It is good to take a fat loss supplement 30-40 minutes before breakfast. When you are asleep, your metabolism rate is slow too. The only way to kickstart your metabolism and fat burning process is by taking a pill on an empty stomach.
Take maximum two doses of supplement per day. Limit your intake to one gram of protein per pound to reduce weight. Do not go beyond the recommended amount of dosage otherwise it may cause you some health issues.
Cycle on fat-burning supplements for three to four weeks. Take a break for at least two weeks before retaking them. Observe your condition when you consume them again. If they do not produce any adverse effects on you, continue with them but if they do, switch to the other one.
