To really understand how to lose weight you need to learn a little bit about the human body, the mind and nutrition.

Weight loss really is not a complex task – you really do just need to eat less and exercise more. The real challenge is overcoming the mind to control your appetite and combat lethargy.

Here we cover the main topics on weight loss. First we look at dieting and attempt to dispel a few myths and explain that although it is difficult to lose weight by dieting alone, it is certainly possible.

We also look at the role of human biology in weight loss. We also look briefly at “spot reduction”, which is another classic myth of losing weight.


After the information on how to lose weight we review some weight loss books. All of these books have been hand-picked and individually reviewed – they all provide a healthy and sustainable way to lose weight and get fit.

Finally we provide what is hoped to be some motivational advice and then one solution for tackling weight loss, i.e. adopting “SMART” plan.

If you are not sure whether or not you are overweight then you should use our BMI calculator. If you have any questions or need any guidance then please do not hesitate to ask below. There is also a list of resources and references to allow you to learn more on each topic discussed.

Understanding Weight Loss

Combining regular exercise with a healthy diet really is the best way to lose weight, however, often people are unable to exercise on a regular basis for various reasons. So if you are not able to exercise you have to adopt a healthy weight loss diet plan to help you to lose weight and then manage your weight.

Important note: The goal of a weight loss plan is to lose fat and ideally become fitter at the same time. If you are only restricting calories then it is likely that you will lose muscle tissue as well as fat. While this will still record as “weight loss” it is not what you should be aiming for. Muscle is healthy, fat is not.

To lose weight all we need to do is ensure that our daily calorie intake is less than our daily calorie requirements. So why is exercise thought to be so important for weight loss? Regular exercise makes this easier for four main reasons.

How Exercise Helps You To Lose Fat

  1. It increases the amount of calories you burn each day
  2. It increases your metabolism as your body builds new muscle tissue
  3. It helps to manage appetite by releasing hormones that suppress hunger
  4. It helps to use up glycogen reserves which triggers the fat burning hormone called glucagon.

So if you cannot exercise you are missing out on a huge advantage when it comes to weight loss. However, it is still possible to lose weight.

Why Fat Loss Is Your Goal

Everyone asks “how do I lose weight?” but the real question should be “how do I lose body fat while maintaining lean muscle tissue?“. A healthy body is lean and muscular – muscles give us our shape and tone.

Muscles are also vital for good health. Not only do they make us stronger and fitter, they also help keep metabolism raised. Muscle tissue is very “hungry”, it needs proteins and carbohydrates for growth, repair and function, and needs much more energy than fat tissue.

Another way to explain it is that muscles are the body’s engines, fat cells are the fuel tanks. When someone wants to “lose weight”, they actually want to lose fat. Understanding this helps to explain why very low-calorie diets can be counter-productive in the long-term.

The Problem of Very Low Calorie Diets

When people attempt to lose weight with diet alone they generally throw themselves into a low-calorie diet, or sometimes a very low-calorie diet (VLCD) which is defined by being below 1000 calories a day.

Often these diets do not provide the body with enough protein to sustain muscle tissue and so muscle wastage occurs. The body simply breaks downs its own muscle tissue to provide energy for other parts of the body. Fat loss will also occur, but not in isolation.

Biology: The Relationship of Food, Fat Storage and Hormones

To understand why this happens we need to explain a little about how the body stores and then burns fat. There are two hormones at play in the body that control fat storage – insulin and glucagon. Both are triggered by changing levels of glucose in the blood (blood sugar).

When we eat carbohydrates, especially high GI carbs, such as bread, blood sugar levels rise. This increase in blood sugar triggers a release of insulin from the pancreas. The role of insulin is to reduce blood sugar levels, it does this by aiding the uptake of glucose into fat storage (adipose tissue). The glucose is actually converted to glycerol and combined with fatty acids for TAGs (triacylglycerides) and this is what we call “fat”. Prolonged raised levels of sugar in the blood can lead to health problems.

So, in a nutshell, when we consume sugary foods our bodies release insulin that causes that sugar to be stored as fat. Understanding this is key to understanding how diet can help lose weight.

So When Does the Body Decide To Lose Weight?

When glucose levels fall the pancreas then releases glucagon. The role of this hormone is simply the opposite of insulin, it causes blood sugar levels to rise again. Glucose is the prime energy source of the brain which is our prime organ as it controls the functions of all other parts of the body.

So glucagon’s prime objective is to ensure that the brain is supplied with sugar. It does this by breaking down the fat tissue to extract the sugars locked up in the TAGs (glycerol and fatty acids). This is what we call fat burning.

It is not easy to get the body to release glucagon though. You have to allow your blood sugar levels to fall to very low levels. As soon as you eat a sugary food, such as some bread, pasta, high GI vegetable like parsnips and pumpkin, processed breakfast cereals, rice, any junk food (cakes, cookies, donuts), you blood sugar rises and therefore glucagon production stops and insulin takes over, so you quickly go from a fat burning situation back to a fat storing one.

This is why unhealthy diets are so likely to lead to weight gain – most of what is unhealthy is also high on the glycemic index (high GI) which means it causes blood sugar spikes, insulin and fat accumulation. So by limiting high GI foods you can help to lose weight with diet alone.

The Importance of Protein

Protein is important for two reasons:

  1. Without adequate daily protein muscles start to waste away as the amino acids locked within the muscle tissue are used to help with the ongoing repair of vital organs.
  2. When protein is digested the body releases another hormone, PYY, which helps to suppress hunger.

This is another reason why very low-calorie diets are bad – people eating less than 1000 Calories a day to lose weight often fail to consume enough protein, instead just eating their favorite sugary snacks.

This sugar heavy diet not only causes fat to be stored but also the lack of protein causes muscles to waste away and lowers BMR (basal metabolic rate) which determines how much energy is used to maintain the body at rest.

The Role of Exercise

Although it is possible to lose weight through healthy diet alone, as detailed above, it is far easier and quicker to lose weight by combining diet with exercise. But when is the best time to exercise? Is there a best time at all?

One school of thought is that so long as you are active and burn additional calories it does not matter what time you exercise. However, there are other opinions on this, so lets take a look at them.


Many people advocate that the best way to lose weight is to exercise on an empty stomach before a meal. It has long been believed that this fasted exercising will increase metabolism and help lose weight, then eating afterwards will provide the body with essential proteins, carbohydrate and fats to start building healthy new muscle tissue.

However, recent collaborative research carried out by Surrey University and Imperial College London and published in the Journal of Endocrinology suggests that exercise after eating can help people to lose weight more effectively than vice versa.

The research found that exercising after a meal boosts the release of hormones PYY, GLP-1 and PP which then suppress appetite, meaning that you stay full for longer which reduces snacking.

Dr John McAvoy, a GP with a special interest in obesity, said “For exercise to contribute to weight control it should be sustainable over the long-term and enjoyment remains a critical factor to this end.”

As is often the case, the real conclusion is that to lose weight, lifestyle change is required. There really is no quick fix to fitness and health. People that keep healthy remain active throughout their lives and generally socialize with more active people.

One specific hormone that we are currently aware of which affects appetite is the PPY hormone. PPY helps to reduce our appetite when it is in the system. It is created in the body in response to two specific activities; exercise and the digestion of proteins.

Previously it was assumed that the increase of PPY in the body would not last long enough to make exercise after a meal a useful approach to weight loss. However, research has shown that exercise does not result in a reduced calorie consumption. In fact, people who exercise tend to eat more food than the sedentary people!

Ultimately the best advice is to find a healthy sport or pastime that you enjoy and build it into your life so that as time passes exercising becomes part of your daily routine, second nature.

Exercise is Important

Exercise does help you to lose weight and it certainly gets you fit. But you need to ensure you exercise with intensity and do not over eat afterwards. So many people treat themselves to a big dinner or breakfast after exercising in the mistaken belief that they have worked hard enough to deserve it.

This is rarely, if ever, true. Professional swimmers, athletes and bodybuilders consume considerably more calories every day, but they are super-fit and train for several hours each day at a much higher intensity than an overweight and unfit person can manage.

Exercise does have a vital purpose though. Most people who manage to control their weight long-term after losing a lot of weight do so by using exercise. If you are fit and exercise on the regular basis you can get away with a few more eating binges before the weight comes back on.

If you want to lose weight and shed the pounds, then the answer is to eat a healthy well-balanced, portion controlled diet AND do some exercise to get fitter so that you can maintain your healthy weight.

One final point on exercise – it boosts your confidence. Another study recent showed that people feel better about themselves after they exercise. Even when there is no real physical change, self-confidence is improved. This increase in self-esteem caused by exercise leads to more exercise and eventually you become healthier, fitter and slimmer.

Sometimes you have to be really careful how you interpret results of studies. The tabloids reported both of these stories in the most controversial way possible, that is diet does not lead to weight loss, and neither does exercise.

The research is still important as it helps us to understand the dynamics of weight loss, diet and exercise and how our bodies respond to changing conditions. However, as far as the average overweight person is concerned, the same rules apply – exercise more and eat less to lose weight.

The key to losing weight and staying fit and healthy is to make a full lifestyle change which involves eating less, eating a well-balanced diet and getting regular exercise.

Be more active every day, it really will make you fitter and leaner. Combine these weight loss articles with a specialist weight loss plan and you can lose weight even faster!

Weight Loss Depends on You

“A Weight Loss Plan Is Only Ever As Good As The Person Following It”

Many people spend a long time looking for the “perfect” or “best” weight loss solution. And as there are so many products, plans, regimes and systems on the market it often seems logical to assume that there must be a system that cannot fail.

However, every year people do fail to lose weight and get back in shape. Also every year we hear people saying “I have tried everything to lose weight and nothing works”.

So, are all weight loss plans a waste of time, and money? Well, maybe they are, if you are not prepared to put in the effort.

That is why we always say, “A Weight Loss Plan Is Only Ever As Good As The Person Following It“.

You can hire the world’s top nutritionists and fitness instructors to help you meet your weight loss goals, but if you do not put in the effort, if you are not fully committed, then failure is a real possibility.

Alternatively you could follow the simplest of plans, and if you are dedicated and work hard, you will succeed.

When it comes to losing weight and getting back is shape, the only person that can make that change is you. You have to follow the diets, you have to do the exercise, you have to control your appetite and not give in to your cravings in more difficult times emotionally. Only you can do it!

However, saying that, a good plan does provide a solid foundation on which to work. And being part of a weight loss or fitness group can help provide the support and encouragement that you need to help keep you on target.

successful long-term weight loss maintainers share common behavioral strategies, including eating a diet low in fat, frequent self-monitoring of body weight and food intake, and high levels of regular physical activity” (Wing and Hill, 2001)

So if you do decide to follow a weight loss plan, remember, the plan will only work if you do too. Long term weight loss requires constant vigilance. Never stop monitoring and keep food and exercise journals if need be.

The easiest thing in the world is to give up on the plan and revert to your old, unhealthy, sedentary lifestyle and put all the weight back on again. Do not let this happen. Once on the slippery slope to weight gain it is hard to stop.

All of these plans can be very effective. No weight loss plan will work if you are not committed to follow the rules, read all the guidelines and most importantly do the hard work, that is exercising or following a strict diet.

These plans will in the long-term do more than just help you lose a few pounds though (you can learn more about the health benefits of exercise here).

They will teach you how to live a healthier and more fulfilling life. Regular exercise and a healthy diet will literally add years, maybe even decades, to your life. And it will also make those extra years more rewarding as you will remain more active into old age.

We are living in a society today where more people are growing older each year but many of these people are house bound, obese and very inactive. The quality of life for millions of people is well below average.

Anyone who does not take action and strive to become fitter and healthier when they are young, risks crippling health problems later in life. So do yourself a favor and get active and start changing your life today! Still not sure where to start? Check out our 50 ways to live a healthier life.

    Kelly, you definitely haver to stop the pop juice if you want to lose weight. Some milk, in moderation, is OK. Too much will of course stop you from losing weight. A glass a day should be enough.

    oh thanks for the great advice. i have another question is that i love yogurt and i usually get the strawberry one (yoplait) ummm should i switch it to (light yoplait)? thanks

    No, either is OK, but if you are eating several a day then consider Light, or eating fewer.

    According to yoplait.com the original contains 170 CAlories, with 25g sugars and 5% saturated fat. The Light contains 90 Calories, with 10g sugars and 0% saturated fat. So Light is almost half the total calories.

    Hi Kelly, these daily fluctuations in weight is not “weight loss”, it is just the weight of your meals and drinks. You are not losing 3 pounds while you sleep. Just maintain the healthier diet and regular exercise, and weigh yourself once a week, ideally at the same time each week, such as before breakfast on a Monday.

    oh ok thanks for the tips and answers. yes i thought it was pretty weird losing 3 pounds in one night. its not possible. lol or maybe the scale is telling me wrong or something. WHERE CAN I GET A ACCURATE WEIGHT SCALE?

  7. MotleyHealth
    May 3, 2013 at 5:32 pm

    Kelly, the scale may be accurate, but remember, if you drink a pint of water your weight will increase by about 1 pound. After a few meals your weight will increase by several pounds. Just weigh yourself once a week.
