the fundamental cause of obesity is the energy intake exceeds energy expenditure , Calorie intake from energy materials of food, protein (4kcal / g), fat (9kcal / g), carbohydrates (4kcal / g), calories consumed mainly by three aspects: basal metabolism, physical activity and thermic effect of food. the aim of Weight loss is that the heat reaches a negative balance (calorie intake is less than calorie consumption)
How to test ??
testing of index
BMI index is the abbreviation of Bo dy Mass Index, BMI Chinese is "Body Mass Index" means, based on your height and weight calculated. BMI is recognized worldwide as a hierarchical method of assessing the degree of obesity, the World Health Organization (WHO) also BMI to define overweight or obesity. Specific BMI is calculated as body weight in kilograms divided by height squared (in meters).
The formula is: body mass index (BMI) = weight (kg, kg) / height squared (m, m)
Ideal body weight (Kg) = (18.5 ~ 23.9) × the square of height (in m)
For example: a person's height is 1.75 meters, weight 68 kg, his BMI = 68 / (1.75 ^ 2) = 22.2 (kg / m ^ 2) When the BMI index of 18.5 to 23.9 is normal
But note that not everyone is suitable for BMI Index. Such as:
⒈ under 18 years of age;
⒊ doing weight training;
⒋ pregnant or lactating;
⒌ virtual body is weak or sedentary elderly.
How To Lose Weight Fast and Safely
1. Eat plenty of proteinGhrelin is made in the digestive system, and it is called the hunger hormone because it increases your appetite when your body needs energy to use. Being able to suppress the effects of ghrelin would help us to turn off this weight gain hormone. Research published in the American Diabetes Association found that ‘Ghrelin administration stimulates GH secretion but also causes weight gain by increasing food intake and reducing fat utilization in rodents.’ The researchers looked at lean and obese people’s levels of this weight hormone. They found that ghrelin was found in lower concentrations in obese people compared to lean people. To turn off your ghrelin hormone so you won’t gain weight, eat a diet high in protein and avoid high fat foods. Protein helps suppress ghrelin production in the digestive system to keep you from eating more and gaining weight.
2. Remove sugar from your dietSugar is sneaky because it shows up in many forms in many foods. Getting rid of it entirely can be a challenge in label reading. However, it may be the best thing you can do to turn off your weight gain hormone insulin. Insulin is most closely associated with the disease diabetes, which affects millions of people worldwide. The pancreas produces insulin to help digest sugars that you eat. High levels of insulin in your blood can affect your likelihood of weight gain. Insulin helps glucose to be absorbed by the cells and stored as energy, which is why you can gain weight when you have more sugar in your diet. Storing energy in fat cells is not what you need when you want to turn off weight gain.
3. Eat less dairy
Hormone free dairy products aren’t necessarily a safe means of avoiding extra hormones that can cause weight gain. The dairy industry has been responding to public pressure to provide hormone-free dairy products to consumers, based on research that shows that eating animal hormones may trigger early development in teenage girls and boys.Nutritional and medical experts have realized that the milk that cows and other animals provide is meant to grow and raise their own young, not humans. Avoid these non-human hormones that can mess with your own.
4. Avoid soy products
Women undergoing menopause experience a natural decrease in the estrogen that their body produces now that they are no longer able to bear children. As a result of the decreased estrogen, body fat increases. Soy products contain phytoestrogen, which can block the human normal estrogen in the body.Estrogen has a role in the production of leptin. Leptin is one of the most important hormones to turn off weight gain because it regulates satiety. Satiety is how satisfied we feel when we eat. If we don’t feel satisfied or sated, we will continue to eat, even if we don’t actually need to eat.Researchers studying the role that estrogen has on leptin levels found that ‘In humans, serum leptin concentration was higher in premenopausal women than in men, and in postmenopausal women it was lower than in premenopausal women, but still higher than in men.’The same researchers found that in premenopausal women, serum leptin levels were significantly higher in the luteal phase or the later part of their menstrual cycles. This research suggests that increasing estrogen levels through dietary changes could help increase the production of leptin, which can help turn off weight gain.
5. Reduce stress and caffeine intake
The stress hormone cortisol is released when we are frustrated, overwhelmed or feeling stuck. Stress eating is real and people who binge, especially on so called ‘comfort foods’ are likely to be engaging in a destructive pattern of behavior that will lead to weight gain.Rather than allowing your stress to dictate when you eat, seek to reduce sources of stress in your life to reduce cortisol levels in your body. If work is overwhelming, delegate parts that someone else can handle. If your home life is stressful, sit outside in nature for 5 minutes while breathing deeply to relax and recharge.Caffeine levels can also increase the level of cortisol that is being released in your body.Turn off the weight gain by reducing your caffeine intake and the hormone cortisol will be reduced as well.
6. Eliminate grains
Grain consumption has been linked to thyroid hormone production being slowed down. Reducing your intake of grains in your diet can help regulate your thyroid hormone levels and turn off weight gain.The thyroid is one of the most important factors to consider when examining weight gain. Check with your medical professional to have your thyroid levels checked if you suspect that your weight gain is caused by a low-functioning thyroid gland.
7, Weight Loss Pills and Supplements intake
Weight loss raw material
Weight loss injection & Peptides Melanotan (MT II )
Additionally, there are many prescription weight loss pills that have been shown to be effective.
The most common ones are Contrave, Belviq, Phentermine and Qsymia.
According to a recent 2016 review study, even prescription weight loss pills don’t work as well as you would hope.
On average, they may help you lose up to 3-9% of body weight compared to a dummy pill (47).
Keep in mind that this is only when combined with a healthy weight loss diet. They are ineffective on their own, and hardly a solution to obesity.
Not to mention their many side effects.
Take Home Message
Out of the all these are the clear winners, with the strongest evidence to back them up:
Weight loss: Glucomannan, CLA and Orlistat (Alli).
Increased fat burning: Caffeine and green tea extract.
However, I have to advise against Orlistat due to the unpleasant side effects, and against CLA due to the harmful effects on metabolic health.
That leaves us with glucomannan, green tea extract and caffeine.
These supplements can be useful, but the effects are modest at best.
Unfortunately, NO supplement or pill really works that well for weight loss.
They may give your metabolism a bit of a nudge and help you lose a few pounds, but that’s where it ends, unfortunately.
Cutting carbs and eating more protein are still the best ways to lose weight, and work better than all the diet pills combined.
