Hello, im looking to loose up to 40 pounds in about 3weeks or a little more because im going on vacation, what is the fastest way to loose weight?

To much in 3:weeks: Sorry, but to lose 40 pounds in 2:weeks is not safe. What i can recommend is tu reduce carbo, sugar, increase excescise, drink plenty water, eat small amount 4 to 5 times per day. If you are female reduce calories between 1200 to 1300, male between 1400 to 1500 per day. Go to your pcp and found causes, any general medical condition, metabolic abnormalities, etc.....

Do not: Losing weight quickly is not healthy. Stored toxins in fat are released quickly and can make you feel sick. Simple sugars and processed carbs should be avoided or limited. This includes any flour product. The fine grind makes absorption quick, and spikes your blood sugar which increases Insulin and promotes weight gain. Good fats such as olive oil and coconut oil are fine in sensible amounts.
