Intermittent Fasting – Time-Restricted Feeding for Muscle Gains & Fat Loss

If the time-restricted feeding group had increased protein in their diet, they may have been able to maintain lean muscle mass. More research needs to be conducted, but the current study found that time restricted feeding with protein at 1.0 kg/bw was not enough to maintain lean muscle mass, however strength levels were maintained.

[sociallocker id=”3449″][/sociallocker]Let’s face it; dieting sucks and everyone is looking for a solution to make life easier when it comes to cutting calories. The newest trend is intermittent fasting diet, in which periods of fasting are combined with periods of re-feeding. Although there are different forms of intermittent fasting, a common theme is that each form of intermittent fasting utilizes repeated periods of fasting that extend beyond the duration of a typical overnight fast and typically lead to reductions in energy intake.

[sociallocker id=”3449″]

Intermittent fasting diet has been suggested to be ideal for losing body fat, but there is little research about gains in muscle mass. One form of intermittent fasting is time-restricted feeding which utilizes a daily schedule allowing a limited number of hours as a feeding window, and the remaining hours as a fasting window. A previous study investigating a time-restricted feeding for eight weeks (20 hours of fasting and 4 hours of feeding per day) consuming three meals per day. At the end of eight weeks, fat mass was significantly lower after eight weeks of time-restricted feeding. Interestingly, lean mass was greater by an average 1.5 kg after time-restricted feeding as well. Little is known what happens when you combine resistance exercise and if it’s possible to gain lean muscle mass while on a time-restricted feeding diet.

Researchers had subjects placed on a time restricted feeding consisting of a regular diet. The time restricted feeding group consumed all calories within a four-hour period for four days per week, but included no limitations on quantities or types of foods consumed during this four-hour period. So eat anything you want when you are re-feeding during this 4 hour period. Additionally, the subject’s consumed a resistance training program performed three days per week and consisted of alternating upper and lower body workouts. For each exercise, four sets leading to muscular failure between 8 and 12 repetitions. On the three days per week that participants performed resistance training, they were allowed unrestricted food intake. On non-workout days (four days per week), participants were required to consume all calories in any four-hour window between 4 p.m. and midnight.

At the end of the study, the time-restricted feeding group with no limitations on food consumed on exercise days while restricted feeding on non-training days was able to reduce energy intake in young exercising males by approximately 650 kcal per day of modified fasting. Despite the reduction in calories of 650 kcal, this did not translate into group body composition changes over the course of 8 weeks. One concerning result of the time-restricted feeding group was the loss of lean muscle. Subject’s performing resistance training and a normal diet gained 2.3 kg of lean muscle mass on average, as opposed to −0.2 kg in strength training -time-restricted feeding group, indicating that time-restricted feeding group may have hindered hypertrophic adaptations to resistance training. So why did the time-restricted feeding group lose muscle? The time-restricted feeding group resistance training consumed less protein. When calculated relative to body weight, the average daily protein intake in the resistance training-normal diet group was 1.4 g/kg body weight/day, whereas the intake in the resistance, training-time-restricted feeding group was on average 1.0 g/kg. This is well below the threshold recommendation of recently stated protein intake of 1.3–1.8g/kg, or perhaps higher, can promote lean mass retention during low-calorie diets.

Key Points:
If the time-restricted feeding group had increased protein in their diet, they may have been able to maintain lean muscle mass. More research needs to be conducted, but the current study found that time restricted feeding with protein at 1.0 kg/bw was not enough to maintain lean muscle mass, however strength levels were maintained.

Best skincare combinations that will work for your skin

The important thing to remember is to pair your skincare ingredients correctly together. Very few are power couples for the skin that might work and benefits your skin. The first trick, of course, is to not use all the products together. To maximise the benefits of the skincare ingredients, here are some important parings you should not miss:

1. Vitamin C with SPF

Vitamin C is an essential ingredient for skin care. It helps protect the skin from sun damage, fights the antioxidants, repairs the skin barrier, promotes collagen production, and acts as an anti-ageing ingredient. When combined with sunscreen, the two work to protect your skin from environmental damage and block the UV rays that filter through the sunscreen.

2. Niacinamide with salicylic acid

Niacinamide is an important ingredient for fortifying the skin barrier and treating hyperpigmentation. Salicylic acid is what your skin needs to keep the breakouts away. When they are used together, your skin will benefit from reduced pore size, prevent acne breakouts, improve skin strength and work against the signs of ageing. Together they also improve collagen and elastin fibres giving the skin a youthful glow from the inside.

3. Retinols with peptides

Move the retinol to your nighttime routine during this time of the year. Vitamin A derivatives are the gold standard for home skin care because they treat everything from acne to ageing to fine lines. Peptides help skin cells rejuvenate and repair. Together they correct your complexion, make the skin tighter and give a smoother and plumper look to the skin.

4. Vitamin C and vitamin E

Vitamin C is essential for skin rejuvenation and protection, and vitamin E helps keep the skin supple. You can use them together to protect the skin from oxidative stress and maintain the suppleness of the skin, leaving you to enjoy the weather in its full glory.

5. Hyaluronic acid with exfoliating acids

Spring is a good time for skin repair, and the AHAs and BHAs do a great job of removing the top layer of the skin, making the new skin sensitive to dryness, and hyaluronic acid is a humectant that restores dryness. Hyaluronic acid recharges skin hydration and has long-lasting benefits for the skin.

Things to remember

When using new skin combinations, make sure you take your skin type into account. Always do a patch test first and start when using these combinations 1-2 times a week along with your regular skincare routine and slowly increase the frequency as needed by the skin. Do not over-exfoliate or scrub the skin, focus on good skin care every day for great results instead.

Performance Supplementation

The sports supplements industry is one of the largest industries in the world of sports, especially with respect to revenue. Athletes are often attracted to these supplements by the effective marketing approaches used by marketers to sell these products. In sports, every athlete seeks to stage the best performances to achieve different milestones through their sporting life. The availability of supplements that can enhance the performance of these athletes makes them seductively attractive for these individuals.  No one would miss an opportunity to improve their performance, irrespective of the risks that exist. However, there is a need to ensure that these supplements are regulated. The lack of regulations in the sports supplement industry could lead to increased risks for the athletes. Perhaps we need to have a more standard approach to the management of sports supplements.

By Gabriel I. Escalera

     First, it’s essential to first have a better understanding of what sports supplements are in the sporting industry.  Sports supplements are additional nutrients that individuals can add to their normal diets to improve their physical abilities to perform in physical activities. Active athletes often include supplements in their diets to achieve sufficient nutrition for optimal performance in sports. In addition, athletes also use supplements to compensate for nutritional deficiencies. Most importantly, there is a belief among athletes that supplements significantly improve their abilities, helping them achieve higher performance.

        Supplements play an important role in the diets of athletes. As the name suggests, these substances should be used in addition to the normal diet, as opposed to being replacements. There are supplements that have been developed based on scientific evidence. This means that there are supplements in the market that can be beneficial to the athletes who consume them. There are several benefits that athletes can draw from using these supplements. One of the most significant benefits is that they can legally improve the performance of athletes. Other than that, supplements can also be used to attain the required weight for a specific sport’s weight classes. Similarly, they can be effective in losing weight for a specific sport. Supplements can also be used by athletes to build muscles and improve the circulation of oxygen within the body. Moreover, supplements also provide athletes with an option that helps them avoid the temptations of using other performance-enhancing drugs that are banned in most competitive sporting activities. As such, supplements are critical for athletes, especially with respect to the possibility of enhancing performances.

     There is a significant difference between performance-enhancing drugs and dietary supplements. There is a complete ban on performance enhancing drugs in the sporting world. However, dietary supplements are allowed within the sporting world. In the United States, the Food and Drug Administration (FDA) does not place strict regulations on sports supplements. So, the manufacturers of these substances are not required to submit samples of their products to the FDA.  The only requirement for sport supplement manufacturers is to make a claim of the health benefits of the supplement, based on scientific evidence. However, the FDA does not go beyond that to scientifically verify these claims.  Because of this there may be inadequate regulation of sports supplements, and this places the athlete at the risk of consuming substances that may be harmful to them.

     The use of supplements has continued to be a controversial topic among the stakeholders in the supplement industry.  These controversies tend to keep the conversation going and ensure that we can develop policies and laws that regulate the production and use of sports supplements. There are concerns about the processes involved in the manufacture of some sports supplements. The manufacturing process plays a significant role in determining the final product. The manufacturing process involves the use of different ingredients and processes that are not entirely known or understood. 

     Another important area of concern over sports supplements is that of the quality of these supplements. The quality of the supplement is critical however, the FDA does not require any quality standards on supplements. The FDA only requires that the manufacturers make a claim about the health benefits of these supplements. The FDA does not require the manufacturer to provide clinical or scientific trial results that verify the claims. This means that the manufacturers have considerable leeway to provide inaccurate information about the supplements to get approval from the FDA.  It is also possible that the manufacturers could create the same substance, give it a different name, and different claims to ensure that they are seen as different supplements. 

     Based on these observations, there appears to be a need to develop programs, policies, and laws that effectively regulate the production and sale of sports supplements. There is a need for the stakeholders, especially the FDA, to change the approach to the management of the supplements in the market. Regulations should be developed to streamline the manufacturing process.  Just like in the manufacture of medicines, there seems to be a need to regulate the manufacture of sports supplements. These supplements, when ingested, have the capacity to alter the body’s function. Their effects are similar to medicines. The regulation of the manufacturing process would ensure that there is a standard quality for every type of supplement. It could ensure that the most appropriate ingredients and processes are used in their manufacture.

     Quality control measures should also be implemented to ensure that the supplements are not harmful.  The quality of the supplements is dependent on scientific validation of their effectiveness in achieving the objectives for which they are created. As such, the FDA should implement programs that would compel the manufacturers to provide scientific verification for the health claims made. This would mean that quality is central to the development and production of the sports supplements. As such, it could provide a regulatory framework established to eliminate the safety risks associated with sports supplements. This way, sports supplements will be able to achieve their fundamental objectives without creating any controversy.

Spot reduction doesn’t work

Published

on

When it comes to achieving a desirable body, it is common for people to have problem areas such as love handles, flabby arms, sagging skin, or hips. The market is flooded with products that claim to eliminate fat or tone specific body parts, from creams and applications to gadgets and machines. However, the reality is that you cannot spot reduce, and the attempt to do so is not only futile but also potentially harmful.

There are several reasons why spot reduction is a myth. Firstly, a healthy diet is crucial in eliminating body fat, and consuming high-calorie and high-cholesterol foods can cause the accumulation of fat in problem areas. No matter how many gadgets you use, if you continue to indulge in unhealthy foods, you will not see results.

Secondly, spot reduction is a simplistic approach that overlooks the complexity of the body. Many products claim to require nothing but attaching or applying them to problem areas, neglecting other body parts and requirements. To achieve a healthy body, you need to understand the physiology of your body and what it takes to achieve your goals. For example, if you want six-pack abs, you need to focus not only on abdominal exercises but also on reducing body fat and increasing body mass through a healthy diet and cardio exercises.

Thirdly, there are no shortcuts to achieving a healthy body. Miracle diets, pills, and potions may seem like a quick fix, but they will ultimately lead to a dead end. To achieve a healthy body, you need to put in the work and earn it.

Finally, committing to the health of your body is a lifelong dedication. Even if you achieve a desirable body now, it will not remain so forever if you abuse your diet and lifestyle. Therefore, it is essential to develop a holistic approach to your health and fitness, incorporating not only exercise and diet but also a positive outlook on life.

In conclusion, the key to achieving a desirable body is to do it the proper way. There are no shortcuts or quick fixes, and spot reduction is a myth. Instead, focus on developing a healthy diet and exercise program that addresses the whole body, and commit to a lifelong dedication to your health and well-being. By taking matters into your own hands, you can enjoy the benefits of a healthy body and a positive outlook on life.
