There's no real magic to boosting your metabolism - no special foods, drinks, or pills...
What boosts your metabolism and oddly enought helps to lose weight at the same time
is consistent behavior.
What does your meal plan look like on a five day basis
What does your strength training plan look like on a five day basis
What's your cardio plan for those same five days
the answer is in those three questions.. not in a bottle.
The six reasons why it's hard:
Stress - If a person stress eats -then yeah that makes a difference but finding something to do other than emotional eating is your answer -not a pill
Metabolism - a lot of people kill their metabolism by years of crash dieting -they loose 20lbs then gain it all back in months - repeat cycle... Dieting is bad for metabolisms, in my estimation... Lifestyle changes are what will work - a realistic calorie range that has foods you do enjoy and doesn't leave you feeling deprived is the way to go... Strength training and building muscle (no you won't bulk up) helps immensely with metabolism (muscle is the reason why it's said men lose weight easier than women do,b ecause they have more muscle) but being consistent is what your metabolism needs..
Appetitie - Find the foods that fill you up - proteins are low in calories and tend to be quite filling -
Water - watching sodium intake and making sure you're drinking enough water -helps a lot with water retention
Energy - making sure you're eating enough helps with energy and have a regular workout schedule
Hormones - hormones get the blame for a lot of things -including bad behavior on the part of some women - I've never been clear why women are suprised by the fact that they get their period every month - did they miss that day in school when they sent the boys out of the room and showed a film? keep a calendar of your moods as they are based on your cycle... and find ways to work with your body - and know how your body works... it's your body and only your body. and if there's a real pattern there - talk to your doctor about options...
