I have used many essential oils, including slimming essential oils from some professional brands. I feel that it is not enough to rely on essential oil alone, but it must be combined with exercise. Grape seed is base oil and has no weight loss effect. Grapefruit can help eliminate orange peel tissue. The effect of essential oil on weight loss is slow, but it only helps to accelerate circulation and detoxification. Instead of relying on essential oils, it is better to diet, exercise more or take diet pills.
