Chromium fat burner? Can it help to lose weight safely and effectively? Let’s figure out…
Chromium is one of the most used ingredients in weight loss products. It is probably an active ingredient in well over dietary supplements. But, as the research will show, there is little evidence to suggest chromium fat burner as an option to think about!
In the I970s, chromium drawback was recognized in humans on long-term total parenteral nutrition. It also characterized by insulin resistance and high cholesterol (hypercholesterolemia).
More studies report that chromium acts as part of the glucose tolerance factor (GTF). The way it works is by increasing the effectiveness of insulin.
In type II diabetics, chromium supplementation improved fasting blood glucose and insulin levels. This result was obtained after 2 and 4 months of treatment.
This is important because chromium may improve insulin sensitivity in this population.
Chromium appears to act by increasing the rate of insulin internalization. It could be due to an increase in membrane fluidity.
Human Studies on Chromium Fat Burner
Because chromium can increase the sensitivity of muscle cells to insulin! Thus it can improve amino acid transport into the muscle.
The researchers theorized during strength training programs, chromium supplementation can increase muscle mass. It also concurrent losses in fat weight than training alone.
In the beginning, it was not researched as a chromium fat burner supplement. It considered and researched as an aid to increase muscle mass during training.
The chromium fat burner, will occur after the gains in muscle mass and resting metabolic rate associated with the gain in muscle.
Thus, it would make sense, if chromium does work! It will only be under the exercise condition, and chromium fat burner will be a secondary benefit.
Furthermore, it would also suggest that chromium would be ineffective as a fat loss product without exercise.
This further supports the fact! The fat loss can be done only by reducing the caloric intake and increased caloric expenditure.
Lack of evidence in the Hasten study
Initial studies did report an increase in body weight during a 40-day and 12-week training program. But, in the Hasten study, it happened in females only! The results of this study are questionable.
Though the authors reported an increase in FFM. There was no increase in strength associated with the increase in FFM.
Also, body composition was determined by skinfold measurements. The body weight was tested with the subjects wearing shorts, T-shirt, and tennis shoes.
No mention was made as to whether the researchers required the subjects to wear the same clothes and shoes for each 3-week measurement.
The subjects in Evans’s study were poorly controlled during the training program. Also, there was no standardization regarding prior weight training experience.
The majority of studies in healthy and active humans show that chromium is not effective as a fat loss supplement.
These studies have reported… 8 to 14 weeks training with chromium supplementation didn’t give any extra benefits.
Grant and coworkers
They reported that chromium supplementation without training may result in an increase in body weight. They also explain a non-exercising group of obese women gained almost 2.0 kg of body weight over a 9-week period.
It also reported the obese women did result in about a 1-kg decrease in body weight. This result was achieved with a 9-week exercise program and chromium nicotinate supplementation.
An exercising placebo group and an exercising group consuming a chromium picolinate supplement. They did not experience any change in body weight, FFM, or fat mass during the 9-week period.
This was the first study to report a good weight-loss effect with chromium nicotinate. Unsure why the chromium nicotinate group responded better than the chromium picolinate group.
Although this study did report a significant effect from chromium supplementation. It is in the minority. It is safe to say that the majority of research does not support the use of chromium as a weight-loss supplement.
Safety and Toxicity
In addition to questioning the effectiveness of chromium! Some researchers have questioned the safety of chromium.
The National Research Council claims that toxicity from chromium occurring in the diet is so low. There is a wide range between the amount normally consumed and the amount that has harmful effects
However, the National Research Council did not consider the effects of supplemental chromium. Chromium is a metal and must be chelated to another compound to increase absorption.
The most popular compound for chelation of chromium is picolinic acid. Chromium picolinate is stable in the body. However, this stability could lead to an accumulation of cells, which could result in cell damage.
Chromium picolinate has been associated with a 24% decrease in transferrin saturation of iron. Transferrin is the irontransporting protein in the plasma.
Because chromium competes with iron for transferrin. There is an increase in chromium levels in the blood can reduce transportation and distribution of iron. It can ultimately affect the blood oxygen binding capacity.
Additional studies have reported that picolinic acid may prevent the availability of minerals for metabolism and tissue function by increasing mineral excretion.
In vitro studies have reported that picolinic acid alters cell size, shape, and function.
In addition, chromium supplementation has been associated with kidney failure and rhabdomyolysis. In both case reports, the individuals were consuming chromium above the recommended dosage.
A study was presented at the 1999 Annual Meeting of the American Chemical Society. Dr. Vincent from the University of Alabama reported about chromium picolinate. At 100 times less than the concentration found in human body tissue after long-term use. This will react to form chromium II, which interacts with oxygen to produce hydroxyl radicals.
These molecules are known to alter the DNA structure. Dr. Vincent also reported, when vitamin C is combined with chromium picolinate the potential for damage is even greater.
As Lefavi and coworkers pointed out in their review of chromium! Potential safety issues related to chromium challenge its effectiveness as a food supplement. More research must be carried out on potential adverse reactions that have been reported from Vitro studies.
