What's the best weight gainer pill or shake that actually works. want to gain 15 to 20lbs by nxt month. please help?

Fat or muscle: You can only gain weight in 3 ways. 1.More calories eaten than used in activity = more fat. 2. More muscle bulk/weight added through weight or resistance type training. 3. Water retention which is not a good thing and is a sign of illness. Not good. All carbohydrates and protein give 4 calories/gram. All fats give 9 calories/gram. With liver damage and on bc pills, i advise healthy foods + #2.

HealthTap Dr's can't: endorse specific products. Eat healthy foods high in calories. Eat 6 meals /day. Work on strength training to build large muscle groups. Work out w heavier weights w fewer repetitions. Sleep at least 8 to 9 hrs/night. Hydrate well w water. Foods to help w weight gain: almonds, cashews, pecans, sunflower seeds, flax seeds, walnuts, hummus, avocados, granola, trail mix, dried fruits, protein shakes
