This is because the body's metabolism slows down when you sleep. One of the most recommended times to take your fat burner is actually first thing in the morning. Drink it together with your morning coffee or with breakfast. Why? As we explained above, fat burners give you energy.
Taking an early morning will help you wake up and get moving, give you the energy you want to go through your day and can even help you digest your breakfast faster. In addition, if you have one of the fat burners that suppress appetite, it means that you will not eat such a large breakfast, which also helps to reduce caloric intake. You can quickly develop nausea or cramps, so the best time to take fat burning is just before meals or snacks. Take one before breakfast, lunch and dinner, and the fourth in the afternoon.
Thermogenic fat burners stimulate hormonal reactions and encourage the body to use fat as its main source of energy instead of carbohydrates. Taking fat burners during your rest periods turns those periods into a kind of continuous passive fat burning session. If you take a fat burner after a workout or during daylight hours when you're not exercising, it can have a passive fat-burning effect. I would not recommend taking fat burners on an empty stomach or after longer periods of fasting.
As you may already know, fat burners are usually stimulants, but some of them work the other way around; instead of giving you more energy to burn calories, they suppress your appetite so that you consume fewer calories. Eating as few calories as humanly possible could help you maximize your weight loss, but not all that weight will be body fat. A recent study by Northumbria University and some other studies have shown that fasting exercise in the morning can increase fat oxidation and promote lipolysis (the breakdown of fat stores, especially adipose tissue), allowing you to burn up to 20% more body fat. Fat burning, or fat oxidation, takes place in virtually every cell of the human body every day.
Press pause and take a break from your routine so that your body can purge its system and reduce the body's resistance to fat burner ingredients. This is what fat burning supplements intend to do; take stored fat and allow the body to oxidize it and use it as fuel (also known as burned). Like any good supplement, fat burners only aim to isolate these hard-working ingredients and supplement your diet to match your fitness goals. The best way to know if you need a break from your fat burner is to evaluate how you feel when you're on it.
Unfortunately, this approach can lead to increases in blood cortisol and decreased testosterone, which will slow you down significantly in terms of muscle gain and fat loss. A fat burner gives you energy and stimulates your metabolism to burn fat, and it does so whether you're active right now or not.
