How to Lose Weight Fast: 3 Simple Steps, Based on Science

How to Lose Weight Fast: 3 Simple Steps, Based on Science











There are many ways to lose a lot of weight fast.
However, most of them will make you hungry and unsatisfied.
If you don't have iron willpower, then hunger will cause you to give up on these plans quickly.
The plan outlined here will:
  • Reduce your appetite significantly.
  • Make you lose weight quickly, without hunger.
  • Improve your metabolic health at the same time.
Here is a simple 3-step plan to lose weight fast.

The most important part is to cut back on sugars and starches (carbs).
When you do that, your hunger levels go down and you end up eating much fewer calories (1).
Now instead of burning carbs for energy, your body starts feeding off of stored fat.
Another benefit of cutting carbs is that it lowers insulin levels, causing your kidneys to shed excess sodium and water out of your body. This reduces bloat and unnecessary water weight (2, 3).
It is not uncommon to lose up to 10 pounds (sometimes more) in the first week of eating this way, both body fat and water weight.
This is a graph from a study comparing low-carb and low-fat diets in overweight or obese women (4).

The low-carb group is eating until fullness, while the low-fat group is calorie-restricted and hungry.
Cut the carbs and you will start to eat fewer calories automatically and without hunger (5).
Put simply, cutting carbs puts fat loss on autopilot.
SUMMARYRemoving sugars and starches (carbs) from your diet will reduce your appetite, lower your insulin levels and make you lose weight without hunger.

Each one of your meals should include a protein source, a fat source and low-carb vegetables.
Constructing your meals in this way will automatically bring your carb intake into the recommended range of 20–50 grams per day.

Protein Sources

  • Meat: Beef, chicken, pork, lamb, etc.
  • Fish and Seafood: Salmon, trout, shrimp, etc.
  • Eggs: Whole eggs with the yolk are best.
The importance of eating plenty of protein cannot be overstated.
This has been shown to boost metabolism by 80 to 100 calories per day (678).
High-protein diets can also reduce cravings and obsessive thoughts about food by 60%, reduce the desire for late-night snacking by half, and make you so full that you automatically eat 441 fewer calories per day — just by adding protein to your diet (910).
When it comes to losing weight, protein is the king of nutrients. Period.

Low-Carb Vegetables

  • Broccoli
  • Cauliflower
  • Spinach
  • Tomatoes
  • Kale
  • Brussels sprouts
  • Cabbage
  • Swiss chard
  • Lettuce
  • Cucumber
  • Full list here.
Don’t be afraid to load your plate with these low-carb vegetables. You can eat massive amounts of them without going over 20–50 net carbs per day.
A diet based mostly on meat and vegetables contains all the fiber, vitamins and minerals you need to be healthy.

Fat Sources

  • Olive oil
  • Coconut oil
  • Avocado oil
  • Butter
Eat 2–3 meals per day. If you find yourself hungry in the afternoon, add a 4th meal.
Don’t be afraid of eating fat, as trying to do both low-carb AND low-fat at the same time is a recipe for failure. It will make you feel miserable and abandon the plan.
To see how you can assemble your meals, check out this low-carb meal plan and this list of 101 healthy low-carb recipes.
SUMMARYAssemble each meal out of a protein source, a fat source and low-carb vegetables. This will put you in the 20–50 gram carb range and significantly lower your hunger levels.







You don't need to exercise to lose weight on this plan, but it is recommended.
The best option is to go to the gym 3–4 times a week. Do a warm-up and lift some weights.
If you're new to the gym, ask a trainer for some advice.
By lifting weights, you will burn lots of calories and prevent your metabolism from slowing down, which is a common side effect of losing weight (1112).
Studies on low-carb diets show that you can even gain a bit of muscle while losing significant amounts of body fat (13).
If lifting weights is not an option for you, then doing some cardio workouts like walking, jogging, running, cycling or swimming will suffice.
SUMMARYIt is best to do some sort of resistance training like weight lifting. If that is not an option, cardio workouts are also effective.

You can take one day off per week where you eat more carbs. Many people prefer Saturday.
It is important to stick to healthy carb sources like oats, rice, quinoa, potatoes, sweet potatoes, fruit, etc.
But only this one higher carb day — if you start doing it more often than once per week you're not going to see much success on this plan.
If you must have a cheat meal and eat something unhealthy, then do it on this day.
Be aware that cheat meals or carb refeeds are NOT necessary, but they can boost some fat-burning hormones like leptin and thyroid hormones (1415).
You will gain some weight during your refeed day, but most of it will be water weight and you will lose it again in the next 1–2 days.
SUMMARYHaving one day each week where you eat more carbs is perfectly acceptable, although not necessary.

It is NOT necessary to count calories as long as you keep the carbs very low and stick to protein, fat and low-carb vegetables.
However, if you really want to count them, use this calculator.
Enter your details, and then pick the number from either the "Lose Weight" or the "Lose Weight Fast" section — depending on how fast you want to lose weight.
There are many great tools you can use to track the number of calories you are eating. Here is a list of 5 calorie counters that are free and easy to use.
The main goal of this plan is to keep carbs under 20–50 grams per day and get the rest of your calories from protein and fat.
SUMMARYIt is not necessary to count calories to lose weight on this plan. It is most important to strictly keep your carbs in the 20–50 gram range.







Here are 10 more tips to lose weight even faster:
  1. Eat a high-protein breakfast. Eating a high-protein breakfast has been shown to reduce cravings and calorie intake throughout the day (1617).
  2. Avoid sugary drinks and fruit juice. These are the most fattening things you can put into your body, and avoiding them can help you lose weight (1819).
  3. Drink water a half hour before meals. One study showed that drinking water a half hour before meals increased weight loss by 44% over 3 months (20).
  4. Choose weight loss-friendly foods (see list). Certain foods are very useful for losing fat. Here is a list of the 20 most weight loss-friendly foods on earth.
  5. Eat soluble fiber. Studies show that soluble fibers may reduce fat, especially in the belly area. Fiber supplements like glucomannan can also help (2122).
  6. Drink coffee or tea. If you're a coffee or tea drinker, then drink as much as you want as the caffeine can in them boost your metabolism by 3–11% (232425).
  7. Eat mostly whole, unprocessed foods. Base most of your diet on whole foods. They are healthier, more filling and much less likely to cause overeating.
  8. Eat your food slowly. Fast eaters gain more weight over time. Eating slowly makes you feel more full and boosts weight-reducing hormones (2627).
  9. Weigh yourself every day. Studies show that people who weigh themselves every day are much more likely to lose weight and keep it off for a long time (2829).
  10. Get a good night's sleep, every night. Poor sleep is one of the strongest risk factors for weight gain, so taking care of your sleep is important (30).
SUMMARYIt is most important to stick to the three rules, but there are a few other things you can do to speed things up.

You can expect to lose 5–10 pounds of weight (sometimes more) in the first week, then consistent weight loss after that.
I can personally lose 3–4 pounds per week for a few weeks when I do this strictly.
If you're new to dieting, then things will probably happen quickly. The more weight you have to lose, the faster you will lose it.
For the first few days, you might feel a bit strange. Your body has been burning carbs for all these years, so it can take time for it to get used to burning fat instead.
This is called the "low-carb flu" or “keto flu” and is usually over within a few days. For me it takes three. Adding some extra salt to your diet can help with this.
After the first few days, most people report feeling very good, with even more energy than before.
Despite many decades of anti-fat hysteria, the low-carb diet also improves your health in many other ways:
  • Blood sugar tends to go way down on low-carb diets (31).
  • Triglycerides tend to go down (32).
  • Small, dense LDL (the bad) cholesterol goes down (3334).
  • HDL (the good) cholesterol goes up (35).
  • Blood pressure improves significantly (3637).
  • To top it all off, low-carb diets appear to be just as easy to follow as low-fat diets.
SUMMARYYou can expect to lose a lot of weight, but it depends on the person how quickly it will happen. Low-carb diets also improve your health in many other ways.

If you have a medical condition, talk to your doctor before making changes because this plan can reduce your need for medication.
By reducing carbs and lowering insulin levels, you change the hormonal environment and make your body and brain "want" to lose weight.
This leads to drastically reduced appetite and hunger, eliminating the main reason that most people fail with conventional weight loss methods.
This is proven to make you lose up to 2–3 times as much weight as a typical low-fat, calorie-restricted diet (383940).
Another great benefit for the impatient folks is that the initial drop in water weight can lead to a big difference on the scale as early as the next morning.
Here are a few examples of low-carb meals that are simple, delicious and can be prepared in under 10 minutes: 7 Healthy Low-Carb Meals in 10 Minutes or Less.
On this plan, you can eat good food until you’re full and still lose a ton of fat. Welcome to paradise.

SHAKE IT OFF Protein shakes stop weight loss and make you FAT, experts warn

Protein shakes stop weight loss and make you FAT, experts warn


YOU may see fitness bloggers and PTs chugging down shakes each day but that doesn't mean you should too.
Because scientists believe that daily protein shakes may be causing us to pile on the pounds.








You have them after a session in the gym to help repair the muscles you've worked.
But it turns out that chugging amino acids could have some negative side-effects.
Scientists from the University of Sydney's Charles Perkins Centre have found that too many protein shakes and snacks may reduce our lifespan, make us moodier and lead to weight gain.
Dr Samantha Solon-Biet has been looking into how our food can impact on metabolic health, reproduction, appetite and aging.

High protein diets result in shorter lives

"While diets high in protein and low in carbohydrates were shown to be beneficial for reproductive function, they had detrimental effects for health in mid-late life, and also led to a shortened lifespan," she explained.
"What this new research has shown is that amino acid balance is important—it's best to vary sources of protein to ensure you're getting the best amino acid balance."
When we supplement with BCAAs, that can lead to a high amount of the acids in our blood.
They compete with something called tryptophan for transport to the brain.
We need tryptophan because it helps us to make the "happiness hormone" serotonin.
Not only does serotonin make us happier, but it also helps us to sleep better and reduce appetite.
So if we've got a load of BCAAs pushing stopping that tryptophan from getting to the brain, we'll start underproducing serotonin.

Lack of serotonin results in overeating

"The serotonin decrease caused by excess BCAA intake led to massive overeating in our mice, which became hugely obese and lived shorter lives," explained Professor Stephen Simpson.
Mice were fed double the normal amount of BCAAs, the standard amount, a half or one fifth for life.
Those who were fed double increased their food intake, resulting in obesity and a shorter life.
The conclusion? Get your protein from a wide array of natural sources - not in powdered form.

Eat protein in food form - not powder

Lean meats, fish, eggs soy, hemp and peas all contain protein and amino acids, and come with added benefits like fibre, vitamins and minerals.
It's really important to make sure that you're eating different protein sources in order to get a variety of amino acids.
And as well as protein, eating foods rich in tryptophan is important too.

How to Lose Weight and Keep It Off



In our eat-and-run, massive-portion-sized culture, maintaining a healthy weight can be tough—and losing weight, even tougher. If you’ve tried and failed to lose weight before, you may believe that diets don’t work for you. You’re probably right: some diets don’t work at all and none of them work for everyone—our bodies often respond differently to different foods. But while there’s no easy fix to losing weight, there are plenty of steps you can take to develop a healthier relationship with food, curb emotional triggers to overeating, and achieve lasting weight-loss success.

What’s the best diet for healthy weight loss?

Pick up any diet book and it will claim to hold all the answers to successfully losing all the weight you want—and keeping it off. Some claim the key is to eat less and exercise more, others that low fat is the only way to go, while others prescribe cutting out carbs. So, what should you believe?
The truth is there is no “one size fits all” solution to permanent healthy weight loss. What works for one person may not work for you, since our bodies respond differently to different foods, depending on genetics and other health factors. To find the method of weight loss that’s right for you will likely take time and require patience, commitment, and some experimentation with different foods and diets.
While some people respond well to counting calories or similar restrictive methods, others respond better to having more freedom in planning their weight-loss programs. Being free to simply avoid fried foods or cut back on refined carbs can set them up for success. So, don’t get too discouraged if a diet that worked for somebody else doesn’t work for you. And don’t beat yourself up if a diet proves too restrictive for you to stick with. Ultimately, a diet is only right for you if it’s one you can stick with over time.

Four popular weight loss strategies

 

 1. Cut calories

Some experts believe that successfully managing your weight comes down to a simple equation: If you eat fewer calories than you burn, you lose weight. Sounds easy, right? Then why is losing weight so hard?
  • Weight loss isn’t a linear event over time. When you cut calories, you may drop weight for the first few weeks, for example, and then something changes. You eat the same number of calories but you lose less weight or no weight at all. That’s because when you lose weight you’re losing water and lean tissue as well as fat, your metabolism slows, and your body changes in other ways. So, in order to continue dropping weight each week, you need to continue cutting calories.
  • A calorie isn’t always a calorie. Eating 100 calories of high fructose corn syrup, for example, can have a different effect on your body than eating 100 calories of broccoli. The trick for sustained weight loss is to ditch the foods that are packed with calories but don’t make you feel full (like candy) and replace them with foods that fill you up without being loaded with calories (like vegetables).
  • Many of us don’t always eat simply to satisfy hunger. We also turn to food for comfort or to relieve stress—which can quickly derail any weight loss plan.

 

 2. Cut carbs

A different way of viewing weight loss identifies the problem as not one of consuming too many calories, but rather the way the body accumulates fat after consuming carbohydrates—in particular the role of the hormone insulin. When you eat a meal, carbohydrates from the food enter your bloodstream as glucose. In order to keep your blood sugar levels in check, your body always burns off this glucose before it burns off fat from a meal.
If you eat a carbohydrate-rich meal (lots of pasta, rice, bread, or French fries, for example), your body releases insulin to help with the influx of all this glucose into your blood. As well as regulating blood sugar levels, insulin does two things: It prevents your fat cells from releasing fat for the body to burn as fuel (because its priority is to burn off the glucose) and it creates more fat cells for storing everything that your body can’t burn off. The result is that you gain weight and your body now requires more fuel to burn, so you eat more. Since insulin only burns carbohydrates, you crave carbs and so begins a vicious cycle of consuming carbs and gaining weight. To lose weight, the reasoning goes, you need to break this cycle by reducing carbs.
Most low-carb diets advocate replacing carbs with protein and fat, which could have some negative long-term effects on your health. If you do try a low-carb diet, you can reduce your risks and limit your intake of saturated and trans fats by choosing lean meats, fish and vegetarian sources of protein, low-fat dairy products, and eating plenty of leafy green and non-starchy vegetables.

3. Cut fat

It’s a mainstay of many diets: if you don’t want to get fat, don’t eat fat. Walk down any grocery store aisle and you’ll be bombarded with reduced-fat snacks, dairy, and packaged meals. But while our low-fat options have exploded, so have obesity rates. So, why haven’t low-fat diets worked for more of us?
  1. Not all fat is bad. Healthy or “good” fats can actually help to control your weight, as well as manage your moods and fight fatigue. Unsaturated fats found in avocados, nuts, seeds, soy milk, tofu, and fatty fish can help fill you up, while adding a little tasty olive oil to a plate of vegetables, for example, can make it easier to eat healthy food and improve the overall quality of your diet.
  2. We often make the wrong trade-offs. Many of us make the mistake of swapping fat for the empty calories of sugar and refined carbohydrates. Instead of eating whole-fat yoghurt, for example, we eat low- or no-fat versions that are packed with sugar to make up for the loss of taste. Or we swap our fatty breakfast bacon for a muffin or donut that causes rapid spikes in blood sugar.

4. Follow the Mediterranean diet

The Mediterranean diet emphasizes eating good fats and good carbs along with large quantities of fresh fruits and vegetables, nuts, fish, and olive oil—and only modest amounts of meat and cheese. The Mediterranean diet is more than just about food, though. Regular physical activity and sharing meals with others are also major components.
Whatever weight loss strategy you try, it’s important to stay motivated and avoid common dieting pitfalls, such as emotional eating.

Control emotional eating

We don’t always eat simply to satisfy hunger. All too often, we turn to food when we’re stressed or anxious, which can wreck any diet and pack on the pounds. Do you eat when you’re worried, bored, or lonely? Do you snack in front of the TV at the end of a stressful day? Recognizing your emotional eating triggers can make all the difference in your weight-loss efforts. If you eat when you’re:
Stressed – find healthier ways to calm yourself. Try yoga, meditation, or soaking in a hot bath.
Low on energy – find other mid-afternoon pick-me-ups. Try walking around the block, listening to energizing music, or taking a short nap.
Lonely or bored – reach out to others instead of reaching for the refrigerator. Call a friend who makes you laugh, take your dog for a walk, or go to the library, mall, or park—anywhere there’s people.

Practice mindful eating instead

Avoid distractions while eating. Try not to eat while working, watching TV, or driving. It’s too easy to mindlessly overeat.
Pay attention. Eat slowly, savoring the smells and textures of your food. If your mind wanders, gently return your attention to your food and how it tastes.
Mix things up to focus on the experience of eating. Try using chopsticks rather than a fork, or use your utensils with your non-dominant hand.
Stop eating before you are full. It takes time for the signal to reach your brain that you’ve had enough. Don’t feel obligated to always clean your plate.

Stay motivated

Permanent weight loss requires making healthy changes to your lifestyle and food choices. To stay motivated:
Find a cheering section. Social support means a lot. Programs like Jenny Craig and Weight Watchers use group support to impact weight loss and lifelong healthy eating. Seek out support—whether in the form of family, friends, or a support group—to get the encouragement you need.
Slow and steady wins the race. Losing weight too fast can take a toll on your mind and body, making you feel sluggish, drained, and sick. Aim to lose one to two pounds a week so you’re losing fat rather than water and muscle.
Set goals to keep you motivated. Short-term goals, like wanting to fit into a bikini for the summer, usually don’t work as well as wanting to feel more confident or become healthier for your children’s sakes. When temptation strikes, focus on the benefits you’ll reap from being healthier.
Use tools to track your progress. Smartphone apps, fitness trackers, or simply keeping a journal can help you keep track of the food you eat, the calories you burn, and the weight you lose. Seeing the results in black and white can help you stay motivated.
Get plenty of sleep. Lack of sleep stimulates your appetite so you want more food than normal; at the same time, it stops you feeling satisfied, making you want to keep eating. Sleep deprivation can also affect your motivation, so aim for eight hours of quality sleep a night.

Cut down on sugar and refined carbs

Whether or not you’re specifically aiming to cut carbs, most of us consume unhealthy amounts of sugar and refined carbohydrates such as white bread, pizza dough, pasta, pastries, white flour, white rice, and sweetened breakfast cereals. Replacing refined carbs with their whole-grain counterparts and eliminating candy and desserts is only part of the solution, though. Sugar is hidden in foods as diverse as canned soups and vegetables, pasta sauce, margarine, and many reduced fat foods. Since your body gets all it needs from sugar naturally occurring in food, all this added sugar amounts to nothing but a lot of empty calories and unhealthy spikes in your blood glucose.
