14. How To Burn More Fat Through Exercise

An Alkaloid That Burns Fat

After we exercise, our body's oxidation of fats and carbohydrates is determined by the depth and length of the activity. A new study analyses the outcome of drinking an alkaloid, p-synephrine, on the burning of fats and refutes the value of miracle diets: it isn’t feasible to lose greater than a kilogram of fat monthly.

New research published within the British Journal of Clinical Pharmacology analyses p-synephrine's position in burning fat for the duration of rest and exercise. This alkaloid can also be discovered in nature, though at low concentrations in a large type of citrus fruits like oranges, mandarins and grapefruits, and commercially at better concentrations in extracts of bitter orange (Citrus aurantium).

According to Juan Del Coso, a researcher from Camilo José Cela University and the lead researcher of the study, There is very little scientific information on this substance's effects on metabolism and the oxidation of energy substrates during exercise or on the side effects of the continued consumption of this substance.

Energy Booster

On account of its chemical similarity to ephedrine, a nerve stimulant), and the substance's activation of ?3 adrenergic receptors, it has turned out to be a widespread food supplement, traditionally incorporated in weight loss products. According to Del Coso, The advantage of p-synephrine is its reduced activation of ?1 y ?2 receptors and consequent weak influence in raising arterial tension and heart rate, which mean the substance has fewer side effects than other adrenaline stimulators.

The reason of the investigation is to determine the consequences of acute consumption of 3 mg p-synephrine per kg body mass on energy metabolism and the rate of fats and carbohydrate oxidation for the period of rest and activity.

In a randomised, placebo-controlled, double-blind, experimental study, 18 subjects underwent two experimental trials: after consuming p-synephrine (3mg/kg) and after taking a placebo or control test.

An hour after eating the substance, energy expenditure and arterial tension were taken before and after exercise, using a static bike. Immediate p-synephrine ingestion had no outcomes on energy expenditure, heart rate or arterial strain. Del Coso further explained, However, the substance produced a notable change in substrate utilisation during exercise: p-synephrine ingestion pre-exercise increased the rate of fat oxidation and reduced carbohydrate oxidation at low and moderate intensity.

Actually, p-synephrine multiplied participants' highest potential to burn fat, even though it didn’t alter the intensity at which this was achieved. This data means that p-synephrine dietary supplements could be priceless to develop fats oxidation by 7g per hour of physical activity.

No Miracle Diets

The maximum rate which was observed for fat oxidation throughout exercise, in this case in cyclists, was 0.7 g/min. That would propose that in a satisfactory scenario, a person would burn 42g of fat after an hour of exercise with that intensity.

The researcher continued on, This means the weight changes we experience when we start exercising are not based on fat loss, but mainly on fluid loss. This is why the majority of ˜miracle' diets and slimming programmes produce a ˜rebound' effect due to the recovery of the lost fluid
