10 tips for successful weight loss

Being overweight or obese can lead to a range of health problems. Although many different "fad" diets are available, a balanced lifestyle and nutritious diet are the key to healthful living and better weight control. According to the Centers for Disease Control and Prevention, around 93.3 million adultsTrusted Source in the United States had obesity in 2015–2016. This number is equivalent to 39.8 percent of the population. Carrying excess body weight can increase the risk of serious health problems, including heart disease, hypertension, and type 2 diabetes. Crash diets are not a sustainable solution, whatever perks their proponents might claim them to have. To both lose weight safely and sustain that weight loss over time, it is essential to make gradual, permanent, and beneficial lifestyle changes. In this article, we provide 10 tips for weight control. MEDICAL NEWS TODAY NEWSLETTER Stay in the know.

Eat varied, colorful, nutritionally dense foods Eat a varied, nutritious diet. Healthful meals and snacks should form the foundation of the human diet. A simple way to create a meal plan is to make sure that each meal consists of 50 percent fruit and vegetables, 25 percent whole grains, and 25 percent protein. Total fiber intake should be 25–30 grams (g) daily. Eliminate trans fats from the diet, and minimize the intake of saturated fats, which has a strong link with the incidence of coronary heart disease. Instead, people can consume monounsaturated fatty acids (MUFA) or polyunsaturated fatty acids (PUFA), which are types of unsaturated fat. The following foods are healthful and often rich in nutrients: fresh fruits and vegetables fish legumes nuts seeds whole grains, such as brown rice and oatmeal Foods to avoid eating include: foods with added oils, butter, and sugar fatty red or processed meats baked goods bagels white bread processed foods In some cases, removing certain foods from the diet might cause a person to become deficient in some necessary vitamins and minerals. A nutritionist, dietitian, or another healthcare professional can advise a person how to get enough nutrients while they are following a weight loss program. 2. Keep a food and weight diary Self-monitoring is a critical factor in successfully losing weight. People can use a paper diary, mobile app, or dedicated website to record every item of food that they consume each day. They can also measure their progress by recording their weight on a weekly basis. Those who can track their success in small increments and identify physical changes are much more likely to stick to a weight loss regimen. People can also keep track of their body mass index (BMI) using a BMI calculator. 3. Engage in regular physical activity and exercise Regular physical activity can help a person lose weight. Regular exercise is vital for both physical and mental health. Increasing the frequency of physical activity in a disciplined and purposeful way is often crucial for successful weight loss. One hour of moderate-intensity activity per day, such as brisk walking, is ideal. If one hour per day is not possible, the Mayo Clinic suggests that a person should aim for a minimum of 150 minutes every week. People who are not usually physically active should slowly increase the amount of exercise that they do and gradually increase its intensity. This approach is the most sustainable way to ensure that regular exercise becomes a part of their lifestyle. In the same way that recording meals can psychologically help with weight loss, people may also benefit from keeping track of their physical activity. Many free mobile apps are available that track a person's calorie balance after they log their food intake and exercise. If the thought of a full workout seems intimidating to someone who is new to exercise, they can begin by doing the following activities to increase their exercise levels: taking the stairs raking leaves walking a dog gardening dancing playing outdoor games parking farther away from a building entrance Individuals who have a low risk of coronary heart disease are unlikely to require medical assessment ahead of starting an exercise regimen. However, prior medical evaluation may be advisable for some people, including those with diabetes. Anyone who is unsure about safe levels of exercise should speak to a healthcare professional. 4. Eliminate liquid calories It is possible to consume hundreds of calories a day by drinking sugar-sweetened soda, tea, juice, or alcohol. These are known as "empty calories" because they provide extra energy content without offering any nutritional benefits. Unless a person is consuming a smoothie to replace a meal, they should aim to stick to water or unsweetened tea and coffee. Adding a splash of fresh lemon or orange to water can provide flavor. Avoid mistaking dehydration for hunger. An individual can often satisfy feelings of hunger between scheduled meal times with a drink of water. 5. Measure servings and control portions Eating too much of any food, even low-calorie vegetables, can result in weight gain. Therefore, people should avoid estimating a serving size or eating food directly from the packet. It is better to use measuring cups and serving size guides. Guessing leads to overestimating and the likelihood of eating a larger-than-necessary portion. The following size comparisons can be useful for monitoring food intake when dining out: three-fourths of a cup is a golf ball one-half of a cup is a tennis ball 1 cup is a baseball 1 ounce (oz) of nuts is a loose handful 1 teaspoon is 1 playing die 1 tablespoon is a thumb tip 3 oz of meat is a deck of cards 1 slice is a DVD These sizes are not exact, but they can help a person moderate their food intake when the correct tools are not available. 6. Eat mindfully Many people benefit from mindful eating, which involves being fully aware of why, how, when, where, and what they eat. Making more healthful food choices is a direct outcome of becoming more in tune with the body. People who practice mindful eating also try to eat more slowly and savor their food, concentrating on the taste. Making a meal last for 20 minutes allows the body to register all of the signals for satiety. It is important to focus on being satisfied after a meal rather than full and to bear in mind that many "all natural" or low-fat foods are not necessarily a healthful choice. People can also consider the following questions regarding their meal choice: Is it good "value" for the calorie cost? Will it provide satiety? Are the ingredients healthful? If it has a label, how much fat and sodium does it contain? 7. Stimulus and cue control Many social and environmental cues might encourage unnecessary eating. For example, some people are more likely to overeat while watching television. Others have trouble passing a bowl of candy to someone else without taking a piece. By being aware of what may trigger the desire to snack on empty calories, people can think of ways to adjust their routine to limit these triggers. 8. Plan ahead Stocking a kitchen with diet-friendly foods and creating structured meal plans will result in more significant weight loss. People looking to lose weight or keep it off should clear their kitchen of processed or junk foods and ensure that they have the ingredients on hand to make simple, healthful meals. Doing this can prevent quick, unplanned, and careless eating. Planning food choices before getting to social events or restaurants might also make the process easier. 9. Seek social support Having social support is a great way to stay motivated. Embracing the support of loved ones is an integral part of a successful weight loss journey. Some people may wish to invite friends or family members to join them, while others might prefer to use social media to share their progress. Other avenues of support may include: a positive social network group or individual counseling exercise clubs or partners employee-assistance programs at work 10. Stay positive Weight loss is a gradual process, and a person may feel discouraged if the pounds do not drop off at quite the rate that they had anticipated. Some days will be harder than others when sticking to a weight loss or maintenance program. A successful weight-loss program requires the individual to persevere and not give up when self-change seems too difficult. Some people might need to reset their goals, potentially by adjusting the total number of calories they are aiming to eat or changing their exercise patterns. The important thing is to keep a positive outlook and be persistent in working toward overcoming the barriers to successful weight loss. Losing weight Successful weight loss does not require people to follow a specific diet plan, such as Slimming World or Atkins. Instead, they should focus on eating fewer calories and moving more to achieve a negative energy balance. Weight loss is primarily dependent on reducing the total intake of calories, not adjusting the proportions of carbohydrate, fat, and protein in the diet. A reasonable weight loss goal to start seeing health benefits is a 5–10 percent reduction in body weight over a 6-month time frame. Most people can achieve this goal by reducing their total calorie intake to somewhere in the range of 1,000–1,600 calories per day. A diet of fewer than 1,000 calories per day will not provide sufficient daily nutrition. After 6 months of dieting, the rate of weight loss usually declines, and body weight tends to plateau because people use less energy at a lower body weight. Following a weight maintenance program of healthful eating habits and regular physical activity is the best way to avoid regaining lost weight. People who have a BMI equal to or higher than 30 with no obesity-related health problems may benefit from taking prescription weight-loss medications. These might also be suitable for people with a BMI equal to or higher than 27 with obesity-related diseases. However, a person should only use medications to support the above lifestyle modifications. If attempts to lose weight are unsuccessful and a person's BMI reaches 40 or over, surgical therapy is an option. Overview Maintaining weight loss involves a commitment to a healthful lifestyle, from which there is no "vacation." Although people should feel free to enjoy a special meal out, a birthday celebration, or a joyful holiday feast without feeling guilty, they should try not to stray too far from the path of healthful eating and frequent physical activity. Those who do may find that they lose focus. Gaining back lost weight is easier than losing it. Achieving and maintaining weight loss is possible when people adopt lifestyle changes in the long term. Regardless of any specific methods that help a person lose weight, individuals who are conscious of how and what they eat and engage in daily physical activity or regular exercise will be successful both in losing and keeping off excess weight.

Weight Loss On Keto Diet

Weight Loss On Keto Diet


Is a Weight Loss On Keto Diet effective for weight loss? The answer depends on whether it achieves a reduction in total kilojoule intake or not.

Weight Loss On Keto Diet?

A classical ketogenic diet follows a strict ratio for total grams of fat to combined grams of carbohydrate and protein and typically has 80-90% of total kilojoules coming from fat, which is very high fat. Carbohydrate intake varies from 20 to 50 grams a day, or 5-10% of total energy, while protein intakes are moderate.
The difference between weight loss on keto diet and diets that are described as low-carb is that ketogenic diets specifically aim to achieve elevated blood levels of ketone bodies which are chemicals produced as a consequence of your body burning fat. Hence general low-carb diets are not as high in fat as classical ketogenic diets.
Research on the use of classical ketogenic diets for weight loss is limited. But there are many studies that compare lower-carb diets to other approaches.
These show that aiming for a carbohydrate restriction of 20-30 grams a day, without setting a daily kilojoule target, leads to 2-4 kilograms greater weight loss compared to a low kilojoule diet, in studies up to six months.
In longer studies with follow-up between one to five years there is no difference in weight loss. A review of weight loss diets with a moderate carbohydrate restriction (45% or less of total energy intake) compared to low fat diets (under 30% fat) found they were equally effective in reducing body weight in studies from six months to two years.

How much carbohydrate do we eat?

In Australia, current carbohydrate intakes range from approximately 210 to 260 grams a day, or about 45% of total energy intake. More than a third of what Australians currently eat comes from discretionary, or “junk” foods. It is definitely a good idea to cut down on discretionary foods. These are commonly ultra-processed and contain refined carbohydrates and include burgers, chips, pizza, crumbed foods, biscuits, cake, pastry, lollies, cordial, sugar sweetened juices and soft drink.
The problem is most people do not eat enough minimally processed, nutrient rich foods that contain carbohydrate, like legumes, wholegrain breads, cereals and other grains, vegetables, fruit, nuts, milk and yoghurt. These foods contain important nutrients, from dietary fibre, to B vitamins, and minerals and trace elements like iron, zinc, magnesium, calcium, selenium and iodine.
Your body needs these nutrients for digestion, metabolism, growth and repair of cells and to help protect the brain, heart, muscles and nerves.

What happens when you go on weight loss on keto diet to lose weight?

If you severely limit all foods that contain carbohydrate, such as during a ketogenic diet, you end up cutting out many foods. This means you eat less total kilojoules and therefore lose weight.
Whether you follow a classical ketogenic diet or a very low energy diet you may end up producing “ketone bodies”, which may help with weight loss, particularly fat mass.
Carbohydrate is used in the body as the major source of fuel, like petrol is used to fuel a car. Your body has a store of carbohydrate in the liver and muscles called glycogen. When glycogen stores are low your body switches to burning fat, which leads to production of ketone bodies.

Glycogen becomes limited when your total energy intake is very low, such as during a strict Weight Loss On Keto Diet, a fast, or when you do not eat foods containing carbohydrate. This means your body burns the fat you eat, as well as body fat, leading to a loss of stored body fat. You still produce small amounts of glucose through a process called gluconeogenesis by breaking down protein and some fat.

weight loss on keto diet and appetite

A systematic review evaluated how people perceived their appetite before and during a very low energy diet that contained less than 3,300 kilojoules a day or a ketogenic low carbohydrate diet containing less than 10% energy from carbohydrate (50 grams or less per day). Those following the very low energy diet reported less hunger and greater fullness and satiety during weight loss, while those following the ketogenic diet reported feeling less hunger and having less desire to eat. The authors concluded that although the absolute change in subjective appetite ratings were small, they were important in terms of helping people stick to a weight loss diet.
One research study followed 18 obese men during eight weeks of a ketogenic very low energy diet of 2300-2700 kilojoules per day, followed by four weeks of weight maintenance. They measured changes in appetite and blood concentrations of appetite hormones and ketones.
While hunger increased significantly by day three and up until the men lost 5% of their starting body weight, it did not get worse after that while they were dieting. Once they increased their food intake during maintenance, they had an increase in hunger. The good news was that while they were producing ketones, they appeared to be able to tolerate feeling hungry.

Weight Loss On Keto Diet

One randomised controlled trial randomly allocated 45 obese adults to either a ketogenic low energy diet of 2500-300 kilojoules per day for about two months or a low kilojoule diet where total daily energy intake was reduced by 10%.
As you would expect, those in the low energy group lost significantly more weight after one year. After two years, and accounting for those who dropped out, both groups lost weight (low energy 7kg versus 5.3kg low kilojoule). Of note was that a greater number in the low energy group lost 5% or more of their initial body weight at 12 months.
A systematic review  of nine studies in adults with type 2 diabetes following lower-carb diets (less than 130 grams a day or less than 25% energy from carbohydrate) compared to control weight loss diets found weight loss was greater up to one year in the lower-carb groups.
While there was no long-term difference in weight loss between dietary approaches, blood triglyceride concentrations were significantly lower and HDL (good) cholesterol concentrations were higher, but there was no reduction in total or LDL (bad) cholesterol.

Should you or Not you Weight Loss On Keto Diet?


If you have a family history of bowel cancer then don’t follow a ketogenic weight loss diet. The World Cancer Research Fund has shown convincing evidence for a higher risk of colorectal cancer in association with low fibre and higher red and processed meat intakes.
Prevention guidelines recommend having greater variety, and higher intakes, of legumes, wholegrains, non-starchy vegetables and fruit.
When it comes to weight management, reduce your carbohydrate intake by reducing energy-dense, nutrient-poor foods. Increase minimally processed foods high in fibre and phytonutrients, including vegetables, legumes/pulses and wholegrains and only use classical ketogenic diets under supervision of your health care team.
