Is Starch Really the Enemy? Debunking Nutrition Myths for Weight Loss

Is starch toxic powder??

Hello, I recently visited a weight loss doctor who advised me to avoid all carbohydrates, suggesting that I shouldn't eat any at all during my meals, claiming that carbohydrates are "toxic." However, I can eat other foods, like those found in a buffet, and it's okay if they are oily as long as they are not deep-fried.
The doctor also mentioned that eating full-fat cheese before bed is acceptable.
Of course, I should avoid fried, sweet, and thickened foods, and I shouldn't eat too much.
I would like to ask you, from a nutritional perspective, whether this kind of diet is good or bad for the body, and if it is truly effective for weight loss.
Additionally, I would like to know what dietary considerations should be taken if blood lipids are too high.
What are the consequences of having high blood lipids? Lastly, what are the benefits of taking cod liver oil before bed? Thank you.

1.
Each gram of starch provides 4 calories, while each gram of fat provides 9 calories.
For those who need to lose weight, which source of calories would you choose wisely?
2.
High blood lipids are a significant risk factor for atherosclerosis and are closely related to cardiovascular diseases.
To prevent elevated blood lipids, it is essential to maintain an ideal body weight and reduce fat intake.
Limit the consumption of animal fats such as lard and butter, and use cooking oils that are higher in monounsaturated fatty acids, such as olive oil, canola oil, and peanut oil.
Additionally, reduce the intake of high-cholesterol foods like organ meats and egg yolks, and increase the consumption of foods rich in omega-3 fatty acids, such as mackerel and salmon.
Also, remember to avoid alcohol.

3.
The primary purpose of taking cod liver oil is to supplement vitamin A; however, modern individuals rarely experience vitamin A deficiency, so additional supplementation is generally unnecessary.
Dark-colored vegetables, such as carrots, contain carotenoids that can be converted into vitamin A within the body.

The notion that starch is the enemy in weight loss is a common misconception that needs to be addressed with a balanced perspective on nutrition. Starch, which is a type of carbohydrate, is an essential macronutrient that provides energy for our bodies. It is found in foods such as grains, legumes, and vegetables. While it is true that excessive consumption of refined carbohydrates and sugars can lead to weight gain and health issues, completely eliminating starch from your diet is not a sustainable or healthy approach.

From a nutritional standpoint, carbohydrates, including starches, are crucial for maintaining energy levels, especially for those who are active or have demanding lifestyles. When you consume carbohydrates, your body breaks them down into glucose, which is used as a primary energy source for your cells. This is particularly important for brain function, as the brain relies heavily on glucose for energy.

The advice to avoid all starches and focus solely on non-starchy vegetables and fats can lead to a lack of essential nutrients. Whole grains, for example, are rich in fiber, vitamins, and minerals, which are vital for overall health. Fiber aids in digestion, helps regulate blood sugar levels, and can contribute to feelings of fullness, which can be beneficial for weight management.

Regarding the consumption of fats, it is essential to differentiate between healthy and unhealthy fats. While healthy fats (such as those found in avocados, nuts, seeds, and olive oil) can be beneficial for heart health and satiety, consuming excessive amounts of unhealthy fats (such as trans fats and saturated fats found in fried foods and processed snacks) can lead to weight gain and increased cholesterol levels.

As for the concern about high blood lipids, it is crucial to adopt a balanced diet that includes a variety of food groups. Reducing saturated fats and trans fats while increasing the intake of healthy fats, fiber, and lean proteins can help manage blood lipid levels. Foods rich in omega-3 fatty acids, such as fatty fish, flaxseeds, and walnuts, are particularly beneficial for heart health.

If you have high blood lipids, you should also consider the following dietary tips:
1. Increase Fiber Intake: Incorporate more fruits, vegetables, whole grains, and legumes into your diet. Soluble fiber, in particular, can help lower cholesterol levels.

2. Choose Healthy Fats: Opt for unsaturated fats found in olive oil, avocados, and nuts while limiting saturated fats from red meat and full-fat dairy products.

3. Limit Sugar and Refined Carbohydrates: Reduce your intake of sugary foods and beverages, as well as refined grains, which can contribute to weight gain and poor lipid profiles.

4. Stay Hydrated: Drink plenty of water and limit sugary drinks and alcohol.

Regarding the consumption of cod liver oil before bed, it is rich in omega-3 fatty acids and vitamins A and D, which can support overall health. Omega-3s are known for their anti-inflammatory properties and can help improve heart health. However, it's essential to consume it in moderation and consult with a healthcare provider, especially if you have specific health concerns or are taking medications.

In conclusion, while managing your carbohydrate intake is important, completely eliminating starches is not the answer. A balanced diet that includes a variety of nutrients, along with regular physical activity, is the most effective and sustainable way to achieve and maintain a healthy weight. If you have specific dietary concerns or health conditions, it is advisable to consult with a registered dietitian or healthcare professional for personalized guidance.
