking water. This also works with calorie free beverages but since some studies have linked these beverages to a paradoxical weight gains and increase in triglycerides, it is best and certainly healthiest to stick to water. Continue reading …
Dear Dr. Mo: I’m worried about my cholesterol levels and I am thinking of ways to avoid foods that will keep on raising it. What to do to bring my cholesterol down?
Dear reader: Following a healthy diet usually brings up the question of which foods to avoid. The follow up thought in our heads leads us to figuring out which foods could raise our cholesterol levels and add kilograms.
Normally, you’d want to avoid too much saturated fats from meat, full fat-dairy products (cheese, high fat milk) and trans fats found in many processed foods like pastries, processed cheese like the ones in a fast-food burger, cakes, cookies, biscuits, creams, candy etc. Even your favorite chips or pretzels are packed with trans fats (these hide behind tech terms like hydrogenated plant-based fat or palm fat so don’t be fooled).
Go nuts – it will regulate your cholesterol
These foods hurt our bodies not just by raising cholesterol levels (mostly the ‘bad’ one – LDL) but by exposing our cells to un-natural compounds, which we were simply not designed to handle.
In response, our systems are stressed out and over time, chain biochemical reactions lead to cancers, heart disease, strokes, diabetes, tons of autoimmune diseases, genetic alterations etc.
The list of unhealthful foods would be far too long. Here’s a hint – those advertised the most are usually suspicious.
Instead, and further to my previous post, I will list 8 foods (and functional foods), which strongly help to regulate your cholesterol level and have appropriate ratio of HDL (the ‘good’ one) Vs. LDL (the ‘bad’ one).
Of course, for some people, diet alone is not enough to bring cholesterol under control in which case your doctor may start you on some medication to help you reach desired levels but even in these cases, proper diet is of large significance for success and long term health. Continue reading …
Dear Dr. Mo:I wish to lose some weight and I know fiber is important part of a good weight-loss plan. My diet so far has not been very healthy and I am trying to improve it. Which foods do you suggest as a good source of fiber?
Dear reader: Nutritional super foods, rich in fiber, antioxidants, vitamins, minerals and other health preserving compounds are all around us. And yet, we succumb to advertising and our own cravings for sugars, greasy junk food and the simple fact that fast food is easier to acquire, it’s more readily available and in truth, it is often cheaper.
Colorful salads are a sure shot when it comes to fiber-rich food
The first step is to become aware of these things and understand that in the 21st century, eating healthy presents a real challenge and asks for will power.
The magic word in today’s healthy diet which attains and maintains a healthy weight and good shape is, planning.
I say that in any weight loss plan, a strategic goal has to be Attain and Maintain.
To Attain and Maintain, you need proper tools, one of which is dietary fiber. Fiber absolutely has to be on your daily menu – it not only helps in weight loss by keeping you fuller for longer and by regulating your bowel movement, it helps regulate cholesterol levels and ratios in the blood, preventing both weight gain and heart disease, Type 2 diabetes etc.
To help in your planning, here are some fiber-rich (super)foods you could include in your everyday meals: Continue reading …
Dear Dr. Mo: I am currently on a weight loss diet – I am trying to make it a healthy one. I’ve heard lots about carbs and fat but what about protein?
Dear reader: Very often, while trying to lose some weight, people obsess around planning their carbs, counting calories, avoiding fats and forget about a very important part of every healthy diet – protein.
Amino acids are the building blocks of proteins and they are not just an essential ingredient for a healthy weight loss, they are also essential for our bodies serving as building material for growth and repair and as a fuel source in times of need.
Turkey meet is high in protein and low in calories
Without protein in your diet, you run a risk of overeating, which, coupled with eating fast is one of the leading causes of weight gain and obesity.
If you overeat on a high-fat, low-protein diet, weight gains may be slower to show but you will be gaining more fat and you will be losing more muscle down the road.The weight as such needs to be considered in a broader perspective, beyond just the BMI (Body Mass Index) or the number on the scale – it is what makes up your total weight that counts the most – whether it is fat or lean muscle; and without protein in your diet, you will be leaning towards more fat and less muscle.
Whether or not you are trying to lose weight, remember that 10 – 35 % of your daily food intake should be lean protein. For men, this comes up to about 56 grams of protein every day and for women, 46 grams to avoid deficiency. Athletes, pregnant women and children may require more, to satisfy their increased demands for building blocks. Continue reading …
Dear Dr. Mo:What are some of the strategies to loose weight in a healthy way? I am not looking for instant results but something long term.
Dear reader: Losing weight and maintaining a healthy weight is no easy task these days. We live fast, eat fast and when weight is concerned – most people want to lose it fast, which is not a healthy way to go about it.
A few facts first:
Eat slowly and limit your portions
Our digestive system has several ways in which it talks to the brain to crank our appetite up or down. This conversation is a continuous process and it involves hormones made in the gut and by the cells that store fat, and it also involves nerve signals, especially the vagus nerve, which runs from the digestive system to the brain.
There’s a hormone called Ghrelin, which gets dispatched from the stomach into the blood to go to the brain and flick the hunger switch on – this is how we start to feel hungry. We respond by eating a meal and during this process our stomach and intestine produce hormones called Leptin and Cholesystokinin to tell the brain to start feeling full.
Vagus nerve is also involved as there are stretch receptors in the stomach, which register the stretch as the stomach fills with food and/or liquids. The stretch signals also tell the brain to feel full.
