Trying to lose weight does not mean that a person has to give up all the snacks. Certain snacks, such as almonds and hummus, can help a person achieve their weight loss goals. Contrary to popular belief, when a person tries to lose weight, they don’t have to avoid eating or just eat at mealtime.
According to the American Heart Association (AHA), skipping foods to lose weight generally works against you because it causes a person to overeat.
However, when a person satisfies their hunger with healthy snacks, they are much less likely to want to eat unhealthy foods or exceed their calorie limit.
What makes food good for weight loss?
Eating healthy snacks can help a person lose weight.
Some foods are better for weight loss than others.
In general, foods rich in fiber or protein tend to fill more. This means that the person will feel satiated more quickly and will be able to eat less at each snack or meal.
Other considerations are finding foods that are low in calories but high in volume or density. The more space a food occupies in the stomach, the fuller the person can feel. Again, this helps a person eat less with each snack.
People may also want to consider foods that help with metabolism and energy. Greater energy can help a person burn more calories, and better metabolism can help a person process the food they eat more efficiently.
People looking to lose weight should avoid foods that contain large amounts of:
- saturated fat
- simple carbohydrates
Unprocessed foods are good options because many processed snacks contain high levels of sugar, salt, or both. Eating snacks between meals can help you lose weight. Eating snacks with healthy options can help prevent someone from overeating, as well as provide vitamins, fiber, and protein.
The following are some of the best weight loss snacks.
1. Hummus and vegetables
Hummus is a traditional Mediterranean dish prepared with chickpea puree. Due to its increasing popularity, there are often several flavor options for premade hummus sauces available in stores. People can also make hummus at home.
According to a 2016 study, hummus offers many potential benefits. Hummus provides a good source of protein and fiber, which can help a person feel fuller faster.
When people eat hummus with vegetables, they are getting the benefits of hummus, as well as any other additional nutrients from vegetables.
2. Celery sticks and nut butter
Celery is a low calorie vegetable. According to the United States Department of Agriculture (USDA), two large stalks of celery count as 1 cup of vegetables out of the 2.5 cups needed per day for a 2,000-calorie diet.
Celery is primarily water, which can help a person feel full. Dipping celery in nut butter, such as peanut or almond butter, can also provide the benefits of healthy fats and protein.
3. Fruit and nut butter
Apples and peanut butter are a good diet snack.
People can be creative with their fruit and nut butter combinations if they want. According to the USDA, a medium apple provides 20 percent of a person’s dietary fiber, and 1 of the 2 recommended cups of fruit each day.
Dipping a slice of apple in peanut or other nut butter also adds protein and good fat to a person’s snack.
4. Low fat cheese
Low-fat cheese is a source of protein and calcium.
Low-fat cheese products offer many nutrients and less fat than regular cheese.
Some of the benefits include:
- protein source
- calcium source
- source of other vitamins and minerals
Low-fat cheese also contains fewer calories than whole cheese.
What can be eaten with a low carb diet? Here are some tips for a low carb diet.
Walnuts can be a very healthy and filling snack.
Walnuts provide good protein and fat. However, those looking to limit their salt intake should check the label to make sure there is no added salt. Also, a person should avoid flavored cooked nuts, as flavors often contain sugar or salt.
People should look for raw or dry roasted nuts. Walnuts are relatively high in calories, so a person should only eat a small amount per snack.
6. Hard boiled eggs
Eggs are an excellent source of protein. However, in previous years, many people thought that eggs were unhealthy due to concerns about cholesterol.
However, more recent research suggests that eggs do not raise cholesterol levels and contain many essential nutrients.
7. Greek yogurt with berries
Greek yogurt is high in protein and calcium and low in fat and calories. A person can safely add fresh fruit or nuts to Greek yogurt to improve its flavor and add nutritional value.
The best Greek yogurt for weight loss is the simple variety. Greek flavored yogurts often contain extra sugar, which is not good for weight loss.
Edamame is a legume that a person can eat as a snack. Like other legumes, edamame is a source of fiber and protein.
It is also high in potassium, iron, and magnesium. When people eat it between meals, edamame can help a person feel more satisfied while providing some essential nutrients.
9. Popcorn with air
Popcorn is a popular snack in the U.S. Often you get a bad reputation because of the extra amount of sugar, fat, or salt that people put on you.
Air-popped popcorn does not contain these additional ingredients. Simple popcorn is a low-calorie whole grain that offers plenty of filling fiber.
How to add them to your diet
A person may find it helpful to prepare healthy snacks beforehand.
The most effective way to add healthy snacks to your diet is to keep a stock of them in an easily accessible location.
For example, a person could prepare a week of snacks at the beginning of the week. Once prepared, the person can divide the sandwich into individual portions.
For example, a person can prepare hummus in a large batch at the beginning of the week by mashing chickpeas with olive oil, tahini, and seasonings in a food processor.
After preparation, they can put the hummus in small containers and accompany each container with a bag of carrot sticks.
Those who don’t have time to make their own sandwiches can search for sandwich-sized portions sold at grocery stores. Many products come prepackaged in snack sizes.
People looking for pre-made and proportioned snacks should know that they are often more expensive. They will also have to be on the lookout for added sugars, salt, and fat.
Eating healthy snacks can play an important role in helping a person lose and control their weight.
People should look for snacks that are low in sugar, fat, and salt. They should also look for snacks rich in nutrients like fiber and protein.
Beans, nuts, and raw vegetables and fruits are often good choices that will help a person feel fuller and provide the necessary nutrients.

Membrane filters you need to know and their properties
Membrane filters or commonly known as “membranes” are microporous membranes with specific pore size ratings. It is also called a sieve, microporous filter, or screen. Cellulose acetate membrane filter preserves or filter particles bigger than the pore size. If there are particles slighter than the pore size, other mechanisms will be used. There are different types of membrane filters, such as nylon, cellulose acetate, mixed cellulose ester, or MCE membrane filters. Here are more membrane filter types and their attributes.
The mixed cellulose ester
MCE is composed of cellulose acetate and nitrocellulose. It has a high porosity and can provide a higher flow rate. It also has a high level of protein binding, which can be prohibited by pretreatment or application. MCE is a standard membrane that can be used in many laboratory applications, such as filtration and sterilization of biological fluids, pollution analysis, microbiology, and air monitoring. The membrane is able to be converted into transparent to view the particles collected during the filtration process.
coated cellulose acetate consists of cellulose acetate cast on a non-woven polyester carrier. It has a non-fiber releasing ability, and the protein binding level associated with nitrocellulose is low. It also has a low level of static charge and chemically enhances compatibility with low molecular weight alcohols. The coated cellulose acetate is used as a pre-filter or clarification filter.
Hydrophilic PTFE has characteristics described as having the greatest resistance to chemicals and pH. The membrane has a high level of flow rate and almost no water-extractable. When the membrane is wetted with water, it is transparent to the naked eye, so it is very suitable for use in HPLC, organic solvents, and other aqueous mixtures.
PTFE The characteristic of hydrophobic PTFE is that it has a high porosity is very thin and behaves like a monolithic retention membrane. It also has a passive effect on most corrosive chemical solvents, alkalis, and strong acids. The membrane traps water-containing aerosols by sterilizing the gas. It is also used for gas and air discharge so that gas can freely pass through the membrane, and at the same time prohibit liquid from entering. This protects the best samples and vacuum pumps. In addition, hydrophobic PTFE clarifies and sterilizes strong acids and other solvents that are incompatible with other membrane filters.
nylon membrane filters are made by impregnating polyester fiber webs with polymers made of nylon. This makes the membrane durable, heat-resistant, and essentially hydrophilic. Because it is hydrophilic, it is suitable for alcohol and aqueous samples. The membrane filter can be used to sterilize, filter, and clarify organic aqueous solutions.
The membrane filter is composed of diacetate and cellulose triacetate. It is characterized by high strength and low electrostatic charge. The advantage of using it is that it can be repeatedly disinfected without losing its integrity or changing its bubble point. Associated with MCE membrane filters in stipulations of their solvent confrontation to alcohol molecular weight increase at low levels. Cellulose acetate is used to enhance the recovery of positive organisms and filter enzyme solutions. It is also used for cytological diagnosis and receptor binding research.

Rapid production of porous cellulose acetate membrane for water filtration using readily available chemicals
We describe a chemistry lab experiment using everyday elements and readily available chemicals to introduce porous polymer membranes to high school and college students. The principle of membrane filtration is illustrated by filtering solutions containing watercolor pigments or food coloring, while the food coloring is completely soluble in water and easily passes through the membrane. . The laboratory experiment can be performed in a 2 hour activity and is intended to (1) expose students to an exciting new field of materials science. He familiarizes them with porous membranes for the production of drinking water and presents them with a model elimination technique that uses the acid / base theory. In Switzerland, 52 high school students and 55 high school teachers have already successfully completed the laboratory experience and found the activity interesting and motivating.
Importance of safe drinking water
Access to clean and safe drinking water remains a global problem. In developing countries, around 80% of diseases are linked to poor water and sanitation conditions. Among the most common health risks of unclean drinking water are water-borne illnesses caused by pathogenic bacteria, viruses, and protozoan parasites. In a comprehensive study, Bain and colleagues examined the microbial quality of drinking water and estimated that approximately 1.8 billion people worldwide use a source of drinking water contaminated with E. coli or other bacteria. thermotolerant coliforms (TTC).
Various approaches, with their inherent advantages and disadvantages, have been studied for eliminating microorganisms linked to waterborne diseases. The portable water purification devices currently in use include systems based on ultra and microfiltration membranes, ceramic filters, activated carbon filters or chemical halogen disinfection. The disadvantages of the most efficient systems are, in general, their complex installation and their periodic maintenance, which leads to high operating costs and, consequently, makes these systems unsuitable for developing countries. In addition, many point-of-use treatment devices are not effective against all possible contaminants. Therefore, new water treatment technologies are being explored.
Water quality issues are an integral part of many high school chemistry courses, and various experiments have been developed as educational laboratory procedures. Water filtration experiments for the removal of nanomaterials have already been described and a laboratory experiment comparing various biochemical separation technologies (including filtration) has been presented. The experience presented here differs from previous approaches in that the filtering device itself (a porous membrane) is made by students from standard materials, then its separation performance is tested.
Cellulose Acetate Membrane for Water Filtration
In this article, we describe a laboratory experiment to produce a cellulose acetate membrane filter for drinking water which, in its production stages, resembles the commercially available water filter, but which is accomplished using everyday items such as a kitchen blender, glass dishes, rulers and chemicals readily available. The entire experiment can be performed in a 2 hour laboratory exercise. Supporting information for this article includes a student brochure and instructor notes for conducting the classroom experience (approximately 20 to 40 students). The production of membranes is based on the addition of calcium carbonate to a solution of cellulose acetate dissolved in acetone. Glycerol is also added to the reaction mixture and acts as a pore spacer. The polymer solution is then mixed using a kitchen mixer, and the resulting dispersion is spread on a glass plate using a stainless steel ruler. After evaporation of the solvent in ambient air, the calcium carbonate and glycerol particles are washed from the polymer matrix in an acid bath and then rinsed in a water bath.
Functional test of the membrane using watercolor and food coloring
Students test the performance of the membrane obtained with a solution of watercolor and food coloring. Although, when mixed with water, both give colored water, the color of the food used is a water-soluble dye, and watercolor is a dispersion of pigments, with particles between 40 and 80 µm in size. The watercolor solution based on pigments is first passed through the membrane. Then the filtration is repeated with the food coloring solution. In both cases, students are invited to record their observations. The experiments with the two solutions are then repeated with a standard filter for a Buchner funnel.
Equipment and chemicals
The experiment uses the infrastructure and materials available in a university-level chemistry laboratory (see Information on teaching support and notes to students), as well as certain additions, which can be easily obtained:
• Kitchen mixer with at least 800 W of power (eg Philips HR 2195/04)
• Mirror or glass plate (148 × 210 mm2 or larger area)
• Ruler with stainless steel edge or aluminum profile.
• Two plastic tanks for dilute hydrochloric acid and a double boiler.
• Cellulose acetate (Sigma-Aldrich n ° 180955)
• Calcium carbonate (Sigma-Aldrich No. 21069)
• Watercolor (for example, Artists Loft Fundamentals watercolor pans set on amazon.com)
• Food coloring (for example bright blue FCF E133)
Preparation of a solution of cellulose acetate polymer
Preparation of the cellulose acetate dispersion
All of the cellulose acetate membrane filter was transferred to a kitchen mixer. Then, 41 g of calcium carbonate and 17.6 g of glycerol were added, and the suspension was stirred for 3 minutes in the highest setting of the kitchen mixer. The dispersion was placed in a new 250 ml Schott bottle and closed to limit evaporation of the solvent. The kitchen mixer was immediately filled with water to precipitate the remaining dispersion and the polymer waste was deposited in household waste.
Removal of calcium carbonate particles
To remove the calcium carbonate particles, a plastic container was filled with 5 L of water and another container with 5 L of hydrochloric acid (0.24 M). The mirror plate containing the membrane sheet was then immersed in the hydrochloric acid bath. The membrane sheet was released from the mirror plate, and gas bubbles indicated the removal of the calcium carbonate particles. After 10 minutes, the membrane sheet was transferred to the container containing only water and washed for an additional 5 minutes. Finally, the membrane sheet was removed from the water bath and placed on a cloth. Another kitchen towel was used to dry the membrane.
Orlando Dermatologist Reports Coronavirus Rash- Sunlight Needed for Vitamin D
Getting to deal with a whole new disease is very unsettling. No one has answers to anything, and that is enough to cause panic across any nation.
Well, that is precisely what is happening now with the Coronavirus. All the symptoms cropping up from different areas is bringing in more worry and doubt. The Coronavirus is an upper respiratory disease that gets in the way of your breathing, and it makes it harder for air passage in and out of the lungs. And now, there is something else worrisome — the Coronavirus rash.
So what is this rash, and where has it come from?
Is there any relation between skin rashes and Coronavirus
Doctor around the world including any Orlando dermatologist attest that it is not unusual to see skin rashes on someone infected with a viral infection. Just like herpes that appears around the lips and chickenpox that present all over the body.
The reasons this can happen is one, the rashes are a by-product of a robust immune system fighting against the virus. And two, it could be that the virus is directly affecting the skin cells as in the case of the chickenpox. Studies on the sources and targets of the coronavirus rash are still unknown.
The rashes have manifested in several ways so far. These are:
- Head to toe rashes
- Hive-like eruptions
- Purple rashes across the body
- Bumps and lesions on the heels and toes
Now, what is perplexing is that these rashes are presenting on younger coronavirus patients. But any Orlando dermatologist should not make any conclusions yet as it is known that sometimes viral infections can impact almost every organ in the body, including the skin. The astonishing part is that the rashes are presenting differently from one patient to the other.
Types of rashes reported
The first kind of rash is the Livedo reticularis which is a vascular condition. It is characterized by mottled, purplish discolourations that mostly appear in the legs and appear to form a net-like pattern.
This rash appears like a bright red, pinpoint rash that is commonly seen in other ailments. It is caused by bleeding under the skin.
A vesicular rash is diagnosed when a rash appears in the same spot as multiple vesicles with fluid trapped under the top layer of skin. The blisters are painful to touch, which make it hard to resist touching because they are itchy.
This is a chicken-pox-like rash that appears specifically on the toes. It seems to be raised, looks like frostbite because of the purple lesions. These rashes are what has been named the COVID toes.
These rashes look like measles rashes. They consist of maculopapular skin eruptions and are mostly because of hypersensitivity in patients taking antiretroviral and antiepileptic drugs. It is also a common outcome in viral infections like Coronavirus.
These are commonly known as hives or nettle rash. They are an outbreak of red bumps that are mostly triggered by several things, include medication reactions, allergies and infections.
Is there a cure for these rashes?
Any Orlando dermatologist would love to say that there is, but there is no known cure for the rashes. What doctors are doing is keeping the lesions in control using anti-inflammatory medications. And the fact that they are presenting in different forms makes it more challenging to come up with one specific cure.
With that said, it is still advisable for anyone showing any of the above symptoms to seek medical assistance immediately. Not all rashes are a result of Coronavirus, so it is safe to see a doctor first. So eat right and know that sunlight needed for vitamin D, especially in people of colour is essential too.
