Will i gain weight or expand in my physical appearance if im hav'g wholegrain bread everyday 4 my breakfas?it does contain flour that's fatening rite?

Not necessarily: Weight gain and loss is largely simple math. How many calories did you eat today? How many did you burn? There is, however, growing evidence that highly refined, rapidly abdorbed carbs do contribute to weight gain, sugars, starches, prepared and processed foods. Try to eat more whole fruits (not fruit juice) and vegetables, modest amounts of whole grains, and avoid sugar beverages and starches.

Not that simple: 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 & bars, lean meats, poultry
