Make sure that you hydrate yourself throughout the day with water. Try to stay away from soft drinks because they can cause water gain.
Eat small meals and snacks during the day instead of 3 large meals. This helps to keep your insulin regulated while you are awake.
Avoid working out with an empty stomach. Try eating high protein snacks such as unsalted peanuts, low cal protein bars such as Beachbody Protein Bars.
Finally a good support team from Family and Friends will help to keep you motivated and on track to losing those pounds.
